GEAR-FLEX COUPLING
CROWNING OF GEAR TEETH (OPTIONAL) The straight line tooth form is known to transmit high torque when the centers of axis are in complete alignment. Where there is any displacement, however, this will cause the contact area to localize on tooth surface (at the end of tip of the tooth) thereby causing damage to surfaces of the teeth. While rotating the load is continually changing location, introducing sliding between the two gears. Crowned gear teeth resist the wear thus developed. Because of the fully crowned design, end bearing does not occur, and the tooth bearing remains near the center section of the tooth, thus utilizing the additional strength available at the tooth centre.
The LOVEJOY Gear coupling has a unique crowning for the tooth surface which is designed after full consideration of the relationship between tooth forms & tooth width so that the contact stress on the tooth surface will not vary significantly even where relative movement is present. As for the tooth tip, the crowning is applied & the tooth is designed to minimise the top clearance between teeth when they are mated. The LOVEJOY Gear coupling has a crown tooth form so as to give maximum tooth thickness at its center. Where there is a relative misalignment between the driver & driven shaft, it is necessary that the tooth which comes between the teeth of its counterpart be permitted to oscillate. The internal teeth of the sleeves have a std. form whereas the external teeth of the hub take a special form.

GEAR-FLEX COUPLING
HALF FLEX COUPLINGS WITH FLOATING SHAFTS
A floating shaft can eliminate the need for additional bearing support along spanning shaft because shaft is supported at ends by connected equipment through the half flex couplings. These are generally used for the applications of cooling tower fans.
Flexible hubs on floating shaft (Fig. 3a ) Assembly of flexible hubs on the floating shaft allows for easier replacement in case of wear & allows the rigid hubs with their increased bore capacities to be used on the connected equipment shafts. This frequently means a smaller coupling size to be utilised.
Rigid hubs on floating shaft (Fig. 3b ) When the rigid hubs are on floating shaft, shorter shaft spans can be accommodated. Since the flexible hubs are outboard, the planes of gear mesh are further apart, providing greater misalignment capacity.

GEAR-FLEX COUPLING
LUBRICANTS 1. OIL LUBRICATION For the gear coupling, use gear oil of viscosity of 35 to 45 cst at 99°C with extra high pressure additive. Where the coupling is used under extreme overload operation, severe reversing operation or bigger angular and offset misalignment, use gear oil of viscosity of 70 to 110 cst at 99°C. A. First filling must be ample. B. After about 3 months’ operation, the coupling should be overhauled and drained of used oil to remove abrasion particles, and refilled with fresh oil. C. Subsequent refilling or replacing of oil should be made every 1 year by use of oil plug holes. 2. GREASE LUBRICATION Grease lubrication is somewhat inferior to application of gear oil. Coat the coupling case and coupling center with the specified grease until the teeth are submerged in grease, assemble the coupling, tighten the bolts and then supplement grease through oil plug hole by use of grease gun and so on. Replacing time of grease is same as gear oil, but replace old grease with new grease in full by overhauling the coupling. 3. RECOMMENDED LUBRICANTS Recommended Grease is RSG (Rathi Special Grease) having δg = 910 Kg/m3.
Refer Table ‘C’ for grease qty. reqd. per coupling size.

INSTALLATION INSTRUCTIONS FOR STD. LFG / LHG COUPLINGS
(A)
BEFORE INSTALLATION
1. Remove the coupling from packing & thoroughly inspect for signs of damage. 2. Disassemble the coupling by removing nuts & bolts. Clean all the parts carefully. 3. Remove protective coatings / lubricants from bores & keyways. (B)
MOUNTING PROCEDURE
1. Slide the sleeves with internal teeth with rubber O ring on shafts before mounting the hubs. 2. Mount the hubs with external teeth on their respective shafts flushed with the faces of hubs as shown in fig. 1.
20
JAN-02
GEAR-FLEX COUPLING 3. With one machine firmly bolted down, set the equipments at a distance ‘G’ (refer table A & B) between shaft ends by using a spacer bar equal in thickness to the required gap ‘G’ as shown in fig. 2.
Deviation in standard DBSE is defined as axial misalignment (end float). For normal applications the shaft end should be flushed with inner face of the adpater. In some special cases the shaft ends may protrude beyond the inner face of the adapter or may remain inside, if required. The distance between two faces of adapter flanges is to be maintained as specified. The variation in this distance should not exceed the permissible initial axial misalignment given in table 1.
21

GEAR-FLEX COUPLING
(C)
ALIGNMENT PROCEDURE
Alignment procedure is given separately for each type of alignment, for simplicity. However all 3 types of misalignments may be present at the same time. IMPORTANT : The misalignment capabilities shown in drawings or in product literature are for dynamic conditions and variations. For optimum service from the coupling the installation misalignment (Initial misalignment) should not be more than 25% of the maximum allowable misalignments limits. Allowance should be made for any anticipated movements which will occure during operation (e.g. Thermal movements).
For Permissible INITIAL misalignments refer table A For Permissible MAXIMUM misalignments refer table B
22
JAN-02
GEAR-FLEX COUPLING
(I)
CHECKING PARALLEL /RADIAL ALIGNMENT
Check the parallel/Radial alignment with the help of straight edge resting squarely on both the hubs at 4 places 90° apart. The deviation in the readings should not exceed the permissible initial parallel misalignment mentioned in table A. (Refer fig. 3)
(II)
CHECKING ANGULAR ALIGNMENT
Check the angular misalignment with the help of slip gauges by inserting in the gap at 4 places 90° apart. The deviation in the values of standard gap ‘G’ is Total Indicated Reading (TIR). The angular misalignment ‘X’ in mm is half the Total Indicated Reading. The values of angular misalignment should not exceed permissible initial misalignments mentioned in table A. (Refer fig. 4).
23
JAN-02
GEAR-FLEX COUPLING (D).
ASSEMBLY PROCEDURE
IMPORTANT : If the coupling is dynamically balanced, ensure that the matchmarks are in straight line & unidirectional before bolting the assembly.
1. Insert the gasket between the flanges. Position the flanged sleeves with lubrication plugs. 2. Insert the bolts & tighten the nuts. Remember: Assemble only with the help of the fasteners furnished with the coupling. Fig. 5
3. Fill with recommended grease/oil (RSG/RSL with reqd. qty.) for lubrication. For grease quantity for respective coupling size, refer table No. C. 4. Change the grease after the interval of 6 months & the oil after the interval of 1 year or after 8000 working hours. Use Loctite to prevent the loosening of threads, if required. IMPORTANT: The necessity for shields & guards varies with individual installations. The owner or user must provide the required safety guards. Safety guards or shields are not furnished by us with this equipments.

TDM 1.0 Dangers and safety precautions Minimum flow valves have the same potential danger as pressure vessels. Therefore planning, installation, operation and maintenace shall be done according the necessary safety precautions.
1.1. Danger to persons and materials The minimum flow valves should only be operated within their limits of design and layout. No changes are to be made without our approval. Only use original spare parts. Safety regulations, site regulations and installation safety precautions are to be followed. Please follow the instructions as given in this “Installation-, Maintenance and Assembly instructions”.
1.2 Avoid dangers Maintenance of the Automatic Recirculation Valve shall only be done by trained personnel. Before disassembly, the installation has to be shut off and the valve pressureless and cooled down. Please make sure that these safety precautions can only be cancelled after ending the assembly of the valve. Please be aware that also in a pressureless valve there might still be medium. Wear protective clothing.

TDM 2.
Description The Schroedahl automatic-recirculation-valve model TDM is applied in centrifugal pump systems in order to provide an automatic leak-off flow in case of low load conditions. The application range of the series TDM with a multistage pressure let-down section is, independent of the temperature, for the operating pressures from 64 bar (a) to 250 bar (a) (900 psig to 3600 psig). The valve consists of an upper and a lower housing, each provided with a flange. The bypass housing, and as an option also the start-up housing, are located horizontally at the side of the valve. The valve trim comprises a check valve as also a control- and throttle section. The valve protects centrifugal pumps, especially boiler feed pumps, against overheating, by maintaining, automatically, a minimum flow. At flows, lower than the required minimum flow the check valve activates, by means of a lever, a vortex plug. When lifted of its seat, the vortex plug allows a flow through the pressure reduction section to the suction tank (or condensate tank). The opening characteristic is linear; the bypass flow increases when the check valve moves from its switch point further into the closes position. Because of the modulation bypass control, the total of process flow and minimum flow remains approximately constant. The check valve, shaped like a differential control piston and spring loaded, has such a high own frequency, that waterhammer is avoided. The check valve dampens pulsations because of its throttling effect on the mainflow and stabilises unstable pump characteristics in the partial load range. The housing is made from forged steel and is provided with a chromium steel liner in the check valve area. All moving parts and guides consist of alloy steel which are compatible. Alternative materials are available as options (see drawing and parts lists).
- 13 -
TDM 3.
Packing and marking The automatic recirculation valve is shipped, depending on size, in an aluminium box (reusable), skid-carton or in a wooden crate. The standard factory conservation is sufficient to protect the valve for a period of approx. 6 month (the stocking area should be dry and ventilated). If special packing or conservation is required, this should be stated with the order. Specific valve data are indicated on the valve nameplate as per sample below. The valve nameplate is attached to every valve housing.
If spare parts are required, the following valve date should be provided with the inquiry (order): production number K ........ (stamped in valve body), valve model number and part number (check parts list).
- 14 -
TDM 4.
Assembly and disassembly The automatic recirculation valve type TDM is usually installed vertically, with the mainflow upward, and directly on the pump discharge flange. The bypass housing is connected to the bypass piping (and the piping consequently to the feedwater tank or other tank), so that a recirculation flow will be possible. Other installation positions of the valve (horizontal, upside-down) are possible, if so ordered only! No special tools are required for the installation, assembly or disassembly of the valve.
4.1 Installation at the jobsite In order to prevent damage to the flange finish and/or the bolts the complete valve should be installed in the piping free of tension/ stress. Before tightening the bolts with a torque wrench (torques as recommended by the factory!), please ensure that the machined flange surfaces and packing rings are clean.
4.2 Disassembly of the TDM Remove the TDM from the piping system. Disassemble bypass housing Pos. 09. Pull the bypass trim „M“ out of the assembly (careful!). Apply a screwdriver between the collar of the control head (pos. 11) and the valvebody (pos. 01). Remove the upper body (pos. 02) from the lower body (pos. 01) by loosening the hexagon nuts (pos. 28). The check valve (pos. 07) and spring (pos. 06) can now be removed from the lower body (pos. 01). Clean all parts and check for any damages. In case of damaged seats (check valve seat or bypass seat), this should be repaired by lapping the respective parts on the seats. Replace ring (pos. 30) if required.
- 15 -
TDM 4.3 Assembly of the TDM Replace the check valve (pos. 07) with the spring (pos. 06) in the lower body (pos. 01). Now the upper body (pos. 02) is placed on the lower body (pos. 01) and the hexagon nuts (pos. 28) are tightened (check cross sectional drawing!). Carefully insert the bypass section „M“ in the valve body and as certain, that lever (pos. 13) fits (slides) in the slot in the check valve (pos. 07). The bypass housing (pos. 09) with the bypass orifice (pos. 23) is now carefully replaced and tightened to the housing (pos. 01) with the hexagon nuts (pos. 29).
4.4 Disassembly of the bypass section Occasionally, and because of contamination of the fluid, a complete disassembly of the bypass trim may be required. At each inspection the bypass should be checked for proper operation. In case of damages, the bypass section should be removed, disassembled and the damaged parts replaced. Inspection - Check the seating of the vortex plug (pos. 12) and the vortex bushing (pos.10) for any damages. - When damaged the vortex plug and vortex bushing should be replaced as an unit. - Check glyd-rings pos. 33.1, 34.1 and 35.1 for any damages. Note In case of doubt the complete bypass assembly pos. 10-16, 21, 23, 31-36 may be replaced and the dissassemdled bypass may be send to the factory for repair. Check the drill plate pos. 23 for any damages. Replace the complete seal set.
4.5 Assembly of the bypass sections Proceed in the reverse order as per disassembly instruction above.
- 16 -
TDM 5.
Commissioning of the TDM The valve is commissioned together with the pump. When the main shut-off valve in the pump discharge piping (to the boiler or process) the specified bypass flow is maintained through the bypass section (and to the piping of the bypass system). By closing or opening the main shut-off valve, the opening and closing of the bypass can be checked. The switch point of the valve can be established acoustically (use a technical stethoscope or even a screwdriver to the ear will do). In case a manual start-up connection is provided on the valve, the minimum flow is achieved through this section. The automatic bypass is closed during commissioning and the manual start-up is opened. The automatic bypass section is spared (protected) during commissioning in this way, as the fluid might still be contaminated and/or carry solids!
6.
Maintenance instructions The TDM has been designed so, that no special maintenance is required. Maintenance is restricted to cleaning the trim together with the pump at regular intervals. After disassembly of the valve, all seals should be replaced (by new seals) before re-assembly of the valve.
7.
Warranty conditions If no special conditions have been agreed upon the order, the warranty is limited to 24 month after shipment or 8000 hours of operation. The warranty does not include damage caused by improper handling, dirt in the system or normal wear.
- 17 -
TDM 8.
Instructions in case of damages In order to judge the damages (and the cause), the following information is required: a) The production number of the valve (K .....). This number is stamped on each valve body. b) Valve model number and size e.g. TDM ... c) A description of the system in which the valve is installed.
