be used.

HARDWARE

Only DIN standard hardware is used in TK couplings. All hardware should be grade 8.8 or higher. Standard hardware is either zinc plated or parkerized. Special hardware, such as stainless steel, is available on request. All screws should be torqued according to table 3.

MISALIGNMENTS

Values given in table 4 are valid for a coupling rotating at

• max. 1500 1/min. If the rotating speed differs from this value,

the effect can be calculated with the factor Fkv. N Fkv 500 1/min. 1,60 1000 1/min. 1,20 1500 1/min. 1,00

INSTALLATION & MAINTENANCE

General installation instructions for a TK coupling:

• Align the coupled machines according to the values

listed in table 3.

• Clean the outside of the coupling.
• Measure the shaft and the coupling bore to check the

fit.

• Heat the hub to max. 130 ⁰C if required, and cool the

shaft with liquid nitrogen.

• Depending on the drive, slide the machines against

each other while paying attention to the required distance between shaft ends, S in table 2, and install the pins and buffers, or install the pins and buffers first and then move the machines.

• Double check screw tightness and install the coupling

cover (Cover sold separately). Servicing a TK coupling:

• A TK pin coupling is normally maintenance-free,

requiring only visual inspection.

• Inspect the rubber buffers for signs of wear, cracks or
• misformation. A damaged buffer should be replaced

with a new one.

• To ensure the longevity of the buffers, care should be

taken to prevent debris from getting between the buffer and the hub bore.

An incorrectly tightened screw may come loose and damage the coupling

• r other parts of the

drive. Altering the coupling by machining or welding is strictly prohibited. Inaccurate alignment will lead to premature coupling failure. Locking hardware, such as lock nuts, should be replaced if removed.

GENERAL WARRANTY TERMS

Warranty terms for TK couplings: – The customer has provided MFG with adequate data of the drive. – Screw tightening torques and alignment precision has been documented during installation. – The coupling has been installed in the drive it was first designated for, and the drive has not been altered after designation. – Only hardware supplied with the coupling have been used. – The coupling has not been damaged during installation by excess heat or by damaging it. – The coupling has been stored appropriately, away from solvents and other chemicals. – The customer has not altered the coupling by machining, welding, etc. – Operating temperature has not exceed the maximum temperature allowed for the type of buffers used.

Indirect expenses, such as loss of production, generated from replacing the coupling are not covered.
