## **Description and applications** 

Manufacturing and installation tolerances as well as the effects of temperature cause alignment errors between shafts in drive engineering which can sometimes lead to extreme overload on the bearings. 

This may result in increased wear of the bearings and may lead to premature failure of the encoder. By using couplings, these alignment errors can be compensated, thereby reducing the load on the bearings to a minimum. A distinction should be made between three different kinds of alignment error: radial, angular and axial displacement. 

Whilst with torsion-free but flexible shaft couplings, axial shaft displacements produce only static forces in the coupling, radial and angular displacements produce alternating stresses, restoring forces and moments which may have an impact on adjoining components (shaft bearings). 

Depending on the type of coupling, particular attention should be paid to radial shaft displacement which should be kept to a minimum.

## **Connection of motor and encoder** 

## **Couplings** 

## **Metal bellows-type couplings (.1102, .1202 and .1502)** 

Metal bellows-type couplings are recommended as an inexpensive type of coupling. They are also suitable for compensating larger angle displacements. 

## **Bellows and spring washer couplings** 

## **Spring washer-type couplings (.1302 and .1402)** 

Spring washer-type couplings are used mainly in those cases where high speeds and smaller angular displacements are involved. For applications where electrical insulation between rotary encoder and drive is required, the electrically insulating spring washer-type coupling should be used.

## **Installation instructions** 

1. Check shaft for displacement; see technical data for details. 

2.  Align and adjust coupling on shafts. 

3.  Tighten locking screws carefully. Avoid overtightening. 

4.  During installation protect the coupling from damage and from overbending.
