Accessories Connection of motor and encoder Couplings Bellows and spring washer couplings Bellows couplings provide cost-effective connection of the motor and encoder. They are also able to correct any angular errors between the drive and encoder. Spring washer couplings are used with high speeds. Order code 8.0000 . 1 X 02 .

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 com- Depending on the type of coupling, particular attention should be paid to radial pensated, thereby reducing the load on the bearings to a minimum. A distinction shaft displacement which should be kept to a minimum. should be made between three different kinds of alignment error: radial, angular and axial displacement. 434 www.kuebler.com Fritz Kbler GmbH, subject to errors and changes. 08/2013120 AccessoriesAccessories Connection of motor and encoder Couplings Bellows and spring washer couplings Metal bellows-type couplings (.1102, .1202 and .1502) Spring washer-type couplings (.1302 and .1402) Metal bellows-type couplings are recommended as an inexpensive type of Spring washer-type couplings are used mainly in those cases where high coupling. They are also suitable for compensating larger angle displacements. 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.

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. Fritz Kbler GmbH, subject to errors and changes. 08/2013 www.kuebler.com 435 H8 d1 H8 d2 19 Accessories
