Compressor assembly

5.8 Drive

The compressors of the F series can be driven by V-belts or directly by shaft couplings.

V-belt:

Proper assembly of belt drive

:

-

The pulleys of compressor and drive motor must be firmly mounted and in line.

- Only use V-belts with calibrated lengths

.

- Select axis spacing, V-belt length and belt pre-tension according to the instructions issued by

the V-belt manufacturer. Avoid belt fluttering.

- Check belt pre-tension after running-in time.

Direct drive with shaft coupling:

Direct drive with shaft couplings demands highly precise aligning of compressor shaft and

motor shaft.

Use the Bock shaft couplings „WK“ and observe the enclosed assembly instructions.

CAUTION!

Mount suitable safeguards when driving the compressor by means
of V-belts or shaft couplings!

ATTENTION! Faulty alignment results in premature failure of the coupling and

bearing damage!
