Abstract

A compressor of the rotary type is driven by a motor via a gear wheel arranged on the shaft of the compressor and cooperating with a gear wheel arranged on the shaft of the motor, the gear wheels and the shafts being enclosed in a gear housing. The motor is fastened to a detachable wall part of the gear housing, and the motor shaft is journalled solely in the bearings of the motor and protrudes into the gear housing through an opening in the wall part. The opening is provided with sealing means which prevent a medium from forcing its way out of the gear housing. The gear wheels are accessible for dismantling and assembly when the wall part together with the motor is detached from the rest of the gear housing.
