MOTOR-DRUM Russian patent published in 2006 - IPC B66D1/22 B66D3/20 

FIELD: mechanical engineering; winches.

SUBSTANCE: invention relates to load-lifting mechanisms, particularly, to drives of winches and hoists. Proposed motor-drum consists of two supports. Flanged motor, and planetary multiflow reduction gear placed inside drum housing. Support journal gear carrier projecting from reduction gear is rigidly connected with first support of drum. Carrier is provided with second support journal getting into drum, and housing of reduction gear and drum rest on both said support journals. With motor mounted from outside, flange of motor is attached to flange of first support of drum and first support of carrier, and is connected by shaft through sleeve coupling with sun gear of reduction gear passing through said support. With motor mounted inside, flange of motor is connected with second support journal of carrier and by shaft, through sleeve coupling, it is connected with gear of reduction gear passing through said support.

EFFECT: simplified design, improved repairability and reliability of motor-drum.
