ELECTRIC DRIVE WITH PLANETARY REDUCTION GEAR Russian patent published in 2019 - IPC F16K1/16 F16H1/28 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Electric drive with planetary reduction gear includes tight housing, input shaft connected with electric motor, planetary reduction gear and output shaft. On the output shaft there is a splined bushing, which end rests against the housing base and is made with a profiled platform, on which symmetrical to the axis passing through the splined bushing diameter, two ball-bearing elements of the drive disconnection mechanism are fixed in extreme positions, which when in contact are in contact with a pair of end position sensors mounted opposite each other, and a pair of position monitoring sensors, also installed opposite each other and located in four pockets of the housing bottom.

EFFECT: providing automatic disconnection of electric drive at turning of output shaft by angle of 90° in forward and reverse direction for use in structures with rotary mechanisms, and the electric drive position sensor enables to track the position of the output shaft, which enables integration of the electric drive into feedback control systems.
