Title:
MOTOR DRIVING DEVICE WITH VEHICLE SPEED REDUCER
Document Type and Number:
Japanese Patent JP2016205452
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor driving device including a vehicle speed reducer in which deformation of an outer ring of a roller bearing is restricted and it produces a superior supply of lubricant into the roller bearing without decreasing a bearing function.SOLUTION: There is provided a motor driving device with a vehicle speed reducer that is a parallel axis gear speed reducer provides in which a plurality of gear shafts constituting the parallel axis gear speed reducer are supported at both ends through a roller bearing 34b fitted into a bearing fitting hole 32b disposed at a speed reducer casing 20bL storing the parallel axis gear speed reducer, and a groove 45 for communicating between a space G1 storing the speed reducer and an internal space G2 of the bearing fitting hole is disposed at an inner peripheral surface of the bearing fitting hole 32b into which the roller bearing 34b is fitted at a position where it does not cross with a load acting line acting on the roller bearing 34b through engagement of the gears.SELECTED DRAWING: Figure 5
