摘要： A railway vehicle drive unit (12) is a drive unit to rotatably drive a wheel (11) of a railway vehicle. More specifically, it includes a reducer housing (13) held on an inner diameter surface of the wheel (11), and integrally rotating with the wheel (11), an input side rotation member (14) connected to a drive source, a reducing mechanism (15) to reduce rotation speed of the input side rotation member (14) and transmit it to the reducer housing (13), a fixed member (23) arranged in the reducer housing (13) and connected and fixed to a vehicle body, axle bearings (24) and (25) to rotatably support the reducer housing 13 with respect to the fixed member (23), and lubricant oil circulating mechanisms (32) and (33) to circulate a lubricant oil between the reducing mechanism and the axle bearings (24) and (25).

摘要： A railway vehicle drive unit (12) is a drive unit to rotatably drive a wheel of a railway vehicle. More specifically, it includes a reducer housing (13) held on an inner diameter surface of a wheel (11), and integrally rotating with the wheel (11), an input side rotation member (14) having eccentric parts (16a) and (16b), and connected to a drive source, revolution members (17) and (18) supported by the eccentric parts (17) and (18) in a relatively rotatable manner, to execute revolution motion around a rotation axis of the input side rotation member (14), a rotation regulation member (119) to prevent rotation motion of the revolution member, allowing the revolution motion thereof, and a periphery engagement member (20) fixed to the reducer housing (13), to rotate the reducer housing (13) at speed reduced with respect to the input side rotation member (14) by engaging with a periphery of the revolution members (17) and (18).
