    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: To provide an electrocorrosion preventive rolling bearing assembly wherein a final machining of an electrically insulating layer and a thickness control of the insulating layer can easily and accurately be accomplished, the electrocorrosion preventive rolling bearing assembly is of a type in which an inner race (2) or an outer race (3) is formed with an insulating layer (6) so as to cover a peripheral surface thereof, which engages a housing or a shaft, and opposite annular end faces thereof. The insulating layer (6) is a thermally sprayed layer of a metallic oxide. Of the inner and outer races (2) and (3), a raceway member having the insulating layer (6) is provided at its end face with a tool reference plane (7) for a process of finishing the electrically insulating layer (6) or for the thickness control of the insulating layer. This tool reference plane (7) may be either an indented radial surface of a step (8) formed in the end face or a bare portion of the end face that is left uncovered by the insulating layer (6).
