    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: The grease-sealed bearing is formed on rolling surfaces (4) of rings (2, 2) of the bearing (1) with oxide layers (5) having a thickness of 0.1-2.5 microns, the development of peculiar peeling on the rolling surfaces of the bearing can be prevented. If it is used as a bearing for an alternator or the like, its duration can be increased.

    摘要: In a thrust needle bearing employing lubricating oil and having rollers held by a cage and rolling on races, the value of the arithmetic average roughness Ra of roller is 0.03 to 0.15 μm. Even when the bearing is used under the conditions where lubrication is lean or lubrication characteristics are wrong, the rolls can be prevented from being worn at the contact parts thereof with the pocket guide face of the cage and the life of the rollers and races can be increased.
