<P>PROBLEM TO BE SOLVED: To provide a railway vehicle driving unit, in which a temperature rise is suppressed and which has improved lubricating performance. <P>SOLUTION: This railway vehicle driving unit 12 includes a reduction gear housing 13, an input side rotating member 14, carriers 24, 25, curved plates 17, 18, inner pins 19, 20, an outer pin 21, axle bearings 26, 27, spindle bearings 30a, 30b, and eccentric bearings 32, 33. The inner pins 19, 20 are abutted to the curved plates 17, 18, thereby inhibiting the rotation motion while allowing the revolution motion of the curved plates 17, 18. The outer pin 21 engages with the outer peripheries of the curved plates 17, 18 to reduce the speed of the reduction gear housing 13 and rotate the same with respect to the input side rotating member 14. Grease is previously retained in the interiors of the axle bearings 26, 27, the interiors of the spindle bearings 30a, 30b, the interiors of the eccentric bearings 32, 33, abutting parts between the revolution members 17, 18 and the rotation regulating members 19, 20, and engagement parts between the revolution members 17, 18 and the outer peripheral engaging member 21. <P>COPYRIGHT: (C)2011,JPO&INPIT |
