  • Patent number: 11136051
    Abstract: A railcar axle box includes an axle box main body accommodating a bearing supporting an axle. The axle box main body includes: an inner surface defining an accommodating space accommodating the bearing; a first side surface provided at an outer side of the inner surface and at one car width direction side of a car width direction center of the accommodating space; and a second side surface provided at an outer side of the inner surface and at the other car width direction side of the center. A shortest distance between the first side surface and the car width direction center of the accommodating space and a shortest distance between the second side surface and the center are equal to each other in a car width direction.

  • Patent number: 6688001
    Abstract: There is provided a method of working a plain bearing and a working apparatus of the plain bearing, which make it easy to perform working by forming a plurality of inclined surfaces of different angles in portions on both sides of the inner peripheral surface of the bearing alloy metal of the plain bearing in the axial direction thereof. In the working method and apparatus, a working holder 18 is provided which has a groove 20 extending on the inner peripheral surface in the peripheral direction and portions on both sides of the groove in the transverse direction formed in step-like shape, a half bearing 11 is housed in the working holder 18, and both ends of the half bearing 11 in the peripheral direction are pressed by use of pressing means 24. Then, the half bearing undergoes plastic deformation so as to be fitted into the groove and both sides of the half bearing in the axial direction thereof come into abutment with the edges 22, 23 of the step-like portions and are deformed in a polygonal line form.
