Abstract
A plurality of hollow rollers is located in the annular space between the inner and outer tapered raceways of a tapered bearing. Each hollow roller has an axial bore extending completely therethrough. The percent hollowness of each roller is uniform throughout its full length. The rollers may be preloaded between the races.
Claims11
A tapered bearing comprising:
- inner and outer members having inner and outer tapered raceways confronting one another to define an annular space;
- and a plurality of hollow rollers located in said annular space, each hollow roller having an axial bore extending completely therethrough, the ratio of the diameter of the axial bore to the outside diameter of each hollow roller being uniform for its full length.
A tapered bearing comprising:
- inner and outer raceway means, each having two raceways thereby providing two inner and two outer raceways confronting one another to define an annular space, one of said raceway means including a pair of races, the raceways of one of said pair of races sloping in the opposite direction to the slope of the raceways of the other of said pair of races;
- the other raceway means being a single race;
- two sets of hollow rollers located in said annular space, each hollow roller having a ratio of diameter of the axial bore to the outside diameter which is uniform for its full length.
A tapered hollow roller comprising:
- an annular wall with an outer surface which slopes at a first predetermined angle with respect to the roller axis and an inner surface which slopes at a second predetermined angle with respect to the roller axis different from the slope of the outer surface, the slopes being such that the annular wall has uniformly varying thickness from one end to the other and the ratio of the diameter of the axial bore to the outside diameter of the roller is uniform for the full length of the roller.
