Roller bearing constituted only by holding bracket and roller

Abstract

The present invention discloses a roller bearing composed of a hold frame and rollers. The roller bearing includes a first annular end frame and a second annular end frame separated along the axes in axial direction and several transverse septas (7) uniformly distributed with equal space along the circumferences of the two end annular frames for connecting the two annular end frames. The outer surface of the transverse septa (7) is even with the outer diameter surfaces of the two annular end frames, the axes of the transverse septa (7) is vertical to the inner surface of the two annular end frames (3, 4), a roller (8) is disposed between each two transverse septas (7), the diameter size of the roller (8) is larger than the radial width size of the two annular end frames, the axial length of the roller (8) is smaller than the distance between the inner surfaces of the two annular end frames. The roller bearing has strong radial bearing ability, its structure is more simple and saves more material, the roller can be prevented from extrusion and abrasion, the machining technics is simple, the material and machining precision requirement is low; it saves manpower and time, and has low manufacturing cost.

Description

Technical field [0001] The invention relates to a rolling bearing for mechanical transmission, in particular to a roller bearing consisting of a cage and rollers only. Background technique [0002] The structure of the roller bearing in the prior art without inner and outer rings, that is, consisting only of a cage and rollers, is as follows. It includes a first ring-shaped end frame and a second ring-shaped end frame that are axially spaced along the axis and connecting the two A plurality of transverse partitions of a ring-shaped end frame, the plurality of transverse partitions are distributed at equal intervals along the circumference, the axis of the partition is perpendicular to the inner surface of the two ring-shaped end frames, and a roller is movably embedded between every two transverse partitions. For the column, the radial width of the first and second annular end frames and the radial thickness of the transverse partition are smaller than the diameter of the roller....

AI Technical Summary

Problems solved by technology

However, the roller bearings of the prior art that only consist of cages and rollers also have the following disadvantages: 1. Since the rollers need to be pressed in with external force, their assembly is laborious, especially the assembly process will inevitably cause damage to the rollers. Crushing and wear directly affect the service life of the roller bearing

2. Since the diaphragm needs to limit the radially inward and radially outward positions of the rollers at the same time, objectively the diaphragm itself is required to have a more complex structure, its processing technology is complicated, and its material and processing accuracy are required to be high. Therefore, its manufacture is labor-intensive, time-consuming, and its manufacturing cost is relatively high.
