Bearing structure for axle

Abstract

The invention discloses a bearing structure for an axle. The bearing structure comprises rollers, an inner ring, a check ring, a spring retainer ring, a paper container, a planet gear and a sun wheel, wherein the rollers are symmetrically arranged on the outer surface of the inner ring, and are matched and connected with the inner ring; the spring retainer ring is arranged in the middle of the check ring, two ends of the spring retainer ring are tightly connected with the paper container and the inner ring; the check ring is arranged between the spring retainer ring and the rollers, the check ring is adhered with the side walls of the rollers; the outer side surface of the paper container is tightly connected with the planet gear; the outer surface of the planet gear is tightly connected with the interior of the sun wheel. The bearing structure is simple and is strong in bearing capability, an optimized design of the bearing is realized, compared with a common mechanical bearing mechanism which is designed by experiment, the bearing capability of the bearing structure disclosed by the invention is increased by 9.6 percent, so that the deflection error is favorably reduced, the contact stress of the rollers and the inner ring is relatively uniformly distributed; the bearing structure is compact in structure, stable to run, long in service life, light in weight and suitable for being popularized and used.

Description

technical field [0001] The invention relates to the technical field of construction machinery bearings, in particular to a bearing structure for an axle.

[0003] Chinese patent CN103790948A describes a cylindrical roller bearing. The bearing unit includes an inner ring, a cage and rolling elements. There are two eccentric raceways on the outside of the inner ring. The rolling elements are clamped on the two raceways of the inner ring. The retainer is erected on both sides of the raceway, and an inner hole shared by the two raceways is provided in the middle of the inner ring, and ribs are provided on both sides of the raceway. Compared with the prior art, the present invention replaces the ordinary double row Cylindrical roller bearings do not make the shaft into an eccentric shaft, which is easy to install, but this also reduces the bearing pressure and greatly reduces the service life of the bearing, but the connection between the existing bearing structures is not tight enough, and the service life is short , the manufacturability is poor, and the weight of the parts is heavy. Therefore, a bearing structure for the axle is proposed
