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.
