Special single-row deep groove ball bearing for guide wheel of automobile door

Abstract

The invention relates to a special single-row deep groove ball bearing for a guide wheel of an automobile door, which comprises an outer ring, an inner ring, rolling bodies and a connecting mandrel, wherein a seal ring is fixed on the outer ring; and excircle plastic is arranged on the outer ring. The special single-row deep groove ball bearing is characterized in that a retainer is also included; the inner ring is an integral inner ring; the rolling bodies are spherical ones which are uniformly distributed between the outer ring and the inner ring; the inner ring is mounted and fixed through the connecting mandrel; and the spherical rolling bodies are uniformly spaced by the retainer. According to the invention, the original two separable inner rings are converted into one integral inner ring; and the meanwhile, the ball bearing is changed from the original full balls with no retainer to full balls with the retainer. Thus, the bearing can bear the corresponding load, the rotation resistance is reduced, and the bearing is less prone to abrasion in case of high-load application. When the bearing is mounted on an automobile door, the resistance is smaller than before during movement of the door, and the service life of the bearing is longer than before; and due to satisfactory matching, no vibration or noise is generated when the automobile runs at a high speed.

Description

technical field [0001] The invention relates to single-row deep groove ball bearings of models 5F1721F-2RS1STN1, 6F2126F-2RS1STN1, 10F3228F-2RS1STN1, 8F2426F-2RS1STN1, 6F2124F-2RS1STN1 and other models for automobile door guide wheels, which are applied in the field of automobiles. Background technique [0002] The guide wheel bearing for commercial vehicle moving doors is mainly composed of outer ring, outer ring plastic, two separable inner rings, rolling elements, grease, sealing ring, and connecting mandrel. The rolling body is installed between the outer ring and the inner ring. The rolling body is spherical. After the ball is filled, the two separated inner rings are fixed by connecting the mandrel and riveted. The sealing ring is fixed on the outer ring to prevent Dust and prevent grease leakage, grease plays the role of lubrication and the formation of oil film. This bearing was originally assembled on the mobile door of a commercial vehicle and used as a guide whee...

AI Technical Summary

Problems solved by technology

This bearing was originally assembled on the mobile door of a commercial vehicle and used as a guide wheel. Since the bearing does not use a cage and the inner ring is made of two halves, the resistance is too large when the bearing rotates, and the bearing wears out quickly after a period of use. , will produce axial and radial gaps, so that the gap of the commercial car door will also become larger. When the car runs at high speed, the door will vibrate and make noise
