Bearing with inner ring serving as sleeve piece

Abstract

The invention discloses a bearing with an inner ring serving as a sleeve piece. The bearing is characterized by consisting of an outer ring (1), a plurality of cylindrical rollers (2), a retainer (3) and the inner ring (4), wherein the cylindrical rollers (2) are arranged in the retainer (3); the retainer (3) is positioned between the outer ring (1) and the inner ring (4); flanges are fixed through inner edge strips at two ends of the outer ring; and the inner ring consists of a flange-free internal thread ring (5), an open spring washer (6), a left flange external thread ring (7) and a right flange external thread ring (8) so as to form an inner ring, of which flanges are fixed through outer edge strips at two ends of the inner ring. Flanges of the inner and outer rings are fixed flanges, relative movement of the inner ring and the outer ring can be better limited, and the axial positioning accuracy is higher. The bearing is more convenient to mount and has longer service life.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering bearings. Background technique [0002] At present, there is a problem when rolling bearings and cylindrical roller bearings bear positive and negative bidirectional axial loads: if the outer ring and inner ring are parts with fixed ribs at both ends, the slider or roller cannot be installed inside and outside. inside the raceway of the ring. Now there are two main solutions to this problem: one is to use the NUP type with fixed ribs at both ends of the outer ring and a fixed rib at one end of the inner ring and a movable gasket retainer at the other end; The NFP type has a fixed rib at one end and a fixed rib at one end of the outer ring and a movable gasket retainer at the other end. The disadvantage of using these two methods is that the axial accuracy of cylindrical roller bearings (or rolling bearings) depends on the user's installation conditions, and the axial accuracy is p...

Problems solved by technology

[0002] At present, there is a problem when rolling bearings and cylindrical roller bearings bear positive and negative bidirectional axial loads: if the outer ring and inner ring are parts with fixed ribs at both ends, the slider or roller cannot be installed inside and outside. inside the raceway of the ring

The disadvantage of using these two methods is that the axial accuracy of cylindrical roller bearings (or rolling bearings) depends on the user's installation conditions, and the axial accuracy is poor; the movable gasket retaining ring is driven by the roller or slider to rotate Possibly; additional devices are required for movable spacer retainer for axial and circumferential fixation
