Abstract

The invention relates to a bearing of a multi-layer roller structure. The bearing comprises a bearing inner frame and a bearing outer frame. A roller assembly is arranged between the bearing inner frame and the bearing outer frame and comprises an outer roller mechanism and an inner roller mechanism. The outer roller mechanism comprises a plurality of annularly arrayed outer sliding sheets, and multiple balls are arranged on the outer layer of each outer sliding sheet. The outer sliding sheets are in contact with the inner wall of the bearing outer frame. The inner roller mechanism comprises a plurality of T-shaped support sheets. The tip of each T-shaped support sheet is embedded into a gap between the corresponding adjacent outer sliding sheets, and multiple balls in contact with the outer wall of the bearing inner frame are arranged on flat sides of the T-shaped support sheets.

Description

technical field [0001] The invention relates to a multi-layer roller structure bearing, which belongs to the field of bearings. Background technique [0002] Traditional bearings are composed of a simple outer frame, inner frame and rollers. The rollers directly rub against the outer frame and inner frame to realize the rotation of the bearing. Because of the limitations of the shape and material of the rollers, it is difficult to avoid the rollers from the outer frame and the inner frame. At the same time, in many equipments, the bearings also bear large radial and uncertain impacts, and the rollers are easy to produce pits on the inner and outer frames of the bearings, which affects the bearing performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the problem of poor durability of bearings in the prior art and provide a durable and stable bearing. [0004] The technical solution adopted by the present ...
