Abstract

The invention discloses a bearing provided with an axial pre-tightening compensation structure. The bearing comprises a bearing inner race, a bearing outer race and a retaining frame, wherein the retaining frame is arranged between the bearing inner race and the bearing outer race; a ball is arranged on a ball pocket of the retaining frame; a first dustproof cover is installed between a first sideof the bearing outer race and the first side of the bearing inner race; a second dustproof cover is installed between a second side of the bearing outer race and the second side of the bearing innerrace; the bearing is provided with a second side sealing surface, a second dustproof cover clamping groove and a second dustproof cover inserting bump at the second side of the bearing outer race; andthe outer edge of the second dustproof cover is provided with a second side inner sealing surface, a second dustproof cover outer edge inserting bump, a second dustproof cover outer edge inserting groove and a buffering part. According to the bearing disclosed by the invention, the buffering part and a buffering pre-tightening lug boss are designed on the second side dustproof cover so that the bearing has a pre-tightening compensation function after being assembled and can reduce the assembly cost and using cost of a customer.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing with an axial preload compensation structure. Background technique [0002] The bearing includes a bearing outer ring, a bearing inner ring and steel balls installed between the two, and the steel balls are held by a cage. In order to prevent dust and seal, some bearings also have a dust cover between the bearing outer ring and the bearing inner ring, and the dust cover is located on both sides of the steel ball. However, after the existing bearing is installed, it is easy to generate radial vibration, and the axial direction cannot be preloaded and compensated. [0003] For this reason, the applicant has carried out useful explorations and attempts, and has found a solution to the above-mentioned problems, and the scheme to be introduced below is produced under this background. Contents of the invention [0004] The technical problem to be solved by the present in...
