Long-service-life roller bearing

Abstract

The invention discloses a long-service-life roller bearing which comprises an inner ring, an outer ring and rollers. The rollers are located between the inner ring and the outer ring, containing grooves are formed in the top of the inner ring, a fixing rod is arranged in each containing groove, and arc-shaped movable blocks are symmetrically arranged in each fixing rod; a limiting block is arranged above each arc-shaped movable block and fixedly connected with the inner wall of the corresponding fixing rod; a first disc is fixedly connected to the tops of the fixing rods, the bottom of the first disc is fixedly connected with a first sealing ring, and the first disc is sleeved with a second disc; and a second sealing ring is arranged at the bottom of the second disc, the first sealing ring and the second sealing ring are located on the two sides of a slideway, a heat conducting pipe is arranged on a side wall of the slideway, and the side, away from the slideway, of the heat conducting pipe extends to the outer side of the outer ring. According to the long-service-life roller bearing, dust is prevented from entering a rail, the service life of the roller bearing is prolonged, and the equipment using cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a long-life roller bearing. Background technique [0002] In mechanical equipment, the use of bearings is very common. In some mechanical equipment with special purposes, there are higher requirements for the performance of bearings, such as bearings in transportation equipment such as forklifts. Although the speed of forklifts is not fast, but The working environment of the forklift is relatively harsh, and the dust is relatively large, and the dust is easy to fall into the bearing, resulting in damage to the bearing and eventually equipment failure, which brings great inconvenience to the user. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a long-life roller bearing. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A lo...
