Embodiment Construction

[0015] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 to Figure 5 As shown, the structure of the needle roller according to the present invention includes a retaining ring, a cage, a needle roller and a housing, and a cage 4 is arranged inside the retaining ring 5, and a U-shaped hole 4- 2. The needle roller 3 is inserted into the U-shaped hole 4-2; the cage 4 inserted with the needle roller 3 is installed in the inner hole of the retaining ring 5, and the outer shell 1 is covered so that the outer ring surface of the cage 4 and the The inner hole of the retaining ring 5 and the inner hole of the housing 1 are matched and abutted.

[0017] When installing, put the needle roller 3 into the U-shaped hole 4-2 on the inner peripheral surface of the cage 4, put the cage 4 with the needle roller 3 inside the retaining ring 5, and the stepped surface 5-2 in the retaining ri...

Abstract

The invention relates to a needle roller structure, which comprises a retainer ring, a cage, a needle and a shell, wherein the cage is arranged inside the retainer ring; the inner toroidal surface of the cage is provided with a U-shaped hole; the needle is inserted into the U-shaped hole; and the cage into which the needle is inserted is arranged in an inner hole of the retainer ring, and is covered with the shell, so that the outer toroidal surface of the cage is pressed against the inner hole of the retainer ring and an inner hole of the shell respectively in a matching way. Due to the adoption of a resin material, the needle roller structure has the characteristics of excellent self-lubricating property, low friction, special seizure resistance and the like, noise is reduced effectively in the working process, the roller surface of the roller is wear-resistant, the contact friction force is enhanced, the service life is prolonged, and conveying operation is facilitated.

Description

technical field [0001] The invention relates to the field of logistics equipment, in particular to a needle roller structure. Background technique [0002] The bearing capacity of the radial direction of the roller is relatively large, and the parts are highly replaceable, and are more and more used in various logistics equipment systems. Needle rollers are generally used for supporting rollers of conveying machinery. The retaining rings on both sides of the needle roller can prevent dust and foreign matter from entering the bearing roller table and prolong the service life of the bearing. When the existing needle rollers encounter working conditions such as high vacuum, strong radiation exposure, high temperature and ultra-low temperature, corrosive media, and oil poisoning media, the rollers are easily oxidized and corroded, which affects the performance and life of the product. , affecting the progress of normal conveying operations. Contents of the invention [0003]...
