Cylindrical roller bearing ring, cylindrical roller bearing, and planetary gear bearing unit

By forming positioning and non-positioning edges on both axial sides of the cylindrical roller bearing ring, and forming a bevel chamfer or prismatic chamfer at the positioning edge, the cylindrical roller bearing assembly process is solved. The difficulty in identifying positioning and non-positioning edges has achieved higher assembly accuracy and production efficiency.

AI Technical Summary

Technical Problem

During the assembly and maintenance of cylindrical roller bearings, it is difficult to effectively identify and distinguish between positioning and non-positioning edges, resulting in possible misoperation and assembly errors.

Method used

The positioning and non-positioning edges are formed on both sides of the axial direction of the bearing ring, and a conventional chamfer identification structure different from the non-positioning edges are formed at the shoulder position of the positioning edges, forming a bevel chamfer or prism. Chamfer to enhance visual visibility.

Benefits of technology

Through the use of the identification structure, the visual difference between the positioning and non-positioning edges is significantly enhanced, the assembly error operation is avoided, the bearing ring identification process is simplified, and the production cost is reduced.

Abstract

A single-row or double-row cylindrical roller bearing ring (11) comprises a positioning flange (11A) and a non-positioning flange (11B) which are respectively formed on two axial sides of the single-row or double-row cylindrical roller bearing ring (11). Wherein the positioning flange (11A) is provided with an identification structure (15) at a position adjacent to the end face of the bearing ring, and the identification structure is different from a conventional chamfer (14) formed by the non-positioning flange (11B) at a corresponding position. On the basis of the bearing ring (11), the utility model further provides a planetary gear bearing unit which comprises a planetary gear (20) and a cylindrical roller bearing (10) assembled in an inner hole (21) of the planetary gear (20). The cylindrical roller bearing (10) comprises at least two bearing inner rings (11) and an inner hole (21) serving as a raceway of a bearing outer ring. The planetary gear (20) also has a shoulder (23) formed in its inner bore (21). The at least two bearing inner rings (11) are arranged opposite each other in the axial position of the corresponding shoulder (23) with a positioning flange (11A) adjacent to the inner rings (11).
