Abstract

The invention discloses a precise movable middle check ring which comprises a check ring body. A matched hole is formed in the center of the check ring body, and arc-shaped taper faces are arranged onthe two side end face of the check ring body. The invention further provides molding equipment which comprises a base, a fixed clamp, a clamping mechanism, an air cylinder set, a high-strength fixingplate, a motor and a milling knife, the fixed clamp is arranged on the base and is provided with the clamping mechanism, the air cylinder set is formed by a plurality of air cylinders arranged on theperipheral side of the fixed clamp, a stretchable rods of the air cylinders are connected with the high-strength fixing plate, an output shaft of the motor is fixedly connected with the milling knife, the lower end face of the milling knife is coincident with the arc-shaped taper face of the check ring body in shape. The precise movable middle check ring changes the contact condition of a middlechecking part and the roller end face is changed, the stability of a roller in the bearing running process is improved, the service life of the bearing is prolonged, the arc-shaped taper face is quickly molded through molding equipment, and the production efficiency is high.

Description

【Technical field】 [0001] The invention relates to the technical field of bearings, in particular to a precision movable retaining ring and its forming equipment. 【Background technique】 [0002] The moving retaining ring plays the role of guiding the rolling elements and the cage in the self-aligning roller bearing. During the loaded operation of the self-aligning roller bearing, the rollers are automatically adjusted so that the load acts on the middle of the rollers and is in contact with the external load. The direction is the same; but due to the influence of the bearing precision, the rollers will slide to different degrees when they adjust themselves, and the friction generated by the sliding will directly affect the service life of the bearing. In order to improve the stability of the rollers in the running process of the bearing, it is necessary to propose a precision movable retaining ring and its forming equipment. 【Content of invention】 [0003] The purpose of t...
