Cylindrical roller bearing with inner ring punched into two columns

Abstract

A cylindrical roller bearing with an inner ring punched into two columns comprises an outer ring, the inner ring, a cylindrical rolling body, a sealing ring assembly and a connecting ring. An annular inner ring punched portion is arranged on the inner ring; an inner V-shaped annular notch and an outer V-shaped annular notch which are opposite to each other are formed in the inner end and the outer end of the inner ring punched portion respectively, and are connected into the whole inner ring through the inner ring punched portion. After machining of the whole inner ring is all completed, the inner ring is divided into two independent inner ring bodies in a mechanical mode. When a finished product is assembled, the two independent inner ring bodies are mounted along irregular teeth at end face cracking portions of the inner ring bodies in a joint close mode. Relative rotating and displacement of the two inner ring bodies can be prevented in the using and loading process, and the cylindrical roller bearing with the inner ring punched into two columns is formed. According to the cylindrical roller bearing, the end faces of the two inner ring bodies are mounted in an irregular tooth combination mode, so that the relative rotating and displacement of the two inner ring bodies are avoided in the using and loading process, temperature rise caused by mutual friction of the two end faces of the two inner ring bodies during contact is lowered, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention belongs to the technical field of bearing manufacture, and in particular relates to a double-row cylindrical roller bearing with inner ring punching which prevents relative rotation and displacement of two inner rings. Background technique [0002] For double-row cylindrical roller bearings with traditional structure, the inner ring is mostly composed of two independent rings due to consideration of the actual situation during assembly during processing. In the actual production and application process, the two independent inner rings will cause relative rotation or displacement because the end faces are in contact with two planes, which will loosen the inner ring components that should be tightly connected. The wear of the two inner rings reduces the service life of the bearing and affects the entire production system. Moreover, frequent replacement of bearings will also increase the production cost. The structure of the inner ring of t...
