Abstract
The invention discloses a six-row roller-type pivoting support and a processing method thereof. The six-row roller-type pivoting support comprises rollers, an outer ring, an inner ring and a median ring, and is characterized in that the rollers are arranged in six rows and are arranged between the median ring and the outer ring and between the median ring and the outer ring. In the roller-type pivoting support of the invention, the number of roller paths of the existing roller-type pivoting support is increased to 6 from 3, thus the number of rows of the rollers are increased to 6 at the left and the right from the original number 3, namely the radial rollers at the middle row of the three roller paths of the middle ring and the outer ring and at the middle row of the three roller paths of the middle ring and the inner ring are specially used for bearing radial force; and the rest four rows of rollers bear axial force and tilting moment. Compared with the existing roller-type pivoting support, the six-row roller-type pivoting support improves the bearing capacity by more than one time when the diameter of the pivoting center of the rollers and the diameter of the rollers are the same with those of the existing roller-type pivoting support. The pivoting center of the invention is suitable for workplaces bearing larger radial force and peculiarly large axial force and tilting moments.
Description
Technical field
The present invention relates to the structural design and the manufacture method thereof of many row's roller type pivoting supports.
Background technique
Require the workplace of pivoting support high bearing capacity generally to adopt three row's roller type pivoting supports now.The axial roller of two rows bears axial force and tilting moment in three row's roller type pivoting supports, the special bearing radial force of row's radial roller.Determine that the main parameter of three row's roller type pivoting support axial carrying capacities is gyration center diameter, the roller diameter of roller.Because the restriction of quenching technology for surfaces, the quenching hardness of raceway, the impossible unconfined increase of depth of hardening zone, therefore the roller diameter can not infinitely increase, improve the bearing capacity of roller type pivoting support and have only the gyration center diameter that strengthens roller, like this boundary dimension of pivoting support must strengthen many, this and heavily loaded main frame to pivoting support minor diameter, high bearing capacity require opposing.Therefore, row's number that can only promptly increase roller by the structure that changes three row's roller type pivoting supports satisfies the requirement of heavily loaded main frame to pivoting support minor diameter, high bearing capacity.
