Abstract
The invention discloses a five-row pin roller type pivoting support and a processing method thereof. The five-row pin roller type pivoting support comprises pin rollers, an outer ring and an inner ring, wherein the axial planes of the inner ring and the outer ring are both provided with mounting holes. The five-row pin roller type pivoting support is characterized in that the pin rollers are arranged in five rows, and are installed between the inner ring and the outer ring. The five-row pin roller type pivoting support is improved by increasing three roller paths of a traditional pin roller pivoting support to five roller paths, thereby causing that original three rows of pin rollers is increased to five rows, wherein radial pin rollers in the middle row are specially used for bearing radial force, and the other four rows of axial pin rollers can bear the axial force and the tilting moment. Compared with a traditional three-row pin roller type pivoting support, the five-row pin roller type pivoting support can increase the bearing capacity by over one time under the same pivoting center diameter and the sane diameter of the pin roller. The pivoting support is suitable for work occasions with smaller radial force and larger axial force and tilting moment.
Description
Technical field
The present invention relates to the structural design and the processing 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.
Summary of the invention
Problem to be solved by this invention provides a kind of pivoting support of many row's roller construction, and its bearing capacity height, radial dimension is little, technology capability good.Simultaneously, its compact structure connects reliably with main frame, easily assembles, dismantles.The present invention also provides the processing method of this kind supporting.
The present invention's five row's roller type pivoting supports comprise roller, outer ring, inner ring, and the axial plane of Internal and external cycle is equipped with mounting hole, it is characterized in that: described roller is five rows altogether, is arranged between the Internal and external cycle.
Wherein, be provided with five raceways according to certain size is spaced apart on the inner ring surface of outer ring; Also offer five raceways on the outer ring surface of inner ring, its position is corresponding with the interior raceway of outer ring; Corresponding inside and outside raceway has formed complete roller path; Article five, the raceway in the centre of raceway is the side direction raceway, and the inside is placed with radial roller; The side direction raceway respectively be two plane raceways up and down, the plane raceway is parallel to each other, the inside is placed with axial roller; Adopt spacing block or integral cage to isolate between every row's roller.
When pivoting support of the present invention did not have gear ring, its processing method was:
(1) uses the roughing that common vertical lathe respectively encloses outer surface and roller surface;
(2) adopt the heat treatment lathe that the roller surface of each circle is carried out the surface hardening processing, surface hardness reaches more than the HRC55, and guarantees corresponding depth of hardening zone;
(3) use tempering furnace each circle is carried out tempering elimination quenching stress;
(4) use the fine finishing that common vertical lathe carries out each surface of circle except that roller surface;
(5) adopt numerical control drilling machine that each circle mounting hole is carried out Drilling Operations;
(6) use numerical control vertical lathe and carry out the fine finishing of raceway.
When pivoting support of the present invention had gear ring, its processing method was:
(1) uses the roughing that common vertical lathe respectively encloses outer surface and roller surface;
(2) adopt the heat treatment lathe that the roller surface of each circle is carried out the surface hardening processing, surface hardness reaches more than the HRC55, and guarantees corresponding depth of hardening zone;
(3) use tempering furnace each circle is carried out tempering elimination quenching stress;
(4) use the fine finishing that common vertical lathe carries out each surface of circle except that roller surface;
(5) adopt numerical control tooth working machine tool to carry out gear ring processing;
(6) adopt numerical control drilling machine that each circle mounting hole is carried out Drilling Operations;
(7) use numerical control vertical lathe and carry out the fine finishing of raceway.
Roller type pivoting support of the present invention is that the raceway in the existing roller type pivoting support is increased to five by three, thereby make roller row number increase to five rows up and down by three original rows: the special bearing radial force of row's radial roller in the middle of it, the axial roller of all the other four rows bears axial force and tilting moment.The present invention and existing three row's roller type pivoting supports are compared, and bearing capacity is more than doubled under the identical situation of roller gyration center diameter, roller diameter.Simultaneously, its compact structure can satisfy the requirement of heavily loaded main frame to pivoting support minor diameter, high bearing capacity, and meets the product design concept of lightweight, economized.Pivoting support of the present invention is applicable to axial force and the king-sized workplace of tilting moment that the radial force of bearing is very little, bear.
