Abstract
The invention belongs to the field of mechanical parts, and especially relates to a rolling isolation holder used on a bearing. The rolling isolation holder is formed by assembling an inner auxiliary ring, an inner auxiliary ring, double gear isolation rollers, single gear isolation rollers, inner supporting rollers and outer supporting rollers. The rolling isolation holder has the following advantages: a rolling element rolls synchronous with and relative to the double gear isolation rollers and the single gear isolation rollers of the holder with friction during the high speed running work of the bearing, and the inner auxiliary rings and the outer auxiliary rings of the holder roll relative to each other with the rolling of the double gear isolation rollers and the single gear isolation rollers, so sliding friction between the holder and the rolling element in a traditional bearing becomes rolling friction, thereby the friction loss of the bearing is greatly reduced, the limit rotating speed and the work efficiency of the bearing are improved, and the service life of the bearing is prolonged.
Description
Technical field
The invention belongs to mechanical parts field, particularly relate to the roller holder that a kind of bearing uses.
Background technique
Rolling bearing is generally made up of inner ring, outer ring, rolling element and retainer.The key wear consumption of bearing in the work of running up is brought by friction, and it mainly comprises rolling friction and sliding friction.The main portions of sliding friction occurs is: the surface of contact between rolling element and raceway, surface of contact, retainer and lasso between rolling element and retainer pocket hole guide between rib and roller end face and lasso guide between rib.In rolling bearing, the existence of sliding friction inevitably makes bearing parts produce wearing and tearing.If wearing no resistance of Bearing Steel, rolling bearing just can be lost precision prematurely or make bear vibration increase, service life reduction because running accuracy declines because of wearing and tearing.
Reduce pivot friction not only can improve bearing working energy consumption, and can increase substantially bearing working life.The principal element of the rolling friction of bearing from quality of processing, the roughness of the surface of contact between rolling element and raceway.The sliding friction major part of bearing causes because of retainer, and this is that rolling element and retainer are inevitably textural.
Reduce and eliminate the sliding friction that retainer brings, not only can improve the limit speed of bearing, increase the working life of bearing, and improve the working efficiency of bearing greatly, reduce the maintenance and repair cost of manufacturing mechanism, for productive labor brings practical interests.Object of the present invention is exactly the traditional retainer form in order to improve bearing from structure, thus avoids because the sliding friction that brings of retainer, thus eliminates a series of disadvantages that sliding friction brings to bearing.
Summary of the invention
The object of the invention is a series of disadvantages brought to solve traditional bearing retainer form, providing a kind of and constructing novelty, also can ensure that bearing continues the rolling isolation retainer of the work of running up under dry conditions.
To achieve these goals, technological scheme of the present invention is by making rolling element mode of rolling relative to retainer eliminate sliding friction between rolling element and retainer.Rolling isolation retainer of the present invention is formed from roller, inner support roller and outer support roller Assembly by interior auxiliary circle, outer auxiliary circle, folk art term isolation roller, single block; Two block is provided with end shoulder block from roller two ends, and single block is at one end provided with location shoulder block near the position of end from roller; Inner support roller, outer support roller and two single blocks are from roller composition support rollers group, two single blocks are from roller reversed arrangement side by side, inner support roller assigns into single block between roller and bearing inner race raceway, and outer support roller assigns into single block between roller and bearing outer ring ball track; Two block is evenly distributed by quantitative proportion from roller and back-up roller subgroup, and two block is in same center circle from roller, single block from the axle center of roller and bearing roller; Two block from roller and single block from the both sides of roller respectively by auxiliary circle in and an outer auxiliary circle axially locating, interior auxiliary circle and the outer auxiliary circle of the same side are in same radial direction, two block is stuck in from roller and single block from the axle head of roller between interior auxiliary circle and outer auxiliary circle, the end shoulder block of folk art term isolation roller is stuck in the outside of interior auxiliary circle and outer auxiliary circle, and single block is stuck in the inner side of interior auxiliary circle and outer auxiliary circle from the location shoulder block of roller.
Described interior auxiliary circle and outer auxiliary circle are the axle collars with certain thickness and height, auxiliary circle exradius=bearing inner race radius+ball bearing radius wherein-folk art term isolation radius of roller, outer auxiliary circle inner circle radius=bearing inner race radius+ball bearing radius+folk art term isolation radius of roller, ensure that the two block of retainer rolls in same center circle position from roller and single block from roller and bearing roller.
Described folk art term isolation roller two ends are provided with shoulder block, open loop journey groove on shoulder block inside bottom axial plane, and inside shoulder block, hypotenuse and axial plane are 100 ° to 105 °, decrease and friction between interior auxiliary circle and outer auxiliary circle side.
Described single block is at one end provided with shoulder block near the position of end from roller, open loop journey groove on shoulder block two side bottom axial plane, and shoulder block both sides hypotenuse and axial plane are 100 ° to 105 °, decreases and friction between interior auxiliary circle, outer auxiliary circle side and rolling element.
Described inner support roller and outer support roller are cylindric, and structure size is identical.
The rolling isolation retainer of above-mentioned structure, is applicable to roller bearing and ball roller bearing.
Beneficial effect of the present invention be bearing run up operation time, the folk art term of rolling element and retainer isolate roller and single block between roller with the locking phase that rubs to rolling, the interior auxiliary circle of retainer and outer auxiliary circle also roll from roller and single block from the rolling of roller is relative with two block, the sliding friction in traditional bearing between retainer and rolling element is made to have become rolling friction, greatly reduce bearing friction loss, improve limit speed and the working efficiency of bearing, extend the working life of bearing.
