Abstract
The invention belongs to machine component fields, 5 race bearing roller of the present invention is by a long roller, there are six four raceways that rib is formed on both sides, rib root has the root between anticracking semicircle round trip slot and 45 °~55 ° to roll stress point, additional rolling isolation locating ring, which assembles to be composed and (add to roll and locating ring is isolated) to generate one and roll, is isolated retainer, and generation, which rolls, is isolated retainer bearing.5 race bearing roller advantageous effects be bearing run at high speed operation when, (locating ring is isolated in rolling) is added between bearing roller and bearing roller, scroll positioning isolation is changed by sliding friction isolation, bearing roller produces new rolling with (roll and locating ring is isolated) and positioning trip is isolated, therefore the frictional dissipation of bearing is greatly reduced, size among roller, the service life of bearing can be extended with limit speed and working efficiency of the speed load in relation to improving bearing.
Description
Technical field
The bearing roller that the invention belongs to be used in machine component field more particularly to a kind of cylinder roller bearing.
Background technology
Cylinder roller bearing, its bearing roller are usually cylinder.Its axially loaded is usually by axis at runtime
There are one rub between planar end surface and roller on the top of oil duct for rib round trip slot oil duct hold, inner ring and outer ring plus lubricating oil
Axially loaded positioning is wiped, in this case, two easy frictional heatings of rib of bearing, friction damage causes the axis of bearing
To rapid wear.Bearing in the work that runs at high speed key wear consumption is brought by friction, mainly include rolling friction and
Sliding friction.The main portions of sliding friction, which occur, is：Contact surface, rolling element and retainer pocket between rolling element and retainer
Between contact surface, retainer and lasso boot wall between hole and between roller end face and lasso boot wall etc..It rolls
The presence of sliding friction inevitably makes bearing parts generate abrasion in bearing.If bearing steel wears no resistance, the axis of rolling
Precision will prematurely be lost due to abrasion or increase bear vibration due to running accuracy declines, service life reduction by holding.
Bearing working energy consumption can not only be improved by reducing bearing friction, and can increase substantially the use longevity of bearing
Life.The principal element of the rolling friction of bearing comes from processing quality, the roughness of the contact surface between rolling element and raceway.Bearing
Sliding friction be mostly due to retainer caused by, this is that rolling element and rib are structurally inevitable.
The sliding friction that bearing edge guard is brought is reduced and eliminated, can not only improve the limit speed of bearing, increases bearing
Service life, and greatly improve the working efficiency of bearing, reduce the maintenance and repair cost of production equipment, for production
Labour brings practical interests.The purpose of the present invention is exactly the traditional form in order to improve bearing roller from structure, so as to
It avoids because of the sliding friction that bearing roller flange belts come, so as to eliminate a series of disadvantages that sliding friction is brought to bearing.
Invention content
A series of disadvantages that retainer is isolated and brings are slided the purpose of the present invention is to solve traditional bearing, we provide
A kind of construction is novel, under dry conditions also can guarantee bearing persistently runs at high speed work, a kind of 5 race bearings rolling
Son, it is characterized on a long roller, intermediate for part of the force, four small raceways on both sides, by four unillustrated (rollings
Dynamic isolation locating ring) scroll positioning, between producing two rollers, will not rub together, axially loaded it be utilized
The axial linear rolling stress point in roller shoulder block root, the online interior outside for moving stress point are occupied certain axially loaded face, are produced
Raw axial rolling stress, solves the problems, such as that axially loaded is easy to wear.
To achieve these goals, the technical scheme is that by the way that rolling roller is made (to roll and be isolated with unillustrated
Locating ring) mode that normally rolls eliminates the sliding friction between rolling element and rolling element, and its embodiment is at one
On long roller, centre is part of the force, and four small raceways on both sides by four unillustrated (rolling isolation locating ring), roll
Isolation positioning, between producing two rollers, will not rub together, axially loaded it axial linear rolling stress is utilized
Point generates axial rolling stress, due to the angle that it employs unillustrated (raceway angle is 55 °) roller be 45 ° they it
Between have 10 ° of gap, do not generate very sharp stress and the rolling stress of a comparison fusion in two angles and apex angle
Face, by testing the stress surface of this fusion, main stress point is that a comparison is rational to roll, close not generate axial direction
A kind of roll mode of sliding friction, it is achieved thereby that axial also in rolling movement stress.5 race bearing rolling of the present invention
Sub (attached drawing 1) is to carry out rolling 5 raceway axis of isolation with the mode of unillustrated (there are four roll cage ring on both sides) rolling movement
Bearing roller.Its structure is：Bearing roller, round trip slot, positioning shoulder block, the assembling of end shoulder block are composed；Have six on bearing roller
It plays scroll positioning to a rib, and there is annular groove on the both sides of six ribs, it plays a conventional slip axially position and changes into axis
To scroll positioning.The frictional heating that slides axially is not generated by experiment, operation principle is that small angle is covered in mitre, is being rolled
Operation, the rolling point of angle is not very sharp, employs 55 ° and is rolled with 45 ° of vertex, plays between each other seldom friction
Effect.In practical applications it while the inner ring and outer ring relative motion of bearing, can keep both bearing rollers it
Between with axially loaded close to will not together with Frictional Slipping, so as to reach, by radially slide friction and slide axially friction become
As all close to rolling condition, by experiment reached non-refuelling can normal operation bearing, energy saving 14%.
5 race bearing rollers of above-mentioned construction make spherical ball rolling into suitable for cylinder roller bearing and intermediate raceway
Sub- bearing.
The beneficial effects of the present invention are bearing run at high speed operation when, four, the both sides raceway of bearing roller, which has, not to be ground
The axial positioning function of damage, it can generate with unillustrated (suspension, which rolls, is isolated locating ring) and roll buffer action again, make biography
Sliding friction operation between the retainer and rolling element of system bearing becomes for rolling-operation, greatly reduces bearing retainer and rubs
It wears consumption, improves the limit speed and working efficiency of bearing, extend the service life of bearing.

Specific embodiment
The present invention will be further described in detail below in conjunction with the accompanying drawings：
With reference to shown in attached drawing 1,5 race bearing roller of the present invention by：5 race bearing rollers 1, are determined round trip slot 1.1
Position shoulder block 1.2, end shoulder block 1.3 are composed；There are six rib, it is played and unillustrated (rolling on 5 race bearing rollers 1
Locating ring is isolated) isolation positioning is rolled, concrete application unillustrated (rolling isolation locating ring) is between 5 race bearing rollers 1
Play a part of not phase mutual friction between two 5 race bearing rollers of scroll positioning.It can keep both 5 race bearing rollers 1
Between will not Frictional Slipping together, so as to reach the function of rolling isolation retainer, 5 race bearings are isolated by sliding friction
Roller 1 becomes to roll 5 race bearing rollers 1 of isolation.
5 race bearing rollers of above-mentioned construction make spherical ball rolling into suitable for cylinder roller bearing and intermediate raceway
Sub- bearing.
The 5 race bearing rollers, can be applied to cylinder roller bearing.
