Abstract
The roller holder that the invention belongs to be used in machine component field more particularly to a kind of bearing.Chain type of the present invention, which rolls isolation retainer high-speed bearing, to be composed of inner ring, outer ring, bearing roller and rolling isolation locating ring assembly.The beneficial effects of the present invention are bearing run at high speed operation when, it is isolated by sliding friction between bearing roller and bearing roller and changes into scroll positioning isolation, locating ring is isolated with rolling and produces new rolling isolation positioning trip for bearing roller, thus the frictional dissipation of bearing is greatly reduced, the limit speed and working efficiency for improving bearing, extend the service life of bearing.Operation suitable for various speed.
Description
Technical field
The roller holder that the invention belongs to be used in machine component field more particularly to a kind of bearing.
Background technology
Rolling bearing is generally made of inner ring, outer ring, rolling element and retainer.Bearing is main in the work that runs at high speed
Attrition is brought by friction, includes mainly rolling friction and sliding friction.The main portions of sliding friction, which occur, is：
Contact surface, retainer between contact surface, rolling element between rolling element and raceway and retainer pocket hole and lasso boot wall
Between and roller end face and lasso boot wall between etc..The presence of sliding friction inevitably makes bearing in rolling bearing
Part generates abrasion.If bearing steel wears no resistance, rolling bearing will prematurely lose precision because of abrasion or because of rotation
Accuracy decline and make bear vibration increase, service life reduction.
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 retainer are structurally inevitable.
The sliding friction that retainer is brought is reduced and eliminated, the limit speed of bearing can be not only improved, increase bearing
Service life, and the working efficiency of bearing is greatly improved, the maintenance and repair cost of production equipment is reduced, to produce labor
It is dynamic to bring practical interests.The purpose of the present invention be exactly in order to from structure improve bearing traditional retainer form, to
It avoids because of the sliding friction that retainer is brought, to eliminate a series of disadvantages that sliding friction is brought to bearing.
Invention content
The purpose of the present invention is to solve a series of disadvantages that traditional bearing retainer form is brought, and provide a kind of construction
It is novel, also can guarantee that bearing persistently runs at high speed the rolling isolation retainer of work under dry conditions.
To achieve the goals above, the technical scheme is that by way of making rolling element and retainer relative rolling
To eliminate the sliding friction between rolling element and retainer.Chain type of the present invention rolls isolation retainer bearing (attached drawing 1)
It is to be carried out rolling isolation with the mode of rolling movement.Its structure is：Bearing roller, round trip slot, positioning shoulder block, end shoulder block,
Isolation locating ring, inner ring are rolled, outer ring assembly is composed；There are four rib, it plays scroll positioning on bearing roller, rolls
Play a part of not phase mutual friction between two bearing rollers of scroll positioning between isolation locating ring and bearing roller.In inner ring and
While the relative motion of outer ring, can keep bearing roller between the two will not Frictional Slipping together, to reach chain type
The function of rolling isolation retainer bearing is become to roll isolation bearing roller by sliding friction isolation bearing roller.This high speed
Bearing spy is suitable for the active force fan blade of aircraft, and under tens of thousands of turns of rotating speed, it is small not have to oiling resistance.
The chain type of above-mentioned construction rolls isolation retainer, is suitable for cylinder roller bearing and ball roller bearing.
The beneficial effects of the present invention are bearing run at high speed operation when, bearing roller 1 with roll be isolated locating ring 2 generation
Buffer action is rolled, so that the sliding friction between the retainer of traditional bearing and rolling element is run and becomes for rolling-operation, significantly
Reduce bearing retainer frictional dissipation, by experiment reached non-refuelling can normal operation bearing, energy saving 14%.

In attached drawing：Bearing roller 1, positioning shoulder block 1.2, end shoulder block 1.3, rolls isolation locating ring 2, is interior round trip slot 1.1
Circle 3, outer ring 4.
Specific implementation mode
The present invention will be further described in detail below in conjunction with the accompanying drawings：
In conjunction with shown in attached drawing, chain type of the present invention roll isolation retainer high-speed bearing by：Bearing roller 1, round trip
Slot 1.1, positioning shoulder block 1.2, end shoulder block 1.3, roll isolation locating ring 2, inner ring 3, and the assembly of outer ring 4 is composed；Bearing rolls
There are four rib, it plays scroll positioning on son 1, rolls and plays scroll positioning two between isolation locating ring 2 and bearing roller 1
The not effect of phase mutual friction between bearing roller.While 4 relative motion of inner ring 3 and outer ring, 1 liang of bearing roller can be kept
Between person will not Frictional Slipping together, to reach the function that chain type rolls isolation retainer bearing, by sliding friction every
Off-axis bearing roller 1 becomes to roll isolation bearing roller 1.
The chain type of above-mentioned construction rolls isolation retainer, is suitable for cylinder roller bearing and ball roller bearing.
Fig. 1 bearings, since all stress points are all in rolling movement, both ends raceway and the rolling of bearing roller 1
Sub- diameter is equal and is that a knife processes and loading onto shoulder block 1.2 and shoulder block 1.3, eliminates the error that machining accuracy is brought, no
Rotation lock is generated, various speed are applicable to.
Chain type of the present invention rolls isolation retainer high-speed bearing Fig. 1, installs in the following manner, does not fill first all
Shoulder block after being assembled according to Fig. 1, is heating all shoulder blocks, is being installed by close-fitting.
