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 full speed thrust bearing, to be composed of inner ring, outer ring, bearing roller and rolling isolation locating ring assembling.The beneficial effects of the present invention are bearing run at high speed operation when, it is isolated between bearing roller and bearing roller by sliding friction and changes into scroll positioning isolation, locating ring is isolated with rolling and produces new rolling isolation positioning trip for bearing roller, axially loaded has traditional thrusting plate bearing to change on raceway, the principle positioned using nature line axial rotary pure rolling, thus the radial and axial frictional dissipation of bearing is greatly reduced, the service load of bearing is improved, extends the service life of bearing.On the roller of bearing, there are multiple axial pure rolling stress points in centre, and the axial carrying for having bearing larger can be big, and both sides cannot bear especially big high speed centrifugation power, be accordingly used in full speed thrust bearing.
Description
Technical field
The roller holder that the invention belongs to be used in machine component field more particularly to a kind of thrust bearing.
Background technology
Thrust bearing is generally made of roller holder thrusting plate.Key wear of the bearing in the work that runs at high speed disappears
Consumption is brought by friction, mainly includes rolling friction and sliding friction.The main portions of sliding friction, which occur, is：Rolling element
Contact surface between raceway, sliding friction occurs is that contact surface, thrust bearing between rolling element and retainer pocket hole has
Roller type ball-type, their disadvantage are on thrusting plate raceway, have 2 points or more sliding frictions are generated under the action of centrifugal force, are begun
There is sliding friction etc. eventually.The presence of sliding friction inevitably makes bearing parts generate abrasion in rolling bearing.If axis
Wearing no resistance for steel is held, rolling bearing will prematurely lose precision due to abrasion or make bear vibration due to running accuracy declines
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.Axis
Caused by the sliding friction held is mostly due to retainer, 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 is exactly traditional retainer form in order to improve thrust bearing from structure,
So as to avoid because of the sliding friction that retainer is brought, so as to eliminate a series of disadvantages that sliding friction is brought to thrust bearing.
Invention content
The purpose of the present invention is to solve a series of disadvantages that traditional thrust bearing retainer form is brought, and provide one kind
Construction is novel, also can guarantee thrust bearing under dry conditions persistently runs at high speed the rolling isolation retainer of work.
To achieve these goals, the technical scheme is that passing through, on the outer ring and inner ring of bearing, there are one it
Axial natural rotation line, on rotational line, allows roller to be rotated above, and the several rotation stress surfaces of multi-processing just can reach larger
Axial bearing capacity, in this case, in axial-rotation, axially loaded eliminate axial-rotation sliding friction, so as to reach
Axially loaded is in pure rolling rotation, here it is its operation principles.Rolling element is allowed to carry out rolling with inner ring and outer ring to reach radially
Stress, axially loaded also pure rolling reach axial-rotation pure rolling, so as to solve can radial force also can axially loaded
It ensure that the radial and axial of bearing is rolling normal rotation, isolation retainer rolled at full speed so as to reach the chain type of new construction
Thrust bearing.It is to carry out axial direction with the mode of rolling movement that chain type of the present invention, which rolls isolation retainer bearing (attached drawing 1),
Roll isolation.Its structure is：Assembling is composed as shown in Figure 1 for inner ring, outer ring, roller, locating ring；On bearing roller both sides
There are four raceway, it plays scroll positioning, rolls and plays two bearing rollers of scroll positioning between isolation locating ring and bearing roller
Between not phase mutual friction effect.While inner ring and outer ring relative motion, bearing roller can be kept between the two will not
Frictional Slipping together has several axial rolling stress surfaces on the main stress face among roller, so as to reach chain type
The function of isolation retainer full speed thrust bearing is rolled, the rolling of pure rolling isolation bearing is become by sliding friction isolation bearing roller
Son by the form for axially having thrusting plate bearing format change to be inner ring and outer ring pure rolling axial thrust, eliminates cylindrical roller
Or 2 points or more of slip of ball, rolling bearing and the format of being integrally formed of thrust bearing can be made, so as to reach axial direction
The thrust bearing of pure rolling.
The chain type of above-mentioned construction rolls isolation full speed bearing, suitable for being applied in combination for bearing and thrust bearing.
The beneficial effects of the present invention are during thrust bearing runs, bearing roller 1 is isolated locating ring 2 with rolling and is generated
Buffer action is rolled, sliding friction between the retainer of traditional bearing and rolling element is run and becomes for rolling-operation, significantly
Bearing retainer frictional dissipation is reduced, the loss of main stress rollers wear can reach by experiment bearing roller and be not added with
Oil can normal operation bearing, energy saving 14%.

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, chain type of the present invention roll isolation retainer full speed thrust 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, outer ring 4 fills
With being composed；There are four raceway, it plays scroll positioning on bearing roller 1 both sides, roll isolation locating ring 2 and bearing roller 1 it
Between play a part of not phase mutual friction between two bearing rollers of scroll positioning.While 4 relative motion of inner ring 3 and outer ring,
Can keep bearing roller 1 between the two will not Frictional Slipping together, bearing roller main stress raceway and outer ring and inner ring, he
Axial natural rotation line on, subject the rotation of axial pure rolling, axial pressure improved by multilayer, realizing can
Axially loaded, also can radial force, so as to reached chain type roll isolation retainer full speed thrust bearing function, rubbed by slip
Isolation bearing roller 1 is wiped to become to roll isolation bearing roller 1.
The chain type of above-mentioned construction rolls isolation retainer full speed thrust bearing, and the combination suitable for bearing and thrust bearing makes
With.
The chain type of above-mentioned construction rolls isolation retainer full speed thrust bearing, suitable for original big load bearing.
Bearing roller 1 of the present invention is isolated locating ring 2 with rolling, is installed in the following manner, pacifies at roller both ends
Dress rolls isolation locating ring 2.Inner ring maximum outside diameter is approximately equal to the 3/4 of the minimum diameter of outer ring, and inner ring is put into inner ring in outer ring
With the gap of outer ring, the roller installed is put in and then is evenly distributed, can be completed installing locating ring.
