Description
Technical field
The present invention relates to the retainer design field of cylinder roller bearing, be specifically related to a kind of and rolling that is that kept
The retainer of body Structure deformation.
Background technology
Cylinder roller bearing is rolling friction in operation process between rolling element and bearing internal external sleeve, and rolling friction will not
Producing heat, will not produce noise, and be sliding friction between rolling element and holding frame aperture beam in operating, Kong Liang is integrally fixed at guarantor
Hold on frame, guide and keep rolling element to roll in the correct raceway of bearing, the sliding friction energy of this rolling element and retainer
Produce amount of heat, produce sliding friction noise.Rolling element is the biggest with the gap in retainer pocket hole, and noise is the biggest, and bearing is at height
The lower operating of temperature, if reducing play to reduce noise, bearing is easily generated and seizes phenomenon, produces after seizing, and bearing temperature is immediately
Rise, when bearing transient temperature reaches 170 degree, cause bearing material to lose efficacy, affect equipment operation.Even cause fatal crass
Interruption of service.Conventional retainer technology is all that rolling element keeps sliding friction with keeping frame aperture beam.
Summary of the invention
The rolling element existed in view of above-mentioned technology and the defect of retainer sliding friction, it is an object of the invention to provide one
Plant the retainer structure that the sliding friction between rolling element and retainer can be made to become rolling friction.
The technical scheme provided for reaching the above-mentioned purpose present invention is and the retainer of rolling element Structure deformation, its bag
Include holding support body, pocket hole, hollow hole beam and needle roller；Keep along the circumferential direction being distributed several pocket holes on support body, adjacent pocket hole it
Between be hollow hole beam, hollow hole beam arranges needle roller, needle roller and institute's holding rolling element linear contact lay, needle roller embeds hollow hole beam.
Preferably hollow hole beam includes the first column, the second column and retainer ring washer；First column and the second column pressing
Between two retainer ring washers；Described needle roller is arranged between the first column and the second column.
Described needle roller length is less than hollow hole beam length.
The side of described first column and the second column is cambered surface, the first column and the cambered surface group of second column the same side
Becoming the pocket hole of rolling element, both relative cambered surface compositions assemble the circular space of needle roller.
Described needle roller is in close contact with rolling element, and rolling return, needle roller also turns round.
This retainer uses combination type stretching structure, at the Kong Liang position of retainer by original entity pillar, changes into
Hollow Pillar, adds a needle roller in Hollow Pillar position, allows bearing roller change bearing rolling into the sliding friction of retainer
Rolling friction between kinetoplast and needle roller, not only reduces noise, and after rolling friction substitutes sliding friction, reduces slip and make an uproar
Sound, reduces the generation of rolling element and cage pin sliding friction heat, and bearing staring torque reduces simultaneously, extension device bearing
Service life.
The medicine have the advantages that the retainer used with rolling element Structure deformation, rolling element and bearing can be made
Sliding friction between retainer becomes rolling friction.When bearing runs up, bearing roller and the cunning of cage pin
Dynamic friction is replaced by the rolling friction between bearing roller and needle roller, not only reduces noise, and rolling friction coefficient of friction
Little, reduce the generation of rolling element and cage pin sliding friction heat, bearing staring torque reduces simultaneously, extension device bearing
Service life.

Detailed description of the invention
With the retainer of rolling element Structure deformation, it includes keeping support body, pocket hole, hollow hole beam and needle roller 4；Keep
Along the circumferential direction it is distributed several pocket holes on support body, is hollow hole beam between adjacent pocket hole, hollow hole beam arranges needle roller 4, rolling
Pin 4 and rolling element 1 linear contact lay kept.Hollow hole beam includes the first column the 2, second column 3 and retainer ring washer 5；First
Column 2 and the second column 3 are pressed together between two retainer ring washers 5；Needle roller 4 is then arranged on the first column 2 and the second column 3
Between.Needle roller 4 length is less than hollow hole beam length.
As shown in the figure shown in 2 and Fig. 4, several first columns 2 and the second column 3 be pressed together on two retainer back-up rings 5 it
Between, forming several retainer pocket holes, it can take up rolling element 1.It is a circle between first column 2 and the second column 3
Hollow-core construction, after corresponding size needle roller 4 is installed, rolling element 1 and needle roller 4 journey Structure deformation state in the course of the work, reach to open
Kinetic moment is little, the effect that coefficient of rolling friction is little.Two pillars are through drawing molding, the circular arc energy of their both sides cambered surface
The pocket hole of composition rolling element shape, and another cambered surface can form the circular space assembling needle roller hole.Needle roller is assembled in two
In the little cambered surface hollow pocket hole of post, these needle rollers 4 are in close contact with rolling element 1, and rolling element 1 turns round, and needle roller 4 also turns round；Substitute
Sliding friction in conventional art.
Two above-mentioned retainer back-up rings 5 are to go out the hole being much combined with pillar on the end face keeping support body, one
Back-up ring does at the bottom of holding frame aperture, several first columns and the second column is pressed together on retainer back-up ring, forms several
Retainer pocket hole, can take up rolling element.After rolling element 1, needle roller 4 are encased in retainer pocket hole and a column space, will be another
One back-up ring lid, on the retainer filling rolling element 1 and needle roller 4, carries out pressing, just becomes retainer assembly, can be installed to
In bearing inner race 6, outer ring 7, form bearing.
