Abstract
The utility model relates to a holder of cylindrical roller bearing design technical field, one kind concretely relates to and the rolling element rolling contact's that keeps bearing retainer. It is including keeping support body, pocket hole, hollow hole roof beam and kingpin, following circumferencial direction distribution a plurality of pocket hole on keeping the support body, being the hollow hole roof beam between the adjacent pocket hole, set up the kingpin on the hollow hole roof beam, the kingpin keeps rolling element line contact, kingpin embedding hollow hole roof beam with the institute. The utility model discloses a bearing retainer with rolling element rolling contact can make the sliding friction between rolling element and the bearing retainer become rolling friction. When the bearing is high -speed when turning round, the sliding friction of bearing rolling element and cage pin substitutes to the rolling friction between bearing rolling element and the kingpin, noise abatement not only, and rolling friction coefficient of friction is little in addition, reduces rolling element and the thermal production of cage pin sliding friction, and bearing start -up force moment reduces simultaneously, lengthens equipment bearing life.
Description
Technical field
This utility model be related to cylinder roller bearing retainer design field and in particular to a kind of with kept
The retainer that rolling element is in rolling contact.
Background technology
Cylinder roller bearing is rolling friction in operation process between rolling element and bearing internal external sleeve, and rolling friction will not
Produce heat, noise will not be produced, and be sliding friction between rolling element and retainer hole beam in operating, hole beam is integrally fixed at guarantor
Hold on frame, guiding and holding rolling element 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 bigger with the gap in retainer pocket hole, and noise is bigger, and bearing is in height
Temperature is lower to operate, if reducing clearance to reduce noise, bearing is also easy to produce and seizes phenomenon, produces after seizing, bearing temperature is immediately
Rise, when bearing transient temperature reaches 170 degree, lead to 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 retainer hole beam.
Content of the invention
In view of the defect of the rolling element of above-mentioned technology presence and retainer sliding friction, the purpose of this utility model is to provide
A kind of retainer structure that the sliding friction between rolling element and retainer can be made to be changed into rolling friction.
Technical scheme for reaching the offer of above-mentioned purpose this utility model is that a kind of bearing being in rolling contact with rolling element is protected
Hold frame, it includes keeping support body, pocket hole, hollow hole beam and needle roller；Keep several pocket holes circumferentially distributed on support body, adjacent pocket
It is hollow hole beam between hole, 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 pressing of the second column
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 cambered surface group of the first column and second column the same side
Become the pocket hole of rolling element, the circular space of both relative cambered surface composition assembling needle rollers.
Described needle roller is in close contact with rolling element, rolling return, and needle roller also turns round.
This retainer adopts combination type stretching structure, at the hole beam position of retainer by original entity pillar, is changed to
Hollow Pillar, adds a needle roller in Hollow Pillar position, allows bearing roller and the sliding friction of retainer be changed to bearing rolling
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.
This utility model beneficial effect is：Using a kind of retainer being in rolling contact with rolling element, rolling can be made
Sliding friction between body and retainer is changed into rolling friction.When bearing runs up, bearing roller and retainer
The sliding friction of pillar is replaced by the rolling friction between bearing roller and needle roller, not only reduces noise, and rolling friction
Coefficient of friction is little, reduces the generation of rolling element and cage pin sliding friction heat, and bearing staring torque reduces simultaneously, extends
Equipment bearing service life.

Specific embodiment
A kind of retainer being in rolling contact with rolling element, it includes keeping support body, pocket hole, hollow hole beam and needle roller 4；
Keep several pocket holes circumferentially distributed on support body, be hollow hole beam between adjacent pocket hole, hollow hole beam arranges needle roller 4, rolling
Pin 4 and rolling element 1 linear contact lay being kept.Hollow hole beam includes the first column 2, the 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；And 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, form 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 installing corresponding size needle roller 4, journey is in rolling contact state to rolling element 1 in the course of the work with needle roller 4, reaches and opens
Kinetic moment is little, the little effect of coefficient of rolling friction.Two pillars are through drawing molding, the circular arc energy of their both sides cambered surface
Composition rolls the pocket hole of shape, and another cambered surface can form the circular space in assembling needle roller hole.Needle roller is assembled in two
In the little cambered surface hollow pocket hole of post, these needle rollers 4 and rolling element 1 are in close contact, 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 retainer bottom hole, 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 prop up column space, will be another
One back-up ring lid, on the retainer filling rolling element 1 and needle roller 4, is pressed, is just become retainer assembly, can be installed to
In bearing inner race 6, outer ring 7, form bearing.
