Abstract

The utility model discloses a tapered roller bearing retainer comprising a retainer body, wherein a plurality of pockets for mounting rollers are uniformly formed on the retainer body in a circumference direction; vertical grooves for storing lubricating grease are formed in inner walls of two sides in the pockets in contact with circumference surfaces of tapered rollers; spherical bulges are formed on inner walls of two sides in the pockets in contact with upper and lower end faces of the tapered rollers. The tapered roller bearing retainer disclosed by the utility model, through the vertical grooves which are formed in the left and right inner walls of the pockets and are used for storing lubricating grease, can improve lubricating performance of a bearing and prolong service life of the bearing; in addition, the retainer is in spherical contact with the rollers because the spherical bulges are formed on upper and lower inner walls of the pockets and the upper and lower end faces of the tapered rollers are designed as spherical grooves matched with the spherical bumps, so that friction loss is greatly reduced, the bearing can be operated flexibly, and the service life of the bearing can be prolonged.

Description

A kind of tapered roller bearing retainer
Technical field
The utility model belongs to technical field of bearings, relates in particular to a kind of tapered roller bearing retainer.
Background technique
Bearing is very extensive in technical field of engineering machinery application, bearing generally includes inner ring, outer ring and the rolling element between inside and outside circle, in order to guide and drive rolling element to roll on correct raceway, collision and friction mutually between rolling element while simultaneously preventing work, bearing comprises retainer toward contact, some for the pocket hole of rolling element is installed along being circumferentially laid with on retainer, retainer utilizes pocket hole that all rolling elements are equally spaced, is distributed on the circumference of raceway.
The retainer of existing tapered roller bearing; conventionally can carry out to the pillar between retainer pocket hole pressure slope processing (similar and chamfering), produce pressure slope face, in the situation that pillar does not have pressure surface; friction meeting between rolling element and pillar is larger, causes bearing operation dumb.The problems such as yet the grace China that in use still has rolling element in circular cone rod bearing is not in place, going slick property is poor, operating noise is larger, rolling element wearing and tearing are very fast, cause reduce the working life of tapered roller bearing and retainer thereof.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of tapered roller bearing retainer, and this retainer can improve the lubricating condition of roller, improves the flexibility of running.
In order to realize foregoing invention object, the utility model adopts technological scheme as described below:
A kind of tapered roller bearing retainer, comprise retainer body, on retainer body, be along the circumferential direction laid with some for the pocket hole of roller is installed, on the both sides inwall contacting with tapered roller circumferential surface in pocket hole, all offer for storing the longitudinal fluting of lubricant grease, on the both sides inwall contacting with the upper and lower end face of tapered roller in pocket hole, be provided with spherical surface hill.
Owing to adopting technique scheme, the utlity model has following good effect:
By offer longitudinal fluting on the inwall of left and right, pocket hole, in order to store lubricant grease, improved the greasy property of bearing, extended the working life of bearing; In addition, on the upper and lower inwall in pocket hole, spherical surface hill is set, and the upper and lower end face of tapered roller is made as to the ball recess suitable with described spherical surface hill, make between retainer and roller is sphere-contact, greatly reduce frictional loss, make the running of bearing more flexible, extended the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-retainer body; 2-pocket hole; 3-spherical surface hill; 4-groove.
Embodiment
As shown in Figure 1, a kind of tapered roller bearing retainer, comprise retainer body 1, on retainer body 1, be along the circumferential direction laid with somely for the pocket hole 2 of tapered roller is installed, on the both sides inwall contacting with tapered roller circumferential surface in pocket hole 2, all offer for storing the longitudinal fluting 4 of lubricant grease; On the both sides inwall contacting with the upper and lower end face of tapered roller in pocket hole, be provided with spherical surface hill 3, when processing tapered roller, the upper and lower end face of tapered roller is made as to the ball recess suitable with described spherical surface hill, make between retainer and roller is sphere-contact, greatly reduce frictional loss, make the running of bearing more flexible, extended the working life of bearing.
