Abstract
The utility model relates to the technical field of bearings and particularly relates to a reinforced cylindrical roller bearing retainer. The reinforced cylindrical roller bearing retainer provided by the utility model comprises an annular retainer body made from nylon, a plurality of window holes for placing rollers are uniformly distributed in the circumferential direction of the annular retainer body, at least two locating lock blocks facing to the centers of the window holes are arranged on two long margins of the window holes, and the locating lock blocks on the two long margins are arranged to be opposite to each other. Compared with the prior art, the reinforced cylindrical roller bearing retainer provided by the utility model improves the bearing capacity of the bearing, meanwhile, guarantees the rotation stability of the rollers and reduces the manufacturing cost.
Description
Technical field
The utility model relates to technical field of bearings, is specifically related to a kind of retainer, particularly a kind of reinforced cylinder roller bearing retainer.
Background technique
Roller bearing (cylindrical roller bearing) is the radial antifriction bearing of cylindrical roller.Roller is assemblied in the bearing through retainer, existing roller bearing retainer its to go up the fenestra that assembles roller be cylindrical strip hole, the rectangular avris wall of fenestra forms the location to roller; Such structure is provided with down, and the locating face of roller is big, and roller is prone to radially wobble in fenestra, produces fretting wear and reaches radially bearing capacity deficiency; For increasing the radially bearing capacity of roller bearing, the most directly method is to increase roller length usually, and the long stability that is unfavorable for retainer to its guiding of roller.
Summary of the invention
Deficiency to the existing technology existence; The purpose of the utility model is to provide a kind of reinforced cylinder roller bearing retainer; Be intended to improve the bearing mechanical property, improve bearing stability and bearing capacity radially, reduce the roller wearing and tearing simultaneously and improve bearing working life.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of reinforced cylinder roller bearing retainer; Comprise annular frame; Annular frame circumferentially is evenly equipped with the fenestra of some placement rollers, it is characterized in that: be equipped with on the two rectangular limits of said fenestra at least two towards the location at fenestra center lock dog, the lock dog position, location on the two rectangular limits is oppositely arranged.
Through adopting technique scheme, the location lock dog of being located in the fenestra positions roller, and the big defective of location area reduces roller and radially wobbles when reducing existing fenestra roller being positioned, and reduces wear, and improves bearing working life; Increase radially bearing capacity of bearing simultaneously.
The utility model further is set to: be provided with two pairs of location lock dogs in the described fenestra, location, two on each rectangular limit lock dog is symmetrically set in both sides, rectangular limit, and the location lock dog is partial to end, rectangular limit and is provided with, and is provided with at interval between location lock dog and the fenestra minor face.
Through adopting technique scheme, further the optimization and improvement retainer improves the reliability of positioning of location lock dog to roller to the stability of roller guiding.
The utility model further is set to: described location lock dog is the circular arc setting adaptive with the roller outer wall towards a side at fenestra center.
Through adopting technique scheme, adopt circular arc that the stability of further optimization and improvement retainer to the roller guiding is set, guarantee that the roller location is reliable, reduce the roller wearing and tearing.
The utility model further is set to: the nylon support body that described annular frame adopts nylon to process.
Through adopting technique scheme, be convenient to the manufacturing of retainer, reduce cost.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model specific embodiment retainer structural representation;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the disclosed a kind of reinforced cylinder roller bearing retainer of the utility model comprises annular frame 1, and annular frame 1 circumferentially is evenly equipped with the fenestra 10 of some placement rollers; Be equipped with at least two location lock dogs 100 on the two rectangular limits of said fenestra 10 towards fenestra 10 centers; Location lock dog 100 positions on the two rectangular limits are oppositely arranged, and location lock dog 100 is the circular arc setting adaptive with the roller outer wall towards a side at fenestra 10 centers; Be provided with down like this, each is located lock dog 100 end faces and constitutes the cavity that supplies the roller location to place.In this specific embodiment; Be provided with two pairs of location lock dogs 100 in the said fenestra 10; Location, on each rectangular limit two lock dog 100 is symmetrically set in both sides, rectangular limit, and lock dog 100 deflection ends, rectangular limit in location are provided with, and are provided with at interval between location lock dog 100 and fenestra 10 minor faces.The nylon support body that described annular frame 1 adopts nylon (PA) to process, retainer 1 also can adopt copper certainly, and materials such as steel are processed; But it is simple to adopt nylon material processing to have processing technology; Easy to process, advantage such as with low cost is so the novel preferential employing nylon of the utility model is processed.
