Abstract

The utility model discloses a novel single-piece opening type retainer of a double-line angle contact ball bearing. A retainer (56) is arranged between an outer ring (01) and an inner ring (02) of a bearing and is an annular retainer, a bag hole is arranged on the end surface at one side of the annular retainer, the end surface at the other side of the annular retainer is the bottom of the bag hole, in addition, the bottom of the bag hole is the arc-shaped bottom with the radius R identical to the radius of a bearing rolling body (04), and in addition, the outer outline of the formed bag hole forms a 10-degree included angle with the center line of the retainer. The novel single-piece opening type retainer has the advantages that the single-piece opening type retainer is used for replacing the original integral retainer, the problem of the original structure is fundamentally solved, in addition, the weight of the single-piece opening type retainer is only 0.6 time of the weight of the original integral retainer, non-ferrous metal is saved, the resin load quantity is increased, the lubricating performance is effectively improved, the bearing rotation flexibility is improved, the service life of the bearing is prolonged, the production efficiency is improved, and the manufacture cost is reduced.

Description

Novel double-row angular contact bal bearing monolithic open type retainer
Technical field
The present invention relates to a kind of field of bearings equipment therefor, more particularly, relate to a kind of novel double-row angular contact bal bearing monolithic open type retainer.
Background technique
In technical field of bearings; Double-row angular contact bal bearing uses extensively, shown in Fig. 1-4, under the existing technology; Adopt the retainer of the straight pocket of integrated type hole retainer at home as double-row angular contact bal bearing always; Integrated type retainer 46 is installed between bearing outer ring 01 and the inner ring 02, and whole retainer 46 is wrapped in outside the bearing roller steel ball 04, and is guided by the rolling element steel ball.But such integrated type retainer Heavy Weight, filling lubricating grease amount is few, and lubrication effect is bad, and the bearing limit speed is low, the high waste of retainer processing cost non-ferrous metal.
Summary of the invention
The objective of the invention is to overcome the defective that integrated type retainer under the existing technology exists, provide a kind of in light weight, practice thrift non-ferrous metal and fill out the many novel double-row angular contact bal bearing monolithic open type retainers of fat amount.
In order to achieve the above object, a kind of novel double-row angular contact bal bearing monolithic open type retainer of the present invention, the retainer integral body that is installed between bearing outer ring and the inner ring is the ring-type retainer.Wherein offer the pocket hole on the side end face of ring-type retainer, the opposite side end face is the bottom that entity is used as said pocket hole, and bottom, pocket hole is the radius R curved bottom identical with the bearing roller radius; In addition, the external frame in formation pocket hole becomes 10 ° angle with the center line of said retainer.
Because retainer is one-sided to be provided with axial R type pocket hole, thereby bearing roller is assemblied in the retainer pocket hole from monolithic one side hand-hole, and spacing by the opposite side curved bottom.The invention has the advantages that, replace original integrated type retainer, fundamentally solved the problem that original structure exists with monolithic open type retainer; And monolithic open type retainer weight only is 0.6 times of former integrated type retainer weight, has practiced thrift non-ferrous metal, and dress fat amount increases; Improve greasy property effectively, improved bearing revolution flexibility, prolonged bearing working life; Manufacturing efficiency is improved, and has reduced manufacture cost.

Embodiment
Novel double-row angular contact bal bearing monolithic open type retainer of the present invention, shown in Fig. 5-8, retainer is installed between outer ring 01 and the inner ring 02, and said retainer is a monolithic open type retainer; Said retainer is guided by external diameter; The one-sided axial R type pocket hole that is provided with of said retainer; Bearing roller 04 is assemblied in the said retainer pocket hole from the side.Wherein, angle of inclination, R type pocket hole is 10 ° on the said retainer.Specifically, retainer 56 is installed between bearing outer ring 01 and the inner ring 02, and retainer integral body is the ring-type retainer; Offer the pocket hole on one side end face of ring-type retainer, the opposite side end face is the bottom that entity is used as the pocket hole, and bottom, pocket hole is radius R and the identical curved bottom of bearing roller 04 radius; In addition, the external frame that forms said pocket hole becomes 10 ° angle with the center line of retainer.
The invention has the advantages that, replace original integrated type retainer, fundamentally solved the problem that original structure exists with monolithic open type retainer; And monolithic open type retainer weight only is 0.6 times of former integrated type retainer weight, has practiced thrift non-ferrous metal, and dress fat amount increases; Improve greasy property effectively, improved bearing revolution flexibility, prolonged bearing working life; Manufacturing efficiency is improved, and has reduced manufacture cost.
The above; Be merely the preferable structure embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
