Abstract
The utility model provides a novel four-point contact ball bearing which comprises an outer ring, an inner ring, a steel ball and a holding rack. The contact angle of the bearing is increased to 40 degrees so as to improve the axial bearing capacity of the bearing; the holding rack of the bearing adopts an integrated self-locking holding rack; and the steel ball can be effectively locked through an inner lock mouth of the holding rack, so that the phenomena that the holding rack is deformed due to chisel mark and the ball falls due to uneven hold depth are effectively avoided. The bearing is suitable for a gearbox of a subway/light track or other similar special conditions.
Description
Technical field
The utility model belongs to technical field of bearings, and particularly a kind of four-point contact ball is applied to the subway light rail gear-box.
Background technique
Four-point contact ball contact angle originally is 35 degree, form for national Specification, this airframe bearing is applicable to common bearing under the situation that radially reaches axial joint load effect, and the subway light rail gear-box requires bearing to carry out high speed rotating under the pure axial load bearing, original structure bearing axial carrying capacity and reliability in the case is lower, is not suitable for this operating mode.
Summary of the invention
The purpose of this utility model provides a kind of novel four-point contact ball, improves its axial bearing capacity, to satisfy the applying working condition of subway light rail gear-box with bearing.
The technical solution of the utility model is: a kind of new-type four-point contact ball, comprise outer ring 1, inner ring 2, steel ball 3 and retainer 4, retainer 4 is an integral type self-locking retainer, the interior fore shaft of retainer 4 pins steel ball 3, and this bearing contact angle degree is made as 40 degree, improves the axial carrying capacity of bearing.
The beneficial effects of the utility model are: this bearing contact angle degree is increased to 40 degree, has increased the axial bearing capacity of bearing, is applicable to subway light rail gear-box and other similar special circumstances; This retainer is an integral type self-locking retainer, and the interior fore shaft by retainer can effectively pin steel ball, prevent from effectively to cut a hole seal cause the retainer distortion and occur because of hold depth is uneven the ball phenomenon.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 outer ring, 2 inner rings, 3 steel balls, 4 retainers.
Embodiment
As shown in Figure 1, the utility model comprises outer ring 1, inner ring 2, steel ball 3 and retainer 4, retainer 4 is an integral type self-locking retainer, and the interior fore shaft by retainer can effectively pin steel ball 3, prevent from effectively to cut a hole seal cause the retainer distortion and occur because of hold depth is uneven the ball phenomenon.The bearing contact angle degree increases to 40 degree by 35 traditional degree, has increased the axial bearing capacity of bearing, satisfies the applying working condition of subway light rail gear-box with bearing.
