Abstract
A kind of flange-type triangular big swing angle is without back-up ring constant-speed sliding-end universal joint.Mainly solve the problem that existing constant-speed sliding-end universal joint frictional force is large, working life is low, transmission pivot angle is little.It is characterized in that: the cross section exterior contour of described sliding-end shell is round and smooth triangle, alley is arranged at leg-of-mutton three bights of sliding-end shell, and the internal surface of alley is cylndrical surface; Described three ball pin assemblies comprise spider, bearing pin, and described bearing pin is corresponding three alleys respectively, and described end part of pin shaft sets gradually bearing inner race, needle roller, ball from the inside to the outside, are provided with the convex shoulder that restriction needle roller moves axially inside described ball.Its advantage is that sliding-end shell is triangular in shape, inner alley is not easily out of shape, structure is more reasonable, and three ball pin assemblies then eliminate back-up ring structure, spacing by himself convex shoulder, not only structure is simple, and effectively reduce friction, improve working life, the internal surface of alley is cylndrical surface in addition, transmission pivot angle can be increased, increase slippage.
Description
Technical field
The utility model relates to a kind of universal joint, is specifically related to a kind of flange-type triangular big swing angle without back-up ring constant-speed sliding-end universal joint.
Background technique
Constant velocity universal joint is the parts being mainly used in the angular velocity transmitting torque making diaxon identical in car drivetrain system.Existing constant velocity universal joint is primarily of sliding-end shell and three ball pin assemblies composition, and three ball pin assemblies are arranged in the alley of sliding-end enclosure.
But the problems such as frictional force is large, working life is low, transmission pivot angle is little that existing constant velocity universal joint exists.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of flange-type triangular big swing angle without back-up ring constant-speed sliding-end universal joint, solves the problem that existing constant-speed sliding-end universal joint frictional force is large, working life is low, transmission pivot angle is little.
The technological scheme that the utility model adopts: a kind of flange-type triangular big swing angle, without back-up ring constant-speed sliding-end universal joint, comprises sliding-end shell and three ball pin assemblies, and described three ball pin assemblies are arranged in the alley of sliding-end enclosure; The cross section exterior contour of described sliding-end shell is round and smooth triangle, and alley is arranged at leg-of-mutton three bights of sliding-end shell, and the internal surface of alley is cylndrical surface; Described three ball pin assemblies comprise spider, bearing pin, and described bearing pin is corresponding three alleys respectively, and described end part of pin shaft sets gradually bearing inner race, needle roller, ball from the inside to the outside, are provided with the convex shoulder that restriction needle roller moves axially inside described ball.
The arc surface matched with bearing pin is provided with inside described bearing inner race.
The interval of described convex shoulder is greater than needle roller axial length.
The outer wall of described sliding-end shell is provided with breach.
The beneficial effects of the utility model are: adopt above scheme, sliding-end shell is triangular in shape, and inner alley is not easily out of shape, and structure is more reasonable, three ball pin assemblies then eliminate back-up ring structure, spacing by himself convex shoulder, not only structure is simple, and effectively reduces friction, improve working life, the internal surface of alley is cylndrical surface in addition, can increase transmission pivot angle, increases slippage.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the structural representation of A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further: as shown in the figure, a kind of flange-type triangular big swing angle is without back-up ring constant-speed sliding-end universal joint, comprise sliding-end shell 1 and three ball pin assemblies 2, described three ball pin assemblies 2 are arranged in the alley 3 of sliding-end shell 1 inside; The cross section exterior contour of described sliding-end shell 1 is round and smooth triangle, and alley 3 is arranged at leg-of-mutton three bights of sliding-end shell 1, and the internal surface of alley 3 is cylndrical surface; Described three ball pin assemblies 2 comprise spider 21, bearing pin 22, described bearing pin 22 is corresponding three alleys 3 respectively, described bearing pin 22 end sets gradually bearing inner race 23, needle roller 24, ball 25 from the inside to the outside, is provided with the convex shoulder 251 that restriction needle roller 24 moves axially inside described ball 25.
Sliding-end shell 1 is triangular in shape, its alley 3 distributes more even, and not yielding, structure is more reasonable, three ball pin assemblies 2 eliminate back-up ring structure, spacing by himself convex shoulder 251, not only structure is simple, and effectively reduces friction, improve working life, the internal surface of alley 3 is cylndrical surface in addition, can increase transmission pivot angle, increases slippage.
Be provided with the arc surface matched with bearing pin 22 inside described bearing inner race 23, bearing inner race 23 is better coordinated with bearing pin 22.
The interval of described convex shoulder 251 is greater than needle roller 24 axial length, increases its slippage further.
The outer wall of described sliding-end shell 1 is provided with breach 4, can be easily installed in dismounting.
