Abstract
The utility model discloses a triple-column groove casing. The utility model also discloses an angular contact channel tripod constant velocity universal joint comprises a tripod assembly, a transmission shaft and the triple-column groove casing; the transmission shaft is connected with the tripod assembly in a spline mode; the tripod assembly is instead into the triple-column groove casing; a ball ring of the tripod is matched with the channel of the triple-column groove casing. The angular contact channel tripod constant velocity universal joint has the advantages of being capable of stably, reliably, flexibly and accurately transferring movement and torque and being reasonable in force bearing, large in torque bearing and impaction resistant.
Description
Technical field
But the utility model relates to a kind of universal joint of axial stretching, when transmission shaft, driven shaft have angular displacement and axial displacement simultaneously, can transmit the angle contacting raceway groove tripod constant-velocity universal joint of motion and torque; Simultaneously, also relate to the housing that universal joint adopts.
Background technique
The three ball pin style universal joint of conventional construction is general circular arc along circumference trisection raceway groove and ball contacting point and since with ball be Spielpassung, for making revolution and axial stretching flexible, the gap is relatively large, causes abnormal sound during work, bearing capacity reduces, and working life is shorter.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model discloses a kind of angle contacting raceway groove tripod constant-velocity universal joint and housing thereof, this universal joint bearing capacity is strong, have no abnormal sound, long service life.
The utility model has adopted following technological scheme:
Housing, the circumferential direction inside direction is provided with the trisection raceway groove, it is characterized in that, and raceway groove and ball contacting point are that two sections circular arcs are formed, and the radius of curvature of two sections circular arcs is identical; Raceway groove is with after ball cooperates, and ball cambered surface and this two sections circular arcs are tangent respectively.As preferably, the wrapping angle of ball and raceway groove is 10 ~ 14 °.Further, wrapping angle is 12 °.
Angle contacting raceway groove tripod constant-velocity universal joint, comprise three ball pin assemblies, transmission shaft and aforesaid housing, transmission shaft is connected with three ball pin assembly splines, and three ball pin assemblies insert in the housing, and the ball of three ball pin assemblies matches with the raceway groove of housing.
The beneficial effects of the utility model are:
Angle contacting raceway groove tripod constant-velocity universal joint can not only steadily, reliably, flexibly, accurately transmit motion and torque, and stressed reasonable, and the carrying torque is big, shock-resistant.

Number in the figure: 1-three ball pin assemblies, 2-transmission shaft, 3-housing, 4-spider, 5-ball, 6-bearing pin, 7-needle roller, 8-circlip, 9-back-up ring, 10-jump ring, 11-raceway groove, 12-raceway groove and ball contacting point, 13-driven shaft.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, angle contacting raceway groove tripod constant-velocity universal joint comprises three ball pin assemblies 1, transmission shaft 2 and housing 3;
Three ball pin assemblies comprise spider 4 and ball 5, are evenly equipped with three bearing pins 6 on the spider; Ball is the outer spherical surface of symmetry, and the ball internal diameter is assemblied on the bearing pin by completely adorning needle roller 7, and fixing by back-up ring 9 and jump ring 10, and ball can rotate around bearing pin; Three ball pin assemblies are connected with transmission shaft by spline, and are locked on the transmission shaft by circlip 8; Three ball pin assemblies insert in the housing, and the ball of three ball pin assemblies matches with the raceway groove of housing.Three ball journal assemblies are existing current techique.
As shown in Figure 2, housing, the circumferential direction inside direction is provided with trisection raceway groove 11, and raceway groove and ball contacting point 12 are that two sections circular arcs are formed, and the radius of curvature of two sections circular arcs is identical; Raceway groove is with after ball cooperates, and ball cambered surface and this two sections circular arcs are tangent respectively.
As shown in Figure 3, the centre of curvature of two sections circular arcs is labeled as O respectively
1, O
2, the outer spherical surface centre of curvature of ball is labeled as O, and ball and two sections circular arcs are tangential on A point and B point respectively; ∠ AOC or ∠ BOC are the wrapping angle of ball and raceway groove, and described wrapping angle is 12 °.
This product loads moment of torsion and has improved 13.3% than industry standard through test, and frequency accelerates 50%, and product does not have any damage; Durability (life-span) improves more than 17%.A series of test result show that this patent reliability of products and life-span have had significantly improves.
Claims (4)
