Abstract
The invention discloses a housing. A trisection channel is arranged inside the housing along the peripheral direction. A contact portion of the channel and a ball ring is composed of two circular arcs, and the curvature radiuses of the two circular arcs are the same. The ball ring cambered surface is tangent to the two circular arcs respectively after the channel matches with the ball ring. The invention also discloses an angular contact channel tripod constant velocity universal joint which comprises a tripod assembly, a transmission shaft and the housing. The transmission shaft is connected with the tripod assembly in a spline mode. The tripod assembly is inserted into the housing. The ball ring of the tripod assembly matches with the channel of the housing. The angular contact channel tripod constant velocity universal joint has the advantages that not only the constant velocity universal joint with reasonable force, big loading torque and strong impact resistance can transmit motions and torques steadily, reliably, flexibly and accurately.
Description
Technical field
But the present invention 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 three ball pin style constant speed 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.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention discloses a kind of angle contacting raceway groove three ball pin style constant speed universal joint and housing thereof, this universal joint bearing capacity is strong, have no abnormal sound, long service life.
The present invention 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 form, 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 three ball pin style constant speed universal joint, comprise three ball pin assemblies, transmission shaft and aforesaid housing, transmission shaft and three ball pin assembly spline joints, three ball pin assemblies insert in the housing, and the ball of three ball pin assemblies matches with the raceway groove of housing.
The invention has the beneficial effects as follows:
Angle contacting raceway groove three ball pin style constant speed universal joint can not only steadily, reliably, flexibly, accurately transmit motion and torque, and reasonable stress, and the carrying torque is large, shock-resistant.

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 form, 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 respectively O
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 respectively A point and B point; ∠ 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 is without any damage; Durability (life-span) improves more than 17%.Series of experimental results shows that the reliability of this patent product and life-span have had significantly improves.
