Abstract
The invention discloses an inner ball cage of a constant speed driving shaft. The inner ball cage comprises a bell-shaped casing and a three-fork bearing, wherein the bell-shaped casing sleeves the three-fork bearing; the three-fork bearing comprises a rotating bearing; the bell-shaped casing is provided with a sliding groove for the rotating bearing to slide in; an unfolding angle ring sleeves an outer ring of the rotating bearing; the unfolding angle ring is in clearance fit with the outer ring of the rotating bearing; the cross section of an inner hole of the unfolding angle ring is in a trapezoidal shape; a large diameter end of the inner hole of the unfolding angle ring faces the axis of the three-fork bearing; the outer surface of the unfolding angle ring is a curved surface; the circular arc transition is formed at the corner position of the outer surface and the end surface of the unfolding angle ring. According to the inner ball cage of the constant speed driving shaft, the unfolding angle ring sleeves the outer ring of the rotating bearing and accordingly the rotating angle of the ball cage is increased, meanwhile the strength and the abrasion resistance of the three-fork bearing are improved, and the service life is extended.
Description
Technical field
The present invention relates to vehicle constant velocity driving shaft, particularly a kind of constant velocity driving shaft internal spherical cage.
Background technique
Ball cage be also called " constant velocity universal joint " be car drivetrain system in vitals, its effect is that the power of motor is delivered to wheel from speed changer, drive vehicle traveling.Internal spherical cage comprises triadius type and six bead, and the constant velocity driving shaft internal spherical cage used in the market comprises bell shell and is set in the trident bearing in bell shell, by trident bearing slippage or rotation in the chute of bell shell, realizes the gearing of internal spherical cage; The constant velocity driving shaft internal spherical cage of transmission is comparatively large or corner is comparatively large at rotating speed, and trident bearing and bell shell collide, and easily cause damage, and change cumbersome, and its cost is higher; Moved in chute by rotary bearing, the angle that ball cage rotates is less simultaneously.
Summary of the invention
The present invention is to overcome defect in above-mentioned prior art, provides a kind of intensity large, wear-resistant, the constant velocity driving shaft internal spherical cage that corner is large.
For achieving the above object, the invention provides a kind of constant velocity driving shaft internal spherical cage, comprise bell shell and be set in the trident bearing in bell shell, described trident shaft is contracted and is drawn together rotary bearing, described bell shell is provided with the chute for rotary bearing slippage, the outer ring of described rotary bearing is arranged with exhibition square ring, the outer ring Spielpassung of described exhibition square ring and rotary bearing, the inner hole section of described exhibition square ring is trapezoidal, the larger diameter end of the endoporus of described exhibition square ring is towards the axle center of trident bearing, and the outer surface of described exhibition square ring is cambered surface.
Be set to further: the outer surface of described exhibition square ring and corner's arc transition of end face.
Be set to further: described exhibition square ring is formed from steel.
Compared with prior art, the present invention is by the sheathed exhibition square ring in the outer ring of the rotary bearing of trident bearing, thus ball cage in the course of the work, avoid the direct collision of rotary bearing and bell shell, what collide is exhibition square ring, thus serve the object of protection trident bearing, add intensity and the wear resistance of trident bearing; The inner hole section simultaneously opening up square ring is trapezoidal, rotary bearing moves in exhibition square ring, and exhibition square ring moves in chute, effectively adds the corner of ball cage, different exhibition square rings can be changed as required thus the bell shell of adaptation different size and type simultaneously, improve the adaptability of trident bearing.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of constant velocity driving shaft internal spherical cage of the present invention;
Fig. 2 is the perspective view of trident bearing in Fig. 1;
Fig. 3 is the plan view of trident bearing.
Mark the following drawings mark thereon by reference to the accompanying drawings:
1-bell shell; 11-chute; 2-trident bearing; 21-ramp bearings; 3-opens up square ring.
Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
A kind of constant velocity driving shaft internal spherical cage of the present invention as shown in Figure 1, Figure 2 and Figure 3, the trident bearing 2 comprising bell shell 1 and be set in bell shell 1, trident bearing 2 comprises three rotary bearings 21, is provided with three chutes, 11, three rotary bearings 21 and is contained in respective chute 11 in bell shell 1, the outer ring of three rotary bearings 21 is all arranged with exhibition square ring 3, by opening up the setting of square ring 3, improve intensity and the wear resistance of trident bearing 2, effectively avoid the direct collision of rotary bearing 21 and bell shell 1, the outer ring Spielpassung of exhibition square ring 3 and rotary bearing 21, rotary bearing 21 can rotate in exhibition square ring 3, exhibition square ring 3 is contained in chute 11, the inner hole section of exhibition square ring 3 is trapezoidal, open up the axle center of larger diameter end towards trident bearing 2 of the endoporus of square ring 3, the outer surface of exhibition square ring 3 is cambered surface, thus be convenient to exhibition square ring 3 move in chute 11, the exhibition outer surface of square ring 3 and the corner of end face are arc transition, ball cage is moved in chute 11 by exhibition square ring 3, rotary bearing 21 motion in exhibition square ring 3, effectively can increase the corner about 3 ° of ball cage, thus improve the ability of automobile strain burst situation, improve the safety coefficient of automobile, simultaneously can the exhibition square ring 3 of sheathed different size as required, thus adapt to different situations or bell shell 1, substantially increase the adaptability of trident bearing 2.
Exhibition square ring 3 is formed from steel, and the intensity of steel is comparatively large and wear resistance is good, can commercially purchase easily, and exhibition square ring 3 also can adopt other intensity and the good material of wear resistance is made.
Compared with prior art, intensity of the present invention is large, and wear resistance is good, adds the corner of ball cage simultaneously.
Be only a specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
