Drawings
FIG. 1 is a schematic cross-sectional view of one embodiment of the present utility model.
FIG. 2 is a schematic partial cross-sectional view of one embodiment of the present utility model.
FIG. 3 is a schematic partial cross-sectional view of one embodiment of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the high-stability embedded ball-and-socket joint comprises a shell 1 and a three-ball pin assembly 3, wherein a ball channel 11 is arranged in the shell, the three-ball pin assembly comprises a three-pin frame 32, the three-pin frame comprises a shaft neck 33, an inner ball ring 34 is arranged outside the shaft neck, an outer ball ring 31 is arranged outside the inner ball ring, and an elastic positioning mechanism for limiting the inner ball ring is arranged between the outer ball ring and the inner ball ring. The spring can reduce the direct contact between the inner ball ring and the outer ball ring by providing proper force balance, thereby reducing the friction force; the top ball can provide rolling support, so that the friction area is reduced, and the friction force is further reduced. The friction reducing effect is particularly important in the fields of high-speed rotating machinery, precision machinery, high-load machinery and the like, and can improve the efficiency and service life of a mechanical system.
In this embodiment, as shown in the figure, the elastic positioning mechanism includes an elastic member 51 and a top ball 52, one end of the elastic member abuts against the inner wall of the outer ball ring, the other end abuts against the top ball, and one end of the top ball contacts with the outer wall of the inner ball ring.
In this embodiment, as shown in the drawing, the outer wall of the inner ball ring is provided with a first groove 342 for the top ball portion to extend into. The steel ball can not be separated, and the use is more stable.
In this embodiment, as shown in the figure, the elastic member is a spring.
In this embodiment, as shown in the figure, the outer ball ring is provided with a positioning groove 313, and one end of the spring is provided in the positioning groove. The spring can not be separated, and the use is more stable.
In this embodiment, as shown, the inner wall of the outer ball ring is provided with a plurality of collars 312 for contact with the inner ball ring. Friction is reduced.
In this embodiment, as shown in the drawing, a boss 111 with an arc-shaped surface is disposed in the lane, and a second groove 311 slidably matched with the boss is disposed on the outer wall of the outer ball ring. The contact area of the shell ball channel and the three-ball pin ball ring is increased, and the load is shared, so that the torque transmission capacity is improved, the abrasion is reduced, the noise and vibration are reduced, and the service life of the universal joint is prolonged. It can still maintain stable and reliable transmission effect under the condition of high load and high-speed motion.
In this embodiment, as shown in the figure, the bosses are disposed on two sides of the outer ball ring. The operation is more stable.
