Abstract
The invention discloses a universal joint which comprises a socket member and a plug member. The plug member is movably connected onto the socket member through a connector, the socket member is provided with two opposite open grooves, the spherical face is arranged at the connecting end of the plug member connected with the socket member, the outer diameter of the spherical faces is identical to the inner diameter of the socket member, the spherical face end is provided with two opposite holes in the radial direction, connecting shafts penetrate the holes, annular grooves are arranged at two ends of each connecting shaft and are respectively in sleeved connection with sliding blocks, and the sliding blocks are limited through locking members and respectively matched with the open grooves. Compared with the prior art, the universal joint has the advantages that a universal swing angle meets the using requirement, disconnection and jointing are facilitated, the required time is short, and the universal joint has large torque transfer capacity and is high in transmission accuracy and using reliability.
Description
Technical field
The present invention relates to a kind of universal joint.
Background technique
Spiral weld-pipe mill needs a kind of can the disengaging fast, and joint that again can universal wide-angle transmitting torque, uses sliding cross coupling in the past, transmission accuracy is poor, and transmitting torque is little, and rotating speed is little, use inconvenience, can not meet user demand, need to design a kind of Novel joint that meets usage requirement.
