Description

High-load cross axle universal joint Technical Field The utility model relates to the technical field of cross shafts, in particular to a high-load cross shaft universal joint. Background A cross-shaft joint is a widely used component in mechanical transmissions for connecting two shafts that are not in a common line and for transmitting torque and motion between the two shafts. In automotive transmission systems and other systems, in order to achieve power transmission between rotating shafts with axes intersecting or frequently changing relative positions, universal transmission devices must be used, and cross shafts are an integral component of the universal transmission devices. Based on the above, the inventor finds that the conventional cross joint is usually installed in a relatively compact space, and other parts may be blocked around the cross joint, so that the installation operation space of the shaft sleeve is narrow, the installation tool is difficult to spread, and the installation difficulty and time are increased. Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a high-load cross joint which can achieve a more practical value. Disclosure of utility model The present utility model is directed to a high load cross joint that solves the above-mentioned problems associated with the prior art. In view of the above problems, the technical scheme provided by the utility model is as follows: The utility model provides a high load cross axle universal joint, includes the main part, the main part includes the cross axle, be provided with four bearing portions on the cross axle, four the outside of bearing portion is all overlapped and is equipped with hollow annular plate, the adapter sleeve is installed to the one side of hollow annular plate, four perpendicular grooves have been seted up to the outer wall of adapter sleeve, just the outer wall of adapter sleeve is located one side of four perpendicular grooves and has all been seted up the transverse groove, perpendicular groove is linked together with the transverse groove, the spacing hole has been seted up in the outer wall of adapter sleeve department that is close to the transverse groove, the outside cover of adapter sleeve is equipped with the axle sleeve subassembly, the axle sleeve subassembly includes the axle sleeve body, four arc strips are installed to the bottom of axle sleeve body, adjacent a pair of form the mounting groove between the relative one end of arc strip, four the mount pad is all installed to the inside of mounting groove, the slide is installed to the one side that the mount pad is close to the adapter sleeve, the inside slip of slide is equipped with the slide, the through-hole has been seted up to the center department of slide, the internally mounted sleeve of through-hole, sleeve one end runs through the inside of spacing hole. Further, the vertical groove and the horizontal groove are L-shaped, the outer wall of the sliding seat is in clearance fit with the inner walls of the vertical groove and the horizontal groove, and the inner wall of the limiting hole is in clearance fit with the outer wall of one end of the sleeve, which is far away from the mounting seat. The hollow annular plate is fixedly arranged on the inner side of the connecting sleeve, the hollow annular plate is fixedly arranged on the outer side of the connecting sleeve, the connecting sleeve is fixedly connected with the inner side of the connecting sleeve, and the connecting sleeve is fixedly connected with the outer side of the connecting sleeve. Further, the outer wall of slide and the inner wall clearance fit of slide, inner wall one side rotation of mount pad is connected with the screw rod, the one end of screw rod runs through the mount pad and extends to telescopic inside to with threaded connection between the sleeve. The beneficial effect of adopting above-mentioned further scheme is, because screw rod and sleeve threaded connection, the outer wall of slide and the inner wall clearance fit of slide simultaneously, when the screw rod rotated, the linear movement of slide of being convenient for was realized for the slide moves to the adapter sleeve direction, makes the sleeve keep away from the inside of the one end insertion spacing hole of mount pad, and then realizes the installation fixedly of adapter sleeve and axle sleeve body. Further, the worm wheel is sleeved outside one end, far away from the sleeve, of the screw rod, a worm is connected to the inside of the mounting seat in a rotating mode at a position, close to the worm wheel, of the mounting seat, and the worm wheel are meshed with each other. The worm and worm wheel combined type screw has the beneficial effects that through the cooperation of the worm and the worm wheel, the worm wheel is convenient to drive to rotate when the worm rotates, and then the rotation of the screw is realized
