Problems solved by technology
[0002] In the hoisting and hoisting mechanism, a ball joint type drum coupling is often used between the reducer and the drum, and its general structure is: two halves are arranged on both sides of the spherical bushing, one of which is a The flange half body and the other non-flange half body are connected by a tie rod. The tie rod will loosen or creep when it vibrates during work, so that the non-flange half body and the torsion key are only in contact without force. The flange half will bear all the force in the work, and the working surface of the torsion key in contact with it will also be reduced, which will lead to an increase in the extrusion stress of the key and the groove, resulting in increased wear and even plastic deformation of the torsion key , so that the coupling is damaged prematurely, thus greatly reducing the service life of the coupling and increasing the operating cost

Embodiment approach 3
[0021] As a third embodiment of the present invention, the front flange 1-1 and the rear flange 1-2 are directly positioned through the fit of end-face teeth, and the two flanges are tightly connected by fasteners installed on site. Under this structure, the end teeth not only limit the relative movement of the front and rear flanges, but also ensure that the flanges are not easy to loosen when the coupling is working, and ensure that the two flanges are evenly stressed, thereby further improving the coupling after installation. Rigidity improves integrity. In addition, when the contact surfaces between the torque key and the two flanges wear unevenly, the end face teeth can limit the relative movement between the two flanges and ensure the relative position of the two flanges. At the same time, the end teeth can also transmit torque, which is higher in rigidity and strength than couplings of the same specification.

The invention discloses a high-strength spherical hinge type coupler which comprises a front flange, a rear flange, a spherical shaft sleeve, a front sealing cover, a rear sealing cover, and a plurality of torsion keys distributed uniformly, wherein the front end and the read end of the spherical shaft sleeve are sleeved with the front flange and the rear flange respectively; the spherical shaft sleeve is slidingly matched with a small gap between inner ring surfaces of the front flange and the rear flange; the torsion keys are arranged in key grooves and holes among the front flange, the rear flange and the spherical shaft sleeve; and the front sealing cover and the rear sealing cover are pressed on outer end faces of the front flange and the rear flange and compressed by fasteners. Compared with the existing spherical hinge type coupler in the same size, the spherical hinge type coupler is longer in service life and reduces the working cost. In addition, the bearing capacity of the spherical hinge type coupler is improved greatly, and the processing cost is reduced.
Description
technical field [0001] The invention relates to a ball-joint coupling, which is a key equipment in a crane and is mainly suitable for the connection between a reducer and a reel in a crane in a factory, a wharf, or a hoisting mechanism and the connection of other similar structures. Background technique [0002] In the hoisting and hoisting mechanism, a ball joint type drum coupling is often used between the reducer and the drum, and its general structure is: two halves are arranged on both sides of the spherical bushing, one of which is a The flange half body and the other non-flange half body are connected by a tie rod.
