Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
with reference to the accompanying drawings: the end face pin type rigid coupler in the embodiment comprises a left connecting flange 1 and a right connecting flange 8, wherein the end faces of the left connecting flange 1 and the right connecting flange 8 are connected through a fastening bolt 2, a nut 3 and a gasket 4, a torsional shear pin 7 is arranged on the end disc excircle step of the left connecting flange 1 and the right connecting flange 8, an anti-falling ring 5 is arranged on the torsional shear pin 7, and a fastening bolt 6 is arranged on the anti-falling ring 5.
The fastening bolt 2 is an 8.8-grade high-strength bolt.
The fastening bolt 6 is an 8.8-grade high-strength bolt.
The left connecting flange 1 and the right connecting flange 8 are of forged piece structures, through holes are formed in the middle of the forged piece structures, and inner holes of the flanges are preferably connected with a shaft in an internal spline mode, but not limited to the internal spline mode. The left end face and the right end face are respectively provided with a positioning clamping groove which is matched with the left end face and the right end face in a concave-convex mode, and the left flange plate and the right flange plate can be conveniently assembled. And bolt penetrating holes are axially formed in the end face discs of the left connecting flange 1 and the right connecting flange 8. After the left connecting flange and the right connecting flange are connected, a flange joint seam surface is used as a parting surface of the pin hole, the pin holes are drilled and twisted along the radial depth direction, the pin holes are uniformly distributed along the excircle of the end face disc and are staggered with the bolt penetrating holes of the end face disc, and the size and the precision of the pin holes are configured with the torsional shear pins 7. The torsional shear pin 7 is preferably a standard conical pin, but is not limited to a conical pin, and the size of the torsional shear pin 7 is selected according to the transmitted torque and impact load. The fastening bolt 2 is an 8.8-level high-strength bolt, and a fastening nut, a washer and a fastening bolt are selected and matched. The anti-drop ring 5 is formed by bending flat steel, and round holes for penetrating through the fastening bolts are formed in two sides of the anti-drop ring 5. The fastening bolt 6 adopts an 8.8-level high-strength bolt, and the anti-drop ring 5 presses the torsional shear pin 7 to prevent the shear pin from dropping off in the operation process.
The technical conception of the invention is as follows: the rigid coupling has the advantages that the manufacturing, processing and maintenance of the rigid coupling are simple, the idea that shearing is carried by replacing a complex end face tooth structure with the pin which is easy to obtain is adopted, the defects of the rigid coupling are overcome, and large torque and impact force can be carried in connection through the pin structure, so that the aim of stably transmitting vibration impact and large torque load functions by using simple and easy-to-process parts is fulfilled.
