Description

Technical Field

[0002] The sleeve pin coupling is composed of two semi-couplings with the same structure. The only difference between the two is the assembly dimension for the shaft. The two semi-couplings are connected by pins with elastic elements. An intermediate ring is installed between the elastic elements on the pins. The ring sleeve floats and is connected to the mutually centered end face discs by pins. Along the end face, it wraps the two semi-couplings. The torque is transmitted from one semi-coupling to the other through the elastic elements installed on the pins. The pins and the semi-couplings are non-rigidly connected to enable the pins to be loaded smoothly and at the same time greatly reduce the lateral force.

In addition, the first protection shell and the second protection shell are in contact with the snap ring to seal and block the connection at both sides. Finally, the hook is clamped with the connection groove, and the connecting plate is used to connect and fix the splicing of the first protection shell and the second protection shell.

[0008] Preferably, the number of the connecting components is two, and two adjacent connecting components are connected and fixed by fastening bolts.

[0009] The two connecting components are connected and fixed by fastening bolts.

[0010] Preferably, clamping grooves are formed on both sides of the outer circumferential wall of the fixing ring, and sliding grooves are formed on both sides of the inner wall of the fixing pipe.

[0011] By inserting the clamping grooves on both sides of the fixing ring with the clamping blocks, the installation of the protection component can be positioned, and the outer shaft rod is inserted and connected through the sliding grooves.

[0012] Preferably, insertion slots are formed on the inner walls at both ends of the first protective shell, and the insertion slots are in insertion fit with the U-shaped blocks.

[0013] By inserting the insertion slots with the U-shaped blocks, after the first protective shell and the second protective shell are spliced, the gaps are blocked.

[0016] Preferably, hooks are fixed at the four corners of the arc-shaped inner wall of the connecting plate, and connecting grooves adapted to the hooks are formed at the four corners of the arc-shaped outer walls of the first protective shell and the second protective shell.

[0017] By clamping the hooks with the connecting grooves, the connecting plate connects and fixes the splicing of the first protective shell and the second protective shell.
