[0029] From the above, it can be known that when disassembling the bearing assembly 3, the multiple locking studs 10 are loosened to separate the cover assembly 5 from the bearing box 1, and the flange cover 501 can be removed from one side of the bearing box 1, so that the stop end face 504 in the flange cover 501 is separated from the top ring 404 in the quick-release component 4, so that the top ring 404 can be removed, and a universal manual hydraulic pump is used and its end is installed in the pressure charging hole 14 on one side of the bearing box 1. After the manual hydraulic pump is pressurized, the pressure can be introduced into the installation groove 2 inside the bearing box 1 through the pressure charging hole 14, so that the quick release in the installation groove 2 The component 4 can slide in the installation groove 2. When the snap ring 401 in the quick-release component 4 moves out of the installation groove 2 for a certain distance, the snap ring 401 can be removed from the installation groove 2 by depressing the quick-release groove 403 outside the snap ring 401.

There is no need to assist in the lifting of the universal manual hydraulic pump. The operation can be completed by one person, and the safety hazards are greatly reduced. No professional technicians are required, and the efficiency is high. The redeployment of the bearing assembly 3 can be quickly realized. When the bearing assembly 3 is installed in the bearing box 1, after opening the cover assembly 5, the bearing assembly 3 is pushed into the installation groove 2 in the bearing box 1, and the snap ring 401 in the quick-release component 4 is pushed between the outer wall of the bearing and the installation groove 2. No tooling is required for auxiliary operation. The O-ring 7 and the skeleton seal ring 503 are respectively installed on one side of the flange cover 501 and in the through hole 6. At the same time, the top ring 404 is placed between the flange cover 501 and the snap ring 401. Then, the flange cover 501 is installed on the bearing box 1 through a plurality of locking studs 10, and the locking studs 10 are tightened according to the specified torque. The quick-release component 4 is pushed to move through the stop end face 504 on the flange cover 501. Since the quick-release component 4 and the mounting groove 2 in the bearing box 1 are tapered, when the flange cover 501 is pushed forward, the outer diameter of the bearing assembly 3, the quick-release component 4 and the bearing box 1 begin to be compressed and generate an interference fit to ensure the interference fit of the outer ring of the bearing body 301. By optimizing the design of the bearing box 1 and the quick-release component 4, when the end face of the flange cover 501 is compressed with the end face of the bearing box 1, the interference fit of the bearing body 301 meets the design requirements, and the integration and deployment of the power transmission mechanism parts can be quickly completed.

The shaft passes through the power transmission mechanism, and the bearing assembly 3 inside the bearing box 1 and the shaft adopt a clearance fit, so that the bearing assembly 3 can be directly installed on the shaft without other auxiliary equipment; Push the bearing assembly 3 into the mounting groove 2 in the bearing housing 1, push the snap ring 401 in the quick-release component 4 between the outer wall of the bearing and the mounting groove 2, install the O-ring 7 and the skeleton seal ring 503 on one side of the flange gland 501 and in the through hole 6 respectively, and place the top ring 404 between the flange gland 501 and the snap ring 401, then install the flange gland 501 on the bearing housing 1 through a plurality of locking studs 10, and tighten the locking studs 10 according to the specified torque; The quick-release component 4 is pushed to move by the stop end face 504 on the flange gland 501. Since the quick-release component 4 and the mounting groove 2 in the bearing box 1 are tapered, when the flange gland 501 is pushed, the outer diameter of the bearing assembly 3, the quick-release component 4 and the bearing box 1 begin to be compressed and an interference is generated to ensure the interference fit of the outer ring of the bearing body 301. The end face of the flange gland 501 is compressed with the end face of the bearing box 1 and locked by a plurality of locking studs 10, so that the integration and deployment of the power transmission mechanism parts can be completed; When removing the bearing assembly 3, the plurality of locking studs 10 are loosened to separate the cover assembly 5 from the bearing box 1, and the flange gland 501 can be removed from the bearing box 1, so that the stop end face 504 in the flange gland 501 is separated from the top ring 404 in the quick-release component 4. A universal manual hydraulic pump is used and its end is installed in the pressure-charging hole 14 on one side of the bearing box 1. After the manual hydraulic pump is pressurized, the pressure can be introduced into the mounting groove 2 inside the bearing box 1 through the pressure-charging hole 14, so that the quick-release component 4 in the mounting groove 2 can slide in the mounting groove 2; When the snap ring 401 in the quick-release component 4 is moved out of the mounting groove 2 for a certain distance, the snap ring 401 can be removed from the mounting groove 2 by depressing the quick-release groove 403 outside the snap ring 401. At this time, the bearing assembly 3 is in a free movable state, and the snap ring 401 is completely separated from the bearing assembly 3, so the bearing assembly 3 can be removed from the bearing box 1.
