[0030] In this way, the shaft sleeve 1 can be connected to the bearing inside the shaft seat or to the rotating shaft as required.
[0031] Detailed usage process of the sleeve with anti-slip mechanism:
[0032] 1. Preparation for connecting the sleeve and the shaft: Ensure that the sleeve 1 and the shaft are clean and free of oil. Check whether the inner ring groove 2, outer ring groove 3 and socket 4 at both ends of the sleeve 1 are intact. Install the push ring 7: Align the inner thread of the push ring 7 with the outer thread of the outer ring groove 3, and screw the push ring 7 to the appropriate position. Ensure that the rubber clamp 10 is correctly installed on the inner ring surface of the push ring 7 and produces elastic deformation to provide tightening force.
[0033] Adjust the clamping block 5: insert your finger into the finger groove 9, and turn the push ring 7 to move along the outer ring groove 3 toward the clamping block 5. The push ring 7 squeezes the inclined surface 1 of the clamping block 5, so that the clamping block 5 is compressed and the elastic band 6 is stretched to produce elastic deformation. Confirm that the clamping block 5 and the elastic band 6 are firmly clamped between the rotating shaft and the sleeve 1.
[0034] Check the tightening effect: Gently try to rotate the sleeve 1 to confirm that there is no looseness or slippage between it and the shaft. If looseness is found, readjust the position of the push ring 7 until the ideal tightening effect is achieved.
[0035] 2. Preparation stage for connecting the sleeve and the inner bearing of the shaft seat: Ensure that the sleeve 1 and the inner bearing of the shaft seat are clean and oil-free. Check whether the inner ring groove 2, reserved groove 11 and socket 2 12 at both ends of the sleeve 1 are intact.
[0036] Install the push ring 2 15: Align the slide groove 16 of the push ring 2 15 with the guide rod 17, and slide the push ring 2 15 to a suitable position along the guide rod 17. Ensure that the rubber ring 22 is correctly installed on the outer ring surface of the push ring 2 15 and produces elastic deformation to provide fastening force.
[0037] Adjust the support block 13: Put your fingers in the pick-up groove 18 and push the push ring 15 to slide along the guide rod 17. The push ring 15 squeezes the inclined surface 2 of the support block 13, so that the support block 13 is compressed and the elastic band 14 is stretched to produce elastic deformation. Confirm that the support block 13 and the elastic band 14 are firmly clamped between the shaft sleeve 1 and the inner bearing of the shaft seat.
[0038] Lock the push ring 2 15: Continue to push the push ring 2 15 until the guide ring 20 is inserted into the card slot 19. Confirm that the rubber sleeve 21 has been clamped between the card slot 19 and the guide ring 20 to produce elastic deformation to lock the position of the push ring 2 15. Check whether the socket 2 12 is clamped between the push ring 2 15 and the inner ring groove 2 to prevent the push ring 2 15 from loosening at will.
[0039] Check the tightening effect: Gently try to move the sleeve 1 to confirm that there is no looseness or displacement between it and the inner bearing of the shaft seat. If looseness or displacement is found, readjust the position of the push ring 2 15 until the ideal tightening effect is achieved.
[0040] Through the above steps, the shaft sleeve with anti-drop mechanism can be firmly connected with the rotating shaft and the inner bearing of the shaft seat. During use, please pay attention to regularly check and maintain the fastening state and elastic deformation of each component to ensure the stability and reliability of the connection.
