When installing the bearing, first pass the tapered sleeve 401 onto one end of the connecting shaft 402, then adjust the position of the tapered sleeve 401, and wait for the adjustment to be completed. After the tapered sleeve 401 is in position, the inner ring 2 with the outer ring 1 is passed through one end of the tapered sleeve 401 until one side of the inner ring 2 is against the tapered sleeve 401, and then the gasket 403 is passed through one end of the tapered sleeve 401, so that one side of the gasket 403 is tightly against the inner ring 2, and then the locking nut 404 is passed through one end of the tapered sleeve 401, and the locking nut 404 is rotated with a tool. At this time, the inner groove 407 of the locking nut 404 continuously rubs and squeezes the tapered sleeve 401, and under continuous rotation, the locking nut 404 tightly squeezes the gasket 403 to the side of the inner ring 2, and then a tool is used to press the locking piece 405 on the surface of the gasket 403 into the locking groove 406, so as to prevent the locking nut 404 from loosening during subsequent use.

[0022] Furthermore, one side of the surface of the connecting shaft 402 is in contact with the tapered sleeve 401, and one side of the surface of the tapered sleeve 401 is in contact with the inner ring 2.

[0024] Furthermore, six groups of locking grooves 406 are provided, and the locking grooves 406 are distributed in a circular shape with equal intervals. Through the setting of the locking grooves 406, when in use, the locking grooves 406 can provide an installation position for the locking plate 405, and cooperate with the locking plate 405 to play a role in preventing loosening.

[0025] Furthermore, the outer mechanism 3 includes a lower shaft seat 301, an upper shaft seat 302, a threaded groove 303, a threaded hole 304 and a bolt 305. One side of the surface of the outer ring 1 is connected to the lower shaft seat 301, and one side of the surface of the outer ring 1 is connected to the upper shaft seat 302. One side of the surface of the lower shaft seat 301 is provided with a threaded groove 303, and one side of the surface of the upper shaft seat 302 is provided with a threaded hole 304.

When the threaded groove 303 and the threaded hole 304 are horizontally aligned, use the bolt 305 to threadably connect the threaded hole 304 and the threaded groove 303, thereby completing the installation of the bearing to the bearing seat.

[0026] Furthermore, one end of the bolt 305 matches the size of the threaded groove 303, and one end of the bolt 305 matches the size of the threaded hole 304. Through the setting of the bolt 305, when in use, the bolt 305 serves as a connecting piece, which can tightly connect the upper shaft seat 302 and the lower shaft seat 301 together, and by screwing into the threaded hole 304 and the threaded groove 303, it provides sufficient tightening force to ensure that the bearing is stably installed in the bearing seat.

When the bolt 305 is screwed in, the connection and fixation of the lower shaft seat 301 and the upper shaft seat 302 are achieved.

[0028] Working principle: When installing the bearing, first pass the tapered sleeve 401 to one end of the connecting shaft 402, and then adjust the position of the tapered sleeve 401. After adjusting the position of the tapered sleeve 401, pass the inner ring 2 with the outer ring 1 to one end of the tapered sleeve 401 until one side of the inner ring 2 is against the tapered sleeve 401. Then pass the gasket 403 to one end of the tapered sleeve 401, so that one side of the gasket 403 is tightly against the inner ring 2. Then use the locking nut 404 to pass it to one end of the tapered sleeve 401, and use a tool to rotate the locking nut 404. At this time, the inner screw groove 407 of the locking nut 404 continuously rubs and squeezes the tapered sleeve 401, and under continuous rotation, the locking nut The nut 404 tightly squeezes the gasket 403 to the side of the inner ring 2, and then uses a tool to press the locking piece 405 on the surface of the gasket 403 into the locking groove 406 to prevent the locking nut 404 from loosening during subsequent use. When the installed bearing is then installed into the bearing seat, first clamp the inner side of the lower shaft seat 301 to one side of the outer ring 1, and then press the lower shaft seat 301 to adjust it. Then, clamp the upper shaft seat 302 with the other side of the outer ring 1 and adjust it. When the threaded groove 303 and the threaded hole 304 are horizontally aligned, use the bolt 305 to thread the threaded hole 304 and the threaded groove 303 to complete the installation of the bearing into the bearing seat.
