[0026] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0027] The embodiment is a high performance carrier roller.

[0028] As Figures 1-4As shown, the device includes a through shaft 2 and a roller body 5. The roller body 5 is fixedly installed on the outer wall of the middle part of the through shaft 2. A sleeve 1 is movably sleeved on the outer wall of the roller body 5. A keyway 6 is opened on the upper outer surface of the roller body 5. A key rod 7 is fixedly installed on the upper part of the inner cavity of the sleeve 1. A second limiting baffle 8 is fixedly installed on the outer surface of the left end of the roller body 5, and the second limiting baffle 8 is fixedly installed on the outer wall of the through shaft 2. An external thread ring 4 is opened on the outer wall of the right end of the through shaft 2. A first limiting baffle 3 is provided on the right end of the roller body 5. An internal thread ring 12 is opened in the middle of the outer surface of one side of the first limiting baffle 3.

[0029] After the sleeve 1 is fitted onto the outer wall of the roller body 5, the key rod 7 is inserted into the keyway 6; the first limiting baffle 3 is threadedly connected to the position of the external thread ring 4 in the through shaft 2 through the internal thread ring 12; the second limiting baffle 8 has a mounting hole 9 on the outer surface of the side near the sleeve 1, and a compression spring 10 is installed in the mounting hole 9; one end of the outer surface of the compression spring 10 is fixedly connected to one end of the mounting hole 9, and a movable pin 11 is fixedly installed on the other end of the outer surface of the compression spring 10, with one end of the movable pin 11 extending into the mounting hole 9; the outer wall of the movable pin 11 is slidably connected to the mounting hole 9, and one end of the outer surface of the movable pin 11 is elastically connected to one end of the mounting hole 9 through the compression spring 10.

[0030] It should be noted that this utility model is a high-performance idler roller. A sleeve 1 is installed on the outer wall of the roller body 5. After wear, only the sleeve 1 needs to be replaced, instead of replacing the entire idler roller, saving materials and costs, and improving the overall service life. Replacing the sleeve 1 is faster than replacing the entire idler roller, shortening downtime and improving efficiency. Moreover, the roller body 5 can be reused, reducing resource waste and extending the overall service life. When installing the sleeve 1, the sleeve 1 is fitted onto the outer wall of the roller body 5, and the key 7 on the inner wall of the sleeve 1 is inserted into the keyway 6, improving the stability between the sleeve 1 and the roller body 5 and preventing relative rotation. One end of the external threaded ring 4 presses against the movable pin 11 on one side of the second limiting baffle 8. The movable pin 11 presses against the compression spring 10 along the mounting hole 9. The second limiting baffle 8 limits one end of the sleeve 1. Then, the first limiting baffle 3 is installed and threaded to the position of the external threaded ring 4 of the through shaft 2. The first limiting baffle 3 limits the other end of the sleeve 1. At this time, the compression spring 10 is compressed. The reaction force of the compression spring 10 increases the stability of the threaded connection between the first limiting baffle 3 and the through shaft 2, and eliminates the looseness after the threaded connection.
