However, when the axis of the driving wheel rotates, it will be affected by the load and move left and right. The left and right movement of the axis of the driving wheel will cause frequent failures of the coupling of the motor, and at the same time, damage to the thrust end cover of the bearing will be caused. Content of the Utility Model

[0003] To solve the problems raised in the above background technique, the utility model provides a single-convex bearing with a single-sided flange, which solves the problem that the axis of the driving wheel will move left and right under the influence of the load when rotating.

[0004] To achieve the above object, the utility model provides the following technical solution: A single-convex bearing with a single-sided flange, including an axis and a roller bearing. A pulley is fixedly installed on the outside of the axis. Grooves are formed on the outer surface of the pulley. A fixing ring is fixedly installed on the outside of the axis. Bolts are installed inside the fixing ring in a threaded manner. A thrust end cover is installed on one side of the fixing ring in a threaded manner through the bolts. A coupling is fixedly installed at one end of the axis. A transmission gear is fixedly installed at one end of the coupling. A bearing sleeve is fixedly installed on the outside of the axis. Rollers are installed inside the roller bearing in a rolling manner.

[0005] Preferably, the inner sleeve edge of the bearing sleeve is a single-sided flange, and the two bearing sleeves are installed on the axis in opposite directions.

[0006] Preferably, the roller bearing is penetrated by the axis, and the bearing sleeve is located inside the roller bearing.

[0007] Preferably, one end of the thrust end cover is equal in diameter to the roller bearing, and the diameter of the ring formed by the single-sided flange of the bearing sleeve is also equal to the diameter of the roller bearing.

[0008] Preferably, the grooves formed on the surface of the pulley are circular, and these circular grooves are arranged in a linear array on the surface of the pulley.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The single-convex bearing with a unilateral flange can prevent the pulley center from moving left and right when the pulley center is loaded and vibrates, causing damage to the coupling and the thrust end cover by customizing the inner sleeve edge of the bearing sleeve into a unilateral flange and installing the two bearing sleeves on the axis in opposite directions. The axis passes through the roller bearing, and the bearing sleeve is located inside the roller bearing, enabling the axis and the bearing sleeve to rotate through the rollers in the roller bearing.

[0011] 2. For the single-convex bearing with a unilateral flange, by setting one end of the thrust end cover to have the same diameter as the roller bearing, and the diameter of the ring formed by the unilateral flange of the bearing sleeve is also the same as the diameter of the roller bearing, the thrust end cover and the bearing sleeve can accurately limit the roller bearing without affecting other parts. By linearly arraying circular grooves on the surface of the pulley, the friction can be increased when the belt drives the pulley, enabling the pulley to operate better.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: a single-convex bearing with a single-sided flange, including a shaft center 1 and a roller bearing 2. A pulley 3 is fixedly installed on the outside of the shaft center 1. A groove 4 is provided on the outer surface of the pulley 3. A fixing ring 5 is fixedly installed on the outside of the shaft center 1. A bolt 6 is installed inside the fixing ring 5 by threading. A thrust end cover 7 is installed on one side of the fixing ring 5 by threading with the bolt 6. A coupling 8 is fixedly installed at one end of the shaft center 1. A transmission gear 11 is fixedly installed at one end of the coupling 8. A bearing sleeve 9 is fixedly installed on the outside of the shaft center 1. A roller 10 is installed inside the roller bearing 2 in a rolling manner.

[0020] In this embodiment, by customizing the inner sleeve edge of the bearing sleeve 9 into a single-sided flange and installing the two bearing sleeves 9 in opposite directions on the shaft center, it can prevent the shaft center of the pulley from moving left and right when vibrating under load, causing damage to the coupling and the thrust end cover. By installing the roller bearing 2 through the shaft center 1 and the bearing sleeve 9 being located inside the roller bearing 2, the shaft center 1 and the bearing sleeve 9 can rotate through the roller 10 in the roller bearing 2. By setting one end of the thrust end cover 7 to be equal in diameter to the roller bearing 2 and the diameter of the ring formed by the single-sided flange of the bearing sleeve 9 to also be equal to the diameter of the roller bearing 2, the thrust end cover 7 and the bearing sleeve 9 can accurately limit the roller bearing 2 without affecting other parts. By linearly arranging the circular grooves 4 on the surface of the pulley 3, it can increase the friction when the belt drives the pulley 3, making the pulley 3 operate better.

[0021] Specifically, the inner sleeve edge of the bearing sleeve 9 is a single-sided flange, and the two bearing sleeves 9 are installed in opposite directions on the shaft center. By customizing the inner sleeve edge of the bearing sleeve 9 into a single-sided flange and installing the two bearing sleeves 9 in opposite directions on the shaft center, it can prevent the shaft center of the pulley from moving left and right when vibrating under load, causing damage to the coupling and the thrust end cover.

[0022] Specifically, the roller bearing 2 is passed through by the shaft center 1 and the bearing sleeve 9 is located inside the roller bearing 2. By installing the roller bearing 2 through the shaft center 1 and the bearing sleeve 9 being located inside the roller bearing 2, the shaft center 1 and the bearing sleeve 9 can rotate through the roller 10 in the roller bearing 2.

[0023] Specifically, one end of the thrust end cover 7 is equal in diameter to the roller bearing 2, and the diameter of the ring formed by the single-sided flange of the bearing sleeve 9 is also equal to the diameter of the roller bearing 2. By setting one end of the thrust end cover 7 to be equal in diameter to the roller bearing 2 and the diameter of the ring formed by the single-sided flange of the bearing sleeve 9 to also be equal to the diameter of the roller bearing 2, the thrust end cover 7 and the bearing sleeve 9 can accurately limit the roller bearing 2 without affecting other parts.

[0024] Specifically, the grooves 4 formed on the surface of the pulley 3 are annular, and these annular grooves 4 are arranged in a linear array on the surface of the pulley 3. By arranging the annular grooves 4 in a linear array on the surface of the pulley 3, the friction can be increased when the belt drives the pulley 3, enabling the pulley 3 to operate better.

[0025] The working principle or usage process of the present utility model: When the present utility model is in use, first place the roller bearing 2 inside the limiting device, and then drive the rotating shaft center 1 of the pulley 3 through the belt. The rotating shaft center 1 rotates inside the roller bearing 2 to drive the coupling 8 to rotate and drive the transmission gear 11 to provide power for the required crusher. When the rotating shaft center 1 rotates, the flanges on the two bearing sleeves 9 and the thrust end cover 7 limit the left and right movement of the roller bearing 2, preventing the rotating shaft center 1 from moving left and right when vibrating under load, thereby causing damage to the coupling 8 and the thrust end cover 7.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can understand and utilize the present utility model well.
