[0021] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is combined with the drawing and example, and the utility model is further explained in detail.

[0022] In one embodiment, as shown in Figs. 1-3 A split wear plate type elastic coupling with brake wheel, including wear plate base 1, the inner wall of wear plate base 1 is connected with wheel hub shaft sleeve 6 through screw, wheel hub shaft sleeve 6 is connected with optical shaft sleeve 2 through screw, and plum blossom pad 5 is arranged between optical shaft sleeve 2 and wheel hub shaft sleeve 6, and four wear plates 4 that are circumferentially distributed are arranged on the side of wear plate base 1.

[0023] In one embodiment, wear plate 4 is connected with wear plate base 1 through screw.

[0024] Since wear plate 4 is connected through screw, when wear plate 4 is worn, it can be directly taken down through unlocking screw, without removing motor again for replacement, and use is more convenient.

[0025] In one embodiment, the wear plate base 1 is provided with two symmetrical check ring grooves, and the elastic check ring 3 is connected to the inner side of the check ring groove. The inner ring of the wear plate base 1 is in tolerance with the side of the hub sleeve 6. The elastic check ring 3 can be installed in the shaft groove or the hub groove of the coupling, and is clamped in the groove through elastic deformation, limiting the relative movement of the shaft and the hub in the axial direction, ensuring that the two shafts connected by the coupling remain relatively fixed in the axial position, so that the power can be stably transmitted, preventing the normal operation of the equipment from being affected by the axial movement.

[0026] In one embodiment, the wear plate base 1 is provided with a chamfer.

[0027] In one embodiment, the material of the wear plate 4 is tin bronze, nylon, carbon fiber, etc.

[0028] The wear plate 4 can be replaced according to different use environments, and can be suitable for various working conditions, such as high acid and alkali scenes, which can use wear plates 4 made of corrosion-resistant nylon carbon fiber material, high temperature areas use wear plates 4 made of alloy steel material, use wear plates 4 of different materials in different environments, significantly improving the service life of the coupling in different environments.

[0029] In one embodiment, the material of the elastic check ring 3 is spring steel.

[0030] The above embodiment discloses a split wear plate type elastic coupling with a brake wheel, and the specific working principle is as follows:

[0031] The split design is adopted, the original bolt-connected brake wheel is changed to a split wear plate structure, the contact surface material is upgraded, the maintenance difficulty and time are shortened, and the overall life of the coupling is improved.

[0032] The conventional elastic coupling with a brake wheel generally has a whole brake wheel connected by bolts. Once the brake wheel is worn, the coupling will vibrate, and the motor must be removed before replacement.

[0033] Since the wear plate 4 is connected by screws, when the wear plate 4 is worn, it can be directly removed by unlocking the screws, without the need to remove the motor for replacement, and the use is more convenient.

[0034] And the wear plate 4 can be replaced according to different use environments, and can be suitable for various working conditions, such as high acid and alkali scenes, which can use wear plates 4 made of corrosion-resistant nylon carbon fiber material, high temperature areas use wear plates 4 made of alloy steel material, use wear plates 4 of different materials in different environments, significantly improving the service life of the coupling in different environments.

[0035] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
