Description

Technical Field

[0001] The utility model application relates to the technical field of sprocket wheel edges, in particular to a sprocket wheel edge with a cleaning structure. Background Art

[0002] A sprocket is a wheel with a toothed buckle rim, which is used to mesh with a block with accurate pitch on a link chain or cable. Sprockets are widely used in mechanical transmission in chemical industry, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries. The sprocket material should ensure that the teeth have sufficient strength and wear resistance.

[0003] When the friction of the outer sprocket wheel edge of the dry wheel-side brake is in a dry state, the wheel edge is easily adhered to dust and impurities when the sprocket is in use. In the dry state, the retained dust and impurities are likely to increase the friction between the sprocket and the link chain, thereby easily increasing the friction of the sprocket wheel edge. Most of the existing sprocket wheel edges do not have a cleaning structure. Some sprocket wheel edges with a cleaning structure use a transmission sliding structure to drive a fan for cleaning. However, since the fan cannot control the cleanliness of the surrounding airflow when blowing, it is easy to drive debris to the sprocket wheel edge while blowing and cleaning, resulting in uncontrollable actual cleaning effect. Summary of the invention

[0004] In order to solve the problem that impurities on the surface of the existing sprocket wheel edge are difficult to clean during use and easily increase the wear of the sprocket wheel, the utility model provides a sprocket wheel edge with a cleaning structure to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sprocket wheel edge with a cleaning structure comprises a sprocket body and a mounting back plate, a fixing rod is fixed to the front side of the mounting back plate on the side of the sprocket body, and a rotating connecting rod is rotatably connected to the fixing rod via a bearing, the rotating connecting rod is detachably connected to the mounting sleeve, and a cleaning brush is fixedly arranged on the outer surface of the mounting sleeve.

[0007] Furthermore, a connecting rod is fixed to the side of the rotating connecting rod away from the mounting back plate, and a fixing screw is fixed to the side of the connecting rod away from the rotating connecting rod. A positioning slot cooperating with the rotating connecting rod is opened inside the mounting sleeve, and a fixing nut is threadedly sleeved on one end of the fixing screw extending to the outside of the mounting sleeve.

[0009] Furthermore, the cleaning brush is configured to be tooth-shaped to match the wheel edge of the sprocket body, the outer surface of the cleaning brush is in contact with and meshes with the wheel edge of the sprocket body, and the outer ring diameter of the fixing nut is smaller than the outer ring diameter of the mounting sleeve.

[0010] Furthermore, the length of the fixing nut is greater than the length of the positioning slot, the width of the positioning slot is greater than the width of the connecting rod, and the positioning slot is set to be a rectangle that matches the positioning slot, and the diameter of the fixing screw is smaller than the length and height of the connecting rod.

[0011] Furthermore, the cleaning comb is located between two tooth protrusions of the cleaning brush, and the length of the cleaning comb is equal to the length of the depression between the two teeth of the cleaning brush.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the rotatable cleaning brush can drive the cleaning brush to rotate when the sprocket body rotates. When the cleaning brush rotates, it can contact the wheel edge of the sprocket and clean the meshing surface of the wheel edge and the chain, avoiding the phenomenon of increased friction caused by dust and debris on the wheel edge surface. The problem of the existing sprocket wheel edge being difficult to clean impurities on the wheel edge surface during use and easily increasing the wear of the sprocket is solved. No transmission component is required, the structure is simpler, and it is easy to maintain.
