Description

Technical Field

[0001] The utility model relates to the technical field of sprockets, in particular to a combined high-precision motorcycle sprocket. Background Art

[0002] The sprockets are divided into driving sprockets and driven sprockets. The driving sprocket is installed on the engine output shaft through splines, and the driven sprocket is installed on the motorcycle drive wheel. The power is transmitted to the drive wheel through the chain. Generally, the driving sprocket is smaller than the driven sprocket, which can achieve the effect of reducing speed and increasing torque.

[0003] Thus, a motorcycle sprocket is produced (specifically refer to patent number: 201621123089.1), which includes a sprocket body with multiple circumferentially distributed sprocket teeth, a spline hole is provided in the center of the sprocket body, and is characterized in that a mounting boss protruding from the sprocket body is provided on the left or right side of the sprocket body, and a circular through hole coaxial with the spline hole and equal in diameter is provided in the center of the mounting boss. When the motorcycle sprocket obtained by the utility model is assembled, the splined part of the spline shaft cooperates with the spline hole of the sprocket body, and the smooth part at the end of the spline shaft cooperates with the circular through hole of the mounting boss, thereby realizing a double connection between points and surfaces, so that the spline shaft and the sprocket body are more firmly connected, so that there will be no left and right swinging, and the noise during the operation of the sprocket is also smaller.

[0004] However, when some teeth on the existing sprocket are damaged and need to be replaced, they cannot be disassembled by themselves. Professionals need to be found to disassemble the entire sprocket to complete the task. The teeth cannot be replaced without removing the sprocket, which increases the difficulty of operation and maintenance costs to a certain extent, making it more laborious to disassemble and thus reducing the utilization rate.
