Abstract

The invention discloses a timing chain wheel which comprises a chain wheel body; a shaft hole is formed in the chain wheel body; and mounting of the chain wheel body is realized through the shaft hole. According to the scheme disclosed by the invention, the timing chain wheel is improved, first radiating holes are formed in the chain wheel body; the first radiating holes are arranged in the peripheral direction of the chain wheel body; and the first radiating holes are uniformly arranged along the circumference of the chain wheel body, so that mass distribution, in the peripheral direction, of the chain wheel is uniform. A depth extending direction of the first radiating holes is parallel to the axis of the chain wheel body, i.e., the first radiating holes are formed in the axial direction of the chain wheel body; the first radiating holes are formed, so that the radiating area of the chain wheel body is increased, and therefore, heat generated in a rotation process of a chain disc can be effectively radiated, influences, on working efficiency of the timing chain wheel and an engine, of heat are reduced, and service lives of the timing chain wheel and the engine are prolonged.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to a timing sprocket. Background technique [0002] The timing sprocket is an important part of the engine's gas distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake time and exhaust time. [0003] During the working process of the automobile engine, the four processes of air intake, compression, explosion, and exhaust continuously occur in the cylinder, and the timing of each step must match the movement state and position of the piston, so that the air intake, exhaust, and The lifting and lowering of the pistons are coordinated with each other, and the timing sprocket acts as a "bridge" in the engine, which transmits power to the corresponding parts driven by the crankshaft. [0004] During the rotation of the sprocket in the prior art, a large amount of heat will be generated due to fricti...
