Description

Technical Field

[0002] A sprocket is a wheel with cog-shaped sprocket teeth, which is used to mesh with blocks with accurate pitch on link chains or cables. Sprockets are widely used in engines, and they play an important role in transmitting power in these mechanical systems. The sprocket tooth shape must ensure that the chain links can enter and exit the meshing smoothly and freely, minimize the impact and contact stress of the chain links during meshing, and be easy to process. The sprocket material should ensure that the teeth have sufficient strength and wear resistance. Therefore, the sprocket tooth surface is generally heat treated to achieve a certain hardness. The wheel disc is the main component of the sprocket. It is usually made of casting or cold heading and is made of steel. Some wheel discs are also made of aluminum alloy, copper alloy and titanium alloy.

[0003] However, it still has some disadvantages. For example, when the die-casting mold of the engine sprocket shell is in use, the newly formed engine sprocket shell is relatively weak, so the engine sprocket shell is easily damaged when it is taken out.
