Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chain ring processing, in particular to a processing method of a flat arc tooth joint chain ring for mining. BACKGROUND

[0002] The flat arc tooth joint chain ring for mining is an important accessory in the transmission structure of the scraper conveyor in the coal mine underground, which is mainly used for linking the transmission chain and the scraper and is an important stress part, and is a consumable product with a large amount of use. Once the joint chain ring is broken, the whole mining face will be shut down. If the production quality and production efficiency of the joint chain ring are improved, the maintenance and downtime of the mining equipment can be reduced, thereby improving the production capacity of the coal mine and reducing the manpower and time.

[0003] The structure of the flat arc tooth joint chain ring for mining includes inner teeth and outer teeth, and the shapes of the inner teeth and the outer teeth are irregular shapes, and the processing thereof has high difficulty.

[0006] Secondly, the wire cutting for cutting out the tooth type can only be a straight surface, and the arc tooth joint chain ring with a straight surface has a smaller contact area between the teeth than the arc tooth joint chain ring with an arc surface, so that the actual breaking tension is lower than that of the normal arc tooth shape.
