Sprocket process detailed explanation

Sprocket process detailed explanation
1. Overview
Sprocket is one of the important parts in mechanical transmission, its production process includes raw material selection, processing and heat treatment and other key processes. The following will introduce the sprocket process in detail.
2. Selection of raw materials
There are many types of sprocket materials, and many factors such as the use environment, transmission power and wear resistance need to be taken into account when choosing. The materials usually chosen are 45# steel, 40Cr, 20CrMnTi and so on. 45# steel is suitable for low power transmission, 40Cr and 20CrMnTi are suitable for high power transmission. In addition, when selecting materials, it is also necessary to consider factors such as size and hardness to meet the requirements of the sprocket for strength and toughness.
3. Processing
(1) Turning
First, the raw material is turned so that it becomes a cylindrical blank of a certain precision and size.
(2) After the gear machining is turned

The blank is put into the CNC boring machine or the automatic boring machine for gear machining. Gear processing needs to pay attention to is to ensure that the ratio of tooth width and tooth depth is reasonable, the number of gear teeth is accurate, the amount of dislocation is small and other factors.

(3) Tapping
After finishing the gear machining, it is necessary to tap. Tapping is generally carried out by processing lathes, and the quality of tapping is directly related to the reliability and service life of the sprocket, so it is necessary to operate in strict accordance with the process specifications.
Step 4 Heat treatment
After the completion of the above process, the finished sprocket is heat treated to improve its hardness and wear resistance. Commonly used heat treatment processes are quenching and carburizing, of which quenching is suitable for low carbon sprockets, carburizing is suitable for high carbon sprockets. Heat treatment should be noted that the appropriate process parameters need to be selected according to the different characteristics of the material and the use of the sprocket environment.
Step 5 Summarize
Sprocket production process includes raw material selection, processing and heat treatment and other links, the quality of each link is directly related to the final sprocket quality and service life. Therefore, in the production of sprockets should be strictly in accordance with the process operation, follow the scientific, rigorous, fine principles, in order to produce high-quality sprocket products.
