Common raw materials of sprocket and selection of sprocket materials

How to select the material of the sprocket

The sprocket is a kind of transmission equipment, which can be used in conjunction with the transmission chain. Same as the application of transmission gear and rack

45 # steel is generally selected as the common material of sprocket. Generally, 45 # material chain wheel can already consider the application standard of chain wheel

Naturally, some people choose 40Mn (40 alloy steel) and 45Mn (45 alloy steel). The relativity of alloy steel sprocket is a qualitative difference from that of 45 # sprocket

Natural selection of raw materials for chain wheel should also be based on application requirements. If the speed is low. Low tensile resistance. In the selection of sprocket raw materials, 45 # sprocket raw materials with high cost performance can be selected

sprockets made of stainless steel plates:

The common stainless steel plates for sprockets are 201 stainless steel plates, 304 stainless steel plates and 316 stainless steel plates

It is more prominent that 304 stainless steel plate can consider the requirements for raw materials of sprocket on the basis of 304 corrosion layer

The sprockets made of 201 raw materials are less corrosion resistant than those made of 304 raw materials

316 materials are mostly used in coastal areas. The 316 material sprocket has strong corrosion resistance against salt chemicals

The selection of raw materials for sprockets is based on the main purpose. It can be selected according to such factors as speed ratio, tensile resistance and natural environment

Non-standard sprocket manufacturer

The sprocket manufacturer introduces the structure and application of the sprocket in detail, and points for attention in production and manufacturing:

1. The appearance design of the sprocket tooth shape and its teeth determines that the chain segment should be protected to move in and out of gear stably, and the impact of the chain segment and its contact ground stress under the condition of gear engagement should be minimized, and it should be convenient for production and processing. The appearance of the inner hole which is often used. It is composed of three arcs and their parallel lines, and is called three-arc parallel line appearance design. It uses standard CNC blades to carry out engineering construction, and does not need to draw the appearance design of the inner hole on its construction drawings

2, the sprocket structure has several commonly used structures. If it is small diameter, it will be taken as the overall way

At present, the appropriate industry categories for the use of sprocket products include:

First, it is used in the speed control system software, mostly in the substitute tools and industrial equipment of mechanical automation. The application in this industry is mainly to give full play to the advantages of drives,

and other aspects related to speed, such as industrial production transmission, wheel transmission of cars, etc. Basically, different types of transmission gear products are also needed in the system software that uses sprocket products. Only when several industrial equipment and parts are upgraded and matched can the actual effect of sprocket application be greatly improved

Sprocket is a part with high specified performance. If only heat treatment is performed, its internal mechanism will be symmetrical and its crystal will be fine. Although there is certain strength (generally 45
