What is the raw material of the sprocket. How to choose the material of the sprocket Sprocket is a kind of transmission equipment, which cooperates with transmission chain applications. It is the same as the application of transmission gear with rack and pinion. The common material of sprocket is generally 45#. That is, the general 45# steel. Generally, the sprocket of 45# material can already consider the application standard of the sprocket. Naturally, some people choose 40Mn (40 alloy steel), 45Mn (45 alloy steel). There is a qualitative difference between the sprocket of alloy steel material and the sprocket of 45# material. Natural selection of sprocket raw materials should also be based on application requirements. If the speed is relatively low. The tensile strength is small. In the selection of sprocket raw materials, 45# sprocket raw materials with high cost performance can be selected. Sprocket of stainless steel plate: Common stainless steel plates for sprocket wheels are 201 stainless steel, 304 stainless steel, and 316 stainless steel. What is more prominent is the 304 stainless steel plate, which can consider the requirements for the raw material of the sprocket based on the corrosion resistance level of 304. The sprocket of 201 raw material is relatively inferior to the sprocket of 304 raw material in terms of corrosion resistance. Sprockets made of 316 material are mostly used in coastal areas. The sprocket made of 316 material has strong corrosion resistance against salty chemicals. The selection of raw materials for sprocket is based on the main purpose. It can be selected according to the speed ratio, tensile strength, natural environment and other factors. Non-standard sprocket manufacturers The sprocket manufacturer introduces the structure and application of the lower sprocket in detail: 1. The tooth profile of the sprocket and the appearance design of the teeth must ensure that the chain segment can enter and retreat steadily, and minimize the impact of the chain segment and the ground stress in the case of toothing, and To be convenient for production and processing. It looks like an inner hole that is often used. It is composed of three arcs and parallel lines, and is called a three-arc parallel line design. It selects standard CNC blades for 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 a small diameter, it is usually used as a general way. At this stage, the suitable application of sprocket products includes: First, it is used in speed control system software, which is mostly found in transportation tools and industrial equipment for mechanical automation. The application in this industry is mainly to give full play to the drive, Second, other aspects related to speed, such as industrial production transmissions, car wheel transmissions, etc. Basically, in the system software that uses sprocket products, different types of transmission gear products must be kept forever, and several industrial equipment and parts can be upgraded and matched to obtain good actual effects of sprocket use. The sprocket is a part with high wear resistance. If only heat treatment is required, the internal mechanism can only be balanced and the crystals are fine. Although there is a certain strength (generally 45# is above HB225——250), but such strength cannot consider the wear resistance of the sprocket when it is used. It must be solved by heat treatment and quenching. If the wear resistance is high However, carbonitriding (esterification), heat treatment, and quenching should also be carried out to improve the wear resistance of the sprocket. Therefore, it is not right to simply heat the sprocket and lack the metal surface treatment.
