What materials are needed for customized gear processing and production

In the process of gear customization, the small pressure angle gear has a small bearing capacity, while the large pressure angle gear has a high bearing capacity. However, under the same transmission torque, the bearing load increases, so it is only used in special cases. And the tooth height of the gears has been standardized, usually using standard tooth heights. Modified gears have many advantages and have been widely used in various mechanical equipment. What materials are needed for gear customization and production in beach car gears, gear customization, and Zhejiang automotive gear manufacturers?

The material and heat treatment process of customized gear processing will have an impact on the load-bearing capacity, size, and weight of the gear. Before the 1950s, carbon steel was used for gears, alloy steel was used in the 1960s, and surface hardened steel was used in the 1970s.

According to the hardness of the tooth surface, gears can be divided into soft tooth surface and hard tooth surface. Gears with soft tooth surfaces have low load-bearing capacity, are easy to manufacture, and have good running in performance. They are mostly used in environments with low requirements. In the paired gears, the small wheel has a heavy load, so the hardness of the small wheel tooth surface is higher than that of the large wheel.

The cost of customized gear processing and manufacturing is relatively high. Some have special tooth profiles or high-precision gears, which require special or high-precision machine tools, tools, and measuring instruments, making the manufacturing process complex and costly. Low precision, transmission noise, vibration and impact, and environmental pollution. No overload protection effect.
