FYK280‑280 hard tooth surface reducer shaft surface material and heat treatment process description

The core gear tooth surface of the FYK280-280 gear reducer is made of high-quality alloy steel as the basic material, and is equipped with mature carburizing and quenching, precision grinding and finishing processes. The hardness of the tooth surface after forming can reach HRC54-62. It has the advantages of high hardness, strong wear resistance, large load-bearing capacity, and long service life. It is a typical hard-tooth surface reducer that can meet the needs of stable transmission under heavy loads, high speeds, and continuous working conditions.

1. Description of core tooth surface materials

The hard tooth surface defines the performance characteristics of the gear and does not refer to a single steel grade. The FYK280-280 reducer gears are all made of industrial high-performance high-quality alloy steel, which is suitable for heavy-duty mechanical transmission conditions. The common mainstream steel grades in the industry are as follows:

1. 20CrMnTi alloy steel: the core material for heavy-duty gears in the industry, suitable for FYK280-280 normal working conditions. This steel has excellent comprehensive properties. After professional heat treatment, the tooth surface has high hardness, wear resistance and damage resistance. The gear core can retain good toughness and has outstanding impact load resistance, effectively avoiding gear damage caused by vibration and impact under working conditions.

2. 42CrMo alloy steel: high-end high-performance material, with better hardenability, strength and toughness than ordinary alloy steel. It is mostly used in heavy-load and high-intensity operation scenarios of FYK280-280 reducer. It is suitable for extreme loads and long-term continuous operation conditions, and the equipment has higher stability and durability.

2. Core heat treatment and processing technology

The hard tooth surface performance of the FYK280-280 reducer gear is mainly achieved by carburizing and quenching heat treatment process + precision grinding gear finishing process. The specific process principles and functions are as follows:

1. Carburizing and quenching heat treatment process: As the core process of gear surface hardening, low carbon alloy steel gears are placed in a carbon-rich medium for heating and insulation, so that carbon atoms can fully penetrate into the gear surface, and then are quenched and shaped. After the process is completed, the hardness of the gear surface can reach HRC54-62, which is extremely wear-resistant and anti-extrusion. The gear core still maintains high toughness, perfectly balancing high hardness and impact resistance, and is suitable for complex and changeable industrial transmission conditions.

2. Precision grinding gear finishing process: After heat treatment of gears, slight deformation will occur. Precision grinding and correction of the tooth surface and tooth shape through high-precision gear grinding equipment can improve the gear accuracy to level 6 high-precision standards. It effectively eliminates heat treatment deformation errors, optimizes gear meshing accuracy, ensures smooth transmission of the reducer and low operating noise, while further improving the tooth surface finish, reducing operating wear, and extending the service life of the equipment.

3. Summary

The tooth surface of the FYK280-280 hardened reducer is made of high-quality alloy structural steel as the base material. Through carburizing and quenching, it achieves a performance ratio of high hardness on the surface and high toughness on the core. It is matched with the precision grinding and finishing process to achieve high-precision, low-loss, and high-stable transmission effects. There will be slight differences in the material selection grades and process parameters of different manufacturers. If you need precise material parameters and process standards, you can consult the official technical manual of the corresponding brand or directly consult the manufacturer.
