Hardened gear reducers are widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical engineering, textile, printing and dyeing, pharmaceutical and other fields. Hardened gear reducer is a power transmission mechanism that utilizes a speed converter of gears to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. Hardened gear reducer refers to a gear reducer whose internal gear has a hardness>350HBS and whose large/small gears have undergone quenching or carburizing treatment. "It is a relatively precise machine that is used to reduce rotational speed and increase torque. It is suitable for environments where the rotational speed of high-speed shafts is not greater than 1500 rpm, the circumferential speed of gear transmission is not greater than 20 meters per second, and the operating ambient temperature is between - 40 ℃ and 45 ℃.".

The gears of the hardened gear reducer are made of high-strength low-carbon alloy steel through carburization and quenching, with high tooth surface hardness. The gears are all manufactured using CNC gear grinding technology, featuring high accuracy, good contact, high transmission efficiency, stable operation, and low noise; Small size, light weight, long service life, and high bearing capacity; Easy to disassemble and inspect, easy to install.

Its advantage lies in the fact that the design of the gear is carried out from two aspects, namely, the pressure on the tooth surface and the strength of the tooth root, which greatly enhances the hardness and accuracy of the gear. This can greatly reduce the weight of the reducer and make it more miniaturized. In addition, the performance of the reducer has also been greatly improved, and the transmission efficiency has been improved by one level. On the other hand, it greatly reduces the cost of maintenance and repair for users. With the continuous development of gear processing technology and the application of computer design, the development of world transmission technology tends to adopt hard tooth surface gear transmission.
