A reducer is an independent closed transmission device between the prime mover and the working machine, used to reduce speed and increase torque to meet work needs. In some cases, it is also used to increase speed, called a speed reducer. When selecting a reducer, it is necessary to compare the external dimensions, transmission efficiency, load-bearing capacity, quality, price, etc. of different types and varieties of reducers based on the selection conditions, technical parameters, performance of the power machine, economy, and other factors of the working machine, and choose the suitable reducer. A reducer is a relatively precise mechanical device used to reduce speed and increase torque.

1. The gears are made of high-strength low-carbon alloy steel through carburizing and quenching, with a tooth surface hardness of HRC58-62. The gears are all machined using CNC grinding technology, with high precision and good contact. 2. High transmission rate: single-stage greater than 96.5%, two-stage greater than 93%, three-stage greater than 90%. 3. Smooth operation and low noise. 4. Small size, light weight, long service life, and high load-bearing capacity. 5. Easy to disassemble and inspect, easy to install

A ring gear (A) is tightly connected to the gearbox housing, with a sun gear (B) driven by external power at the center of the ring teeth. Between the two, there is a set of planetary gear sets (C) consisting of three gears evenly divided and combined on a tray. The set of planetary gears relies on the output shaft, inner ring gear, and sun gear support to float during this period; When the input side power drives the sun gear, the planetary gearbox can drive the planetary gear to rotate and follow the trajectory of the inner ring gear to revolve around the center. The rotation of the planetary gear drives the output shaft connected to the tray to output power.
