Uncover the mystery of reducer: detailed interpretation—R/F/S/K SERIES GEARBOX, NMRV GEARBOX

Reducer is one of the most widely used mechanical transmission devices in modern industry. Its main function is to reduce the speed of high-speed rotating shaft and transfer the torque output. It is not only widely used in a variety of machinery manufacturing equipment, but also in energy, light industry, mining and metallurgy and other fields are increasingly widely used. In practical application, the reducer has an important role, there are some more important parts and components of the structure, let’s break down its mystery one by one, read the principle and structure of the reducer in detail.

1. Working principle of reducer

Reducer mainly through the input of high-speed rotating power, through the internal gear structure will be converted into low speed and high torque output power. The gear is the core part of the reducer. Different types of reducer gear structure is different, can be divided into planetary gear, hard tooth gear, worm gear and bevel gear reducer, different gear structure is suitable for different working conditions, each has advantages and disadvantages. For example, planetary gear reducer is suitable for small motor, small volume, high transmission efficiency; The hard tooth face gear reducer has simple structure and is suitable for large machinery.

2. Reducer parts

The reducer is composed of a transmission part and an auxiliary part. The transmission part includes input shaft, gear, output shaft and bearing. The auxiliary parts include cover plate, seal, cooling system and gear box. The various parts of the reducer are made of different materials to ensure the safety, reliability and long life of the reducer. For example, the gear material is usually made of alloy steel with high strength and rigidity to ensure its load-bearing and transmission capacity; The gear shaft materials are made of high quality carbon steel or alloy steel, which is guaranteed in strength and toughness.

3. Composition and structure of reducer

Different types of reducers have different structures, but the principle of slowing down the equipment speed and improving the torque output is the same. A standard reducer is mainly composed of gear plate, input shaft, gear shaft, output shaft, bearing, inner CAM, outer CAM and so on. Among them, the input shaft and the output shaft are the motion shaft of the whole reducer, the input shaft is the motor shaft of high speed movement, the gear shaft and the output shaft are connected through the gear drive, so as to realize the output of low speed and large torque. And inside the reducer, there are some important parts that affect the quality and service life of the reducer, such as springs, bearings and so on.

4. Maintenance of reducer

Reducer as a mechanical transmission device, maintenance is very important. Reasonable maintenance can improve the life of the reducer, reduce the failure rate, and ensure its normal operation. Generally speaking, the reducer maintenance mainly includes cleaning, lubrication and adjustment work. In the cleaning of the reducer, in addition to removing the dirt and debris on the surface, but also need to remove the internal dirt and rust oil. The lubricating work of reducer mainly uses lubricating oil or grease. The quality of lubricating oil should meet the specified requirements for use. Before use, oil quantity and replacement cycle must be checked and decided. The use of grease should be adjusted according to the actual situation. In addition, the reducer in the process of use also need to carry out the necessary adjustment and maintenance, in order to ensure its normal operation.
