What types of gear reducers are there?

Gear reducers are also called reducers and gear boxes. They are mainly composed of transmission motors and reducers. With the development of the industry, more and more gear reducers are used in various industries, mainly including cylindrical gear reducers, planetary gear reducers, parallel shaft gear reducers, micro gear reducers, harmonic gear reducers, worm gear reducers, etc. When choosing a gear reducer, in addition to considering the type, you should also pay attention to its material, speed ratio, power, torque and other important parameters. Let's learn about the types and parameters of gear reducers. 1. What are the types of gear reducers?
Gear reducers are a type of power transmission machinery that mainly uses the speed conversion of gears to reduce the number of revolutions of the motor to the desired number of revolutions and reduce inertia, and increase torque. They are generally used for low-speed and high-torque transmission equipment. There are many types of gear reducers, mainly the following:
1. Cylindrical gear reducer
Cylindrical gear reducer is a relatively precise machine with the advantages of high load capacity, low noise, long life, small size, high efficiency and light weight. Its purpose is to reduce the speed and increase the torque. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.
2. Planetary gear reducer
Planetary gear reducer is also called servo reducer. With the advantages of small size, high transmission efficiency, wide deceleration range and high precision, it is widely used in transmission systems such as servo motors, stepper motors, and DC motors. It can reduce the speed, increase the torque and reduce the rotational inertia ratio of the load motor under the premise of ensuring precise transmission. Planetary gear reducers are mostly used in construction, petroleum, ocean, shipbuilding, steel, non-ferrous metals, manufacturing, automobile transmission, smart home, electronic products, robot transmission and other fields.
3. Parallel shaft gear reducer
Parallel shaft helical gear reducer consists of two or three helical gears, adopts the unit structure modular design principle, and is widely used in light industry, food, beer and beverage, chemical industry, escalator, automated storage equipment, construction, machinery, steel metallurgy, papermaking, wood-based panel machinery, automobile manufacturing, water conservancy, printing and packaging, pharmaceuticals, textiles, building materials, logistics, feed machinery, environmental protection and other fields.
4. Micro gear reducer
Micro gear reducer, also known as micro reduction motor, is a reduction transmission mechanism that integrates micro motors and gear boxes to reduce speed and increase torque to meet the needs of mechanical equipment. Satellite gear reducers have the characteristics of small size, high torque, low noise, full speed ratio, stable performance, instantaneous conversion, high efficiency, energy saving and low heat generation. They are widely used in medical devices, smart homes, consumer electronics, automotive drives, robotics, aircraft, 5G communication equipment, logistics equipment, smart city equipment, smart medical equipment and other fields.
5. Harmonic gear reducer
The harmonic gear reducer consists of three parts: a fixed internal gear rigid wheel, a flexible wheel, and a wave generator that causes radial deformation of the flexible wheel. It uses flexible gears to generate controllable elastic deformation waves, causing the teeth of the rigid wheel and the flexible wheel to be relatively staggered to transmit power and motion. Harmonic gear reducers have the advantages of high precision, high load-bearing capacity and small size. They are increasingly widely used in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, common military equipment, machine tools, instruments, electronic equipment, mining and metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery and medical equipment.
6. Worm gear reducer
Worm gear reducer is a power transmission mechanism, which is mostly used in the mechanism of transmitting power and motion. It is widely used in docks, mining, transportation, lifting, construction, petroleum, ocean, shipbuilding, steel, non-ferrous metals and other fields.
2. What are the important parameters of gear reducer
When choosing a gear reducer, it is necessary to refer to the parameters of the gear reducer in detail and choose the appropriate product according to actual needs. The parameters that need to be considered are mainly:
1. Material
The core gear material of the gear reducer needs to be selected according to the purpose and scene. Commonly used materials include metal materials and plastic materials.
2. Speed ​​ratio
The speed ratio of the gear reducer includes the reduction ratio and transmission ratio, among which the reduction ratio determines the output speed and torque value; the calculation formula of the reduction ratio is: reduction ratio = input speed ÷ output speed.
3. Power
Power includes important parameters such as output speed, torque, current, etc., which are also parameters that need to be considered and calculated. The calculation formula is as follows: Motor power = torque ÷ 9550 × motor power input speed ÷ speed ratio ÷ usage coefficient
4. Torque
Torque is also called moment, which is determined by the reduction ratio. When selecting, you need to calculate the magnitude of the torque. The calculation formula is as follows: Reducer torque = 9550 × motor power ÷ motor power input speed × speed ratio × usage coefficient.
