Gear reducer is a kind of power transmission machinery, which mainly uses the speed conversion of gears to slow down the number of revolutions of the motor to the required number of revolutions, reduce inertia and improve torque. Generally used for low-speed and high-torque transmission equipment. There are many kinds of gear reducers, mainly the following:
1, cylindrical gear reducer
Cylindrical gear reducer is a relatively precise machine, which has the advantages of high bearing capacity, low noise, long life, small volume, high efficiency and light weight. The purpose of use is to reduce the rotation speed and increase the torque, which is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmacy and other fields.
2. Planetary gear reducer
Planetary gear reducer is also called servo reducer. It has the advantages of small size, high transmission efficiency, wide deceleration range and high precision. It is widely used in servo motors, stepping motors, DC motors and other transmission systems. On the premise of ensuring accurate transmission, it can reduce speed, increase torque and reduce the moment of inertia ratio of load motors. Planetary gear reducers are mostly used in construction, petroleum, ocean, shipbuilding, steel, nonferrous metals, manufacturing, automobile transmission, smart home, electronic products, robot transmission and other fields.
3, parallel shaft gear reducer
Parallel-axis helical gear reduction is composed of two or three-stage helical gears, and adopts the modular design principle of unit structure, which is widely used in light industry, food, beer and beverage, chemical industry, escalator, automatic storage equipment, construction, machinery, steel metallurgy, paper making, wood-based panel machinery, automobile manufacturing, water conservancy, printing and packaging, pharmacy, textile, building materials, logistics, feed machinery, environmental protection and other fields.
4. Miniature gear reducer
Micro-gear reducer, also known as micro-gear motor, is a kind of deceleration transmission mechanism integrating micro-motor and gearbox, which is used to reduce the speed and increase the torque to meet the needs of mechanical equipment. Satellite gear reducer has the characteristics of small size, large torque, low noise, complete speed ratio, stable performance, instantaneous conversion, high efficiency and energy saving, low calorific value and so on, and is widely used in medical equipment, smart home, consumer electronics, automobile driving, robots, airplanes, 5G communication equipment, logistics equipment, smart city equipment, smart medical equipment and other fields.
5. Harmonic gear reducer
The harmonic gear reducer consists of a rigid wheel with fixed internal teeth, a flexible wheel and a wave generator that radially deforms the flexible wheel. The flexible wheel is used to generate controllable elastic deformation waves, so that the teeth of the rigid wheel and the flexible wheel are relatively staggered to transmit power and motion. Harmonic gear reducer has the advantages of high precision, large bearing capacity and small size, and is widely used in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, general ordnance, machine tools, instruments, electronic equipment, mining metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery and medical equipment.
6. Worm gear reducer
Worm gear reducer is a kind of power transmission mechanism, which is mostly used to transmit power and movement. It is widely used in dock, mine, transportation, lifting, construction, petroleum, ocean, ship, steel, nonferrous metals and other fields.
2. What are the important parameters of the 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 the actual demand. The parameters to be considered mainly include:
1 material
The core gear material of gear reducer needs to be selected according to the purpose and scene. The commonly used materials are metal materials and plastic materials.
2. Speed ratio
The speed ratio of gear reducer includes reduction ratio and transmission ratio, in which the reduction ratio determines the output speed and torque; The calculation formula of reduction ratio is: reduction ratio = input speed ÷ output speed.
3. Strength
Power includes output speed, torque, current and other important parameters. This is also a key parameter to be considered and calculated. The calculation formula is as follows: motor power = torque ÷9550× motor power input revolutions ÷ speed ratio ÷ service coefficient.
4. Torque
Torque, also known as torque, is determined by the reduction ratio and needs to be calculated when choosing. The calculation formula is as follows: reducer torque =9550× motor power ÷ motor power input revolutions × speed ratio × service factor.
