Gear reducer is a power transmission machinery, mainly using the speed conversion of gears, the number of motor rotation will be slowed down to the desired number of rotary and reduce inertia, and enhance the torque, generally used for low-speed high-torque transmission equipment, the gear reducer types are numerous, there are mainly the following kinds:
1, cylindrical gear reducer
Cylindrical gear reducer is a relatively precise machinery, has the advantages of high bearing capacity, low noise, long life, small size, high efficiency, light weight, etc. The purpose of using it is to reduce the rotational speed and increase the torque, which is widely used in the fields of metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceuticals and so on.
2, planetary gear reducer
Planetary gear reducer, also known as servo reducer. With the advantages of small size, high transmission efficiency, wide range of deceleration, precision and so on, it is widely used in servo motors, stepper motors, DC motors and other transmission systems, which can reduce the speed, increase the torque, and reduce the inertia ratio of the loaded motor under the premise of guaranteeing precision transmission. Planetary gear reducer is mostly used in construction, oil, marine, ship, steel, non-ferrous metal, 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 stages of helical gears, the use of unit structure modular design principle, widely used in light industry, food, beer and beverage, chemical industry, escalators, automated warehousing equipment, construction, machinery, iron and steel metallurgy, papermaking, man-made board machinery, automobile manufacturing, water conservancy, printing and packaging, pharmaceutical, textile, building materials, logistics, feed machinery, environmental protection and other fields.
4, micro gear reducer
Micro gear reducer, also known as micro gear motor, is a micro motor and gear box for the integrated assembly of the speed reduction transmission mechanism, used to reduce the rotational speed and increase the torque to meet the needs of mechanical equipment work. Featuring small size, high torque, low noise, full speed ratio, stable performance, instantaneous conversion, high efficiency, power saving and low heat generation, satellite gearmotors are widely used in the fields of medical equipment, smart home, consumer electronics, automotive drive, robotics field, aircraft field, 5G communication equipment, logistics equipment, smart city equipment, smart medical equipment, and so on.
5. Harmonic Gear Reducer
Harmonic Gear Reducer consists of three parts: a fixed internal tooth rigid wheel, a flexible wheel, and a wave generator that deforms the radial direction of the flexible wheel. It utilizes flexible gears to generate controllable elastic deformation waves, which cause relative misalignments between the teeth of the rigid wheel and the flexible wheel, to transfer the power and motion. Harmonic gear reducer has the advantages of high precision, high bearing capacity, small volume, etc., in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, common ordnance, machine tools, instrumentation, electronic equipment, mining and metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery, as well as medical equipment and so on, is getting more and more widely used.
6, worm gear reducer
Worm gear reducer is a kind of power transmission mechanism, mostly used in the transmission of power and movement in the agency, widely used in dock, mining, transportation, lifting, construction, petroleum, marine, shipbuilding, iron and steel, non-ferrous metals and other fields.
Second, what are the important parameters of the gear reducer
When choosing a gear reducer, you need to refer to the parameters of the gear reducer in detail and choose the right product according to the actual needs of the parameters to be considered are:
1, the material
The core gear material of the gear reducer needs to be selected according to the use, the scene to the needs of the commonly used are Metal material, plastic material and so on.
2, speed ratio
The speed ratio of the gear reducer includes the reduction ratio and transmission ratio, in which the reduction ratio determines the value of the output speed and torque; the formula of the reduction ratio is: reduction ratio = input speed ÷ output speed.
3, power
Power contains output speed, torque, current and other important parameters, but also need to focus on the consideration and calculation of the parameters, the formula is as follows: motor power = torque ÷ 9550 × motor power input revolutions ÷ speed ratio ÷ coefficient of use.
4, torque
Torque is also known as torque, determined by the reduction ratio, the choice needs to calculate the size of the torque, the formula is as follows: reducer torque = 9550 × motor power ÷ motor power input revolutions ÷ speed ratio ÷ coefficient of use.
