Gear reducer motor working principle
Gear reducer structure
Gear reducer structure consists of drive shaft, multi-stage gear (two gears for one section), bearing, gear box (casing, usually aluminum alloy or cast iron) bracket, motor and other main parts.
Gear reducer transmission principle
Gear reducers are gear trains that reduce the speed, increase the torque, and reduce the inertia. The working principle is that the motor (driver) provides the rotation speed, the motor rotation speed is very high (usually 4 levels 1720rpm, 6 level 1150), but the torque is very small, then a speed reducer is needed to reduce the speed and increase the load capacity; the motor power is transmitted through the gear reducer The principle of the mutual conversion of gears is to mesh the pinion with a small number of teeth on the large gear with a large number of teeth on the output shaft to achieve the purpose of reducing the rotational speed and increasing the torque. Now the common speed reducer also uses the same principle to achieve the desired deceleration effect on several pairs of gears. The corresponding one is the speed increaser. The principle is the opposite of the effect. The ratio of the number of teeth of the large gear and the small gear is ours. Often referred to as the gear ratio (reduction ratio REDUCTION RATIO).
Gear reducer is divided into coaxial, two-stage cylindrical
The coaxial gear motor has the advantages of compact structure, small size, attractive appearance, strong ability to withstand overload, etc., fine reduction ratio classification, wide selection range, low energy consumption, superior performance, and high efficiency of reducer (up to 95%). Small vibration, low noise and so on.
Gear reducer lubrication
The rotation of the gears and the operation of the bearings require lubrication oil to reduce the friction between the gears. A good lubrication oil machine gearbox body design can effectively reduce the thermal energy during running friction. The proper design of the lubrication system can increase the service life of the reducer and improve the efficiency of the reducer.
Gear reducer commonly used lubricating oil is divided into grease (Grease) and extreme pressure gear oil (such as HD220, HD320, HD460).
