The principle of the reducer:
The purpose of deceleration by using various levels of gear transmission. The reducer is composed of pairs of gears at various levels. For example, the gear can be driven by a pinion to achieve a certain deceleration, and then through the multi-stage of this structure, the speed can be greatly reduced and the torque can be increased. .
Detailed description of the principle of the reducer:
When the output speed of the motor is input from the drive shaft, the small gear rotates, and the small gear drives the large gear to move. The gear of the large gear is larger than the small gear, and the speed of the large gear is slower than the speed of the small gear. It consists of the shaft of the large gear (output shaft ) Output, used as output deceleration.
The reducer is usually used in low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed power is transmitted through the gear on the input shaft of the reducer, so that the large gear on the output shaft is meshed to achieve the purpose of deceleration. The reducer will also have several pairs The same main gear to achieve the desired deceleration effect. The ratio of the number of teeth of the large gear and the small gear is the transmission ratio. (i.e. "Reduce the speed, increase the torque, reduce the inertia") The reducer is the power transmission mechanism, which uses the gear speed The converter decelerates the number of revolutions of the electric motor (motor) to the desired number of revolutions and obtains a large torque. In the current transmission power and motion mechanism, the application range of the reducer is very wide.
The role of the reducer
Reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the motor output and the reduction ratio, but be careful not to exceed the rated torque of the reducer.
Deceleration will also reduce the inertia of the load. The reduction in inertia is the square of the reduction ratio. You can see that the general motor has an inertia value.
Two, reducer speed ratio, speed ratio = motor output revolutions ÷ reducer output speed ("speed ratio" is also called "transmission ratio") three, reducer torque calculation formula, reducer torque = 9550 × motor power ÷ Motor power input revolution × reduction ratio × use efficiency (60%-96%)
