The gearbox, in fact, is a power transmission mechanism, itself does not produce power, its role is to use different gear size and speed converter, the motor (motor) of the number of swings to their own number of swings, and get a larger torque of the body. Wouldn’t it be enough to adjust the speed of the motor? In fact, otherwise, the motor directly connected to the equipment, when the equipment is running, the motor load is very large, so the damage to the motor is also very large, and after the reducer is not the same, such as the deceleration ratio of 100 gearbox, the machine when running on the motor load is only one percent. Moreover, the gearbox is broken as long as the next gear change is good, the cost is much lower than the motor.
The gearbox is a relatively precise machine that is used to reduce speed and increase torque. It has a wide variety of models and different uses. According to the transmission type can be divided into gear reducer, worm worm reducer and planetary gear reducer, according to the transmission series can be divided into single-stage and multi-stage reducer.
In the current body for transmitting power and motion, the gearbox is widely used. The application of the reducer can be seen from the transmission work of large power to the transmission of small load and precise angle, and in industrial applications, the gearbox has the function of deceleration and increasing torque.
The main roles of the gearbox are:
1) Lower the speed at the same time to improve the output torque, torque output ratio according to the motor output by deceleration ratio, but pay attention not to exceed the rated torque of the reducer.
2) Slow down while reducing the inertia of the load.
