Basic knowledge of gearbox

Today, in order to help everyone better use this machine equipment, the editor will now introduce some basic knowledge about it:

1. What is a gearbox?

A reducer is a power transmission mechanism that uses a speed converter of gears to reduce the rotational speed of a motor to the desired rotational speed, thereby obtaining a larger torque for the machine equipment.

2. The function of this device

1. Reduce speed while increasing output torque, and the torque output ratio should be calculated by multiplying the motor output by the reduction ratio - but be careful not to exceed the rated torque of the reducer.
2. Deceleration simultaneously reduces the inertia of the load, and the decrease in inertia is the square of the reduction ratio. Generally speaking, most motors have an inertia value.

2. Types of equipment

General reducers include helical gears (including parallel axis helical gears, worm gear reducers, bevel gears, etc.), planetary gear reducers, cycloidal pinwheel reducers, worm gears, and planetary friction type mechanical continuously variable transmissions, among others.

3. Common types of reducers

1. The main feature of worm gear reduction equipment is its reverse self-locking function, which can have a large reduction ratio and the input shaft and output shaft are not on the same axis or plane; However, it generally has a large volume, low transmission efficiency, and low accuracy.
2. The harmonic drive of harmonic reducer utilizes the controllable elastic deformation of flexible components to transmit motion and power. It has a small volume and high accuracy, but the disadvantage is that the flexible wheel has a limited service life and is not resistant to impact. Its rigidity is poor compared to metal parts - when using it, attention should be paid to its input speed not being too high.
3. The advantages of planetary gearboxes are compact structure, small return clearance, high precision, and long service life, so the rated output torque can be made very large - although its price is slightly higher.
