Starred- River gearbox (hereinafter referred to as gearbox ) is a power transmission mechanism, the use of gear speed converter, the number of motor rotations reduced to the desired number of rotations, and get a larger torque mechanism.
Parallel Shaft Helical Gearbox
The function of gearbox is:
1. Decrease the speed and increase the output torque at the same time. The ratio of output torque is multiplied and decelerated by the motor output, but it should not exceed the rated torque of the reducer.
2. Speed reduces the inertia of the load at the same time, and the reduction of inertia is the square of the reduction ratio. You can see that the general motors have an inertia value.
Types of gearbox:
The general reducer has helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer and so on), planetary gear reducer, cycloid pinwheel reducer, worm gear reducer, planetary friction type mechanical stepless transmission and so on.
Types of common reducer:
1. The main characteristic of worm gear and worm reducer is that it has the function of reverse self-locking. It can have a large reduction ratio. The input shaft and the output shaft are not on the same axis, nor on the same plane. But the general volume is large, the transmission efficiency is not high, and the accuracy is not high.
2. Harmonic drive of harmonic reducer transfers motion and power by means of controllable elastic deformation of flexible components. It has small volume and high precision, but its disadvantages are that flexible wheel has limited service life, can not resist impact, and its rigidity is worse than metal parts. The input speed should not be too high.
3. The advantages of planetary reducer are compact structure, small return clearance, high precision, long service life, rated output torque can be done greatly. But the price is a little expensive.
Gearbox is a mechanical transmission device in many fields of national economy. The product categories involved in the industry include all kinds of gear reducer, planetary gear reducer and worm gear reducer, as well as all kinds of special transmission devices, such as speed-increasing device, speed-regulating device, and all kinds of composite transmission devices including flexible transmission device. Wait. Products and services in the field of metallurgy, non-ferrous, coal, building materials, shipping, water conservancy, power, construction machinery and petrochemical industries.
