The position of the reducer in the national economy is becoming more and more important, and there are more and more types of products.The common reducer types are gear reducer, worm reducer, harmonic reducer, planetary reducer and cycloid reducer.Among the many reducers, how to choose the reducer that meets your requirements?After reading it, you will understand what kind of reducer to buy? 1. Gear reducer The gear reducer is designed and manufactured on the basis of the modular combination system.There are many kinds of motor combinations, installation forms and structural schemes.The transmission ratio has been carefully graded to meet different conditions of use and realize mechatronics.The gear reducer has the characteristics of small size, light weight, long service life, high bearing capacity, large transmission torque, convenient disassembly and maintenance, convenient installation, stable operation, and low noise.The gear reducer has high transmission efficiency, low energy consumption and superior performance. 2. Worm gear reducer The worm gear reducer is a power transmission mechanism that uses a speed converter of gears to reduce the number of revolutions of the electric motor (electric motor) to the required number of revolutions and obtain a larger torque.The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio.The input shaft and output shaft are not on the same axis or plane.However, the volume is generally large, the transmission efficiency is not high, and the accuracy is not high. 2. Harmonic reducer Harmonic gear reducer is a kind of gear reducer.It uses flexible gears to generate controllable elastic deformation waves, so that the teeth of the rigid and flexible gears are relatively staggered to transmit power and motion.It consists of a fixed internally toothed rigid wheel, a flexspline and a wave generator that causes radial deformation of the flexspline.Harmonic gear reducer is a new type of transmission structure in gear reducer.This kind of transmission is essentially different from general gear transmission, and has its particularity in meshing theory, group calculation and structural design. The harmonic drive of the harmonic reducer uses the controllable elastic deformation of the flexible element to transmit motion and power.It has the characteristics of small size, high precision and high carrying capacity.Compared with ordinary reducers, its volume and weight are reduced by at least 1/3 due to a 50% reduction in material usage.But the disadvantage is that the flexible wheel has limited service life, is not resistant to impact, and has poor rigidity compared with metal parts.The input speed cannot be too high. 4. Planetary reducer The planetary reducer has the advantages of small size, compact structure, light weight, small return clearance, high precision, high bearing capacity, long service life, stable operation, low noise, large transmission ratio range, large output torque, large speed ratio, and high efficiency. and safety performance.The main transmission structure of the planetary reducer is: planetary gear, sun gear and ring gear.The internal gear of the planetary reducer is carburized, quenched and ground with 20CrMnTi.The planetary reducer has the characteristics of power splitting and multi-tooth meshing.It is a new type of reducer with wide versatility.The input power can reach 104kw.The disadvantage is that the price is slightly expensive. 5. Cycloidal pinwheel reducer Cycloidal pin gear reducer is a transmission model based on the principle of cycloid pin gear meshing planetary transmission.It is an ideal transmission device.Its advantages are many, it is versatile and can be used both forward and backward.It can achieve a high reduction ratio of 1:87 and a high-efficiency single-stage transmission of more than 90%.If a multi-stage transmission is used, the reduction ratio is larger.The reduction ratio of one-stage transmission is 9-87, the reduction ratio of double transmission is 121-5133, and the multi-stage combination can reach tens of thousands.Moreover, the pin-tooth meshing system has sleeve rolling friction, the meshing surface has no relative sliding, and the deceleration efficiency reaches 94%.
