Introduction to the characteristics of common geared motors

Shenzhen Penghui Technology Co.,Ltd | Updated: Oct 31, 2018

The gear reduction motor has a wide range of applications, simple structure and easy precision, and the gear teeth can be made into straight teeth, helical teeth and herringbone teeth. The worm gear motor has a compact structure, a large transmission ratio, stable operation and low noise, but the efficiency is relatively low. The worm-gear reducer has gear transmission in the high-speed stage and the worm drive in the high-speed stage. The former has a compact structure and the latter has high transmission efficiency.

 

The planetary gear transmission of the planetary gear motor effectively utilizes the power splitting and the coaxiality of the input and output, and the proper use of the internal meshing. Therefore, compared with the conventional fixed-shaft gear transmission, the planetary geared motor has small mass and small volume. The transmission ratio is large, the bearing capacity is large, the transmission is smooth and the transmission efficiency is high. Due to these characteristics, planetary gear motor is widely used in metallurgy, mining, construction, aviation and other mechanical fields.

 

The cycloid reducer motor adopts the principle of planetary gear transmission with less teeth difference. The transmission process is to install a double eccentric sleeve with a 180 degree misalignment on the input shaft, and two roller bearings called a jib are mounted on the eccentric sleeve. The H mechanism is formed, and the center hole of the two cycloidal wheels is an eccentric sleeve, and the raceway of the arm bearing is uploaded, and the cycloidal wheel and the needle gear are meshed to form an internal meshing speed reduction mechanism with a difference of one tooth. Harmonic gear transmission is the abbreviation of harmonic gear planetary transmission. Harmonic gear reduction motor transmission is a kind of planetary gear with less tooth difference. It is usually composed of rigid cylindrical gear, flexible cylindrical gear, wave generator and flexible bearing.
