The gearbox is a device that realizes the shifting effect by the meshing of the large and small gears and is widely used in industrial automation. Generally, a large gear is mounted on the low-speed shaft of the gearbox, and a small gear is mounted on the high-speed shaft, and the acceleration or deceleration can be realized by the meshing and transmission between the gears. The step-down motor is a combination of a reducer and a stepping motor. This assembly body is also commonly referred to as a gear reduction motor or a gear reduction motor. It is an indispensable power device for mechanical equipment, especially in packaging machinery. Printing machinery, corrugated machinery, color box machinery, conveying machinery, food machinery, three-dimensional parking equipment, automatic warehousing, three-dimensional warehouse, chemical, textile, dyeing, and finishing equipment. Micro geared motors are also widely used in the fields of electronic locks, optical equipment, precision instruments, and financial equipment.
There are many types of gearboxes:
1. According to the type of transmission, it can be divided into a cylindrical gearbox, a planetary gearbox and a gearbox combined with each other;
2, according to the number of stages of the transmission can be divided into the single-stage gearbox and multi-stage gearbox;
3. According to the rotating arrangement, it can be divided into the expansion gearbox, split gearbox, and coaxial gearbox and hybrid gearbox.
l Reduce the speed and increase the output torque according to different reduction ratios
l Compact structure and small footprint
l High transmission efficiency and precise speed ratio
l The speed reduction reduces the inertia of the load at the same time, and the inertia decreases to the square of the reduction ratio.
l Provides more precise timing than chain systems, less friction loss, and less noise
