<p>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.</p>

<p><strong>There are many types of gearboxes:</strong></p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>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;</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>2, according to the number of stages of the transmission can be divided into the single-stage gearbox and multi-stage gearbox;</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>3. According to the rotating arrangement, it can be divided into the expansion gearbox, split gearbox, and coaxial gearbox and hybrid gearbox.</p>

<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>l  Reduce the speed and increase the output torque according to different reduction ratios</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>l  Compact structure and small footprint</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>l  High transmission efficiency and precise speed ratio</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>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.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>l  Provides more precise timing than chain systems, less friction loss, and less noise</p>
