[0002] With the continuous advancement of automobile technology, more and more related equipment have emerged. Among them, reducers are generally used for low-speed and high-torque transmission equipment. The power of electric motors, internal combustion engines or other high-speed running engines is decelerated by meshing the gear with fewer teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

[0003] Existing vehicle-mounted reduction gears, due to their stability, are often integrated, fixed, and welded. During maintenance and installation, the reduction gears require removal of the outer casing, which is difficult to disassemble. This process can damage the internal gears, increasing maintenance costs. This has become a pressing issue for those skilled in the art. Utility Model Content
