Description

Technical Field

[0001] The utility model relates to the technical field of gear reducers, in particular to a split gear reducer. Background Art

[0002] Gear reducers are generally used in low-speed, high-torque transmission equipment. Ordinary motor 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. With the continuous development of the reducer industry, more and more companies are using reducers.

[0003] For example, the hypoid gear reducer with authorization announcement number "CN219639390U" is connected to the rod through a fixing ring. The fixing ring fixes the cylindrical rod to the surface of the fixed plate through the rod. The output end of the motor is fixed inside the cylindrical rod to drive the hypoid gear reducer. The motor contacts the contact plate, increasing the stability of the motor during operation. However, the drive gear and meshing gear of this reducer are fixed in size, and the reduction ratio of the reducer cannot be changed. There is only one reduction ratio, which makes it not widely used. Utility Model Content
