Problems solved by technology

In the past period of time, in the mechanical power transmission equipment, the AC motor drives the reducer through various forms of couplings. When the three are connected in pairs, they need to be fixed with keys, interference fits, etc., so that the axial distance Elongated, more types of parts, lower system reliability, and cause shaft alignment errors, resulting in wear and tear of the transmission mechanism, and the mechanism is prone to jamming

[0003] Usually the cycloidal pinwheel transmission drives the needle wheel pair through the eccentric shaft concentric with the motor shaft, and the double-row planetary gear drives the output shaft to rotate through the planet carrier with straight pins. In severe cases, the bearing will be scrapped ahead of time, and its transmission mechanism can only bear radial loads. The rotation axis must be parallel to the horizontal line during installation, which restricts engineering applications where the axis of the wall-mounted type and the top-mounted type are at a certain angle to the horizontal line.
