Abstract
A housing for a plastic gearbox and associated plastic gearbox and a robot. The housing includes a body including an inner engaging portion circumferentially arranged on an inner surface of the body, the inner engaging portion adapted to be engaged with a transmission assembly of the plastic gearbox; and an adjusting mechanism arranged around the body and operable to squeeze the body inwardly to reduce an inner diameter of the body. By using the adjusting mechanism to squeeze the body of the housing inwardly, the fit error between the inner engaging portion and the transmission assembly can be compensated in an efficient way. Furthermore, the adjusting mechanism is a part of the housing and thus the body of the housing which is made of plastic does not need to be too thick, which makes injection molding easier and manufacturing precision improved.
