Abstract
A gear motor includes an electric motor adapted to drive a transmission. A bearing flange of the transmission is secured to a housing part of the transmission. A bearing for rotatably mounting the output shaft of the transmission is accommodated in the bearing flange, and a shaft sealing ring is accommodated in the bearing flange, which seals towards the shaft, e.g., performing a sealing function. A cover disc is secured, e.g., using screws, to the bearing flange on the side of the bearing flange facing away from the interior of the transmission, the interior, for example, being filled with lubricating oil. The cover disc has continuous grooves extending in the circumferential direction on its side facing the bearing flange, and a radial borehole is formed in the cover disc and feeds into one of the grooves, e.g., into the radially outermost groove.
