DC motor output shaft end waterproof device

Abstract

The invention discloses a DC motor output shaft end waterproof device, which comprises a waterproof outer shell, wherein a horizontally-arranged base is fixed on the inner wall of one side of the bottom end of the waterproof outer shell, a motor is fixed at the top end of the base, an output shaft of the motor is connected with a horizontally-arranged rotating shaft, a communicated connecting groove is formed in the side wall of one side, away from the motor, of the waterproof outer shell, one end, away from the motor, of the rotating shaft extends to the outside of the waterproof outer shellafter penetrating the connecting groove, a vertically-arranged fixing base is fixed on the side wall of one side, close to the connecting groove, of the rotating shaft, the fixing base is slidably connected on the inner wall of the waterproof outer shell, an annular accommodating groove is formed in the side wall of one side, close to the connecting groove, of the fixing base, and a vertically-arranged first guide ring is fixed on the side wall of one side, away from the connecting groove, in the accommodating groove. The DC motor output shaft end waterproof device can realize multi-stage waterproof effect on an output shaft end of a motor, prevents the normal use of the motor from being affected due to damages to the motor caused by infiltration of external water, has good waterproof effect and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of DC motors, in particular to a waterproof device for output shaft ends of DC motors. Background technique [0002] scene technology [0003] A DC motor is a rotating electrical machine that converts DC electrical energy into mechanical energy (DC motor) or converts mechanical energy into DC electrical energy (DC generator). It is a motor that can convert DC electric energy and mechanical energy into each other. When it operates as a motor, it is a DC motor, which converts electrical energy into mechanical energy; when it operates as a generator, it is a DC generator, which converts mechanical energy into electrical energy. Since the output shaft of the motor extends from the motor case, external water can easily seep into the motor from the connection, which can easily cause damage to the motor and affect the normal use of the motor. Therefore, we propose a waterproof device for the output shaft end of t...
