Motor waterproof structure

Abstract

The invention discloses a motor waterproof structure. The motor waterproof structure comprises a motor enclosure, wherein a rotor shaft is arranged in the motor enclosure and extends out of an end cover, a cover shell is fixedly arranged outside the end cover, a plastic seat is fixedly arranged in the cover shell and outside a tail end of the rotor shaft, a central cavity is formed in the plastic seat and is used for accommodating the tail end of the rotor shaft, a through hole is formed in a part, corresponding to the central cavity, of the cover shell, and a rubber plug is detachably assembled in the through hole and is in close contact with an end surface of the plastic seat. By the abovementioned motor waterproof structure, dual driving of manual driving and power driving can be achieved, the rotor shaft of a motor is prevented from being collided, the corrosion resistance of the rotor shaft of the motor is protected, water drop is prevented from entering the motor, and a relatively good waterproof effect is achieved. The motor waterproof structure is simple and is convenient to use, moreover, power consumption is reduced, and the safety and the reliability are improved.

Description

technical field [0001] The invention relates to a motor, in particular to a motor waterproof structure. Background technique [0002] In the transmission process of the motor with reducer, both electric function and manual function are required. In the past, the tail of the rotor shaft is usually exposed outside the casing, and the seal between the rotor shaft and the casing is sealed by a sealing ring. This kind of sealing structure has the following disadvantages in the specific application process: [0003] 1) Since the rotor shaft is exposed, it is easy to be corroded and easily damaged by bumps; [0004] 2) The rotor shaft is a moving part, while the casing is a stationary part, and the sealing ring between them will increase the rotation resistance of the motor and increase the power consumption; [0005] 3) There is no way to deal with the condensation caused by water vapor inside the casing. In severe cases, it may cause a short circuit between live parts and caus...
