Description

Waterproof structure of motor rotating shaft Technical Field The invention relates to the technical field of motor rotating shafts, in particular to a waterproof structure of a motor rotating shaft. Background The motor is an electromagnetic device for converting or transmitting electric energy according to the law of electromagnetic induction, and has the main function of generating driving torque as a power source of an electric appliance or various machines, and a motor rotating shaft matched with the motor is an output end of the motor and is used for power connection and transmission of the motor. The current motor rotating shaft is used according to the specification of the motor in a matching way, the length of the motor rotating shaft is insufficient due to the problem of the installation position when the motor rotating shaft is used, the rotating shaft with enough length needs to be customized, so that the use cost is increased, meanwhile, the sealing of the current motor rotating shaft is sealed through a simple sealing bearing, the sealing waterproof effect after long-time use can be continuously reduced, the motor is damaged due to water inflow inside the motor, the rotating shaft needs to be lubricated by lubricating oil when rotating at a high speed, the rotating oil continuously reduces in a long-time manner, the consumption is extremely fast, the friction force of the rotating shaft is increased, the service life of the rotating shaft is reduced, and therefore, the waterproof structure of the motor rotating shaft is provided.
