The vertical motor is vertically arranged on the driven machine, and the motor shaft also vertically drives the machine. It is widely used in industrial production, such as on vertical water pumps and vertical lathes.

[0003] A vertical motor is disclosed in Chinese Patent CN206442220U. This patent discloses a technical solution for convenient installation, which solves the problem that the rotating shaft of the existing motor needs to bear bidirectional thrust. In order to reduce the axial movement of the motor, two angular contact ball bearings need to be installed at the non-driving end or the driving end of the motor. The two angular contact ball bearings are installed in opposite directions, and the installation is very inconvenient, and the angular contact ball bearings are easy to be damaged.

[0004] When the device is in use and the motor is placed without being used, the shaft extension end of the motor is exposed, which easily causes the shaft extension end of the motor to contact the external air, making it easy for water and impurities to stay on the outer peripheral wall of the shaft extension end of the motor, thereby damaging the outer peripheral wall of the shaft extension end of the motor and reducing the use effect. Therefore, a waterproof and dustproof device for the shaft extension end of a vertical motor is proposed to solve the above problems. Content of the Utility Model
