[0021] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0022] A conductive ring for oil-cooled shafts, such as Figures 1 to 4 As shown, it includes a conductive ring casting 1, which is a ring-shaped structure. An mounting ring 2 is fixedly connected to the inner wall of the conductive ring casting 1. The conductive ring casting 1 and the mounting ring 2 are integrally cast. The conductive ring casting 1 can be installed on the housing of the motor. The rotating shaft of the motor is located inside the conductive ring casting 1. The mounting ring 2 is equipped with equally spaced carbon fiber filaments 5, which transfer the static electricity of the shaft to the conductive ring casting 1 through the carbon fiber filaments 5. The carbon fiber filaments 5 are made of carbon fiber, and their tails are treated with impregnation such as glue and tin.

[0023] After the motor starts, the carbon fiber filament 5 is located in the annular groove of the motor rotating shaft. The static electricity generated by the rotating shaft after rotation is transmitted to the conductive ring casting 1 through the carbon fiber filament 5, and then transferred to the motor housing through the conductive ring casting 1.

[0024] The mounting ring 2 has connecting grooves 3 arranged at equal intervals. One end of the carbon fiber filament 5 is installed in the connecting groove 3, and the other end of the carbon fiber filament 5 faces the axis of the conductive ring casting 1.

[0025] An aluminum pressure block 4 is riveted to the carbon fiber filament 5 and welded into the connecting groove 3. When installing the carbon fiber filament 5, a riveting machine is needed to rivet the aluminum pressure block 4 onto the carbon fiber filament 5 and weld the aluminum pressure block 4 into the connecting groove 3 to complete the connection between the carbon fiber filament 5 and the conductive ring casting 1.

[0026] The conductive ring casting 1 is divided into two mounting cavities by the mounting ring 2. Both mounting cavities can be detachably installed with rubber oil baffles 7.

[0027] In this embodiment, the mounting ring 2 has a first mounting hole 9, and the rubber oil baffle 7 has a second mounting hole 12, which matches the first mounting hole 9. A locking nut 13 is installed in the second mounting hole 12, and one end of the locking nut 13 is threaded into the first mounting hole 9. The locking nut 13 is used to install the rubber oil baffle 7 on the mounting ring 2, which facilitates the replacement and cleaning of the rubber oil baffle 7.

[0028] The inner wall of the conductive ring casting 1 is fixedly connected with a positioning block 6, and a positioning groove 8 matched with the positioning block 6 is formed on the rubber oil baffle 7, so that the rubber oil baffle 7 is positioned through the positioning block 6 and the positioning groove 8, and workers can conveniently position and install the rubber oil baffle 7.

[0029] A spring mounting groove 10 is formed on the rubber oil baffle 7, and a lock spring 11 is mounted in the spring mounting groove 10, so that the lock spring 11 applies a pushing force to the rubber oil baffle 7, and the rubber oil baffle 7 is always attached to the motor rotating shaft, thereby preventing separation.
