Description

Technical Field

[0001] This utility model relates to the field of motor carbon brushes, and in particular to a motor carbon brush sealing device. Background Technology

[0002] Motor carbon brushes are devices used on motor commutators or slip rings that slide in contact with the surface of rotating parts to transfer electrical energy. In DC motors, they work with the commutator to convert the DC power from the external circuit into the alternating current required by the internal windings of the motor, enabling the motor to rotate continuously. In AC motors, carbon brushes are mainly used to introduce or extract current into the rotor windings of wound-rotor motors to regulate the motor's performance.

[0003] Currently, when motor carbon brushes are installed inside the motor, a sealing and protective device is installed on the surface of the carbon brush to prevent oxidation and corrosion. However, the current sealing and protective device is fixed to the surface of the carbon brush in a fixed way. As the carbon brush wears down after continuous use, the fixed sealing and protective device will become unusable after the carbon brush wears down to the protective position.

[0004] Therefore, it is necessary to provide a motor carbon brush sealing device to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a motor carbon brush sealing device, which solves the problem that current sealing and protection devices are fixed to the surface of the carbon brush in a fixed way during use.

[0008] The protective component is disposed on the surface of the carbon brush body. The protective component includes a protective cover and a movable cover. The protective cover is fitted onto the surface of the carbon brush body, and the movable cover is disposed on the surface of the carbon brush body and located inside the protective cover.

[0009] The two propulsion components are respectively disposed between the protective cover and the movable cover.

[0010] Preferably, the surface of the movable cover is connected to a positioning block, and the inner wall of the protective cover is provided with a positioning groove that matches the positioning block.

[0011] Preferably, the pushing assembly includes a base, a fixed rod, a movable part, a connecting seat, a spring, and a stop, wherein the base is connected to the surface of the protective cover, and the fixed rod is connected to the surface of the base.

[0012] Preferably, the movable component is sleeved on the surface of the fixed rod, and the connecting seat is connected between the movable cover and the movable component.

A motor carbon brush sealing device includes:

[0029] Carbon brush body 1, protective component 2, and two actuating components 3;

[0030] The protective component 2 is disposed on the surface of the carbon brush body 1. The protective component 2 includes a protective cover 21 and a movable cover 22. The protective cover 21 is sleeved on the surface of the carbon brush body 1, and the movable cover 22 is disposed on the surface of the carbon brush body 1 and located inside the protective cover 21.

[0031] The two pushing components 3 are respectively disposed between the protective cover 21 and the movable cover 22.

[0032] The surface of the movable cover 22 is connected to a positioning block 23, and the inner wall of the protective cover 21 is provided with a positioning groove 24 that matches the positioning block 23.

[0034] The movable part 33 is sleeved on the surface of the fixed rod 32, and the connecting seat 34 is connected between the movable cover 22 and the movable part 33.

[0035] The spring 35 is sleeved on the surface of the fixed rod 32 and located below the movable member 33, and the stop block 36 is connected to the top of the fixed rod 32.

[0036] The use of spring 35 facilitates the reset of movable cover 22 inside protective cover 21 by moving movable part 33. Movable part 33 consists of movable sleeve and two movable rods.

When the movable cover 22 moves, it drives the positioning block 23 to move inside the positioning groove 24. When the movable cover 22 moves, it drives the movable part 33 to move on the surface of the fixed rod 32 through the connecting seat 34. When the movable part 33 moves on the surface of the fixed rod 32, it squeezes the spring 35 on the surface, which is then usable.
