Description

Technical Field

[0001] The utility model belongs to the technical field of commutators and relates to a cleaning device, in particular to a commutator segment cleaning device of a commutator. Background Art

[0002] The commutator segments of a DC motor are connected to the rotor winding coils respectively. The commutator segments themselves are insulated from each other. When the motor is running, the carbon brushes rub against the commutator segments, producing some carbon powder, some of which will be deposited in the commutator segment grooves. If too much is deposited, the insulation between the commutator segments will be reduced due to the conductivity of the carbon powder, or even direct conduction between the commutator segments, which will affect the performance of the motor. In severe cases, sparks may occur, or even ring fires may form, seriously affecting the operation and performance of the motor. Therefore, when the motor is shut down, the commutator segments should be flushed, the surface dirt should be peeled off, the grooves of the commutator segments should be cleaned, and good insulation between the commutator segments should be maintained to lay a good foundation for the continuous operation of the motor in the next cycle.

[0003] A search revealed an energy-saving commutator segment cleaning machine disclosed in Chinese patent literature [Application Number: CN201721463843.0; Publication Number: CN207479098U]. This energy-saving commutator segment cleaning machine comprises: a base; a cleaning chassis located above the base, housing a cleaning basket with a rotary drive mechanism at the center of its bottom; a cleaning system comprising a heated water tank and a spray pipe, the heated water tank being equipped with a heater, through which liquid in the heated water tank enters the spray pipe via a high-pressure pump; a circulation system comprising a circulating pump and a sandwich located within the inner wall of the cleaning chassis; a drying device comprising an air duct located within the top of the cleaning chassis, the air duct being connected to an external blower; and a controller connecting and controlling the rotary drive mechanism, heater, high-pressure pump, circulating pump, solenoid valve, and blower. This energy-saving commutator segment cleaning machine boasts a simple structure and excellent cleaning performance. The circulation system allows waste liquid after cleaning to enter the sandwich, where the residual heat of the waste liquid is used to heat the cleaning chassis and simultaneously generate air, thereby increasing the drying rate and achieving energy conservation and environmental protection.

[0004] Although the spray pipe and heater disclosed in this patent can heat the cleaning chassis and dry the commutator segments, the device does not clean the grooves of the commutator segments. The spray pipe can only flush the commutator segments facing the spray pipe side, and flushing solely by the spray pipe will consume more cleaning agents and water, causing pollution and waste.
