Problems solved by technology

Due to the continuous wear of the carbon brush during long-term operation, the pressure of the carbon brush is not enough or the collector ring is not round, and oil droplets or other debris on the bearing fall between the commutation ring and the carbon brush. And so on a variety of situations, will cause the carbon brush to emit sparks
If the spark phenomenon is not dealt with in time, the spark will become bigger and bigger, and then burn the carbon brush and commutator, causing the excitation circuit to be interrupted and the brush holder to be burned

specific Embodiment approach 1

[0036] Such as Figure 1-15As shown, a safety anti-spark motor includes a motor 1, a mounting base 2, a matching base 3, a carbon brush mounting shell 4, a loading and unloading device 5, a shock absorbing member 6, a protective shell 7, an auxiliary trimmer 8 and cleaning device 9, the right end of the motor 1 is fixedly connected with an installation carrier 2, the right end of the installation carrier 2 is fixedly connected with a matching carrier 3, and the front and rear sides of the right end of the matching carrier 3 are fixedly connected with a carbon brush installation shell 4, The two carbon brush mounting shells 4 are fixedly connected with loaders 5, and there are four shock absorbing members 6, one end of the four shock absorbing members 6 is respectively fixedly connected to the four end faces of the motor 1 in the circumferential direction, and the protective shell 7 The four end faces in the circumferential direction of the inner end are respectively fixedly co...

specific Embodiment approach 2

[0038] Such as Figure 1-15 As shown, the motor 1 includes an inner shell 1-1, a stator 1-2, a rotor 1-3, an output shaft 1-4 and a commutation ring 1-5, and the commutation ring 1-5 is arranged on the output shaft 1-4 the right end of . The internal structure of the motor will not be described in detail, and it is not the innovation of the present invention. The fixed connection between the inner shell 1-1 and the main body 2-1 of the mounting base can be welded.

specific Embodiment approach 3

[0040] Such as Figure 1-15 As shown, the installation carrier 2 includes the installation carrier main body 2-1 and the connecting pipe 2-2, and the four corners of the right end of the installation carrier main body 2-1 are fixedly connected with the connecting pipe 2-2; The main body 2-1 is fixedly connected to the right end of the inner casing 1-1. When it is necessary to overhaul the carbon brush or its related components, the installation carrier 2 does not need to be disassembled, only the matching carrier 3 is removed from the installation carrier 2, and the installation carrier 2 is used as the inner shell 1-1 and Cooperating with the medium connected to the carrier body 3-1, it is convenient to disassemble and assemble the carrier body 3-1, and then unload the carbon brush and other related components together, and it is convenient to install and load the carrier body 3-1 after maintenance The seat 2 is reinstalled on the inner shell 1-1.

Abstract

The invention relates to a motor, in particular to a secure spark-proof motor. The secure spark-proof motor comprises a motor, a mounting carrier, a matching carrier, a carbon brush mounting shell, aloading / unloading device, a damping component, a protection shell, an auxiliary spinner and a cleaner; a hollow space can be formed through an inner shell and the protection shell; by utilizing the damping component, the vibration and noise generated during the operation of the motor are decreased; through changing the displacement amount of a boosting piece, the pressure applied to a carbon brushby a leaf spring can be increased or decreased, so that favorable contact between the carbon brush and a reversing ring is ensured and the generation of sparks is avoided; and through changing the lifting of a sponge mop and injecting cleaning liquid in a liquid inlet, the sundries such as oil stains or dust on the reversing ring can be cleaned.

Description

technical field [0001] The invention relates to a motor, in particular to a safe anti-spark motor. Background technique [0002] When using the motor carbon brush, due to the rotation of the rotor, the carbon brush always rubs against the commutation ring, so the carbon brush is a vulnerable part. Due to the continuous wear of the carbon brush during long-term operation, the pressure of the carbon brush is not enough or the collector ring is not round, and oil droplets or other debris on the bearing fall between the commutation ring and the carbon brush. And so on a variety of situations, will cause the carbon brush to emit sparks. If the spark phenomenon is not dealt with in time, the spark will become bigger and bigger, and then burn the carbon brush and commutator, cause the excitation circuit to be interrupted, and the brush holder will be burned. Contents of the invention [0003] The purpose of the present invention is to provide a safe anti-spark motor, which can ...
