Description

Technical Field

[0001] The utility model relates to the technical field of commutators, in particular to a combined commutator with convenient installation. Background Technique

[0002] A commutator, also known as a "commutator". It is an important component on the armature of a DC motor and an AC commutator motor. It consists of many copper sheets separated by mica sheets, forming a cylindrical or disc shape. Each copper sheet is connected to several armature winding elements. When the armature rotates, the copper sheets successively come into contact with the fixed carbon brushes. In a DC motor, the alternating current in the armature winding is converted into direct current between the carbon brushes through the carbon brushes and the commutator. In an AC commutator motor, the frequency of the alternating current between the carbon brushes meets the working requirements. The commutator is a key component, mainly used in motors and generators. Its core function is to keep the direction of the output current unchanged. When the motor rotates, each winding coil passes through the same fixed magnetic field twice per revolution, which causes the direction of the induced current in the winding to change. The role of the commutator is to keep the direction of the output current unchanged. The basic principle of the rectifier is to utilize the unidirectional conductivity of semiconductor materials to convert alternating current into a unidirectional direct current signal. In a rectifier, the diode is a key component. A diode is an electronic device with unidirectional conductivity. Its working principle is that in the forward bias case, electrons can pass through the conductor smoothly, and in the reverse bias case, a high resistance or insulating state will occur.

[0003] The application number is CN201910283064.X, which discloses a combined commutator, including a commutator body, a steel sleeve, a transfer piece fixing component, a commutator segment socket fixing component, a thread, a locking nut, a reinforcing ring, a guiding edge, a ring groove, a first insulating matrix, a first installation groove, a transfer piece, a connecting hook, a slot, a second insulating matrix, a second installation groove, a commutator segment, and a plug connector. A steel sleeve is arranged at the center inside the commutator body. One end of the steel sleeve is fixedly provided with a transfer piece fixing component, and ring grooves are formed on the outer walls of both sides at one end of the steel sleeve; in this invention, the structure is relatively simple and reasonable. Through the setting of the combined assembly structure of the transfer piece fixing component and the commutator segment socket fixing component, when the commutator segment wears and needs to be repaired and replaced, only the commutator segment socket fixing component needs to be disassembled and replaced, which solves the problem of high maintenance cost of the traditional commutator with an integral structure, and the maintenance and replacement process is relatively simple and convenient, which is beneficial for the operator to operate.

[0004] Although the above-mentioned utility model is provided with a combined assembly structure of a transfer piece fixing component and a commutator piece socket fixing component, when the commutator piece wears out and needs to be repaired and replaced, only the commutator piece socket fixing component needs to be disassembled and replaced, which solves the problem of high maintenance cost of the traditional commutator with an integral structure, and the maintenance and replacement process is relatively simple and convenient, which is conducive to the operation of workers. However, the disadvantage is that when the device is installed, the installation connection relationship is relatively cumbersome and the disassembly is inconvenient, which is likely to cause certain damage during subsequent disassembly and installation.

[0005] Therefore, it is necessary to install a reinforcing ring component in the device, so that when connecting the magnetic pole component and the rotor component, through this additional component, the connection can be made more convenient, and the connection boundary can be made more fixed, and the disassembly and installation are convenient.
