Description

Technical Field

[0001] This utility model relates to the field of carbon commutators, specifically a carbon commutator. Background Technology

[0002] A commutator, also known as a rectifier, is an important component of the armature of both DC and AC commutator motors. It consists of numerous copper plates separated by mica sheets, arranged in a cylindrical or disc shape. Each copper plate is connected to several armature winding elements. As the armature rotates, the copper plates successively contact fixed brushes. In a DC motor, the brushes and commutator convert the alternating current (AC) in the armature windings into direct current (DC) between the brushes. In an AC commutator motor, it ensures that the frequency of the AC current between the brushes meets the operating requirements.

[0003] The existing carbon commutator and rotor are in a loose state, which can easily cause them to loosen and fall off during operation. Over time, the copper sheets on the commutator will affect the performance of the commutator itself, easily leading to poor commutation contact and low strength. Disassembly is required when lubricating the inside of the commutator. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a carbon commutator that solves the problems mentioned in the background section. In existing carbon commutators, the connection between the commutator and the rotor is loose, making it easy for the commutator to loosen and detach during operation. Furthermore, over time, the copper plates on the commutator can affect its performance, leading to poor commutation contact, low strength, and requiring internal disassembly for lubrication.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a carbon commutator, comprising a main body, a fixed end cap fixedly installed on the inner wall of one end of the main body, a connecting part installed on the inner wall of the fixed end cap, a connecting rod through the inner wall of the main body, and a reinforcing mechanism through the inner wall of the main body.

[0008] Furthermore, the outer wall of the fixed end cap is provided with assembly holes.

[0009] Furthermore, the reinforcing mechanism includes reinforcing ribs, with connecting platforms fixedly installed at the upper ends of the reinforcing ribs. Multiple sets of buffer grooves are formed between the connecting platforms. The inner wall of the connecting platform is filled with a buffer mechanism. A reinforcing block is fixedly installed on the outer wall of the buffer mechanism. A through hole is formed on the outer wall of the connecting platform.

[0010] Furthermore, the reinforcing rib is installed on the inner wall of the main body via a connecting platform, and the reinforcing rib is made of carbon fiber components.

[0011] Furthermore, the buffer groove is formed between the outer walls of the connecting platform, and the inner walls of the buffer groove are filled with rubber components.

[0012] Furthermore, the buffer mechanism includes a buffer pad, the inner wall of which is fixedly fitted with a lubricating layer, and the outer wall of which is provided with an oil injection hole.

[0013] Furthermore, the buffer pads are fixedly installed on the outer wall of the reinforcing ribs, and the buffer pads are fixedly installed on the inner wall of the main body through the reinforcing ribs. There are four sets of buffer pads, and the buffer pads are semi-circular in shape.

[0014] (III) Beneficial Effects
