AI Technical Summary
The existing slip rings are quite heavy, making them inconvenient to install and disassemble.
The spindle and conductive ring are connected by fasteners through the engagement of the first and second protrusions, and a cavity is formed between the protrusions to reduce weight. At the same time, shims and washers are used to reduce friction.
This allows for easy disassembly of the slip ring and reduces the overall weight.

Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of power transmission and distribution, and particularly relates to a current collecting ring. BACKGROUND
[0002] A current collecting ring, also known as a slip ring or a conductive ring, is a device used to transmit power or signals, widely used in rotating equipment such as motors, generators, radar antennas, etc. Its main function is to transfer current or electrical signals between rotating and stationary parts, thereby avoiding cable entanglement or twisting.
[0003] The current collecting ring generally includes a main shaft and a conductive ring, wherein the conductive ring is fixedly connected to the outer side of the main shaft by fasteners, and then the main shaft is sleeved on the outer side of the motor rotor. In actual use, the existing current collecting ring has the problems of heavy overall weight and inconvenience for installation and disassembly. SUMMARY
[0004] In view of the problems of heavy overall weight and inconvenience for installation and disassembly of the existing current collecting ring, the following utility model is proposed:
[0005] A current collecting ring, comprising a main shaft and a conductive ring stacked on the upper and lower sides of the main shaft, characterized in that: the main shaft comprises a shaft sleeve, a plurality of first protrusions are arranged in a ring shape on the outer side of the shaft sleeve, first fixing holes are arranged on the first protrusions, the conductive ring comprises a ring sleeve, a plurality of second protrusions are arranged in a ring shape on the inner side of the ring sleeve, second fixing holes are arranged on the second protrusions, and fasteners are inserted into the second fixing holes and the first fixing holes to fixedly connect the main shaft and the conductive ring.
[0006] Further, the first protrusions and the second protrusions are in a triangular shape, and cavities are formed between the protrusions to reduce the overall weight of the current collecting ring.
[0007] Further, a gasket is fixedly arranged between the conductive ring and the main shaft, and the gasket is penetrated by the fasteners. The gasket can prevent the conductive ring and the main shaft from directly rubbing against each other.
[0008] Further, a first gasket is arranged between the gasket and the conductive ring, and a second gasket is arranged between the fastener and the conductive ring.
[0009] The current collecting ring has the beneficial effects that the main shaft and the conductive ring are connected by the first protrusions and the second protrusions arranged thereon, which facilitates disassembly, and cavities are formed between the protrusions to reduce the overall weight of the current collecting ring.
