Description

Technical Field

[0001] This utility model relates to the field of conductive rings, and in particular to a riveted conductive ring. Background Technology

[0002] A conductive ring is an electromechanical device that can stably transmit power, signals, or data between fixed components through continuous rotation. Its applications are wide-ranging, covering many important industries such as machinery, aerospace, medical equipment, energy, and automated production. Existing conductive rings are usually made by stamping the conductive ring and then inserting carbon fiber from the top. On the one hand, the stamping process requires polishing, which affects the production cost and efficiency of the product. On the other hand, the way the carbon fiber is inserted can easily lead to blockage, which can obstruct the current transmission path of the product, significantly reduce the conductivity, and thus affect the overall performance. Furthermore, the utilization rate and service life of the carbon fiber are also insufficient. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a riveted conductive ring that is easy to install, does not clog the carbon fiber, and allows for higher utilization of the carbon fiber.

[0004] To achieve the above objectives, this utility model provides a riveted conductive ring, comprising a housing and several carbon brushes. The housing is arranged in a ring shape and is formed by riveting together an upper housing and a lower housing. The lower housing includes several mounting grooves arranged circumferentially along the inner diameter of the housing, and elastic elements are provided in the mounting grooves. One end of each carbon brush extends into the inner hole of the housing, and the other end of the carbon brush extends into the mounting groove and abuts against the elastic element.

[0005] The advantages of the above technical solution are as follows: the structural design of riveting the upper and lower shells together greatly simplifies the installation process and improves assembly efficiency. Furthermore, the carbon brush is positioned by the circumferentially arranged mounting grooves on the inner diameter of the lower shell. One end of the brush abuts against the elastic element in the mounting groove, while the other end extends directly into the inner hole of the shell. This avoids the blockage problem that may occur when the carbon fiber is inserted from the top in the prior art, ensuring a smooth current transmission path and effectively guaranteeing conductivity. Finally, the elastic abutment allows the carbon fiber to be dynamically adjusted in the carbon brush, reducing material waste, increasing the utilization rate of carbon fiber, and thus extending the service life of the conductive ring.

[0006] The present invention can be further configured such that: the upper housing includes a plurality of circumferentially spaced protrusions, the plurality of protrusions are arranged corresponding to the mounting groove positions, and the protrusions can extend into the mounting groove and abut against the carbon brush.

[0007] With further design, the protrusions on the housing correspond precisely to the mounting grooves on the lower housing. When the housings are assembled, the protrusions extend into the mounting grooves and directly abut against the carbon brushes, which not only provides axial restraint for the carbon brushes but also allows them to engage with the elastic elements through their own friction, ensuring that the carbon brushes always maintain stable contact with the rotating shaft.

[0008] The present invention can be further configured such that: the lower housing includes a retaining edge formed by extending from its outer diameter, and the retaining edge can be sleeved on the outer diameter of the upper housing.

[0009] With further design, the lower housing is fitted onto the outer diameter of the upper housing via a flange formed by the extension of the outer diameter, thereby enhancing the integrity and connection strength of the two.

[0010] The present invention can be further configured such that: the lower housing includes an annular groove adjacent to the retaining edge, and the upper housing includes an annular edge, the annular edge being able to be inserted into the annular groove.

[0011] By further designing the lower and upper housings, annular grooves and annular edges are respectively provided, allowing the two to interlock through the grooves and edges. With the addition of a retaining edge, initial positioning can be achieved through the interlocking, and subsequent installation can be completed by installing rivets.

[0012] The present invention can be further configured such that: the housing is provided with a riveting hole and an oil hole, the riveting hole allows a rivet to be inserted to form a fixation between the upper housing and the lower housing, and the oil hole allows lubricating oil to flow to both sides of the housing, and the riveting hole and the oil hole are arranged in a ring-shaped circumferential arrangement on the housing.

[0013] By further designing the housing, rivet holes and oil holes are arranged in a ring around the perimeter, allowing lubricating oil to flow through the oil holes to both sides of the housing, reducing friction loss. In addition, the ring distribution method ensures that the housing is subjected to uniform stress, avoiding structural deformation caused by local stress concentration, providing a stable installation reference for the carbon brush, and indirectly ensuring the consistency of carbon fiber distribution.
