Description

Technical Field

[0001] This utility model relates to the field of conductive slip rings, and more specifically, to a multi-loop conductive slip ring. Background Technology

[0002] Conductive slip rings, also commonly known as collector rings, slip rings, current collectors, or busbars, are used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. Slip rings improve system performance, simplify system structure, and prevent wires from twisting during rotation.

[0003] Currently, traditional conductive slip rings on the market have too many loops, which increases the length of the conductive slip ring. This can lead to poor coaxiality or deformation of internal connecting parts during operation, making the conductive slip ring prone to damage and affecting its performance. Utility Model Content

[0004] The purpose of this invention is to provide a multi-loop conductive slip ring to solve the technical problems existing in the background art.

[0005] This utility model provides a multi-loop conductive slip ring, including an outer shell, flange end caps and bearing end caps located at both ends of the outer shell, a ring assembly located inside the outer shell and movably connected at both ends to the flange end caps and the bearing end caps, a brush assembly located outside the ring assembly, and a reinforcing connection assembly located inside the outer shell.

[0006] The reinforcing connection assembly includes a reinforcing seat sleeved outside the ring assembly, a first support column connecting the reinforcing seat to the flange end cover, and a second support column connecting the reinforcing seat to the bearing end cover. The bearing end cover, flange end cover, ring assembly, and reinforcing seat are coaxially arranged.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figure 1-4 As shown, the present invention provides a multi-loop conductive slip ring, including a housing 1, flange end caps 2 and bearing end caps 3 located at both ends of the housing 1, a ring assembly 4 located inside the housing 1 and movably connected at both ends to the flange end caps 2 and the bearing end caps 3 respectively, a brush assembly 5 located outside the ring assembly 4, and a reinforcing connection assembly located inside the housing 1.

[0022] The brush assembly 5 contacts the ring assembly 4 to achieve current and signal transmission between them. Connecting bearings 6 are provided between the ring assembly 4 and both the bearing end cover 3 and the flange end cover 2, allowing the ring assembly 4 to rotate during operation. For multi-loop conductive slip rings, the large number of brush assemblies 5 results in a relatively long conductive slip ring. Under these conditions, this solution addresses the problem of insufficient coaxiality due to excessive length or deformation of internal connecting parts caused by torsion, which can easily damage the conductive slip ring. This also ensures stable power signal transmission from the bus ring, facilitates installation, and results in a compact structure.

[0023] The reinforcing connection assembly includes a reinforcing seat 7 sleeved on the ring assembly 4, a first support column 8 connecting the reinforcing seat 7 to the flange end cover 2, and a second support column 9 connecting the reinforcing seat 7 to the bearing end cover 3. The bearing end cover 3, flange end cover 2, ring assembly 4, and reinforcing seat 7 are coaxially arranged. The reinforcing seat 7 is located outside the ring assembly 4 and is fixed to the outer shell 1 by bolts. The reinforcing seat 7 is connected to the flange end cover 2 and the bearing end cover 3 by the first support column 8 and the second support column 9, respectively. The reinforcing seat 7, the first support column 8, and the second support column 9 serve as the mounting frame to ensure the connection stability between the brush assembly 5 and the ring assembly 4.

[0024] To further ensure the stability of the reinforcing components, four support columns 8 and 9 are provided, distributed on both sides of the reinforcing base 7. Each support column 8 and 9 has screw holes at both ends, and is connected to adjacent components via bolts.

[0025] Limiting holes are provided on the reinforcing seat 7, bearing end cover, and flange end cover. One end of the support column 8 is inserted into the limiting hole 10 on the flange end cover 2, and the other end is inserted into the upper limit hole 10 on the reinforcing seat, and the limiting hole 10 corresponds to the upper limit hole 10 on the flange end cover 2. One end of the support column 9 is inserted into the limiting hole 10 on the bearing end cover 3, and the other end is inserted into the upper limit hole 10 on the reinforcing seat 7, and the limiting hole 10 corresponds to the upper limit hole 10 on the bearing end cover 3.

[0026] During installation, the two ends of support column 1 8 are inserted into the limiting holes on flange end cover 2 and reinforcing seat 7, respectively, and then the two ends are fixed with bolts. The fixing method of support column 2 9 is similar to that of support column 1 8.

[0027] The brush assemblies 5 are arranged in several groups and located on both sides of the reinforcing seat 7. The brush assemblies on both sides are detachably installed between the reinforcing seat 7 and the flange end cover 2, and between the reinforcing seat 7 and the bearing end cover 3, respectively. The brush assembly has a through hole, and a locking rod 11 is installed through the through hole. The end of the locking rod 11 has a threaded structure, and the reinforcing seat 7 has a corresponding screw hole.

[0028] In this embodiment, four sets of brush assemblies 5 are provided, with two sets on each side of the reinforcing seat 7. During installation, the locking rod passes through the through hole and is inserted into the screw hole, then locked. The brush assemblies 5 on both sides are installed using the above-described installation method between the reinforcing seat 7 and the flange end cover 2, and between the reinforcing seat 7 and the bearing end cover 3, respectively. The reinforcing seat 7 separates and fixes adjacent brush assemblies 5, ensuring an effective and stable connection between the brush assembly 5 and the ring body assembly 4 even when the conductive slip ring is long. Of course, if the conductive slip ring has more loops, additional reinforcing seats 7 and support columns can be added to achieve stable installation and positioning of the brush assembly 5.

[0029] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
