Description

Technical Field

[0001] This utility model relates to the field of slip ring technology, and more specifically, to a novel slip ring. Background Technology

[0002] Slip rings, also known as conductor rings, current collector rings, or collector rings, 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. Motors using slip rings, such as synchronous and asynchronous motors, are widely used in industrial sectors, often operating under harsh conditions. During operation, slip rings rotate at high speeds, demanding high stability. Poor stability can lead to violent movement of the slip ring and even the entire rotor system. This intense vibration can cause serious consequences, such as increased wear and tear on the brush-slip ring contact surface, resulting in poor contact, arcing, abnormal heating, noise, significantly shortened brush and ring lifespan, and even power outages or signal interruptions. Currently, there is a lack of effective, convenient, and independent dynamic balancing optimization and stability improvement solutions for slip ring components themselves. Especially in applications where slip rings require frequent maintenance or replacement, ensuring excellent stability and low vibration levels at high speeds has become a pressing technical challenge. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of slip ring with high stability and strong safety performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel current collector ring includes a cylindrical epoxy sleeve. An upper spacer ring is fitted at the end of the epoxy sleeve, a middle spacer ring is fitted in the middle, and a lower spacer ring is fitted at the bottom. A phase ring one is provided between the upper spacer ring and the middle spacer ring, and a phase ring two is provided between the middle spacer ring and the lower spacer ring. A groove with an opening facing the phase ring two is provided inside the middle spacer ring. A counterweight is provided inside the groove. The end of the counterweight extends out of the groove and is assembled onto the phase ring two. A conductive rod one and a conductive rod two are provided on the upper spacer ring. The conductive rod one extends from the upper spacer ring into the phase ring one and passes through the phase ring one, and its end abuts against the middle spacer ring. The conductive rod two extends from the upper spacer ring, passes through the phase ring one, the middle spacer ring, and the phase ring two, and its end abuts against the lower spacer ring.

[0005] The present invention is further configured such that: the upper end face and the lower end face of phase ring one and phase ring two are provided with concave annular cavities, wherein the upper spacer ring is located in the annular cavity of the upper end face of phase ring one, the upper end face of the middle spacer ring is located in the annular cavity of the lower end face of phase ring one, and its lower end face is located in the annular cavity of the upper end face of phase ring two, and the lower spacer ring is located in the annular cavity of the lower end face of phase ring two.

[0006] The present invention is further configured such that the upper spacer ring and phase ring one, and the lower spacer ring and phase ring two are all fixed by multiple bolts.

[0007] By adopting the above technical solution, a counterweight is placed inside the intermediate spacer ring, enabling precise dynamic balancing of the slip ring during high-speed rotation. This design effectively reduces vibration and noise caused by uneven mass distribution, significantly improving the operational stability and reliability of the slip ring and even the entire rotor system under high-speed conditions. The nested arrangement of the upper, middle, and lower spacer rings with the phase rings ensures precise axial positioning between components, resulting in a compact and stable overall structure. This modular design enhances mechanical strength and facilitates assembly. Attached Figure Description

[0013] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0014] A novel current collector ring includes a cylindrical epoxy sleeve 1. An upper spacer ring 2 is fitted at one end of the epoxy sleeve 1, a middle spacer ring 3 is fitted at the middle, and a lower spacer ring 4 is fitted at the bottom. A phase ring 5 is provided between the upper spacer ring 2 and the middle spacer ring 3, and a phase ring 6 is provided between the middle spacer ring 3 and the lower spacer ring 4. The middle spacer ring 3 has a groove 30 with its opening facing the phase ring 6. A counterweight block 31 is provided in the groove 30. The end of the counterweight block 31 extends out of the groove 30 and is assembled on the phase ring 6. The upper spacer ring 2 has a conductive rod 7 and a conductive rod 8. The conductive rod 7 extends from the upper spacer ring 2 into the phase ring 5 and passes through the phase ring 5, and its end abuts against the middle spacer ring 3. The conductive rod 8 extends from the upper spacer ring 2, passes through the phase ring 5, the middle spacer ring, and the phase ring 6, and its end abuts against the lower spacer ring 4.

[0015] Both the upper and lower ends of phase ring 5 and phase ring 6 are provided with concave annular cavities 50. The upper spacer ring 2 is located in the annular cavity 50 on the upper end of phase ring 5, the upper end of the middle spacer ring 3 is located in the annular cavity 50 on the lower end of phase ring 5, and its lower end is located in the annular cavity 50 on the upper end of phase ring 6. The lower spacer ring 4 is located in the annular cavity 50 on the lower end of phase ring 6. The upper spacer ring 2 is fixed to phase ring 5, and the lower spacer ring 4 is fixed to phase ring 6 by multiple bolts 9.

[0016] The addition of a groove 30 within the intermediate sleeve ring 3, along with the built-in counterweight 31, enables precise dynamic balancing of the slip ring during high-speed rotation. This design effectively reduces vibration and noise caused by uneven mass distribution, significantly improving the operational stability and reliability of the slip ring and the entire rotor system under high-speed conditions. Furthermore, the built-in structure of the counterweight 31 enhances assembly stability and robustness, preventing damage and external interference during operation.
