Description

Technical Field

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

[0002] A slip ring is an electrical component responsible for connecting and transmitting energy and signals to a rotating body. Based on the transmission medium, slip rings are classified into electrical slip rings, fluid slip rings, and smooth slip rings, and can also be commonly referred to as "rotational connectors" or "rotational connections." Slip rings are typically installed at the center of rotation of equipment and mainly consist of two parts: a rotating part and a stationary part.

[0003] The core of a conductive slip ring is the rotating sliding electrical contact between the brush and the ring track. Wear during use can generate particles that contaminate the internal environment, potentially causing short circuits or accelerating wear. Therefore, we propose a conductive slip ring to address these issues. Utility Model Content

The wear-resistant ring 12, the sealing ring assembly 11 and the inner oil seal 3 are snapped together in sequence. The inner oil seal 3, carrying the sealing ring assembly 11 and the wear-resistant ring 12, is snapped into the top of the inside of the fixed shaft 5. The rotating shaft 2 passes through the inside of the inner oil seal 3 and is inserted into the top of the inside of the fixed shaft 5.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, by setting an optimized and stable structure, during use, after the sealing ring assembly 11 is snapped onto the top of the inner oil seal 3, the wear-resistant ring 12 is snapped onto the sealing ring assembly 11 inside the top of the inner oil seal 3 and then contacts the top of the inner oil seal 3. The inner oil seal 3, carrying the sealing ring assembly 11 and the wear-resistant ring 12, is then snapped into the inside of the fixed shaft 5. After the rotating shaft 2 is inserted into the inside of the slip ring housing 1, it passes through the inside of the inner oil seal 3 at the top of the fixed shaft 5 and snaps into the rotating shaft 2. Through the sealing ring assembly 11 and the wear-resistant ring 12 at the top of the inner oil seal 3, the effect of light torque and high speed is achieved, thereby realizing the optimized and stable function.

[0023] The rotating shaft 2 is fitted with a double-row bearing 4. The bottom of the double-row bearing 4 is connected to a leather gasket 13. The top of the slip ring housing 1 is covered with an upper sealing pressure cover 7. The bottom of the upper sealing pressure cover 7 is snapped with a waterproof oil seal 9. The bottom of the waterproof oil seal 9 is snapped with a pressure plate 10. The bottom of the pressure plate 10 is fitted with an inner retaining ring 6. The inner retaining ring 6 is provided with a hole retaining ring 8 inside. The fixed shaft 5 is fitted with a nut 14.

[0024] The inner retaining ring 6 is fitted on the outside of the rotating shaft 2 and contacts the double-row bearing 4 fitted on the outside of the rotating shaft 2.
