Description

[0002] Conductive slip ring is a kind of rotating power transmission connector.

DETAILED DESCRIPTION

[0035] The technical solution provided by the present invention is further described below in conjunction with the accompanying drawings and according to specific implementation methods.

[0036] like Figure 1 to Figure 15 As shown, a column-type conductive slip ring with high reliability against redundant objects comprises a central axis 1, a combined bracket 2 is rotatably mounted on the outer ring at the bottom of the central axis 1, a 1-mm maze-like structure is formed between the bottom of the central axis 1 and the bottom of the combined bracket 2, a locking nut 5 is fixedly mounted on the middle outer ring of the central axis 1, a baffle is arranged on the outer ring of the locking nut 5, a bearing baffle 6 is fixedly mounted on the front end of the combined bracket 2 by bolts, a baffle is arranged on the inner ring of the bearing baffle 6, the baffle on the outer ring of the locking nut 5 cooperates with the baffle on the inner ring of the bearing baffle 6 to form a maze-like structure, and the maze-like structures at both ends can effectively prevent foreign objects from entering the interior of the combined bracket 2 when the slip ring is working, and at the same time do not affect the friction torque of the slip ring.

[0037] like Figure 1 to Figure 15As shown, a bearing steel sleeve 3 is fixedly installed on the inner ring of the combined bracket 2, and the top of the bearing steel sleeve 3 is fixedly installed on the combined bracket 2 by bolts. A pair of angular contact ball bearings 4 are fixedly installed between the inside of the bearing steel sleeve 3 and the outer ring of the central shaft 1. Supporting the central shaft 1 by multiple angular contact ball bearings 4 can effectively improve the load-bearing capacity of the slip ring during operation and reduce the risk of the slip ring getting stuck due to peripheral measurement or excessive temperature during operation.

[0038] like Figure 1 to Figure 15 As shown, a push wheel support ring 14 is fixedly installed at the bottom of the locking nut 5, and a plurality of push wheel brackets 13 are fixedly installed on the inner ring of the push wheel support ring 14. A push wheel 12 is rotatably installed in the push wheel bracket 13. A plurality of foreign object push blocks 10 are radially slidably installed on the inner ring of the bearing baffle 6. The foreign object push blocks 10 are used to prevent larger foreign objects from being stuck in the gap between the bearing baffle 6 and the locking nut 5. A compression spring is fixedly installed between the foreign object push block 10 and the bearing baffle 6. Side push blocks 11 are laterally slidably installed on both sides of the foreign object push block 10, and a compression spring is fixedly installed between the side push block 11 and the foreign object push block 10. The push wheel 12 rolls with the rear end of the foreign object push block 10, and the number of the push wheels 12 is half of the foreign object push block 10. When the slip ring is started, the rotation of the central shaft 1 drives the locking nut 5 to rotate synchronously, and the contact and cooperation between the push wheel 12 and the foreign object push block 10 pushes the foreign object push block 10 to slide toward the center in the bearing baffle 6, pushing out large foreign objects that may be stuck between the locking nut 5 and the bearing baffle 6, preventing foreign objects from getting stuck in the gap and scratching parts. At the same time, in combination with the maze-like structure, it can effectively prevent foreign objects from entering the interior of the combined bracket 2 and affecting the normal operation of the angular contact ball bearing 4.

[0039] like Figure 1 to Figure 15 As shown, a plurality of collecting grooves 9 are evenly arranged on the outer ring at the rear end, and the collecting grooves 9 are connected to the end of the central shaft 1. A waste oil collecting rod 8 is fixedly installed in the collecting groove 9. The interior of the waste oil collecting rod 8 is toothed. The waste oil collecting rod 8 is used to collect the mixture of waste oil and dust generated by the angular contact ball bearing 4 during operation. The toothed structure on the waste oil collecting rod 8 can better buffer the waste oil, so that the angular contact ball bearing 4 can maintain a good working condition.

[0040] like Figure 1 to Figure 15As shown, a transmission shaft 18 is fixedly installed at the rear end of the central shaft 1, and a plurality of adjustment slots 30 are arranged on the transmission shaft 18. A sliding support ring 22 is installed on the transmission shaft 18 for transverse sliding movement. An adjustment support ring 19 is rotatably installed at the front end of the sliding support ring 22. A positioning slider 35 is fixedly installed on the inner ring of the adjustment support ring 19. The positioning slider 35 is slidably matched with the adjustment slot 30. A key is slidably installed in the positioning slider 35 through a compression spring. The front end of the adjustment slot 30 is an inverted L-shape and is provided with a slot. The key in the positioning slider 35 is matched with the slot at the front end of the adjustment slot 30 for adjusting the adjustment support. The sliding position of the ring 19 and the sliding support ring 22 on the transmission shaft 18 is convenient for taking out the waste oil collection rod 8 when checking and cleaning the slip ring. A reset push plate 31 is slidably installed at the rear end of the transmission shaft 18, and a reset rod is fixedly installed at the front end of the reset push plate 31. The reset rod at the front end of the reset push plate 31 is slidably installed in the adjustment slide groove 30, and the front end of the reset rod is in contact with the positioning slider 35. By pressing the reset push plate 31, the key in the positioning slider 35 is retracted, so that the adjustment support ring 19 can rotate on the transmission shaft 18, and its sliding position on the transmission shaft 18 can be adjusted.

[0041] like Figure 1 to Figure 15 As shown, the rear end of the combined bracket 2 is fixedly installed with a first support shell 15 and a second support shell 16. The first support shell 15 and the second support shell 16 are hinged, so that when the slip ring is inspected and cleaned, the adjustment support ring 19 and the sliding support ring 22 can be adjusted, and the inspection and cleaning are more convenient. The first support shell 15 and the second support shell 16 are both provided with a sealing semicircular rod 33 and a sealing semicircular groove 34. The sealing semicircular rod 33 and the sealing semicircular groove 34 on the first support shell 15 and the second support shell 16 cooperate with each other to form a maze-like structure, which is used to prevent external foreign matter from entering and increase the stability when cooperating with each other. The rear end of the first support shell 15 and the second support shell 16 is fixedly installed with a sealing bottom plate 24, and the rear end of the sealing bottom plate 24 is fixedly installed with a plurality of bottom wiring heads 27. A rotating groove is provided in the sealing bottom plate 24. A sealing plate 25 is fixedly installed at the rear end of the transmission shaft 18. The sealing plate 25 rotates with the rotating groove in the sealing bottom plate 24 and is combined into a maze-like structure. A transmission gear 26 is fixedly installed at the rear end of the sealing plate 25 for connecting with an external drive device.

[0042] like Figure 1 to Figure 15As shown, a plurality of positioning rings are fixedly installed on the inner walls of the first supporting shell 15 and the second supporting shell 16, a brush supporting ring 28 is fixedly installed on the positioning ring of the inner ring of the first supporting shell 15 and the second supporting shell 16, a plurality of slip ring brushes 29 are fixedly installed on the inner ring of the brush supporting ring 28, and the slip ring brushes 29 are correspondingly connected to the bottom terminal 27 through a wire, and an inner concave conductive ring 21 is fixedly installed on the adjusting support ring 19 and the sliding support ring 22, and the slip ring brushes 29 are in contact with the inner concave conductive ring 21, and a plurality of side terminal heads 17 are fixedly installed on the outer rings of the first supporting shell 15 and the second supporting shell 16. The head 17 is connected through the slip ring brush 29 corresponding to the wire, and multiple pairs of wear material temporary storage rings 20 are fixedly installed on the inner rings of the adjusting support ring 19 and the sliding support ring 22. The wear material temporary storage rings 20 are fixedly installed on the left and right sides of the concave conductive ring 21. A cache groove for storing wear materials is provided in the wear material temporary storage ring 20, and the entrance of the cache groove is located on one side of the concave conductive ring 21. The wear material temporary storage ring 20 is used to cache the wear materials generated by the friction between the slip ring brush 29 and the concave conductive ring 21 when the slip ring is working, so as to prevent the wear material from causing poor contact between the wear material temporary storage ring 20 and the slip ring brush 29 due to the influence of the wear materials, resulting in the failure of the slip ring to work normally.

[0043] like Figure 1 to Figure 15 As shown, a plurality of guide grooves 32 are provided at the bottom of the positioning rings on the inner walls of the first supporting shell 15 and the second supporting shell 16, and the guide grooves 32 pass through all the positioning rings. A waste oil collecting ring 23 is fixedly installed at the bottom between the first supporting shell 15 and the second supporting shell 16, and a plurality of attachment plates are provided inside the waste oil collecting ring 23. The waste oil collecting ring 23 is used to buffer the waste oil generated when the slip ring is working.

[0044] Working principle: When the slip ring is enabled, the transmission shaft 18 and the center shaft 1 are driven to rotate through the cooperation of the external motor and the transmission gear 26. When the center shaft 1 rotates, the locking nut 5 is driven to rotate synchronously. When the locking nut 5 rotates, the push wheel 12 is driven to revolve. Through the contact and cooperation between the foreign object push block 10 and the push wheel 12, the foreign object push block 10 slides alternately in the bearing baffle 6, and foreign objects that may be stuck between the locking nut 5 and the bearing baffle 6 are pushed away. During operation, the maze-like structure at both ends of the angular contact ball bearing 4 can effectively prevent smaller foreign objects from entering the interior of the combined bracket 2.

[0045] During the operation of the slip ring, the waste oil generated by the angular contact ball bearing 4 during operation is collected and cached through the waste oil collection rod 8, and the waste oil inside the first support shell 15 and the second support shell 16 is diverted to the guide groove 32 for cache through the guide groove 32 to prevent the working state of the slip ring from being affected by the waste oil during operation. At the same time, the wear material temporary storage ring 20 is used to cache the wear materials generated during the operation of the slip ring to prevent poor contact during operation of the slip ring.

[0046] When inspecting and cleaning the slip ring, the first support shell 15 and the second support shell 16 hinged to each other are opened to clean the inside, then the reset push plate 31 is pressed and the adjustment support ring 19 is rotated, and then the adjustment support ring 19 and the wear material temporary storage ring 20 are pushed to slide toward the rear end of the transmission shaft 18, and the distance between the adjustment support ring 19 and the waste oil collection rod 8 is increased, so that the waste oil collection rod 8 can be taken out for cleaning.
