Embodiment
[0063]The power conductive ring of the present invention includes: five conductive ring pieces 1 , five terminal posts 2 , and at least five M4 self-locking screws 7 . The conductive ring 1 is provided with an M8 terminal hole 4, four R6 terminal slots 5, and a flat keyway. The terminal 2 is arranged in the M8 terminal hole 4 on the conductive ring 1 , and the five conductive rings 1 are connected through the terminal 2 . The M4 self-locking screw 7 is set at one end of the terminal 2 to fix the terminal 2, such as image 3 shown. Wherein, the smoothness of the conductive ring piece 1 is not less than 0.3.
[0064] The diameter of the hole 4 of the M8 binding post is 6.7mm, and it is manufactured by using an M8 tap. The terminal holes 4 and the four R6 terminal slots 5 are arranged symmetrically on the same pitch circle. The self-locking screw 7 engages with the terminal post 2, and can firmly fix the terminal post 2 so that it will not deviate during the rotation process....

The invention discloses a power conducting ring which comprises at least one conducting ring piece, at least one binding post and at least one self-locking screw, wherein each conducting ring piece is a silver-copper alloy part for being connected with and conveying energy and signals, each binding post is connected with the corresponding conducting ring piece, each self-locking screw is arranged at one end of the corresponding binding post and used for fixing the same, and the conducting ring pieces are connected through the binding posts. The invention further discloses a production method of the power conducting ring. By the method, the surface of the power conducting ring is machined by a cutter and lubricants by means of extrusion, so that surface smooth finish of the power conducting ring is improved. The power conducting ring is high in surface smooth finish, good in contact surface with an electric brush and excellent in conductivity. A self-locking screw fixing method solves the problem of looseness of the binding posts during high-speed rotation of the conducting ring, firmness of the binding posts and the conducting ring are greatly improved, and maintenance cost is lowered.
Description
technical field [0001] The invention relates to a conductive ring, in particular to a power conductive ring and a manufacturing method thereof. Background technique [0002] The silver-copper-vanadium alloy technology in the prior art is unstable. Vanadium has the characteristics of high melting point, easy oxidation, and insoluble silver and copper. It cannot be melted by direct addition. The produced alloy is no different from silver-copper alloy, and cannot reach silver-copper Vanadium alloy effect, silver-copper-vanadium alloy has higher strength, better oxidation resistance and wear resistance than silver-copper alloy. The inventor obtained the silver-copper-vanadium alloy through special methods of vacuum melting and vacuum casting. The destructive test and actual use show that the silver-copper-vanadium alloy has excellent performance. [0003] In the early stage of the existing technology, non-vacuum centrifugal casting was mostly used to form tube blanks or ring b...
