The invention discloses a conductive slip ring which comprises a rotor and a stator arranged at the periphery of the rotor and matching the rotor. The rotor comprises a spindle and conductive columns. The spindle is circumferentially sleeved with ring channels communicated with the conductive columns, and insulating parts which sleeve the spindle are arranged between adjacent ring channels. The insulating parts and the ring channels are provided with through holes for placing the conductive columns. Rotor insulating sleeves are arranged between the spindle and the ring channels and between the conductive columns and the ring channels respectively. According to the conductive slip ring disclosed by the invention, through arrangement of the insulating parts and the ring channels on the spindle and a superposed rotor structure, the accuracy of dynamic balance is increased, loading and unloading for dynamic balance is more convenient, the concentricity of the rotor is improved, and reliable contact between the carbon brush and the ring channels during high-speed rotation of the rotor is satisfied.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, and more specifically, to a conductive slip ring. Background technique [0002] Conductive slip ring is a precision power transmission device that uses the sliding contact, electrostatic coupling or electromagnetic coupling of the conductive ring to transmit electrical signals and electric energy between the rotating parts of the fixed frame and the rolling or sliding parts. It is required in the process of modern industrial development. The product is used for reliable electrical connection between two parts that rotate relatively. Conductive slip rings are also called collector rings, or rotary joints, rotary electrical interfaces, slip rings, current collector rings, return rings, and adapters. [0003] The slip ring is generally composed of a rotor and a stator. The rotor is generally a cast-in-place structure. The dynamic balance accuracy and the concentricity of the rotor cann...
