Problems solved by technology

The collector ring of this structure has the following defects: first, the structure is complex, the carbon brush needs to be installed in the carbon brush sleeve, and the spring top pressure is required; second, the wear is fast, and the carbon brush needs to be replaced frequently; third, there are hidden dangers, carbon Toner powder generated by brush wear can easily cause short circuits
[0003] In order to overcome the defects of the above-mentioned prior art, the Chinese invention application (application number 201310315647.9) discloses an "underwater elastic wire collector ring", which is fixed with an elastic metal wire on the insulating block. One end of the wire is pressed against the outer circular surface of the metal ring, and the other end is connected to the wire on the stator. Although this structure is simpler and wear-resistant than traditional carbon brushes, the insulating card arranged on the stator 9 Once the block 3 is formed, its axial length cannot be lengthened, and the number of metal wires 4 installed on it is limited, so it is impossible to expand the number of input and output wires (including power lines and control lines) of the slip ring

Embodiment Construction

[0028] In order to make the technical solution of the present invention clearer, the following in conjunction with the attached Figures 1 to 10 , the present invention will be described in detail. It should be understood that the specific implementations described in this specification are only for explaining the present invention, and are not intended to limit the protection scope of the present invention.

[0029] The present invention is an expandable slip ring, which includes a stator 1 and a rotating shaft 2 of the slip ring. The stator 1 includes a casing 101 and upper and lower covers 102 and 103. A lower bearing 301 is arranged between the covers 103, and an upper rotating cover 4 is fixed on the upper end of the rotating shaft 2, and an upper bearing 302 is arranged between the upper rotating cover 4 and the upper cover 102, and in the cavity of the stator 1 There are a plurality of electric slip rings 5 ​​sleeved on the rotating shaft 2, and the plurality of electr...

Abstract

The invention discloses an extensible collector ring which comprises a stator and a rotating shaft of the collector ring, wherein the stator comprises a housing and upper and lower covers, a lower bearing is arranged between the lower end portion of the rotating shaft and the lower cover, an upper rotary cover is fixed on the upper end portion of the rotating shaft, an upper bearing is arranged between the upper rotary cover and the upper cover, a plurality of electric slip rings sleeving the rotating shaft are arranged in the cavity of the stator, and a plurality of electric slip rings are superposed along the axial direction and fixed on the lower end of the lower rotary cover through bolts. A plurality of elastic electric brushes are correspondingly arranged outside the plurality of electric slip rings, corresponding electric slip rings and the elastic electric brushes are electrically connected through electric metal wires on the elastic electric brushes, and the elastic electric brushes are extensibly arranged between the upper and lower covers through brush extensible devices. The extensible collector ring is simply structured and wear resistant, and the input and output lead quantity of the collector ring can be increased conveniently and flexibly to satisfy different requirements.

Description

technical field [0001] The invention relates to a slip ring, in particular to an expandable slip ring. Background technique [0002] Traditional collector rings are mainly composed of copper rings and carbon brushes pressed against the outer surface of the copper rings. The collector ring of this structure has the following defects: first, the structure is complex, the carbon brush needs to be installed in the carbon brush sleeve, and the spring top pressure is required; second, the wear is fast, and the carbon brush needs to be replaced frequently; third, there are hidden dangers, carbon Toner dust from brush wear can easily cause short circuits. [0003] In order to overcome the defects of the above-mentioned prior art, the Chinese invention application (application number 201310315647.9) discloses an "Underwater Elastic Wire Collector Ring", which is fixed with an elastic metal wire on the insulating block. One end of the wire is pressed against the outer circular surfa...
