Abstract
The utility model discloses a rolling friction electric slip ring which consists of an outer raceway, an inner raceway and a rolling body. The rolling friction electric slip ring has the key points that the inner raceway is arranged in the middle of the outer raceway; the outside surfaces of the two ends of the inner raceway are provided with spherical grooves; the corresponding surfaces of the outside surfaces of the two ends of the outer raceway and the two ends of the inner raceway are respectively provided with spherical grooves corresponding with the outside surfaces of the two ends of the inner raceway; and the rolling body is arranged in a rail consisting of the corresponding two spherical grooves of the corresponding surfaces of the outer raceway and the inner raceway. The rolling friction electric slip ring has reasonable design and is convenient to manufacture; the rolling body can realize pure rolling in the rail between the inner raceway and the outer raceway to achieve the purposes of improving the performance of a rolling friction pair so as to satisfy the purposes of high reliability, long service life, and maintenance-free use of the rolling slip ring. The rolling friction electric slip ring solves the technical problem of invalidation of the slip ring caused by grinding powder generated due to rolling friction when the slip ring is in use in the prior art. The rolling friction electric slip ring can be widely applied to the technical fields of electronic signal transmission devices like radar, etc.
Description
Technical field the utility model belongs to electronic signal transmission device technology fields such as radar, relates to a kind of improvement of slip ring syndeton.Be specifically related to the electric slip ring of a kind of rolling friction.
The background technology slip ring is used very extensive at electronic technology field, and traditional slip ring adopts sliding friction to electrically contact secondary contact form, its Contact Pair is made up of brush and conducting ring, and brush is implemented in being electrically connected of rotating part and standing part in the conducting ring mantle friction.The slip ring of prior art, the sliding friction between the contact material must cause a large amount of grinding powder to produce, and in use cause the slip ring insulator resistivity decreased easily, thereby cause the inefficacy of slip ring.Slip ring in use requires to safeguard, thereby causes the increase of slip ring use cost.
The summary of the invention the purpose of this utility model is to solve the prior art slip ring in use owing to sliding friction produces the technical problem that the grinding powder causes slip ring to lose efficacy, and provides a kind of rolling friction electric slip ring, to overcome the deficiencies in the prior art.
To achieve these goals, the electric slip ring of the utility model rolling friction, it is made up of outer raceway, interior raceway and rolling element, its main points are centres that interior raceway is installed in outer raceway, the two ends lateral surface of interior raceway is provided with spherical groove, the corresponding surface of outer raceway two ends and interior raceway two ends lateral surface is respectively equipped with and the corresponding spherical groove of interior raceway two ends lateral surface, and described rolling element places in the track that is made of outer raceway and corresponding two spherical grooves of interior raceway corresponding surface.
The utility model reasonable in design, easy to make can realize pure rolling in the track of rolling element between inside and outside raceway, reach the performance that improves rolling friction pair, thereby has satisfied the purpose of rolling slip ring high reliability, non-maintaining use of long-life.The utility model has solved prior art and has existed slip ring in use owing to sliding friction produces the technical problem that the grinding powder causes slip ring to lose efficacy, and the utility model can be widely used in electronic signal transmission device technology fields such as radar, wind power generation, oil drilling, medical treatment.
Appended drawings is the utility model structural representation.
Embodiment with reference to the accompanying drawings, the utility model, it is made up of outer raceway 1, interior raceway 2 and rolling element 3, interior raceway 2 is installed in the centre of outer raceway 1, the two ends lateral surface of interior raceway 2 is provided with spherical groove, the corresponding surface of outer raceway 1 two ends and interior raceway 2 two ends lateral surfaces is respectively equipped with and the corresponding spherical groove of interior raceway 2 two ends lateral surfaces, and rolling element 3 places in the track that is made of outer raceway 1 and corresponding two spherical grooves of interior raceway 2 corresponding surfaces.
The utility model rolling slip ring structure has been improved the defective of traditional slip slip ring, and it uses one or more rolling elements and inner and outer ring raceway to replace sliding brush and slip ring circuit, replace sliding contact with the contact of rolling, thereby moment of friction reduces significantly.Simultaneously, because rolling element can produce elastic deformation, contact area is increased, contact pressure is stable, has improved the fluctuating nature of slip ring resistance greatly.
