Description
Technical field
The utility model relates to electric appliances to be electrically connected technical field, more particularly to a kind of conducting ring and can extend using the longevity
The electric slip ring of life.
Background technique
In traditional electric slip ring, carbon brush structure, brushing needle structure, cellulose brush knot are generally with the conduction brush of conducting ring cooperation
Structure.
The characteristics of carbon brush structure electric slip ring are as follows: face and face contact, relative rotary motion, contact area is big, heat generate compared with
It is more, the working life of other components is influenced, is in addition worn too greatly, long-term friction will appear a large amount of insulating powders, need often
Carbon brush is replaced, maintenance period is short, and use cost increases, and service life is short.
The characteristics of brushing needle structure electric slip ring are as follows: point and point contact, but each circuit contact point is less (such as 2 or 4),
This structural wear is smaller than carbon brush structure electric slip ring, and long-term friction also will appear the black powder that largely insulate, few additionally, due to contact point,
After insulating powder occurs in contacting points position, communication error code will cause, cannot correctly transmit signal, this needs is regularly maintained (such as
Clean circuit and brushing needle), can just slip ring be made to work normally, to increase maintenance workload and use cost.
The characteristics of fibre bundle brush gear electric slip ring are as follows: point and point contact, it is low, wear-resisting and elastic by many resistivity
Good tiny fiber filament group bunchy brush.Beam, which brushes flat, is layered on conducting ring circuit surface (conductive ring surface is plane), makes every
Fiber filament is all in contact with circuit, so contact point is more.It statistically analyzes, contact point is more, and transmission signal is more reliable.It is fine
It is reliable to tie up beam brush gear slip ring transmission signal, due to being that tiny fiber filament forms, pressure when contacting with circuit is smaller, and
Stability is good, wears also small, long service life.But the service life is unreliable when transmitting high-power (high current), is suitable for signal and transmits.
The characteristics of face structure high-power slip ring, is: face and face contact, but sliding block and circuit are using wear-resisting and included lubrication
Material production.Face and face contact ensure that the reliability of high power transmission, big as power slip ring transimission power, wear-resisting and included
The material production of lubrication ensure that service life and the maintenance-free performance of product.
In conclusion different electric slip ring structures or form respectively to have the characteristics that different, electric cunning is advanced optimized
The structure of ring designs, so that it is with better performance, it is those skilled in the art's technical problem urgently to be resolved.
