Around the stability and reliability on the slip ring

Slip rings as a crucial element of automation equipment , its stability and reliability and stability in the entire equipment reliability have very sophisticated relationships , it can be said former determines the latter , so the top quality slip ring for sophisticated precision instruments and equipment is crucial. Here's stability and reliability of your slip ring to perform some study instructions.

Slip ring its principal technical indicators have insulation properties, resistance to interference, speak to resistance , and so on. In this paper, these three inquiries on the extensively used in celestial navigation , optical tracking, measuring and optical devices similar to optical search precision slip ring , were analyzed one by 1 .

Insulation

The slip ring is , naturally, the larger the much better insulation properties , no less than , the insulation resistance between the rings and not be higher than the breakdown voltage , otherwise it truly is simple to slip ring reliability trouble. Slip ring consists of a large number of rings, the smaller the distance involving the rings as possible. Could possibly be reality, but depends on the processing in the groove , far more importantly, may be the result of post-guarantee Glue dielectric strength involving the rings . Radial slip ring substantial size plastic irrigation easy, and compact size are problematic Glue , its dielectric strength also depends upon the insulating material filling glue formulations and processes .

Anti-jamming efficiency because the transmission of electrical signals and microwave signal collector rings , immunity to complete improved on the reliability of information transmission much more safe , in reality , slip ring transmission dozens of numerous signals, one can find higher voltage alternating current, high frequency alternating existing, direct current with modest signal weak , a large existing AC , because the distance between the slip ring close to a number of signal in the course of transmission interference with each other , there was the electrostatic induction coupling , magnetic induction coupling and electromagnetic induction coupling . Interference caused by electrostatic induction coupling , etc., all types of interference seriously impact the accuracy with the details transmission . For this reason , superior anti-jamming efficiency slip ring , you need to start off from greater than a few major factors .
Contact resistance

Why should get in touch with resistance as a very critical technical indicator? Considering, if the conductive slip ring sliding contact resistance is also substantial , the current through the get in touch with point when the temperature will rise a great deal, and might possibly even bring about wire brush and slip ring welding , while the contact pressure drop increases , which will influence the facts transmission effect . For that reason, the make contact with resistance is smaller sized the much better way.

So, the elements affecting the size of your speak to resistance are those that do ? Mainly within the following elements: 1 ) the make contact with part with the material
2 ) forms the get in touch with surface plus the speak to when the make contact with stress.
Specifications of the material may be the material very good thermal conductivity, higher melting point, high conductivity, temperature coefficient of resistance is tiny, with anti-curing , anti-oxidation , anti- corrosive gases as well as other qualities with the brush filaments requirements are reasonably higher , you can easily use gold nickel wire but gold nickel wire high-priced. Based on the solution different applications , you'll be able to use brass wire instead.

The above two points , regardless of whether it's for customers of the through bore slip rings , slip rings or the production on the manufacturer , really should be placed in a highly essential position , it may be stated is the most significant , the only way we Jing Pei Electronics slip ring merchandise shall be guaranteed , we've to guard the infrastructure components , we've many different automated machinery and gear protection .
