5 New designs canalso be created to meet the most engineers are experienced in a widerange of slip ring applications. A very activein-house quality program solicits the bestinputs from all of our many concurrentengineering groups, from start to section is designed to guide you throughthe process of specifying a slip ring . We'veoutlined below the major considerations thata slip ring engineer will need to know aboutyour slip ring DesignThroughout these pages, you will see theterms " slip ring capsule" and " slip ringseparates". The term "separate" indicatesan individual rotor/brush block term "capsule" is used to denote a self-contained unit consisting of a rotor, stator andits own integral ball are two basic slip ring configurationsto consider based on space allocation inyour more common drum approach whereeach ring is adjacent to the next along thecenterline, somewhat like the threads on abolt, and2.
6 The pancake approach where the ringsare concentric with one another like thegrooves on a phonograph record. Thepancake approach is used when length isat a premium but diameter is the Mechanical EnvelopeThe envelope is, of course, largely dictatedby the space available in the system. Theslip ring engineer should be given themaximum space available in the system soall existing candidate designs can beconsidered. It is imperative that the spacerequired for the slip ring be specified in theearly stages of the system design and that itbe consistent with the structural and System InterfaceRequirementsThe slip ring engineer will need to know thesesystem interface considerations:1. Is a bore required through the slip ring forrouting coolant plumbing, hydraulic lines,pneumatic lines, waveguides, etc?
7 In suchapplications, the slip ring actually mountsconcentric with these lines in the How will the slip ring attach to the system?It is never advisable to hard mount both therotor and the stator to the system since theslip ring bearings may overload if there is anymisalignment between them and the How should the electrical connections tothe slip ring be made? Is it desirable to haveconnectors integral with the slip ring on boththe rotor and stator, or would flying leads onone or the other ends be desirable? And ifflying leads are preferred, should they exitthe rotor/stator in a radial or axial direction,and what length should the leads be?Defining Electrical RequirementsThe specified current enables the slip ringengineer to propose a unit with theappropriate cross-sectional area of the rings,brushes and lead wires.
8 The specified voltagedictates the spacing between adjacent ringsand brushes. It is helpful in achieving themost cost effective and smallest practicalenvelope not to rate all circuits at themaximum level. For example, if you need 20circuits total, three of which must carry tenamps, designate three for high current. Don'tinsist on 100% functional interchangeabilityby specifying that all 20 circuits carry tenamps. And, if ten amps is a surge currentwith a continuous current of only two amps,tell us that, too. There is no reason for you topay for ten amps continuous capacity whenyou only need aware that voltage surges and spikes arethe major cause of system slip ring Components Group uses aconservative approach to circuit design,however, it is not uncommon in some powersupply systems to see voltage spikes ten ormore times the normal operating voltage.
9 Westrongly recommend surge protection on allpower smaller slip rings will satisfactorilyconduct signals to 50 megabits/sec. Specialslip rings can be used to pass broadbandsignals from dc to 1 gigahertz and data ratesof 500 megabits or even higher. Cross-talk,insertion loss and bit error rate informationcan be provided if data rates, formats andimpedances are defined. The appropriateshielding techniques will be incorporated tomeet the system Mechanical Requirements1. Operating speed (rpm's) is an importantdesign parameter. Almost any slip ring canoperate successfully at speeds to 100 rpmalthough many applications only requireoperation at a few rpm. slip rings areroutinely used to instrument test jet turbineengines operating at speeds in excess of20,000 rpm. The operating speed, inconjunction with the diameter, dictates thesurface speed of the ring relative to thebrush and hence the internal designapproach and material What rotational life is necessary for yourapplication?
10 Will the unit oscillate or rotateat a continuous speed?Defining the EnvironmentThe environment in which the slip ring mustsurvive is a key factor. Operating temperaturerange is important in specifying the properlubricant. And if the slip ring will operateexposed to the elements or to a hostileenvironment, integral seals must be includedin the design. Any unusual shock or vibrationshould also be slip ring RequirementsFor assistance on your slip ring requirements,please complete the slip ring ApplicationSpecification Sheet located on page 7, youcan either fax or call and speak with one ofour engineers about your best slip of the slip ring designs and manufacturing processesdescribed are proprietary and are covered under one ormore , European or Japanese patents.
