How To Specify A Slip RingMany of the more than 10,000 slip ringdesigns are available for use in their existingconfiguration or they may be modified tomeet your specific requirements. Newdesigns can also be created to meet the mostdemanding specifications.Our 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 finish.Defining the Mechanical EnvelopeThe envelope is, of course, largely dictatedby the space available in the system. The slipring engineer should be given the maximumspace available in the system so all existingcandidate designs can be considered. It isimperative that the space required for the slipring be specified in the early stages of thesystem design and that it be consistent withthe structural and electrical demands.Defining System InterfaceRequirementsThe slip ring engineer will need to know thesesystem interface considerations:1. Can the slip ring mount directly on thecenter line or is a through-bore required inthe slip ring? A through-bore can be usedto mount the slip ring on a shaft or used forBasic Slip Ring Design routing hydraulic lines, pneumatic lines, fiberThroughout these pages, you will see optic rotary joint, wave guide. etc.three basic terms used for slip rings: 2. How will the slip ring attach to the system?1. Slip Ring Capsule - A fully integrated A slip ring must be mounted with a flexibleu n i t w i t h a h o u s i n g a n d b e a r i n g s . coupling on one side of the unit. Hard2. Slip Ring Separates - Separate slip ring rotor mounting on both the rotor and stator willand brush blocks for mounting in your system. cause the slip ring to fail prematurely by3. Twist Capsule - A limited rotation device translating system load into the slip ringused typically in scanning applications where bearing structure.3. How should the electrical connections tocontinuous rotation is not required.the 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 exit therotor / stator in a radial or axial direction, andwhat length should the leads be?This 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 application.pay for ten amps continuous capacity whenyou only need two amps.Be aware that voltage surges and spikes arethe major cause of system slip ring failures.Moog uses a conservative approach to circuitdesign, however, it is not uncommon in somepower supply systems to see voltage spikesten or more times the normal operatingvoltage. We strongly recommend surgeprotection on all power supplies.Most 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 projected, if tested for actual values,when data rates, formats and impedancesare defined. The appropriate shieldingtechniques will be incorporated to meet thesystem requirements.Defining Mechanical Requirements1. Operating speed (rpm) 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 excessof 20,000 rpm. The operating speed, inconjunction with the diameter, dictates thesurface speed of the ring relative to the brushand hence the internal design approach andmaterial selection.2. What rotational life is necessary for yourapplication? Will the unit oscillate or rotateat a continuous speed?Defining the EnvironmentThere are two basic slip ring configurationsto consider based on space allocation inyour system:1. The more common drum approachwhere each ring is adjacent to thenext along the centerline, somewhatlike the threads on a bolt and2. The platter approach where the rings areconcentric with one another like the grooveson a flat surface. The pancake approachis used when length is at a premium butdiameter is less restrictive.6Defining Electrical RequirementsThe specified current enables the slipring engineer to propose a unit with theappropriate cross-sectional area of the rings,brushes and lead wires. 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 toThe 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 specified.Your 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 optimum slip ringsolution.Many of the slip ring designs and manufacturing processesdescribed are proprietary and are covered under one ormore U.S., European or Japanese patents.
