IP65 slip rings for flow wrapping machines offer long working life and minimal maintenance
SVTS B series slip ring assemblies from Servotecnica offer machine builders a continuously rotating electrical joint with a working life that can extend to 100 million revolutions at high speeds . The range is aimed at demanding industrial applications in high throughput production machinery where gold alloy multifibre brushes and precious metal rings in IP65 fully sealed ABS / aluminium / stainless steel housings ensure the highly reliable transfer of electrical power and instrumentation signals through rotating structures . A variant , the 70 mm diameter SVTS B 03 , is particularly aimed at transferring power to the rotating heatsealing blades in flow wrapping machines as well as handling temperature signal output to the machine controller .
Available with full sales and technical support from Heason Technology , Servotecnica ’ s UK distribution partner , this variant is equipped with three 400V / 20 A circuits as well as two 240V / 2A signal circuits . Its 22 mm diameter through-hole allows direct mounting on the drive shaft of the rotating blade via four M3 set screws . Available in two versions that facilitate machine washdown use : fully housed and IP65 sealed or part-housed for IP65 when installed - both feature sealed cable gland electrical connection with lower power and customer specified number of slip ring ‘ ways ’ available . Servotecnica ’ s SVTS fibre bundle technology has lower friction and provides exceptionally longer life when compared to the traditional wear-prone carbon brush designs used by other manufacturers .
The multi-fibre bundles require no lubricants and produce only negligible
44 FDPP - www . fdpp . co . uk debris which significantly reduces the need for routine servicing or frequent brush replacement . Highprecision stainless steel support bearings also help ensure long working life and a specified nominal speed capability of 400 rpm enables use on high-throughput machinery . Other benefits include improved signal quality as the ( up-to ten ) individual gold-alloy strand brushes ensure multiple point contact with the slip ring as well as a much higher capacity for handling high transient loads in addition to better resistance to shock and vibration . Other versions of the SVTS - B series have faston-type male terminal connectors where sealing is not required .
Servotecnica ’ s considerable range of slip rings and rotary joints include standard and customised models with specifiable multiple channels for power and signal transmission as well as Ethernet , radio , fibre optic and fluidic transfer – available as housed or part housed , explosion proof , highly ruggedised , open type , and pancake slip ring assemblies . As well as packaging machinery and industrial
manufacturing plant , other industries served include wind turbine , crane & hoist , process control , medical and pharmaceutical production machinery , amusement equipment , machine toolsand more .
Heason Technology is on hand to add machine customisation using Servotecnica ’ s slip ring assemblies . As a systems integrator with its own inhouse design and production facilities and distribution partnerships with selected global automation component suppliers , Heason also supplies and supports motion control equipment from component level to complete systems including stepper and servo motors and drives , motion hardware and software , gear units , linear bearings , mechanical positioning mechanics and more .
