POWER TRANSMISSION COMPONENTS Motor uses hybrid technology With a hybrid motor design the BALDOR ELECTRIC CO RPM XE platform is available in two design configurations a power dense and standard NEMA frame The standard NEMA offers a drop in replacement solution for traditional induction motors The motor starts like a traditional design B induction motor and pulls into true synchronous speed operating as a true synchronous machine The power dense design offers horsepower in a smaller frame best suited when the driven equipment or machine is limited on space The laminated finned frame construction also contributes to power density and enhanced thermal performance by providing greater heat dissipation which results in cooler operation and longer motor life www baldor com Roller bearings help extend service life Made from high quality steel the SKF Explorer spherical roller bearings for vibratory applications benefit from an upgraded heat treatment and special cage design Typical applications include vibrating screens compactors road rollers and similar end uses operating with high vibration and exposed to contamination and or poor lubrication conditions The bearings are designed to accommodate heavy radial and axial loads suiting applications where misalignment or shaft deflections may occur The bearings are available in a range of bore sizes with increased dimensional precision two hardened steel cages with an outer ring centered guide ring and C4 internal radial clearance standard www skf com Wedge link belting offers narrow design With a narrow profile FENNER DRIVES wedge link belting has applications for the metals production cement mining forestry and aggregate industries Profiles include 3V 5V SPZ SPA and SPB The 3V and 5V link belts provide a way to get the benefits of link belting on wedge belt drives The products individual polyester polyurethane link design enables belts to be made to any length on site by hand The modular method of construction eliminates the need for inventories of conventional belts Assembly consists of reeling off the required lengths of belting and utilizing the twist lock design to complete the new belt www fennerdrives com Coupling manages torsional vibration in drivetrains REGALS POWER TRANSMISSION SOLUTIONS Kop Flex MAX C WB coupling serves as a solution for managing torsional vibration in high performance drivetrains powered by synchronous motors variable frequency drives and diesel engines The couplings design combines a maintenance free non lubricated MAX C WB resilient coupling half with a lightweight diaphragm disc or high performance gear coupling half The design combines the advantages of a low cost lightweight flexible coupling half for the driven shaft with vibration damping of a MAX C WB coupling half on the motor end The MAX C WB works well with drivetrains for ID FD fans torque converters marine gears drill rigs crushers kiln drives mill pinions and feed rolls www regalbeloit com 28 PIT QUARRY February 2018 pitandquarry com
