Perfection Gear developed a patented industry-leading Swing Drive solution that combines key features of standard slewing gear or rotation bearing and drive systems into a unique fully assembled gearbox that can handle radial or axial loads using high rotational torque. This easy to assemble solution is designed eliminate the common “stick-slip” phenomenon often associated with traditional worm-on-slewing-ring systems.
SW Swing Drive
Double reduction speed reducer with bronze worm gear and pinion
The SW swing drive incorporates the benefits of AT Style worm gear drives with an integral slewing ring. Its design eliminates the common “stick-slip” phenomenon often associated with traditional worm-on-slewing-ring systems. The SW system absorbs higher shock loads and overturning moments compared to traditional worm gear drives.
The patented SW all-in-one package is the best solution for aerial truck applications. It features pre-set backlash, a hydraulically driven input, and minimizes customer interface machining. SW swing drives are readily available in four standard sizes with other sizes available upon request. All SW products can be modified to customer specifications.
