Power Transmission

Micron EverTrue planetary gearheads are designed for high speeds, long life, and continuous-duty operation.

The EZSplice strand is designed to simplify the joining and splicing of continuous-loop conveyor belts.

HG+ right-angle gearheads provide an efficiency above 96% with guaranteed backlash of less than 4 arc-min, ratios of i = 3–10, and an acceleration torque of 20 to 640 Nm.

A seven-speed automatic transmission, said to be the world's first, makes its debut in select V8-powered Mercedes-Benz vehicles.

Elastic spacers that separate recirculating balls inside ball-screw nuts improve fine and slow motion.

Posidyne X Class oil-shear clutch/brakes come in four models to fit drives up to 10 hp with torque ratings from 100 to 1,000 lb-in.

The VMaster line of viscous air-sensing fan drives now includes firstfit and aftermarket applications.

A new series of straight (SA) and tapered-bore (TA) tension-control brakes from Nexen Group Inc., Vadnais Heights, Minn. ,feature finned rotors for cooling and hightemperature O-rings and bearings, which let the brakes run at maximum thermal capacities.

Accu-gear helical gearboxes from Candy Controls provide up to 40 Nm of continuous torque, 120-Nm peak torque, and will accept input speed to 10,000 rpm.

A prototype belt-slicing machine built from ready-to-go automation components boosts timing-belt production sixfold compared with manual methods.

The RGS rapid guide screw hits speeds to 60 ips, rivaling belts and cables and offering better positioning accuracy, repeatability, and axial stiffness.

Rosta heavy-duty (HD) tensioners self-adjust to correct for belt slippage and stretching, maintaining proper tension in multigroove V-belt drives.

Researchers at Lawrence Berkeley National Laboratory transformed carbon nanotubes into conveyor belts capable of ferrying atomsized particles to microscopic worksites.

Design enhancements improve efficiency and eliminate leaks.

Researchers at Southwest Research Institute (SwRI), together with an Asian automaker, have developed an automated manual transmission that merges the convenience of an automatic with the fuel and weight savings of a manual.
