The most significant difference between the worm gear and a conventional gear set is the type of lubricant used in the worm. Worm gears require much more lubrication than conventional gearsets because they interact through sliding rather than rolling components. Worm gears are therefore more prone to sliding wear than other gear types. It is therefore important to choose the proper lubricant for your gear set.
RV reducers NMRV worm gearboxes made of aluminum alloy are ideal for cold climates as they do not have EP complications. Polyalkylene glycols are suitable for low temperatures but may not be compatible with some seals or paints. Aluminum worm gearboxes come at competitive prices. They feature an easy-to-use backlash adjustment. In addition, the gearbox has a larger application field than other types of gearboxes.
