Worm Gear Drives

David Brown worm gear drives provide our customers with the ideal way to reduce speed in a minimum amount of space. Our worm gear drives can be mounted in the 'worm under', 'worm over' and gear shaft vertical mounting positions and provide a choice of shaft arrangements.

The David Brown worm gear range comes in Single Reduction worm gears which are based on a single universal case for each size, giving a high degree of common parts and interchange ability. Our Double Reduction worm gears are ideal for fitting to slow moving machinery and are constructed using two single reduction worm gear units connected together.

David Brown worm gears are also available for washdown environments and can also be shaft mounted units which are directly mounted to the driven shaft dispensing with connecting couplings and baseplates . The standard and Heavy Duty worm gears are ideal for stirrer and cooling tower units where a larger lower bearing and increased shaft size are needed to add extra unit capacity and absorb higher shaft and bearing loads.
