he 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.
