Slew Drive Manufacturers and Suppliers
A Slew Drive is a type of gearbox that is specifically designed to handle high radial, axial, and moment loads. They are designed to withstand hold loads while also providing high rotational output torque. Slew drives consist of a worm gear mechanism, a metal bearing component, rubber seals, and sturdy housing to prevent environmental factors such as dirt, water, and dust from destroying the working components of the drive Slew drives operate fundamentally identical to worm gears. As a worm gear rotates, it translates rotational motion along its axis to rotary motion of the axis it is perpendicular to. The driven member (the worm wheel) consequently exhibits a decrease in speed and a proportional increase in torque from the worm gear. The output speed of the worm wheel is dependent upon the ratio of the threads on the worm gear to the number of teeth on the worm wheel
