Worm Shaft: Essential Component in Mechanical Systems Introduction to Worm Shafts A worm shaft is a crucial part of mechanical assemblies designed to transmit rotational motion and torque between non-intersecting shafts, typically at right angles. In essence, it consists of a helical screw thread (the worm) meshing with a toothed gear (the worm wheel or worm gear). This arrangement allows for efficient power transmission with a high ratio of speed reduction. Structure and Components of a Worm Shaft The anatomy of a worm shaft comprises several key elements: the worm (a threaded rod or screw), the worm wheel (a toothed wheel), and bearings that support the shaft within the housing.
