What is the worm drive of a Worm Gearbox and Output Flange?

A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm gear (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm wheel. The terminology is often confused by imprecise use of the term worm gear to refer to the worm, the worm gear, or the worm drive as a unit.

Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. A worm is an example of a screw, one of the six simple machines. One of the major advantages of worm gear drive units are that they can transfer motion in 90 degrees. The worm in the worm gear drive may have single or multiple starts. Each full 360 degree turn of a single start worm advances the gear by one tooth. For a multi-start worm the gear reduction equals the number of teeth on the gear divided by the number of stars on the worm. Both the sliding and the rolling actions of the worm and the gear come into play during the meshing of the gears. The sliding contact dominates at high reduction ratios. Much heat is produced due to friction while sliding, which limits the efficiency of worm gears to 30 to 90 percent. The worm and the gear are made of dissimilar metals in order to minimize friction and loss inefficiency.
