Compared to the simple cylindrical worm drive, the globoid (or throated) worm design significantly increases the contact area between the worm shaft and the teeth of the gear wheel, and therefore greatly improves load capacity and other performance parameters of the worm drive. Also, the...

The wood screw, spurs and cutting edge at the end of the bit would need to be removed as well as the first flight of the auger, which had a shorter pitch. I ground away the bulk of the unwanted material on the bench grinder. The first flight was removed so the remainder of the auger would be of...

A gear is a rotating machine part that utilizes cut teeth, or cogs, to mesh with another toothed part—usually another gear or a linear toothed part (called a gear rack)—to transmit rotational motion and torque. By using a combination of precision gears with the correct ratio, the speed, torque,...

Worm gear units are favoured in general machinery and plant engineering. XL places particular importance on the quality of materials used and thus ensures a: Long service life Above average loadability High performance potential Excellent smooth and emergency running characteristics Minimal...

Best choice of gearing when high drive reduction is required. Worm Wheels resemble spur gears with the addition of a throat cut into the O.D. of wheel. The throat permits the worm wheel to fully envelope the threads of the worm. Threads, not teeth are cut on the worm, and by adjusting the number...

Worm gears are constructed of a worm and a gear (sometimes referred to as a worm wheel), with non-parallel, non-intersecting shafts oriented 90 degrees to each other. The worm is analogous to a screw with a V-type thread, and the gear is analogous to a spur gear. The worm is typically the...
