Intelligent worm gearbox fault diagnosis under various

Worm gears are subject to a rate of wear which is much higher than that might be expected in conventional gear systems. The high degree of sliding present between a hard steel worm and a softer worm wheel, the softer wheel component is subject to wear due to the sliding action of the worm over its surface. As the degree of wear on wheel tooth geometry increases, the effective contact area

Making Worm Wheels on the Lathe

If the wear point is at the bottom of the hollow, the worm will tend to wear further into the wheel which, according to my half-baked reasoning, could eventually cause the reduction of wheel radius and eventually perhaps a reduction in tooth count, just as is observed when making the first and second pass of the tap around the wheel when hobbing. Here is a table of some common sizes that I

Basic Gear Mechanisms : 21 Steps (with Pictures

A worm gear is a gear driven by a worm, which is a small, screw-like piece that meshes with the gear. The gear rotates on an axis perpendicular, but on a different plane than, the worm. With each rotation of the worm, the gear rotates by one tooth. This means that the gear ratio of a worm gear is always N:1, where N is the number of teeth the gear has. While most gears have circular pitch, a
