About Worms and Worm Gears

Worm gears are cylindrical gears with a spiral thread that drive mating worm wheels in high-reduction gearset applications. They operate on non-intersecting perpendicular axes. Worm gears are widely used for speed reduction or increase, torque multiplication and resolution, and accuracy enhancement for positioning systems. Worm gear drives provide substantial speed reduction and torque multiplication in a comparatively small design package.

Products & Services Related to Worms and Worm Gears

Bevel and Miter Gears

Bevel and miter gears have conical faces that operate on intersecting axes. Miter gears are bevel gears with a 1:1 ratio operating on right axes.

Gears

Gears are mechanical devices that transmit power and motion between axes.

Helical Gears

Helical gears transmit power and motion between parallel axes (opposite hand) or right-angle axes (same-hand).

Hypoid Gears

Hypoid gears have specially formed teeth on a circular face that are driven by a worm-like drive on non-intersecting axes.

Metric Gears

Metric gears are defined by module, which designates the center-to-center distance between successive teeth.

Rack and Pinion Gears

Rack and pinion gears are used to convert rotation into linear motion.

Spur Gears

Spur gears are straight-toothed gears with radial teeth that transmit power and motion between parallel axes.
