Martin W6D Worm, Double Lead, 14.5° Pressure Angle, High Carbon Steel, Inch, 2.500" Face, 1" Bore Diameter, 2" Pitch Diameter

This Martin worm gear is a right-handed, double-lead worm or "screw" for a worm drive used to increase the torque of a driven shaft. It is made of high carbon steel for tensile strength and hardness. It has a pressure angle of 14.5 degrees for smoother, quieter movement and lower frictional forces. This worm meets American Gear Manufacturing Association (AGMA) standards 6-8 for commercial class gears.Worm gears, also called worm drives, use a long, threaded cylinder called a worm that meshes with the teeth of a worm wheel (similar to a spur gear) to transmit motion. They can be used in a right-angle configuration. The worm wheel is unable to turn the worm, providing a built-in lock or a braking system. They are quieter than spur gears, low maintenance, and suitable in applications that require increased torque and reduced speed, or when changing the rotation direction.Martin Sprocket & Gear manufactures power transmission products, material handling components, and industrial hand tools. The company, founded in 1951 and headquartered in Arlington, TX, meets International Organization for Standardization (ISO) standard 9001:2008.
