Product Description

This Martin worm gear is a right-hand, single-thread gear for a worm drive to increase the torque of a driven shaft. It is made of American Society for Testing and Materials (ASTM) A48 Class 30 gray cast iron for resistance to wear, galling, and corrosion on. It has a pressure angle of 14.5 degrees for smoother, quieter movement and lower frictional forces. This gear 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.
