Product Description
This high carbon steel Martin miter gear has a 20 degree pressure angle (PA) and a straight miter to transmit torque between perpendicular shafts to provide rotational power to another part of a motorized system. This gear is made of high carbon steel for tensile strength. The 20 degree pressure angle provides a lower contact ratio between gears than a 14.5 degree pressure angle, resulting in higher load capacity. This gear is intended for use only with identical gears because miter gears can mesh only with gears that have the same pressure angle, number of teeth, and diametral pitch (number of teeth per inch). This Martin miter gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.
Miter gears have a blunt-end cone shape with teeth along the cone face and are used for transmitting torque and motion between perpendicular rotating shafts. A miter gear's pressure angle (PA), spiral angle, diametral pitch (also called DP or pitch), and its material are important factors to consider when purchasing. Gears come in several types for use in different power transmission configurations and for different applications, including spur gears (for rotating shafts parallel to each other), change gears (to increase or decrease torque and speed), helical gears (for high rates of rotational speed), internal gears (where one gear is nested inside the other), rack and pinion gears (for turning rotational motion into linear motion), and worm gears (for perpendicular shafts in tight spaces and quiet operation). Gears are suitable for use in the agriculture, automotive, construction, mining, and packaging industries, and can be found in a variety of machines, including bicycles, automobiles, and elevators, among others.
Martin Sprocket and Gear manufactures a variety of mechanical power transmission products such as sprockets, gears, bearings, and pulleys that meet International Organization for Standardization (ISO) standards for design and production. The company, founded in 1951, is headquartered in Arlington, TX.
