Martin B1020-3 Bevel Gear, 20° Pressure Angle, Cast Iron, Inch, 0.780" Face, 3/4" Bore Diameter, 2 Pitch Diameter, 2.27" Outer Diameter, 20 Teeth

Key features

• For use with its mating bevel gear in the appropriate gear ratio applications
• Straight bevel 90 degree mesh transmits mechanical power between perpendicular shafts
• Pressure angle of 20 degrees for a lower contact ratio between gears, resulting in higher load capacity than smaller pressure angles
• ASTM A48 Class 30 gray cast iron for resistance to wear, corrosion, and galling
• Unhardened teeth for applications where hardness and strength are not needed to transmit torque and motion

This Martin bevel gear is made of cast iron, has a 20 degree pressure angle, and has a straight bevel to transmit torque between perpendicular shafts to provide rotational power to another part of a motorized system. This bevel gear is intended for use with its mating bevel gear to achieve a desired gear ratio. It has a plain bore, is made of ASTM A48 Class 30 gray cast iron for resistance to wear, corrosion, and galling, and has unhardened teeth for applications where hardness and strength are not needed to transmit torque and motion. The 20 degree pressure angle provides a lower contact ratio between gears than a smaller pressure angle, resulting in higher load capacity. This gear is used only with its mating gear because bevel gears can mesh only with gears that have the same pressure angle, spiral angle, and diametral pitch (that is, the number of teeth per inch). This Boston Gear bevel gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.Bevel gears have a blunt-end cone shape with teeth along the cone face and are used for transmitting torque and motio
