About Boston Gear SH82-P Spiral Bevel Pinion Gear, 2:1
This Boston Gear SH82-P spiral bevel pinion gear has an 8 diametral pitch, 17 case-hardened steel teeth, a 35 degree spiral angle, and a keyway 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 an SH82-G bevel gear for applications requiring a 2:1 gear ratio. It has a keyway and setscrew for use with a 0.750" diameter keyed shaft, is made of low carbon steel (0.2 percent carbon), and has hardened teeth for applications where hardness and strength are 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. The 35 degree spiral angle makes this spiral bevel pinion gear better suited for higher speed and larger torque applications than straight bevel gears. 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 spiral 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 motion between perpendicular rotating shafts. A bevel gear's pressure angle, spiral angle, diametral pitch (also called DP or pitch), and its material are important factors to consider. A bevel gear is part of a set of two gears, and the gear ratio for the set is determined by the number of teeth on each gear. 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 g
