Boston Gear H3222 Spur Gear, 14.5 Pressure Angle, Steel, Inch, 32 Pitch, 0.250" Bore, 0.75" OD, 0.188" Face Width, 22 Teeth

Model: H3222   |    Mpn: H3222   |    Ean: 0781711095423   |    PartNumber: H3222   |   Asin: B004N631OE

The Boston Gear low carbon steel spur gear with 14.5-degree pressure angle (PA) and a diametral pitch (DP) of 32 transmits torque between parallel shafts to provide rotational power to another part of a motorized system. It has a 14.5-degree pressure angle for a higher contact ratio between gears than larger pressure angles, resulting in quieter operation, and a 32-diametral pitch for applications for applications where controlling changes in speed and direction of rotation with precision is more important than transferring torque. This spur gear, which can mesh only with spur gears that have the same pressure angle and diametral pitch, is made of low carbon steel (.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion. This Boston Gear spur gear is suitable for use in a variety of commercial and industrial applications, such as construction equipment, aeronautics, conveyors, and manufacturing equipment, among others.

Spur gears, the most common gear type, have a circular or cylindrical shape with teeth bordering the outer perimeter and are used for transmitting rotational torque and motion between parallel rotating shafts. A spur gear's pressure angle (PA), 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 bevel and miter gears (for rotating shafts perpendicular 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.

Boston Gear manufactures a variety of gear drives, variable speed drives, clutches, and the components that comprise these systems including sprockets and bearings. Their manufacturing designs, production, and inspection meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1877, is headquartered in Charlotte, NC.

Features

  • Transmits torque between parallel shafts to provide rotational power to another part of a motorized system
  • Pressure angle of 14.5 degrees for a higher contact ratio between gears, resulting in quieter operation than larger pressure angles
  • Diametral pitch of 32 for applications where controlling changes in speed and direction of rotation with precision is more important than transferring torque

Boston Gear SH142-1P Spiral Bevel Pinion Gear, 2:1 Ratio, 0.500" Bore, 14 Pitch, 16 Teeth, 35 Degree Spiral Angle, Keyway, Steel with Case-Hardened Teeth

Model: SH1421P   |    Mpn: SH1421P   |    Ean: 0781711119082   |    PartNumber: SH1421P   |   Asin: B004N62QRW

This Boston Gear SH142-1P spiral bevel pinion gear has a 14 diametral pitch, 16 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 SH142-1G bevel gear for applications requiring a 2:1 gear ratio. It has a keyway and setscrew for use with a 0.500" diameter keyed shaft (not included), 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 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.

Boston Gear manufactures gears, gear drives, bearings, valves, shaft collars, couplings, and other power and fluid transmission components. The company, founded in 1877, is headquartered in Charlotte, NC, and meets International Organization for Standardization (ISO) standard 9001:2008 standard.

Features

  • 16 teeth for use with SH142-1G mating bevel gear in 2:1 gear ratio applications
  • Spiral bevel 90 degree mesh transmits mechanical power between perpendicular shafts
  • Spiral angle of 35 degrees better suits this spiral bevel gear for higher speed and larger torque applications than straight bevel gears
  • Low carbon steel (0.2 percent carbon) for applications where the hardness and strength of higher levels of carbon are not needed to transmit torque and motion
  • Case-hardened teeth for applications where hardness and strength are needed to transmit torque and motion
