Key Features

  • Left hand spiral miter 90 degree mesh transmits mechanical power between perpendicular shafts
  • Spiral angle of 35 degrees better suits this spiral miter gear for higher speed and larger torque applications than straight miter gears
  • 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
  • Hardened teeth for 1:1 gear ratio applications where hardness and strength are needed to transmit torque and motion
  • Bore has keyway and setscrew for use with keyed shaft

Product Description

This high carbon steel Boston Gear HLSK-L series spiral miter gear has a 20 degree pressure angle (PA) and a left hand 35 degree spiral angle to transmit torque between perpendicular shafts to provide rotational power to another part of a motorized system. This gear has a keyway and setscrew for use with a keyed shaft, is made of high carbon steel for tensile strength, and has hardened teeth for 1:1 gear ratio 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 14.5 degree pressure angle, resulting in higher load capacity. The 35 degree spiral angle makes this spiral miter gear better suited for higher speed and larger torque applications than straight miter gears. 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 Boston Gear 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.

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.
