Boston Gear ND14B 1 Pressure Angle Review

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 12 for applications requiring a balance between transferring torque and controlling changes in speed and direction of rotation with precision. 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.
