Boston Miter Gears are designed for the transmission of motion and power between two intersecting shafts positioned at a right angle. Miter Gears are similar to Bevel Gears except Miter Gears are used for 1:1 ratios. Straight tooth Miter Gears are cut with a generated “Coniflex” tooth form providing increased life and quieter operating conditions. Spiral tooth Miter Gears are better suited for higher speeds and high torque applications.
