What is a circular arc gear?
Author:
Arc gears: Gears with an arc-shaped tooth profile that engage at points. Arc gear transmission typically has two engagement forms: the pinion has a convex arc tooth profile, while the gear has a concave arc tooth profile, known as single arc gear transmission. In the research of modern gear reduction motors, arc gears are set to replace cylindrical gears as the focus of development. In terms of stability, torque, and service life, arc gears have significant advantages over cylindrical gears, and their development trend is also promising. In China, single arc gear transmission has been used in high-speed heavy-load equipment such as steam turbines, compressors, and low-speed heavy-load rolling mills; double arc gear transmission has been used in the main drive of large rolling mills.
