Introduction to the Characteristics of Arc Tooth Synchronous Belt Wheel Transmission
Author:
The technical characteristics of the arc tooth synchronous belt wheel drive have been summarized, highlighting the differences between arc tooth synchronous belt wheels and trapezoidal tooth synchronous belt wheels as well as T-type synchronous belt wheels with square teeth. The arc tooth design allows for the transmission of high power, with the power capacity of the transmission system being 3-5 times greater than that of trapezoidal and T-type teeth. It mainly uses soft or medium-hard tooth surfaces, and when using hard tooth surfaces, low-profile teeth are generally preferred. The arc gear transmission is suitable for helical gears but not for spur gears. The relative curvature radius is greater than that of involute gears, resulting in a higher contact strength. When the sensitivity to center distance changes is greater than that of involute gears, the requirements for cutting tooth length are high, and radial variable position cutting is not allowed, allowing for strict control of assembly errors. Arc gears can be classified into single arc gears and double arc gears. Under the same conditions, the contact line strength of single arc gears is higher than that of involute gears, while their bending strength is lower than that of involute gears.
The technical characteristics of the arc tooth synchronous belt wheel drive summarize that the arc tooth synchronous belt wheel differs from the trapezoidal tooth synchronous belt wheel and the T-shaped synchronous belt wheel in terms of square teeth. It can meet the requirements for high-power transmission, with its power capacity being 3-5 times greater than that of trapezoidal and T-shaped teeth. It mainly uses soft tooth surfaces or medium-hard tooth surfaces, and when using hard tooth surfaces, low-profile teeth can generally be selected.

When the sensitivity to center distance changes is greater than that of involute gears, the cutting tooth length requirements are high, and radial variable position cutting is not allowed, allowing for strict control of assembly errors.
