Designing Multispeed Gear Pitch Curves

Abstract:

As special mechanical systems within transmissions of unconventional motions, noncircular gears still offer multiple research opportunities due to their various geometries and kinematics characteristics. Investigation on noncircular gears highlights the lack of information on gears with combination of constant and variable speed, also named multispeed gears, recommended for industrial applications that require uniform speeds for different parts of a cycle, with a smooth transition between the parts. Therefore, in this paper the design of multispeed gears pitch curves is taken into account, as the first important step in the gear design procedure. Specific original algorithms are dedicated to multispeed gear pitch curve modeling, based on the definition of gear transmission ratio variation law. The next step of the multispeed gear design, the teeth generation, accessible through solid modeling or analytical procedure, will be approached in a future study.
