Abstract
Background: Various relevant papers and patents which have reported non-circular gears are widely used in many types of mechanical instruments. The Pascal limacon gear is one new type of noncircular gear. Many researchers have only focused on the design of Pascal limacon gears and their applications. Little attention has been paid to the machining aspects. Shaping is a better method for fabricating non-circular gears. The Equal Rotary-Angle of Workpiece Method (ERAWM), the Equal Arc- Length of Workpiece Method (EALWM), and the Equal Polar-Angle of Workpiece Method (EPAWM) are the three linkage-methods for shaping Pascal limacon gears. However, which linkage-method should be chosen in practical has not been studied.
Objective: In order to choose the excellent linkage-methods for shaping Pascal limacon gears, the three linkage-methods were compared from three aspects: density of shaping cutter trace, uniformity of arc length of program blocks and control of motion axes of machine tools.
Methods: Firstly, the shaping models of Pascal limacon gears was deduced. Secondly, based on the mathematical model, shaping linkage-methods of Pascal limacon gears were obtained. Thirdly, under different shaping linkage-methods, developing regularity of shaping cutter trace, arc length of program blocks and motion axes of machine tools, were compared.
Results: Finally, the excellent shaping linkage-method EALWM is obtained with the characteristics of a high density of shaping cutter trace, high uniformity of arc length of program blocks and ease of control.
Conclusion: It has been proven that EALWM is the best linkage-method to shape Pascal limacon gears.
Keywords: Arc length of program blocks, linkage-methods, motion axes of machine tool, non-circular gears, Pascal limacon gears, shaping, shaping cutter trace.
