Meshing mechanism considering various combinations of assembly and manufacturing errors on face gear using a transmission-error-controlled curve

Abstract

A face gear is typically used in fishing spinning reel mechanism owing to its easy fabrication and good reel handle rotation. As face gears without tooth flank modification are sensitive to assembly errors, the fishing reel sensation becomes unstable in mass production. Previously, tooth flank modification with a transmission error (TE)-controlled curve was used to solve this problem. The TE-controlled curve stabilized the fishing reel sensation for assembling. However, in mass production, the manufacturing error of a pinion and face gear must be considered along with the assembly error. In a previous study, we analyzed all the eight error factors, including the manufacturing error, individually. Thus, we clarified that pressure angle deviation of the pinion and tooth rotational error of the face gear have a significant effect on TE. However, in mass production, these errors are combined in a complicated manner. In this study, an experiment was conducted using the L18 orthogonal array to elucidate the interaction between error factors.
