Study on transmission error of straight bevel gears

Abstract

In a bevel gear, unlike a cylindrical gear, two gears shafts cross, and one of the shafts is basically a cantilever. Therefore, bevel gears are easily influenced by deflections of the gear shafts and bearings. These have a significant influence on transmission error, which produces vibration and noise. Therefore, in considering the deflection of the gear shafts and bearings, obtaining the transmission error of a bevel gear is very important for the design. In this report, transmission error was calculated when gear shafts were supported by two bearings. These calculated values were compared with the transmission error which was calculated without the deflection of the gear shafts and bearings.
