【Abstract】 An experimental investigation on vibration and noise is made in spur gear transmission. The spur gears are modified with three different profile modification parameters. The results of gear transmission test indicate that the low vibration and noise can be achieved with following modified spur gears,i.e. the designed gears with modified profiles can avert meshing interference caused by manufacturing errors and the fluctuation of its static transmission errors are kept within a narrow range.更多还原
