ASSISTED DESIGN OF THE WORM-GEARING USING RIGIDITY VARIATION CRITERION
Daniela GHELASE, Luiza DASCHIEVICI, Constantin DOGARIU
Abstract: The paper presents some aspects regarding the achievement of a worm-gearing tooth with a constant rigidity. When we want a constant rigidity at which the values for amplitude are as low as possible, we refer to performing a rigidity curve with short jumps, as flattened as possible. The theory of vibrations shows that a rigidity characteristic with jumps represents an interne source for the excitation of the gear drive. So, reducing the amplitude it is obtained a smooth meshing, because the magnitude of the vibrations and noise will become lower. It is obvious that the reduction of amplitude of rigidity curve is another mode to obtain high rigidity for the gearing tooth.
Key words: optimal design, worm-gearing, numerical method, amplitude, rigidity, computer simulation, meshing.
