Abstract The alignment deviation of the V-vertex two symmetrically arranged gears with different rotation directions is a unique geometric parameter double helical gears, which has an important effect on vibration, noise, and gear service life. Aiming to more accurately represent manufacturing accuracy their transmission performance, this paper proposes meaning v-vertex basis contact line tooth...

Studying gear power loss theoretically and determining the efficiency of a helical drive depend on many geometrical working parameters, such as rotation speed, tooth number, ratio, helix angle, torque, among others. In this paper, Plackett–Burman screening design Box–Behnken response-surface method are used to consider how above parameters influence efficiency, experimental models provided eval...

Researchers must review numerous standardized criteria that determine the design of mechanical transmissions with gears in order to keep up current developments engineering practice. In classical there are various standards concerning calculation load capacity spur and helical gears. Both them further used evaluate state stress due bending tooth. There many for calculating traditional design. a...

Abstract The helical gear pair is widely used in different mechanical constructions such as vehicle industry and working machine industry. main property of them the skew tooth direction with which better connections could be available than case straight direction. analysis effect addendum modification coefficient for normal stress deformation aim research determined by finite element analysis. ...

The accuracy of gear meshing efficiency model is the key to study influence factors efficiency. Experiment an effective method verify theory model. Therefore, acquisition experimental value particularly important. Taken double helical gears as research object, on analysis a large number data, for are calculated and then rotational speed torque studied. Firstly, calculation transmission in diffe...
