20.500.12556/RUL-130970 Basic theory and design method of variable shaft angle line gear mechanism Osnovna teorija in metoda za konstruiranje linijskih zobniških mehanizmov z variabilnim kotom gredi In this paper, a novel line gear mechanism is proposed; it is called the variable shaft angle line gear mechanism (VSALGM). VSALGM has two rotational degrees of freedom, one is the rotation of the two gears with a constant transmission ratio, and the other is the relative swing of the two gears shafts. First, a novel contact model of VSALGM composed of one driven contact curve and one driving line teeth working surface (DLTWS) was proposed. With the concept, the basic design equations for VSALGM were derived on the basis of the space curve meshing theory of line gear. Moreover, the design criterion of pressure angle for VSALGM was analysed and proposed on the basis of the contact model. A basic design method for VSALGM was thus developed. A design example was given, and prototypes were manufactured using three-dimensional (3D) printing. Kinematic experiments and gear contact spot testing were carried out on a self-made kinematic test rig by the prototypes. The results show that the VSALGM designed in this paper can achieve a continuous, smooth and stable meshing transmission while the shaft angle is continuously changed within its setting range. line gear variable shaft angle degree of freedom pressure angle space curve meshing theory linijski zobniki variabilen kot gredi prostostna stopnja ubirni kot teorija prostorske ubirnice kinematični eksperiment zobniški prenos true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-20 09:06:27 2021-09-20 09:06:30 2022-09-10 04:09:07 0000-00-00 00:00:00 2021 0 0 Str. 352-362 no. 7/8 Vol. 67 Jul.-Aug. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.8(045) 0039-2480 10.5545/sv-jme.2021.7216 76894723 RAZ_Chen_Yang-zhi_2021.pdf RAZ_Chen_Yang-zhi_2021.pdf 1 EBB38E8E22F3A749FEE940E4D41F6866 aea4767bab8534221bbd8e82fdf240a7197678882b4990c6d23d1297b6737eda b8bc1b25-19e1-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148174 https://www.sv-jme.eu/sl/article/basic-theory-and-design-method-of-variable-shaft-angle-line-gear-mechanism/ 1 04b6f31a-19e1-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148173 Fakulteta za strojništvo Strojniški vestnik 0 0 0
