Implementation of the Spur Involute Gear Model on Modelica
A procedure to build up a dynamical model of the gearbox with spur involute mesh is being described. The main attention is paid to the design technology of the cylindrical bodies elastic contact models. To track geometry of contact implicit equations of algebraic/transcendental or differential-algebraic type are being used. At the same time dynamical models of the bodies involved, gearwheels an...
متن کاملSliding Friction Contact Stiffness Model of Involute Arc Cylindrical Gear Based on Fractal Theory
Gear’s normal contact stiffness played an important role in the mechanical equipment. In this paper, the M-B fractal model is modified and the contact surface coefficient is put forward to set up the fractal model, considering the influence of friction, which could be used to calculate accurately the involute arc cylindrical gears’ normal contact stiffness based on the fractal theory and Hertz ...
متن کاملA New Method to Calculate Bending Deformation of Involute Helical Gear
The traditional method to calculate bending displacement of helical tooth is generally based on simplified tooth profile. Besides, the unbalance loading is not taken into account. To overcome this disadvantage, a new method to calculate bending deformation of helical tooth is introduced. First, gear section is divided into several copies along tooth width and each section’s moment of inertia is...
متن کاملResearch on the Tooth-Surface Controlling and Honing Machining of the Ultral-Precision CBN Gear
With the popularization of precision-machining process by the hard tooth-surface gear, special machining tools have also been developed rapidly, which is mainly manifested in as aspects as the application of new materials and cutting tools’ coating technology, the mature of ultra-hard-grain CBN tools’ preparation technology, and the pefecting day by day of tool-structure design and tool-integra...
متن کاملA Novel Artifact for Evaluating Accuracies of Gear Profile and Pitch Measurements of Gear Measuring Instruments
− Evaluation of measurement performance of a gear measuring instrument (GMI) is not easy task since a master gear with sufficient accuracy has not been available. The manufacturing the master gear with an ideal involute form is very difficult and the accuracy of the master gear is not able to be estimated. Therefore, we have proposed a new artifact named Double Ball Artifact (DBA) which consist...
