Accuracy Control of Hourglass Worm Gearing. Analysis of Tooth Shape and Tooth Contact.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1998 Feeding under-cutting of Lorentz wheel cutting method of Hindley hourglass worm gearing is analyzed at first. And the shape of the wheel tooth surface is made clear by the analysis and the measuring method of the wheel by 3-dimensional coordinate measuring machine is proposed. Statical and dynamical tooth contact are analyzed to control the accuracy of

Advanced Science, EarlyView.Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

Tooth Contact Analysis and Adjustment Calculation of Real Tooth Surfaces of Hypoid Gears
Jixie chuandong, 2023 For the purpose of adjusting the calculation of the contact pattern of real hypoid gears, the double third-power spline surface is used for fitting tooth surfaces of pinions and gears accurately according to the measurement results of the gear surface. Based on the two-dimension golden section method for increasing the density of gear grid mesh points,

Contact simulation of tooth flanks using Isogeometric Analysis
, 2023 The Finite Element (FE) modelling of a tooth flank affects both the accuracy of the results aswell as the computational time and resources required. In FE Analysis (FEA), the involutecurve is modelled by linear segments, thus deviations from its actual geometry are introduced. In order to achieve accurate results, the mesh must be generated as dense as
