Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2001 A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the modified tooth geometry, which ensures that the worm gear teeth are in localized contact.

Load Tooth Contact Analysis for Arc Tooth Face Gear Considering Assembly Misalignment
Jixie chuandong, 2015 The generating method is adopted for processing arc tooth face gear to ensure the meshing precision of arc tooth face gear pair. The tooth face contact model is established with assembly misalignment. By application of the elastic contact mechanics,finite element influence matrix method and mathematical programming method,the load tooth contact ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Periodontitis treatment and microbiome in a patient with FAM20A mutation: Case study of 1.5 years
Clinical Advances in Periodontics, EarlyView.Abstract Background Enamel‐renal‐gingival syndrome (ERGS) is an autosomal recessive disorder caused by mutations in the FAMily with sequence similarity 20A (FAM20A) gene, and is characterized by amelogenesis imperfecta, delayed or failed tooth eruption, and periodontitis.

Effect of extended tooth contact on the modeling of spur gear transmissions [PDF]
In some gear dynamic models, the effect of tooth flexibility is ignored when the model determines which pairs of teeth are in contact. Deflection of loaded teeth is not introduced until the equations of motion are solved.
