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 ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...
