face tooth
5.The main research results are as follows:The friction contact between teeth in the tooth-locked quick closure device is studied, and the simulation is made to the contact conduct between the teeth utilizing the face to face contact model with contact element and coulomb friction model, the whole finite element model of tooth-locked quick closure device is created.
6.By considering the contact between the teeth and utilizing the face to face contact model with contact element and coulomb friction model, the author had developed a method for design of tooth-locked quick actuating pressure vessel based on finite element stress analysis and stress categorization.
7.By considering the contact between the teeth and utilizing the face to face contact model with contact element and coulomb friction model, the author have developed a computing method for plastic load of tooth-locked quick actuating pressure vessel based on finite element stress analysis and stress categorization.
8.Taking gear without tooth face invalidation such as agglutination and abrasion as a precondition, and according to the relation between minimal oil film thickness and tooth face roughness of elastic liquid dynamic pressure lubrication theory, viscosity of gear lubrication oil was educed by reliability method in this paper, and the calculation formula has been elicited and applied.
