Abstract
This paper gets the inspiration from the tooth form of the ordinary straight bevel gear the equiconjugate of curvature and the double-circular-arc of the spiral bevel gear, then proposes high degree contact with the equiconjugate of curvature straight Bevel Gear. The tooth form of this gear is f-shaped, whether the contact strength of the tooth flank or the bending strength of the gear tooth all higher than the involute gear and the double-circular-arc gear, and it can carrying more capacity, have a high practical value.
Even in the modern time ,the electrical, NC technology highly developed, the gear still occupies an important position. However in our country the circarc gear in used and development, mainly refers to the cylindrical gearing, and the arc tooth for spiral bevel gear Drive, has few results. So the f-saped Bevel Gear Gear superior than the spiral, straight Bevel Gear and it is attention to the application being gradually, its practical value are higher and higher, the study on the Straight Bevel Gear are more and more intensive.
Key words: high degree contact straight tooth bevel gears mesh f-shaped
