    • Mating bevel gears generally include a pinion gear having a body that rotates about an axis and a side gear having a body that rotates about an axis that intersects the axis of the pinion gear. Pinion gear teeth of the pinion gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the pinion gear teeth. Side gear teeth of the side gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the side gear teeth. The curvatures on the pinion and the side gear teeth cooperatively define a controlled relative radius of curvature section except where the involute sections are located. The controlled relative radius of curvature section defines a sum of values of radius of curvature at a point of contact between the curvatures of the pinion gear teeth and the side gear teeth. The sum has a constant or decreasing value.
    • 配合锥齿轮通常包括具有围绕轴线旋转的主体的小齿轮和具有绕与小齿轮的轴线相交的轴线旋转的主体的侧齿轮。 小齿轮的小齿轮齿具有限定曲率的侧面,该曲率具有渐开线部分,俯仰线延伸通过该渐开线部分和小齿轮齿之间的抛物线形状。 侧齿轮的侧齿轮具有限定具有渐开线部分的曲率的侧面,俯仰线延伸通过该渐开线部分,并且在侧齿轮齿之间具有抛物线形状。 小齿轮和侧齿轮齿上的曲率协调地限定了可控的相对曲率半径部分,除了渐开线部分所在的区域外。 受控的相对曲率半径部分限定了小齿轮齿和侧齿轮齿的曲率之间的接触点处的曲率半径的总和。 总和有一个常数或减少的值。

    • A method for trimming a single book having a front edge and two side edges includes transporting a book in a transport direction so that the front edge is parallel to the transport direction, cutting the front edge of the book using a first reciprocating knife when the front edge is parallel to the transport direction, transporting the book so that the side edges are parallel to the transport direction, and cutting the side edges using second and third reciprocating knives when the side edges are parallel to the transport direction. A single book trimming device is also provided having a conveyor device for conveying a book in a transport direction, a reciprocating front knife for trimming a front edge of the book, the front knife having a first blade edge parallel to the transport direction of the conveyor at the front knife; and at least one reciprocating side knife for trimming side edges of the book, the side knife having a second blade edge parallel to the transport direction at the side knife.
