Abstract: Several embodiments of various non-involute gear tooth profiles incorporate relief areas formed across the area of the tooth face generally symmetrically to each side of the pitch circle of the gear. The relief area serves to preclude contact across the areas of meshing or mating gear teeth where convex-to-convex contact would otherwise occur, thus precluding high pressure contact between the two gear teeth at the area of the relief. The remainder of the contact of such non-involute gear tooth profiles provides conformal contact, i. e., convex-to-concave mating faces with correspondingly low pressures developed between the tooth portions. The present invention enables a given gear set to absorb considerably greater torque and force than would otherwise be they case, or alternatively allows gear sets to be made considerably smaller and lighter for a given torque transmission, than would otherwise be the case.

Abstract: A form of gearing having teeth with different face widths along the tooth height and a method thereof of designing and manufacturing. Different gear tooth face widths are introduced along the tooth height to alter the tooth stiffness characteristic to provide a pair of gears with reduced mesh stiffness variation. The use of variable face widths along the tooth height changes both the geometric properties of the tooth and the load distribution/concentration to reduce the self-excited component of dynamic load, in effect reducing gear noise and increasing power density.

Abstract: A hypoid gear set including a ring-shaped gear positioned about an axis and having a plurality of curved gear teeth arranged about the axis. Each tooth has a second side having a forward face with a shallow pressure angle relative to an axially extending line and defining the drive side of the gear. Each tooth has a first side having a rear face with a steep pressure angle relative to an axially extending line and defining the coast side. A pinion gear drives the rear faces of the ring-shaped gear such that the ring-shaped gear rotates in the direction of the forward faces of the teeth of the ring-shaped gear.

Abstract: A hollow rack shaft is produced by forming a plate work piece and has continuous metal flow along the contour of rack teeth surface without being cut. A series of wave-like concave-convex sections is formed on the inner surface of the shaft. Thickness of tooth body and tooth bottom of the rack teeth is adjusted by dimensions of the unevenness. Thereby, stress concentration at each point of the rack shaft is prevented and the shaft is strengthend and lightweightized.

Abstract: The present invention provides an advanced geometry for skew and straight bevel gears having a localized and more stable bearing contact produced by forging. The localization of bearing contact is achieved by substitution of flat tooth surfaces with parabolic tooth surfaces. This is accomplished by either modifying line-contact directly or by using a generating parabolic cylinder during generation of the tooth surfaces. The actual contact area is spread over an ellipse centered around an instantaneous theoretical point of contact at the apex of the parabolic tooth surface. This localized bearing contact reduces the shift of the bearing due to assembly and manufacturing errors, thereby providing a more durable and quieter gear. Furthermore, the geometry of the gear enables creation of dies from which the gear may be forged. Transmission errors are modeled using a pre-designed parabolic function that coincides with the parabolic tooth surface design of the present invention.

Abstract translation: 本发明提供了一种用于偏斜和直锥齿轮的先进几何形状，其具有通过锻造产生的局部和更稳定的轴承接触。 轴承接触的定位是通过用抛物面齿表面代替平齿表面实现的。 这可以通过直接修改线接触或者在牙齿表面的产生期间使用产生抛物线的圆柱来实现。 实际的接触面积分布在以抛物面齿面顶点的瞬时理论接触点为中心的椭圆上。 这种局部轴承接触减少了由于组装和制造误差导致的轴承偏移，从而提供了更耐用和更安静的齿轮。 此外，齿轮的几何形状能够形成可以锻造齿轮的模具。 使用与本发明的抛物面齿面设计一致的预先设计的抛物线函数建模传输误差。
