摘要： Noise can be effectively reduced without rotative power transmission accuracy being compromised.In a tooth 2 of a resin gear 1, a tooth face that is a predetermined area from a tooth crest 8 towards a tooth root 10 side serves as a tooth profile modification area 11. A tooth surface excluding the tooth profile modification area 11 serves as an involute profile area 12. The tooth profile modification area 11 includes a linear standard profile portion 14 formed by an involute curved line from the tooth crest 8 of the tooth towards the tooth root 10 side and a profile modification portion 16 in which a tooth thickness gradually and smoothly decreases from the standard profile portion 14 along a tooth width direction and the tooth thickness gradually and smoothly decreases from a tooth root end side 15 towards the tooth crest 8. In the tooth profile modification area 11, a contacting section becomes elastically deformed as a result of the resin gear coming into contact with a meshing mating gear. A tooth width direction length of the contact surface gradually increases from a minute, point-like width to a full tooth width from the tooth crest 8 side towards the tooth root 10 side.

摘要： 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.

摘要翻译： 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。

摘要： A curvature of a locus of contact points at a higher torque value is increased such that the torque-dependent characteristic of the working transmission error assumes a minimum value in the vicinity of a working torque value T.sub.1 at the tooth surface position corresponding to the working torque value T.sub.1, in the vicinity of a working torque value T.sub.3 at the tooth surface position corresponding to the working torque value T.sub.3, and in the vicinity of a working torque value T.sub.5 at the tooth surface position corresponding to the working torque value T.sub.5. As a consequence, the change in the working transmission error at the working torque is minimized making it possible to reduce the working transmission error in a wide working torque range.

摘要： Since the true power density of gearing is a function of the dynamic load, maximization of this critical performance property can be achieved only if both the static component and the dynamic increment of load are minimized. The invention discloses how these two objectives may be achieved in the same gear set. Both static and dynamic tooth stresses are minimized by forming the gears to have an optimum load distribution, a feature realized by using a new type of modification that minimizes the tooth surface relief area. The second requirement, of minimizing the dynamic increment, is accomplished in helical and spiral bevel gearing by proportioning the teeth to have a fully elastic "self-complementary" tooth pair stiffness curve, which gives a mesh stiffness characteristic that remains substantially constant throughout the entire tooth pair engagement angle at all loads and all speeds.

摘要翻译： 由于齿轮传动的真实功率密度是动态载荷的函数，所以只有当静载分量和载荷的动态增量都最小化时，才能实现该关键性能特性的最大化。 本发明公开了如何在相同的齿轮组中实现这两个目标。 通过形成齿轮以实现最佳的负载分布，使静态和动态齿应力最小化，这是通过使用最小化牙齿表面起伏区域的新型修改实现的特征。 最小化动态增量的第二个要求是通过将齿配比来实现螺旋和螺旋锥齿轮传动，以具有完全弹性的“自互补”齿对刚度曲线，其提供了在整个整体中保持基本恒定的网格刚度特性 所有载荷和所有速度下的齿对啮合角度。

摘要： A new system of modifications for power train gearing, called "differential crowning," has both advantages and disadvantages over the previous system of modifications based on tip and/or root relief. The advantages of differential crowning are three-fold: (1) it affords substantially constant stiffness, so that it is equally effective at all loads; (2) it is adapted to minimize both first and second harmonic excitations, whereas conventional modifications can mitigate only the first harmonic excitation, and that only at one "design load;" and (3), it is as insensitive to manufacturing inaccuracies as conventional gearing is sensitive to them. Differential crowning, however, has two disadvantages in its previously disclosed forms: (1) it is difficult to optimize; and (2), it is more expensive than conventional modifications unless the production runs are very large. The present invention discloses how these two disadvantages can be eliminated by utilizing articulated crowns of appropriate shapes and proportions.

摘要翻译： 与传统的基于尖端和/或根部消除的修改系统相比，新的传动系齿轮传动系统被称为“差速加冠”，具有优点和缺点。 差速加冠的优点是三重优点：（1）提供基本上恒定的刚度，使其在所有载荷下同样有效; （2）它适合于使第一和第二谐波激励最小化，而常规的修改只能减轻一次谐波激励，只有在一个“设计负载” 和（3），它对制造不准确是不敏感的，因为传统的传动对他们敏感。 然而，差分加冠在其以前公开的形式中具有两个缺点：（1）难以优化; 和（2），除了生产运行非常大以外，它比常规修改更昂贵。 本发明公开了通过使用适当形状和比例的铰接冠来消除这两个缺点。
