    摘要： It is an object of the present invention to approximate of life of each resin double helical gear of a gearing resin double helical gear pair to each other by effectively increasing the strength of the tooth of the resin double helical gear with the higher rotational speed; and to lengthen life of the gearing resin double helical gear pair by effectively increasing the strength of the tooth of the resin double helical gear that comes to the end of its life earlier due to stress concentration out of the gearing resin double helical gear pair. A resin double helical gear pair includes a first resin double helical gear and a second resin double helical gear with the larger diameter gearing into the first double helical gear. The first double helical gear is formed so that at least an addendum modification coefficient of a peak of a chevron tooth is larger than addendum modification coefficients of other sections. The second double helical gear is formed so that a sum of the addendum modification coefficient of the first double helical gear and an addendum modification coefficient of the second double helical gear in a gearing position of the first double helical gear and the second double, helical gear is a constant value along a tooth width direction.

    摘要： The invention relates to the gearing of a gearwheel having a plurality of teeth. The gearwheel has a useful area and a base area of the particular tooth flank form. Viewed in normal section, the tooth base area extends from a base circle up to a useful circle. The tooth flanks of adjacent teeth in normal section are each implemented as symmetrical to one another, the axis of symmetry intersecting the base circle in the base point. According to the invention, the tooth flanks are implemented in the tooth base area as a tangent function from a relevant diameter. The tangent function merges at the relevant diameter in a constant tangent into the tooth flank form of the useful area. The tangent function merges in the tooth base area in a constant tangent into an orbit, which is tangentially applied in the base point to the base circle. Significant increases of the tooth base strength may thus be achieved.

    摘要： Helical or spur gear drive comprising a driven gear and driving gear wherein the driving gear has double crowned teeth defined as (i) an envelope to a family of surfaces generated by a skew or straight rack-cutter having a parabolic tooth profile in normal section and then (ii) as an envelope to a family of tool surfaces that are generated while the tool performs a plunging motion with respect to the driving gear in the direction of the shortest distance between the axes of rotation of the tool and the driving gear and tool plunging motion is varied by a parabolic function, whose variable is displacement of the tool in a direction parallel to the rotational axis of the driving gear. The driven gear has a tooth surface defined as the envelope to a family of surfaces generated by a rack-cutter which surface is parabolic cylinder or a plane. The generated pinion/gear tooth surfaces are in theoretical point contact at every instant and they produce a preselected parabolic function of transmission errors in the process of meshing. The pinion/gear exhibit reduced vibration and noise, reduced shift of bearing contact caused by misalignment, and reduced contact stresses due to convex-concave contact of tooth surfaces.
