Abstract
The invention relates to a gear pair consisting of a crown gear (1) and of a pinion gear (2) provided in the form of a spur gear with an axis crossing angle of 90°. According to the invention, the teeth (3) of the pinion gear (2), in order to reduce an undercut of the teeth (5) of the crown gear (1), have a pressure angle, which increases from the outside inward in a radial direction with regard to the crown gear (1), or in the event of a constant pressure angle, have a profile offset, which decreases from the outside inward in a radial direction with regard to the crown gear (1).
Claims19
A gear pair comprising a crown gear (1) and pinion (2) as a straight-toothed spur gear, wherein the axes intersect at an angle of 90°,
- wherein
- teeth (3) of the pinion (2), in order to reduce an undercut of teeth (5) of the crown gear (1), are provided with a pressure angle that increases from outside to inside in a radial direction relative to the crown gear (1).
A gear pair comprising:
- a crown gear and a pinion gear each having a central axis, the axes intersecting at a 90 degree angle;
- the crown gear comprising a first toothing;
- and
- the pinion being a straight-toothed spur gear and comprising a second toothing, the second toothing comprising a variable profile displacement from outside to inside in a radial direction relative to the crown gear and a pressure angle that increases from outside to inside in the radial direction relative to the crown gear to reduce an undercut of the first toothing;
- wherein the pinion revolving on the crown gear is guided axially.
