Abstract
In a bevel gear pair, a first gear (G1) and a second gear (G2) are applied with tooth top modification, and a ratio of a distance (L1b) from a pitch circle (P1) to a starting position (R1) of the tooth top modification to a distance (L1a) from the pitch circle (P1) to a tooth top (T1) in the first gear (G1) is larger than a ratio of a distance (L2b) from a pitch circle (P2) to a starting position (R2) of the tooth top modification to a distance (L2a) from a pitch circle (P2) to a tooth top (T2) in the second gear (G2). Thus, the bevel gear pair that can achieve smooth meshing is provided.
Claims7
A bevel gear pair comprising a first gear and a second gear that mesh with each other, the second gear having a larger number of teeth than the first gear, wherein
- each of the first gear and the second gear is applied with tooth top modification, and
- a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from the pitch circle to a tooth top in the first gear is larger than a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from a pitch circle to a tooth top in the second gear.
