Abstract
Abstract A bevel gear drive provided with circle-arc teeth in which the face of the contacting driven gear tooth is located at such a distance from the pinion axis along the center-to-center line of a reference spur gear drive which exceeds the radius of the pinion pitch circle by up to 0.5 ms at xi 1+ xi 2 > 0 and up to 0.1 ms at xi 1 + xi 2 0 The relation of addenda of the contacting teeth in case of an equal-shift correction is h1/h2 -13 to -76 while in case of an unequal-shift correction it is h1/h2 1.30 - 6.0.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A bevel gear drive provided with circle-arc teeth comprising a pinion having an axis and a mating gear the improvement being that the face of the contacting tooth of the mating gear is located at such a distance from the pinion axis along the centerto-center line of a reference spur gear drive which exceeds the radius of the pinion pitch circle by up to 0.5 ms at xi 1 + xi 2 > 0 and up to 0.1 ms at xi 1 + xi 2 0 where ms face module; xi 1 and xi 2 shift coefficients of cutter tool; in the case of an equal-shift correction the relation of addenda of the contacting teeth is h1/h2 - 13 to -76 while in the case of an unequal-shift correction h1/h2 1.30 - 6.0 where h1 pinion addendum and h2 gear addendum.
Claim 2
Dependent Claim
