Abstract

For increasing the load carrying capacity of geared power transmissions several tooth designs alternative to the standard involute have been proposed. The use of non-involute teeth has a number of disadvantages and for this reason asymmetric involute-type teeth have been studied as a promising alternative. In this article the idea of one-sided involute asymmetric spur gear teeth is introduced to increase load carrying capacity and combine the good meshing properties of the driving involute and the increased strength of non-involute curves. These novel teeth are intended for constant direction of rotation, although they can be used in a limited way for reverse rotation. Both profiles are fully generated by a hob, the design of which is also investigated. The increase in load carrying capacity can reach up to 28{%} compared to the standard 207° involute teeth.
