Abstract

In this study, the strength design was performed considering dedendum modification to avoid a premature tooth contact and an unfavorable transmission error for the roller-rack and pinion (RRP) system. The load distribution of the single tooth contact (STC) and double tooth contact (DTC) regions was presented by introducing the gear precision and load sharing factor. Notably, the dedendum modification produced lower contact and root bending stresses in the load transition from DTC to STC or from STC to DTC. Finally, the finite element analysis with the application of over pin indentation load on the highest point of STC was performed to verify the theoretical results, and the result showed a good agreement with the theoretical results within a 3% deviation.

Keywords:

RRP(roller-rack and pinion) system, Gear precision, Dedendum modification, Load sharing factor, Over pin indentation
