Abstract

High transverse contact ratio (HCR) involute gears present advantages in relation to standard involute gears, such as improved load capacity, smoother torque transfer, reduced meshing noise and extended gear life. As internal gearing is important for the design of gearboxes and crane rotation mechanisms, the load capacity of internal HCR gearing has been analyzed and the problem of load distribution in internal HCR gearing researched. Based on the results of this analysis, tooth root and Hertzian stresses along the path of contact have been calculated. The maximum stresses along the path of contact were used as a reference value and compared to results of tooth stress calculations according to the DIN 3990 standard. Research has shown that the calculation according to DIN 3990 provides rather inaccurate results for internal HCR gearing, although with higher safety factors.
