Comparative Analysis of Stress–Strain Condition of Cylindrical Gears Arc Teeth and Spurs
The paper deals with a comparative analysis of the stress–strain condition (SSC) of cylindrical gear arc teeth and spurs at different angles of shafts misalignment. The calculation of the teeth SSC was performed using the finite element method under their loading with distributed load on the top edge of the tooth. The laws of load distribution on the top edge of the tooth were established as a result of solving the problems of loading arc and spur gears for different angles of misalignment. The results of the research showed that compared to spur gears, arc tooth gears are exposed to 27% (6′ misalignment) less overall displacements and have 18% (6′ misalignment) greater bending strength and durability in actual service conditions. It allows making a conclusion about the expediency of application of arc teeth cylindrical gears in high-loaded transmissions (for example, in the high-loaded transmissions of electric locomotives EP-100 and EP-200).
