Deep Contact Endurance Limit of Surface-Hardened Gears
Механика машин, механизмов и материалов, 2023 The reliability and durability of gears in most cases depend on the contact endurance of the material of the parts. Analysis of the stress state of surface-hardened gears has shown that under contact loading, the source of primary damage can be located ...
