Abstract
Finishing technology has become an important process in the manufacture of high-performance gears due to its positive effect on surface roughness and residual stresses. However, the important effect of finishing technology on the micro-profile of gears is often overlooked. To systematically investigate the imporve mechanisms of finishing processes on case-hardened gears, this research examines the influences of vibration honing (VH) and stream barrel (SB) finishing processings on the surface integrity characteristics and contact fatigue damage evolution of carburized 16Cr3NiWMoVNbE gears. The results indicate that the surface roughness slight decrease after the SB and VH finishing. The compressive residual stress of three sets gears is more than −850 MPa. Furthermore, micro-profile of the tooth tip is modified by increasing the transition arc between the tooth flank and the chamfer face. The application of surface finishing effectively mitigates contact fatigue damage. This is primarily achieved through modification of the tooth tip micro-profile to mitigate contact interference between the tip and root regions.
期刊介绍:
Engineering Failure Analysis publishes research papers describing the analysis of engineering failures and related studies.
Papers relating to the structure, properties and behaviour of engineering materials are encouraged, particularly those which also involve the detailed application of materials parameters to problems in engineering structures, components and design. In addition to the area of materials engineering, the interacting fields of mechanical, manufacturing, aeronautical, civil, chemical, corrosion and design engineering are considered relevant. Activity should be directed at analysing engineering failures and carrying out research to help reduce the incidences of failures and to extend the operating horizons of engineering materials.
Emphasis is placed on the mechanical properties of materials and their behaviour when influenced by structure, process and environment. Metallic, polymeric, ceramic and natural materials are all included and the application of these materials to real engineering situations should be emphasised. The use of a case-study based approach is also encouraged.
Engineering Failure Analysis provides essential reference material and critical feedback into the design process thereby contributing to the prevention of engineering failures in the future. All submissions will be subject to peer review from leading experts in the field.
