Abstract
The scuffing load capacity of gear is closely related to the meshing temperature rise of tooth surface. The key to predict the temperature rise is to establish an accurate meshing temperature rise model. In the paper, a tribo-dynamic model of helical gear is established through coupling of tooth surface lubrication parameters, and the influence of temperature rise on ambient temperature during meshing process is considered. Then, the effects of oil supply temperature, input speed and torque on tooth surface temperature rise, film thickness, friction excitation and gear dynamic characteristics are discussed. The results show that the temperature rise of the gear is higher during the engaging-in and engaging-out regions. Meanwhile, there is local high temperature at the end of the contact line due to the end effect. The vibration of gear along the off-line-of-action direction is mainly determined by friction excitation. With the increase of oil supply temperature, input speed and torque, the risk of scuffing failure increases and the influence of oil supply temperature and input load is more significant. The conclusions of this paper may provide some valuable suggestions for the anti-gluing failure design of gear in engineering.
期刊介绍:
Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development.
Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on:
Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives.
State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces.
Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles.
Gas lubrication.
Extreme-conditions lubrication.
Green-lubrication technology and lubricants.
Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions.
Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural.
Modelling hydrodynamic and thin film lubrication.
All lubrication related aspects of nanotribology.
Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption.
Bio-lubrication, bio-lubricants and lubricated biological systems.
Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
