A calculation method of sliding friction coefficient on tooth surface for helical gear pair based on loaded tooth contact analysis and elastohydrodynamic lubrication theory

Abstract: The sliding friction coefficient on tooth surface is related to power loss, carry capacity and transmission performance of gear. Reasonable transmission analysis of gear pair is the premise of accurate calculation of sliding friction coefficient on tooth surface. However, for helical gear pair, the line contact without considering machining error/installation error/modification of gear is usually adopted to replace the major axis of ellipse caused by contact load. Therefore, in this paper, contact path on toot… Show more

“…They combined tooth surface friction with power loss and tooth surface elastohydrodynamic lubrication [9] and proposed a calculation method of sliding friction loss of involute helical gear pair under load [10], considering assembly error, machining error, deformation, and other factors. On this basis, the friction power loss and transmission efficiency of the gear transmission system under different working conditions and design parameters are analysed [11] to [12], and the relevant data are obtained by building an experimental platform, which finally verifies the rationality of the proposed method [13] to [14]. Petry-Johnson et al [15] obtained the transmission efficiency of the system under the condition of high speed and variable torque by building a gear transmission test and analysed the changing trend of the meshing efficiency of the gear transmission system and the total efficiency of the gearbox under the condition of different speed and load torque.…”

“…It is also clear that including realistic run-in surface topography shows a very marginal effect upon boundary friction. Although in some other studies boundary regime of lubrication has been found to play a more significant role for some gearing systems, including for hypoid gears with different roughness patterns [60,61]. The boundary friction model used in the current study is based on the work of Greenwood and Tripp [48] with reported measurements by Paouris et al [35,49].…”

“…According to the research of Pu et al (2016), Wang and Ken (2021), the friction coefficient fluctuates in the range of 0.01$0.15. According to the entrainment speed, and the sliding friction coefficient of tooth surface under sufficient lubrication is 0.05.…”
