Abstract:	摘要： In the high speed rotational gearbox, the tooth surfaces of gears are usually crowned with twist-free tooth flanks to reduce the vibration and noise of the gear systems due to the transmission error and load variation. In this paper, a method for longitudinal crowning tooth flank of work gear surfaces is proposed by setting a crossed angle between the honing cutter and work gear axes as a linear function of work gear's traverse feed and a variable pressure angle (VPA) honing cutter is also used for free twist of the crowned tooth flank in the external honing process. Besides, the transmission and load characteristics of the gear pairs using a crowned pinion with twist-free tooth flanks are need to understand. Therefore, 3-D models of the meshing gear pairs with twisted and twist-free tooth flanks are constructed and analyzed by using KISSsoft software. Three numerical examples are presented to illustrate and verify the merits of the proposed gear honing methodology as well as shed light on the transmission and load characteristics of the gear pairs with twist-free tooth flanks. •A novel method for longitudinal crowning tooth flank of helical gear is proposed.•A linear crossed angle function is constructed for external gear honing process.•A variable pressure angle honing cutter is used for free-twist of the crowned tooth flank.•Transmission and load characteristics of meshing gear pair with twist-free tooth flank have been investigated.•Working conditions of the meshing gear pair have significant advances by applying proposed gear honing method. 出版者： Elsevier Ltd 出版日期： 2016-04-01 出處： Mechanism and machine theory, 2016-04, Vol.98, p.36-47 版權： 2015 Elsevier Ltd 識別號： ISSN: 0094-114X 識別號： EISSN: 1873-3999 識別號： DOI: 10.1016/j.mechmachtheory.2015.11.014
