... the gear system to avoid jamming and gear tooth scuffing/seizing problems caused by zero backlash and thermal expansion. In order to test that hypothesis, a mathematical model for the single-roller enveloping hourglass worm gear is developed, which includes a gear engagement equation and a tooth profile...

... screw compressor wear curved flank tooth profile The single screw compressor was first developed by Bernard Zimmern in the early 1960s [ 1 ]. Initial sales were of machines compressing air, but refrigeration models followed [ 2 ]. The primary components of a typical single screw compressor...

... of differential geometry and gear meshing, this paper presents generic models of meshing characteristics for ADEHW gears, including both the contact curve and the tooth profile. We present different meshing functions and their derivatives with respect to each drive type and their associated roller shapes. We also...

...Jian Wang; Shanming Luo; Yue Wu This paper proposes a method of the preliminary geometric design for gear tooth profiles based on given sliding coefficients. A design procedure is developed and a simplified derivation of the mathematical model of tooth profiles is presented. The characteristics...

...Ligang Yao; Bing Gu; Shujuan Haung; Guowu Wei; Jian S. Dai The purpose of this paper is to propose a pair of external and internal spiral bevel gears with double circular-arc in the nutation drive. Based on the movement of nutation, this paper develops equations of the tooth profiles for the gear...

...Jiqiang Xia; Yuanyuan Liu; Chunming Geng; Jiangbin Song Noncircular bevel gear can achieve variable transmission between intersecting axes. Based on polar coordinates, a design method for noncircular bevel gears is presented. The geometric characteristic of tooth profiles of the gears can...

...Ligang Yao; Jian S. Dai; Guowu Wei; Huamin Li This paper investigates the geometric properties of the toroidal drive, reveals the meshing characteristics, and develops analytical models of both axial section and normal section of the toroidal tooth profile. Based on coordinate transformation...
