This paper presents cogging torque reduction methods for an axial-gap magnetic gear utilizing combination of the number of poles with the stationary pole pieces and modifying the pole piece shape. The present study is aimed to develop a magnetic gear, which has a large transmission torque over 360Nm by using the three-dimensional finite element method. The maximum transmission torque of 300Nm w...

In this paper, a transient temperature calculation model for simulating grinding face gear with worm is proposed. Firstly, according to the principle of differential geometry, equations determining contact length and width instantaneous area between wheel are deduced. Based on method single abrasive particle cutting force heat, mathematical heat established, theoretical formula maximum teeth ob...

In this paper the effects of gear contact force shuttling (axial movement of the resultant contact force point of application) are discussed as an important excitation which is seldom included in gear modelling. The main phenomena which generate this excitation are discussed. Two formulations are proposed for multibody models, where computational efficiency must be kept high in order to perform...

Efficient transmissions systems are key to producing competitive motor vehicles that have a smaller environmental impact. Gears are the main components in vehicle transmissions and although they are already highly efficient, there is still room for improvement. In this study, the focus falls on the lubricant used to create separating films between gears and to dissipate heat. When driving, the ...
