This paper reveals the latency errors in the manufacturing and assembly of the toroidal drive and integrates these errors in the coordinate systems and the mathematical models of the meshing equations for the conjugate surfaces between the planet wormgear and the sun-worm and between the planet worm-gear and the stationary internal toroidal gear. The paper further develops the tooth profile mod...

Abstract The torsional vibration of marine propulsion shafting has been studied for more than a century. With abundant research achievements and experiences, a systematic approach of vibration calculation has been put forward for ship industrial applications. However, literature review indicates that when processing the gear transmission in the shaft line, the meshing motion has been treated as...

| We present a new method for adaptive surface meshing and triangulation which controls the local level-of-detail of the surface approximation by local spectral estimates. These estimates are determined by a wavelet representation of the surface data. The basic idea is to decompose the initial data set by means of an orthogonal or semi-orthogonal tensor product wavelet transform (WT) and to ana...

The meshing impact on transmission system and internal gear pair its the load sharing dynamic characteristics of are not well understood yet. In this paper, models pairs planetary were successfully constructed, point, time force accurately obtained. Meshing in is obviously affected by eccentricity error, installation other errors. Due to difference error each component, external gears branch le...

Straight line and column envelope type meshing pairs are two important meshing pairs in single screw compressors, while straight line envelope meshing pair is actualized but the other is still fail to meet industrial applications. The column envelope meshing pair of single screw compressors is proposed to improve the operating life of the compressor for poor wear resistance of existing straight...

As the most important working area of gear, teeth play the role of transmitting load and power. Tooth line and tooth profile are the two main characteristics of the tooth surface, which affect the shape of the tooth surface, tooth meshing characteristics and contact characteristics. Taking the elliptical cylinder gear pair in the reversing device of a new type of drum pumping unit as the resear...

The importance of estimating discretization error has been sadly neglected in the computational solid mechanics community. Quite the opposite is true in the computational fluid dynamics community where discretization error estimation is required to publish numerical results in many CFD journals, including the ASME Fluids Engineering Journal. It is suggested that if more solid mechanics types wo...
