摘要:Abstract(#br)The magnitude and location of stress intensity factor (SIF) in mode I (K I ), mode II (K II ), mode III (K III ) relies mainly on the geometry and location of the crack tip, variation in magnitude of load due to multiple pair contact along the active profile and the distribution of the load along the face width...

摘要:Abstract(#br)A non-standard, curved face width gear has been developed in order to obtain a high contact ratio, reduced bending stresses and lower sliding velocities compared to conventional spur gears. The benefits of this gear form make it a suitable candidate for manufacture f...

摘要:... These circular-arc gears, though stronger than involute geras, have the disadvantage of needing larger face width. Axial face width required can be minimized only at the expense of load-carrying capacity. This is not a serious disadvantage with stationary engines. But in the ...

摘要:... This paper mainly deals with deformation distribution across the teeth’s face width in relation to the load width of the teeth when meshing occurs. The solution for teeth deformation of spur gears is provided by the FEM.

摘要:Abstract(#br)High facial width-to-height ratio (fWHR) has been associated with a cluster of behavioural traits in men, including aggression and status-striving. This association between face structure and behaviour may be caused by testosterone. Here we investigated the relations...

摘要:... It is found that the simulated flow patterns are totally different from those calculated for spur gears and that both tooth face width and helix angle are influential. The windage losses derived from Dawson's and Townsend's formulae are critically assessed using computational...

摘要:... 341–355]) asserts that every bridgeless cubic graph can be embedded on a surface of its own genus in such a way that the face boundaries are cycles of the graph. Sporadic counterexamples to this conjecture have been known since the late 1970s. In this paper we consider ...

摘要:Abstract(#br)Tutte has shown that every 4-connected planar graph contains a Hamilton cycle. Grünbaum and Nash-Williams independently conjectured that the same is true for toroidal graphs. In this paper, we prove that every 4-connected toroidal graph contains a Hamilton path.
