ABSTRACT To improve the conveying efficiency and working stability of a screw conveyor, the feeding methods, running conditions and flow characteristics of materials were studied by theoretical ...

Abstract: As the helical gear is widely used as transmission part in the planetary gear train system, a six-degree-of-freedom bending-torsion-axis coupling dynamic model is established for the helical ...

In this paper, a dispersive coupling structure for helical resonator filters is proposed for generating transmission zeros (TZs) in an in-line coupling topology. The coupling structure is composed of ...
