The Propulsion Mechanism with High-Order Elliptic Profile Shaft Connection

Abstract:

Dealing with the existing propulsion mechanism, the paper analyzes the deficiency of the flat key and the spline, studies the specialities of high-order elliptic profile. On the basis of chain propulsion mechanism, we get a high-order elliptic profile shaft connection. (a keyless joint) through changing the fit of the inner hole of sprocket gear and the outer circle of intermediate shaft, then introduce the propulsion mechanism with high-order elliptic profile shaft connection. At last, applying Solidworks2011 software, we create the three-dimensional modeling of the propulsion mechanism, thus laid a solid foundation for the further study. This new propulsion mechanism enjoys the superiorities like self-centralizing, easy disassembly, low stress concentration, with a simple fit cross-section, transmitting big torque, suitable for the heavy loads of rock drilling.
