The Profile Shaft Connection of Inner Gear with Swing Movable Tooth in Propulsion Mechanism

Abstract:

This paper deals with the existing propulsion mechanism, analyzes the disadvantages of the flat key and the spline, studies the features of the profile curve of the inner gear with swing movable tooth. In an existing chain propulsion mechanism, we change the fit of the inner hole of sprocket gear and the outer circle of intermediate shaft to get the profile shaft connection of inner gear with swing movable tooth (a keyless joint), then introduce the propulsion mechanism with it. At last, applying Solidworks2010 software, we create the three-dimensional modeling of the propulsion mechanism, which would lay a solid foundation for the further study. This new propulsion mechanism has such advantages as self-centralizing, easy disassembly, low stress concentration, with a simple fit cross-section, transmitting big torque, suitable for the heavy loads of rock drilling.
