The Propulsion Mechanism with Enveloped Isometric Trilateral Profile Shaft Connection

Abstract:

This paper deals with the existing propulsion mechanism, analyzes the disadvantages of the flat key and the spline, studies the features of the generated isometric trilateral profile shaft connection. 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 a generated isometric trilateral profile shaft connection(a keyless joint), then introduce the propulsion mechanism with generated isometric trilateral profile shaft connection. At last, 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.
