Design and Analysis of Yoke of Mill Rope Coupling

Abstract

A conventional tail bar coupling can cause serious complications to the mill drive components. Misalignment between the mill and gearing, shaft cracks, thrust load, sluggish floating of the top roller, rounding of the shaft square ends, damage to the crown pinion, and damage to the last motion gear bearing due to excessive thrust are common problems associated with the tail bar coupling. The mill rope coupling is an alternative to the tail bar coupling that eliminates damage caused by misalignment between mill and gearing and reduces other problems caused by the tail bar coupling. The primary objective of the study is to Design and carry analysis of Yoke for Mill Rope Coupling considering that the cost & weight reduction is extremely important & the availability of the material, Machinability & strength. Data of input power, output speed, Torque, Forces are calculated and analyzed. Strain gauges will be used to measure torque. Study produced the following conclusions: design yoke after changing material & thickness of plate withstand after applying torque & forces.
