Design and analysis of a multi spindle drill gearbox Torque divider

Abstract

Gearboxes play an important role in many applications. One of the important applications is in multi spindle drilling machine. So, it is necessary to study and analyze the gearbox. In general, gear analysis includes calculations of the tooth stresses, failures due to bending, wear or scoring by considering both the beam strength and fatigue strength. In the multi spindle drilling machine, smooth functioning of the gearbox is of utmost importance. This paper gives the design and analysis of the gearbox of a special purpose machine for drilling application. In this paper, bending stress analysis will be performed on different size spur gears to investigate the weakest portion against bending. Then bending stresses calculated using ANSYS 15 workbench, are compared to the results obtained from existing or theoretical methods.
