The
design of bevel gear for use in the development of revolving rostrum is
presented. The pinion gear is designed to rotate at 1400 rpm for the output
gear of 23 rpm. A suitable gearmotor was selected for the design based on the
bevel gear design analysis. The motion is transmitted to the rostrum via a
shaft keyed to it with a gib-head key and assembled on the rostrum with a
spline connector. The analysis of the bevel mesh shows that maximum deformation
of about 26.552 mm occurs in the pinion due to the loading the pinion tooth.
The deformation of the tooth is observed to affect considerable the performance
of the system. The transmission efficiency of the mechanism was obtained as 86% though effective for the
operation of the system butcould be
improved by a more careful material selection for the bevel gear mesh.
