Straight bevel gear
teeth actually have the same problem as straight spur gear teeth as each tooth engages, it impacts the corresponding tooth all at once.
According to a graph supplied by Wilcox , a straight bevel gear tooth ratio of [N.sub.4]/[N.sub.3] = 81/80 = 1.0125 can be used with a maximum shaft angle of 178 degrees.
Coupling the mathematical concept of nutation with straight bevel gears, a class of gears has been developed that provides speed-reduction and torque-multiplication factors in a high-shaft-angle bevel gear configuration.
MAKING A STRAIGHT BEVEL GEAR
USING CAD, CAE AND CAM TECHNIQUES
From the review of the past work it is evident that as of now no research has been reported on development of ECH for finishing the straight bevel gears. The present work bridges this gap through development of the ECH process for improving surface finish and surface integrity of the straight bevel gears and experimental investigations on the process performance.
The workpiece, cathode and honing gears were straight bevel gears having module as 4.83.
This paper reported about the experimental investigations on effect of electrolyte parameters on the enhancement of surface finish and surface characteristics of the straight bevel gears using an innovatively developed ECH setup.
