The paper deals with the geometry and kinematics of right-angle bevel gears that feature low tooth count.
Gears that have 1 2 teeth and fewer are referred to as the low-tooth-count-gears (or just gears, for
simplicity). It should be stressed from the very beginning that gears are not covered by either AGMA, or
by any other national/international standards on gearing. This is mostly because of the kinematics and
geometry of gears is not profoundly investigated yet.
When operating, right-angle bevel gears generate vibration and produce an excessive noise. Dynamic
loading of the gear teeth can result in the tooth failure. These problems become more severe in bevel
gearings with low tooth count.
