AB  - This study covers the method of representation of any pitch curve (centrode shape) in noncircular
gears by deriving a general mathematical equation contains a number of parameters such that this equation can
give any centrode shape depending on the selected values of these parameters. In addition, a tooth of double
circular arc profile has been generated by hob method and distributed over the pitch curve of noncircular gear
by using the required equations of tooth profile generation. These equations are applicable for any module and
pressure angle and give the required double circular arc tooth form. Equations of pitch curve representation
and tooth profile generation have been programmed using SOLIDWORK program. Therefore, when the
parameters of pitch curve and tooth profile have been changed, the program will generate the required shape
of noncircular gear centrode and the tooth form which can be distributed over the pitch curve. The resulting
noncircular gear can be manufactured by CNC machine by coupling SOLIDWORK program file of the generated
noncircular gear with this machine. Also, static and dynamic analysis of these gears can be achieved using
SOLIDWORK package or using any other program accept SOLIDWORK files such as ANSYS package.
