gear profile

[idacing]

Is there any tools for make gearprofile (spur gear) in proe. Thanks

better than that, you can download a gear from this site!


But the 'equation curve' that produces an involute profile is:


RB=(PITCH/2)*COS(P_A)
X=RB*(COS(T*180/PI)+T*SIN(T*180/PI))
Y=RB*(SIN(T*180/PI)-T*COS(T*180/PI))
Z=0


Where rb= base circle radius


p_a=pressure angle ( needs to be added as a real number parameter before you create the curve)


pitch=pitch circle diameter ( needs to be added as a real number parameter before you create the curve)
