Base Helix Angle
From Gear data
ß = helix angle (15º)
an = pressure angle normal (20º)
Base Helix Angle: bb
= asin(sin(ß)*cos(an)
= asin(sin(15)*cos(20)
= asin(0.258819*0.9396926)
= asin(0.2432103)
= 0.245674211radians (14.07609542º)

Base Helix Angle
|
|
|
|
||
| The angle, at the base cylinder of an involute gear, that the tooth makes with the gear axis. | ||
| Whereas: From Gear data ß = helix angle (15º) an = pressure angle normal (20º) |
||
| Formula:
Base Helix Angle: bb = asin(sin(ß)*cos(an) = asin(sin(15)*cos(20) = asin(0.258819*0.9396926) = asin(0.2432103) = 0.245674211radians (14.07609542º) |
