FCGear: Ingranaggio ad evolvente esterno |
Descrizione
Ingranaggi ad evolventi interni da sinistra a destra: ingranaggi cilindrici, ingranaggi elicoidali, ingranaggi elicoidali doppi
Utilizzo
- Passare a
FCGear.
- Esistono diversi modi per richiamare il comando:
- Premere il pulsante
Internal Involute Gear nella barra degli strumenti.
- Selezionare l'opzione Gear →
Internal Involute Gear dal menu.
- Premere il pulsante
- Modificare il parametro dell'ingranaggio alle condizioni richieste (vedere Proprietà).
Proprietà
Un oggetto FCGear InternalInvoluteGear deriva da un oggetto Part Feature ed eredita tutte le sue proprietà. Ha inoltre le seguenti proprietà aggiuntive:
Dati
accuracy
- Datinumpoints (
Integer
): Il valore predefinito è6
. Modifica del profilo dell'evolvente. La modifica del valore può portare a risultati imprevisti.
base
- Datiheight (
Length
): Default is5 mm
. Value of the gear width. - Datimodule (
Length
): Default is1 mm
. Module is the ratio of the reference diameter of the gear divided by the number of teeth (see Notes). - Datiteeth (
Integer
): Default is15
. Number of teeth (see Notes). - Datithickness (
Length
): Default is5 mm
. Thickness of the uncut outer part of the gear.
computed
- Datiangular_backlash (
Angle
): (read-only) - Datida (
Length
): (read-only) Inside diameter, measured at the addendum (the tip of the teeth). - Datidf (
Length
): (read-only) Root diameter, measured at the foot of the teeth. - Datidw (
Length
): (read-only) Working pitch diameter. - Datioutside_diameter (
Length
): (read-only) Outside diameter. - Datitransverse_pitch (
Length
): (read-only) Pitch in the plane of rotation.
fillets
- Datihead_fillet (
Float
): Default is0 mm
. - Datiroot_fillet (
Float
): Default is0 mm
.
helical
- Datibeta (
Angle
): Default is0 °
. With the helix angle β a helical gear is created – positive value → rotation direction right, negative value → rotation direction left (see Notes). - Datidouble_helix (
Bool
): Default isfalse
,true
creates a double helix gear (see Notes). - Datiproperties_from_tool (
Bool
): Default isfalse
. Iftrue
and Datibeta is not zero, gear parameters are recomputed internally for the rotated gear.
involute
- Datipressure_angle (
Angle
): Default is20 °
(see Notes). - Datishift (
Float
): Default is0
. Generates a positive and negative profile shift (see Notes).
precision
- Datisimple (
Bool
): Default isfalse
,true
generates a simplified display (without teeth and only a cylinder in pitch diameter).
tolerance
- Datibacklash (
Length
): Default is0 mm
. Backlash, also called lash or play, is the distance between the teeth at a gear pair. - Daticlearance (
Float
): Default is0.25
(see Notes). - Datihead (
Float
): Default is-0.4 mm
. This value is used to change the tooth height. - Datireversed_backlash (
Bool
):true
backlash decrease orfalse
(default) backlash increase (see Notes).
version
- Dativersion (
String
):
