Signature
def make_herringbone_ring_gear_rsolid(n_teeth: 'int', module: 'float', pressure_angle: 'float' = 20.0, helix_angle: 'float' = 30.0, gear_height: 'float' = 10.0, rim_thickness: 'float' = 3.0, backlash: 'float' = 0.0, *, addendum_factor: 'float' = 1.0, clearance_factor: 'float' = 0.25) -> 'Solid'
Description
Create an internal herringbone ring gear.
Create an internal herringbone ring gear.
The outer rim is extruded directly. The internal tooth void is built as two small-step ruled loft halves sharing the center herringbone section, then subtracted from the rim. Ruled sections avoid smooth loft bulging in STEP exports while preserving stable section correspondence.
Parameters ---------- n_teeth : int Number of internal teeth (>= 3). module : float Gear module in mm. pressure_angle : float, default 20 Pressure angle in degrees. helix_angle : float, default 30 Helix angle of each half in degrees. gear_height : float, default 10.0 Total ring gear thickness along Z in mm. rim_thickness : float, default 3.0 Thickness of the rim beyond the tooth roots in mm. backlash : float, default 0.0 Circumferential tooth-space clearance at the pitch circle in mm. addendum_factor : float, default 1.0 Internal tooth addendum as a multiple of module. clearance_factor : float, default 0.25 Internal tooth root clearance beyond the addendum, as a multiple of module.
Parameters
| Name | Type | Required | Default | Source description |

pressure_angle | 'float' | no | 20.0 | Not explicitly described in the source docstring. |
helix_angle | 'float' | no | 30.0 | Not explicitly described in the source docstring. |
gear_height | 'float' | no | 10.0 | Not explicitly described in the source docstring. |
rim_thickness | 'float' | no | 3.0 | Not explicitly described in the source docstring. |
backlash | 'float' | no | 0.0 | Not explicitly described in the source docstring. |

Returns
Type: 'Solid'
The source docstring does not declare additional return semantics.
Errors
The source docstring does not declare a narrower exception contract. Invalid types, values, ownership, paths, or backend state may still raise the corresponding public error.
Behavior and constraints
- The contract below is generated from the current public runtime signature. Check domain notes for ownership and workflow constraints.
