Gear Lab - Cylindrical, Bevel, Face Gears

Yup, it's another custom feature for gears. I had previously used Neil Cooke's excellent 'Spur Gear' feature [Link], but I wanted the ability to generate bevel and face gears as well. I only learned about Bob Tipton's great bevel gear FS after I had nearly finished this. I fear that my "Gear Lab" custom feature is largely… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears
Sectors. I have an application where I need to make a sector to mate with a small(er) pinion. My problem is that I can't do the usual trick of making a full circle internal gear and then just trimming it down to a sector of the gear because I would need 1820 teeth in the full circle internal near and there are no tools… -

Re: Gear Lab - Cylindrical, Bevel, Face Gears
Yes, this is because the way Bevel hears are defined here is fundamentally flawed. And it is very clear whoever made it failed to account for basic trigonometry, resulting in a deceiving behavior that fools the user into thinking they got what they want, but in fact the result could be catastrophically malformed, failing… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears
(Writing this partly to organize my own thoughts, and possibly to spur further discussion or comments.) I think many of these issues result from my (admittedly poor) decision to include all types of gears in the feature. The bevel angle input was meant to allow users to create different types of gears, including… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears
Hi there! Loving this tool so far. I think I may have found a bug - it looks like when generating a Bevel gear that inherits from a parent, the Teeth field doesn't actually do anything. After playing around some, I found that the Bevel Angle in the parent gear is what determines the teeth count in the child gear. That may… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears
Hi there. Thanks for this great script! I'm trying to model a simple differential with three bevel gears, which seemed to work well enough. When I tried to punch a 22mm hole through the middle of one of the gears I get weird artifacts where it somehow generates a face around the extrusion and there is still apparently a… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears
Hello there! For better of for worth, this is the best gears script for onshape I have found so far, but it is really frustrating that it generates nice and beautiful bevel gears which are completely unusable because they never allign at correct angle, the only way I managed do get bevel gears at 90deg angle was creating… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears

MATH BUG found ! The behavior of helix angle when working with bevel gears is incorrect. try this: create a bevel gear along with it's pair using the inherit from parent option, but make sure the pair is not 1:1 (bevel angles different than 45 degrees) then section view the teeth meshing zone: everything will be fine now… -
Re: Gear Lab - Cylindrical, Bevel, Face Gears
Thank you for this script. It seems though that the script cannot generate herringbone gears? Whenever I tick the 'herringbone' box it unticks itself instantly, even with the default settings. How can I create a herringbone gear? Also when I click "Go to definition" on "GearLabFeature_Main" I don't get the source code. I…
