cdobbins Posted January 6, 2006 Share Posted January 6, 2006 I must be making this too hard! How to draw a simple gear with 9 teeth, spaces same size as the teeth, angle between sides of tooth 30 degrees. (I know there is a lisp for this, but I want to be able to draw it manually). Thanks!

Lazer Posted January 6, 2006 Share Posted January 6, 2006 I would use the Array command. just draw 1 tooth and array it. Quote Link to comment Share on other sites More sharing options...
cdobbins Posted January 6, 2006 Author Share Posted January 6, 2006 With this information only, how do I know how wide to make the tooth? (Besides trial and error). I'll try to post a little drawing of the exercise. But picture a tooth with the only dimension extended lines at the widest part of the tooth "30 degree angle" and the following: TOOTH THICKNESS EQUAL TO SPACE 9 TEETH & 9 SPACES CENTERLINE DIAMETER 27 OUTSIDE DIAMETER 30 INSIDE DIAMETER 24 CDobbins Quote Link to comment Share on other sites More sharing options...
Big Mike Posted January 6, 2006 Share Posted January 6, 2006 Or you could use the 'divide' command to get equal spaces around your circle. Quote Link to comment Share on other sites More sharing options...
cycles Posted October 14, 2009 Share Posted October 14, 2009 i need to draw gear , 20 teeth, diametral pitch5, 20 degrees pressure angle , face width 2.500 shaft diameter 1.125 keyway for a .25 square key.. need a detail drawing?? Quote Link to comment Share on other sites More sharing options...
ReMark Posted October 14, 2009 Share Posted October 14, 2009 I doubt anyone here is going to make you a detailed drawing of the gear you're looking for. There have been other threads posted regarding drawing gears in the past so I suggest you use the Search feature above to find some of them. Oh, and do you have a good technical or engineering drawing book at hand? If not, you might want to consider picking one up. For that search use the words draw gear. I know it works because I just tried it myself. If you still have questions post them. Quote Link to comment Share on other sites More sharing options...

ReMark Posted October 15, 2009 Share Posted October 15, 2009 In the spirit of brotherly love I offer the following. Need help drawing a standard involute gear profile in 2D then head on over to: http://www.xanadu.cz/en/download.asp Page way down until you come to CAD Utilities. Under this heading look for then download TrueGear.lsp v2.10.2005 written by Eugeny Kalney. It's approximately 39KB in size. Quote Link to comment Share on other sites More sharing options...
stratt28 Posted October 15, 2009 Share Posted October 15, 2009 Tommy78!!!! OMG.... I haven't laughed that hard this early in the morning in ages! Awesome....I luv it! Quote Link to comment Share on other sites More sharing options...
Glen Smith Posted October 15, 2009 Share Posted October 15, 2009 You think I was too harsh? No I do not. If you don't have the sense to find out what a forum is like by lurking for a while before posting, don't be surprised when the locals tell you the rules in no uncertain terms. I have found the people here to be extremely helpful, surprisingly so. But the question asked was not "what is the process for drawing a gear?" It (sounded to me like) "who will be drawing this gear for me?" Glen PS. Tommy, that gear has 18 teeth - 2 short of what the second request was for!
