zigmasas Posted January 23, 2014 Share Posted January 23, 2014 Hi, i need to draw 2D gears with tooth i know just: Module m=10mm Number of Teeth= Za=13 Zb=30 To drow i need to know diameters and wheelbase size so i calculated according formules: Holding on the drive angle=26,6degree d=mz d1=130mm d2=300 Tooth crown height =10mm Tooth height of its core=12,5mm tooth height=22,5mm Gear tops circle=150mm and 320mm Knuckle its core circle=105mm and 275mm Can some draw gears? please gears.dwg Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 23, 2014 Share Posted January 23, 2014 I know of at least one lisp routine that will draw a 2D spur gear for you. All it requires is three inputs: Pitch, Number of teeth and Pressure angle. Would that work for you? Quote Link to comment Share on other sites More sharing options...
zigmasas Posted January 23, 2014 Author Share Posted January 23, 2014 yea it would be great, but what it means pitch? i not not very good in English. Number of teeth one gear 13 second 30. In this drawing i just need to show 2 gears with teeth and how teeth engage (cling) each other just simple drawing 2d Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 23, 2014 Share Posted January 23, 2014 From the Gears and Stuff Home Page: Pitch: The distance between similar, equally-spaced tooth surfaces, in a given direction and along a given curve or line. You can find Tony Hotchkiss's SPURGEAR.LSP and SPURGEAR.DCL files by following this link to the Cadalyst magazine website. http://cadtips.cadalyst.com/standard-blocks/spur-gear-updated Quote Link to comment Share on other sites More sharing options...

ReMark Posted January 23, 2014 Share Posted January 23, 2014 To run the second lisp routine load the program then type 2Dgear at the command line to start it. My copy works using AutoCAD 2014. Quote Link to comment Share on other sites More sharing options...
