From my observation, the tooth thickness is less than half of the circular Sun, 13 Dec 2020 05:02:08 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24636#M52582 vsimon 2020-12-13T05:02:08Z Re: Spur gear design https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24637#M52583 <HTML><HEAD></HEAD><BODY><P>This error may occur due to improper center distance values.How to calculate the exact center distance values?</P></BODY></HTML> Sun, 21 Feb 2016 14:48:47 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24637#M52583 vsimon 2016-02-21T14:48:47Z Re: Spur gear design https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24638#M52584 <HTML><HEAD></HEAD><BODY><P>There may also be a ratio issue. </P><P>Creo truncates or rounds ratio values to a low number of places where the total number of digits are counted. </P><P>It is like 6 digits only.</P><P>Another issue you might be dealing with is graphic artifacts...</P></BODY></HTML> Sun, 21 Feb 2016 19:10:37 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24638#M52584 TomD.inPDX 2016-02-21T19:10:37Z Re: Spur gear design https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24639#M52585 <HTML><HEAD></HEAD><BODY><P>This is a similar problem where the ratios easily go past single precision values.</P><P></P><P><A href="https://www.ptcusercommunity.com/docs/DOC-3611">Radial Ball Bearing: Checking your mechanism links</A></P><P></P><P><IFRAME frameborder="0" width="425" height="350" src="https://www.youtube.com/embed/M_QWgjaTHkI" allowfullscreen=""></IFRAME></P><P></P><P></P><P></P><P>and for the fun of it...</P><P></P><P><IFRAME frameborder="0" width="425" height="350" src="https://www.youtube.com/embed/J7rumrR5RWw" allowfullscreen=""></IFRAME></P></BODY></HTML> Mon, 22 Feb 2016 01:05:57 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/Spur-gear-design/m-p/24639#M52585 TomD.inPDX 2016-02-22T01:05:57Z
