Non-Circular Gears / Graphics

[MBrez]

Hello Everyone,

Not sure if it?s my computer or a programming issue plus I?ve notice some capabilities are not available from Gearotic 1.  Please use the attached file to verify some issues I?m having and are as follows.

1. Sequence of Operation ? DRIVE GEAR A drives GEAR B/SHAFT 2, GEAR C is attached to SHAFT 2, GEAR C drives GEAR D.
2. When simulated GEAR C and GEAR D  jump 90 degrees, then only rotates 90 degrees, then jumps 90 degrees over and over and over again.
3. In Gearotic 1, I was able to set the home/starting position of any gear in a given gear train and if that particular gear was driven from a shaft of its drive gear, only the gears being driven ahead of that gear would be affected.  Example ? If GEAR C?s home position was changed only GEAR C and GEAR D would be modified and GEAR A and GEAR B would remain the same.  Will we be able to modify the home / starting position settings in the future?

If this has already been discussed please point me to the sunshine, much would be appreciated.

Cheers,
Mark

Hi Mark:

  tis appears to be a bug. Leave it with me and Ill issue a fix for it very shortly.

The feature to rotate a particular gear will be available soon as well, its one I developed and neglected to tie in properly.

Thx

Hi Mark:

New version 2.007 is online which, though it doesn't totally fix the error, makes it much much better. Im working on a more permanent solution.
Also, on the properties tab on the bottom you'll see two new buttons for shaft alignment. SO long as a gear is shaft driven you may now position it as you wish.

Thx

Thank you so much Art, much is appreciated for the update.

Hi Art,
A question - when designing elliptical gears I keep getting a message about teeth not meshing and suggesting I add or remove teeth.  Any hints on how many?

John:

  When you see such a message it usually means to add 1 or remove 1. And its not always necessary. Generally you want gears of one order and size to be identical. This means their interchangable. BUT, in some elliptical combinations, it isnt possible to have for example 2 even tooth count gears that mesh  without moving the teeth on one gear. ( kinda like a chainsaw slides its teeth around its pitchline.). The program will warn when it does that just to say if you have another tooth on one or the other this sliding wouldnt be necessary and both gears could have a space at zero degrees.
  This is only importantr if for example you wish to chain a lot of gears in a train, its nice if their identical in tooth positioning, otherwise what you
have is a special set that only mesh together... nothing wrong with that..just nice to know. So G2 tells you. This situation only happens in certain combinations of different orders and with modified ellipticals which tend to be special set types anyway.

Mark:

  fyi:  The elliptical jump error has been resolved and the complete fix will be in the next update of the program.
