Hi All,
I have in my possession a variable speed drive manufactured by Metron instruments from Denver Colorado which adjusts the speed of the output shaft relative to the input by a variable adjustable ratio - from 0.1 to 2. The output turns in the opposite direction to the input.
The unit was given to me a number of years ago and I suspect dates from the 1970s. It is in anodised aluminium and is beautifully made. When it was given to me, I was told that it only worked 'a bit' and that it had been opened up to determine why it didn't work. My suspicion is that the very opening was the cause...
I have recently tried to see if I can make it work (again?) and have dismantled it to the limit of my capabilities and I fail to understand exactly how it works and, more importantly, how it can be returned to a functioning state.
In operation it appears to use 2 disks with a pair of wheels between them passing transmission. The variable part is obtained by adjusting the diameter at which the intermediate wheels operate (I think).
Final transmission is through a sun and planet drive.
Questions:
Is anyone familiar with this unit (verrrrrrrrrrrrrrrrrrry long shot!)
Has anyone any idea about how to setup or adjust such a unit?
Simon
