Considering replacing intermediate countershaft Viceroy TDS 1/2 PCS
Posted: Sat 13 Mar , 2021 1:15 am
I have a fairly standard setup - 3 phase Hoover motor (1425 RPM), VFD and countershaft.
I am considering replacing the motor with a spare 1 HP 8-pole (680 RPM) motor and ditching the intermediate countershaft.
Issues to consider are the length of a single belt, spindle speed, and torque.
This is currently "under consideration" and I would be interested to know if anyone has done a similar conversion. I am in no way committed to the idea or suggesting it would be a good thing. I'm attracted to the idea of using fixed pulleys, making full use of the VFD and backgear where necessary.
The background to considering this move stems from long-running problems I have encountered with the intermediate pulley adjustment and consequent belt slippage. I have posted about this before (the adjusters were locked up, even though care had been taken to keep the pulley shaft horizontal) and I now have the countershaft and adjusters stripped down for repair/replacement.
If eventually I decide to keep the countershaft it will be in a slightly modified form to make adjustment easier. The existing adjusters are difficult to use (slotted heads - I would prefer hex or a socket) and vulnerable to binding up during adjustment.
