Orac Spindle Pulley Bore + Keyway size

Post by robertspark » Fri 31 Aug , 2018 10:03 am

I was just wondering if anyone knows what diameter the spindle pulley bore is and the keyway size is?

Looking to put a taper lock HTD pulley on it with a servo motor to upgrade an indexing spindle.

Thanks,

Rob

Spindle pulley is 30mm dia, keyway is ~8mm wide and ~3mm deep (into the pulley)

Spindle pulley is ~61.7mm dia

Motor pulley is ~ 34.7mm dia

Pulley ratio is therefore ~ 1.778:1
