About three years ago I finished a Stuart Turner Oil Field Engine with the Tubalcain gearbox. I fitted an electric motor to drive it. The motor has burnt out and I need to install a new one.
Oil field engines usually run at about 15 stokes per minute. The set up is that the electric motor can have a 1" pulley fitted that drives a 2.625" pulley on shaft 1 in the gear box. The gear on shaft 1 has 15 teeth. It drives shaft 2 on which is Gear 2 of 60 teeth driving a 15 tooth gear that engages on shaft 3 with a 60 tooth gear. The 3rd shaft needs to rotate 15 time per minute.
What is the correct motor speed please?
I think the answer is 2400 rpm and I know I can buy a small motor that runs a 2100 rpm. I can increase the diameter of the 1" pulley somewhat to get the right speed but I confess I'm guessing and I should appreciate some advice confirming the motor speed and the diameter of the pulley on the motor.
