Power Flow from Motor to Spindle: With Diagram | Lathe | Industrial Engineering

The power flows from the motor in the base to the cone-pulley by means of a belt. The belt can be adjusted to three or four positions to vary the spindle-speed. Fig. 12.15 gives the idea as to how the different spindle speeds can be obtained. Various spindle speeds can be obtained by shifting the belt on different steps of [...]
