The spiral gear is mounted on a sturdy countershaft of the Cone Crusher, which rides in bronze bushings. The gears are precision cut for …

Work is the result of a force acting over some distance. Work is quantified in joules (Nm) or foot-pounds. Torque is a rotating force produced by a motor's crankshaft. The more torque the motor produces, the greater is its ability to perform work. Since torque is a vector acting in a direction it is commonly quantified by the units Nm or pound-feet.
