  • Gear Tooth Form
    Gear tooth geometry is determined primarily by pitch, depth, and pressure angle. Standard pitches are usually whole numbers when measured as diametral pitch , the ratio of the number of teeth to the pitch diameter in inches. Coarse-pitch gearing has teeth larger than 20 diametral pitch -- usually
  • It's a swing and a miss
    , release pin, control valves, and pressure gages. 5 to 15 from horizontal Maximum error in angle positions Maximum error in spin rate For many diehard baseball fans, the coming of spring heralds trips to the batting cages and a few sessions in front of a pitching machine. Since the first organized
  • Rotary Actuators
    , the outer spline engages the ring gear and causes sleeve rotation. At the same time, the inner spline engages another set of helical teeth on the output shaft. This causes relative shaft rotation in addition to that of the piston sleeve. increase helix angle and reduce actuator length by replacing
