THE APPLICATION PROCESS• Max Thrust

– Thrust/Load affects whether a belt or screw drive is selected

SPEED



[email protected]

Sold & Serviced By:


Speed Decisions

• Maximum Speed– The maximum rate at which the load is moved (inches per

second)



[email protected]

Sold & Serviced By:


Speed Decisions• Belt Drive or Screw Drive?

Belt Drive• Max speed 200

inches/sec.

Screw Drive• Max speed varies with

• Screw pitch • Screw length• Nut design



[email protected]

Sold & Serviced By:


Speed Decisions• Maximum speed and stroke length is limited by screw wobble

(critical speed)– As the stroke length increases the distance between bearing supports increases

causing a “jump rope” effect within the screw



[email protected]

Sold & Serviced By:


Speed Decisions• Motor

– May exceed maximum RPM limit• Along with desired speed, the screw pitch and any reductions (gearheads or

pulleys) affect the motor RPM.

Sold & Serviced By:

• Accuracy– How close you come to the target, though not necessarily

the same position• Repeatability

– How close to the same location, even if not close to the target

• Resolution– Smallest increment of movement
