The Motorized
SplineRail utilizes a Kerk precision
rolled lead screw, supported by bearings and contained within a concentric
aluminum spline, driving an integrated Kerkite composite polymer nut/bushing. The
extruded aluminum spline offers torsional stability. Haydon Kerk says the KerKote
TFE coating and self-lubricating Kerkite nut/ bushing material ensures long life
and zero maintenance. The motorized version of the SplineRail uses the Haydon
Size 17 single stack or double stack stepper motor.
When mounted vertically, the SplineRail can
also be used to simultaneously lift and rotate (Z-theta motion). With one motor
driving the screw and a second rotating the rail, a compact, self-supporting
pick and place mechanism can be created. Screw leads are available from 0.05 to
1.2 inch per revolution providing a wide range of performance profiles,
including self-locking threads that can support a load without external power
or breaks.
Typical applications include pick-and-place
mechanisms and robotic assemblies in life sciences instrumentation,
semiconductor equipment, business machines, packaging and assembly, and a wide
range of factory automation applications.
