و المحتوى كما يلي :

Some motion applications need axes to deliver both linear and rotary
motion. Conventional designs for such functionality are often complicated
and bulky. What’s more, rotary motors put to linear motion often have
output shafts that are inadequate for supporting heavy side loads.
In contrast, dual-motion actuators from Haydon Kerk of AMETEK Advanced Motion Solutions
(AMS) are compact designs specifically designed to deliver linear and rotary motion. Patented
features integrated with standard hybrid stepper-motor technology make for actuators that
LINEAR MOTION
FAQsreplace (and improve upon) more complicated solutions. In
addition, the linear and rotary motions are fully independent
— so dual-motion actuators can even lock an axis’ linear
motion while executing a rotary-motion task. Consider some
dual-motion actuator applications:
• In automated lift latches, dual-motion actuators linearly
push a mechanism forward and then rotate it out of the
way to clear for a device. In a similar way, the actuators
serve in an array of door assemblies — often lifting and
moving doors out of the way to accommodate flow of
parts and materials.
• Dual-motion actuators successfully drive shafts
in laparoscopic instruments and other miniature
medical devices that need to selectively and precisely
reciprocate and rotate.
• Robotic pick-and-place applications might use dualmotion actuators to axially move a workpiece to an
insertion position and then rotate that workpiece to
screw it into place.
Haydon Kerk 35000 Series (Size 14) dual-motion
actuators simplify designs by replacing more
complicated mechanisms. The actuators also output
linear and rotary motions that are fully independent.
Values shown here are based on a 100% duty cycle
for one suite of actuator variations.

Haydon Kerk can custom manufacture
dual-motion actuators to application
requirements, and design engineers can
set numerous operating parameters during
integration … as dual-motion actuators accept
controls via standard two-axis stepper-motor
drives, chopper drives, and microstepping drives.
Below is a chart of the capabilities of two Haydon Kerk
dual-motion actuator models — the 35000 Series based
on a Size 14 hybrid stepper motor and the 43000 Series
based on a Size 17 hybrid stepper motor. Note that standard
strokes are 1, 2, and 4 in. (25.4, 50.8, and 101.6 mm). Standard
motors are Class B rated to 130° C.
