Application Information
|
Intended Use
The Compensator is intended to be used in "peg-in-hole"-type operations in the
vertical orientation. The "peg-in-hole" example is an application
involving the insertion of one part into another. There are a variety of
"peg-in-hole"-type applications that include: dowel pin insertion, mold
alignment, washer insertion, the insertion of bearings into housings, and the
insertion of shafts into bearings. If the Compensator is used in the
horizontal orientation, over time, the shear pads will develop sag.
Rubber and most rubber-like materials have memorization characteristics.
Over time, the rubber material memorizes the repeated position and will return
to this position. When this occurs, the shear pads have developed
sag. Use of the lock-up option is recommended to prevent shear pad sag.

Contact Force
Excessive contact force is the main problem in many assembly applications.
Excessive contact force causes galling, jamming, and broken parts. During
typical assembly processes, there are three main contact forces: single-point,
sliding, and two-point (see figure below). The key to reducing
single-point or sliding contact force is to use a compliance device with low
lateral stiffness. Two-point contact force is reduced by a compliance
device with a low cocking stiffness.
