9116 Series Compensator
Description
|
|
The base 9116 Series Compensator includes anodized aluminum top and bottom
plates, hardened steel overload pins, and shear pads. The 000
and 100 sizes use 3 shear pads. The 200 size uses either 3 or 6 shear pads. The 400 size uses either
6 or
12 shear pads. Units with lock-up include an air cylinder, bearing plate, lock-up
screws and lock-up screw bushings. Units with lock-sensing also require a
sensor fitting and a cabled proximity sensor.

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.
