P-88x.x5 Piezo Actuator
5.3
Applying the Load
The P-88x.x5 can be coupled to a load in various ways, depending on the application:
Gluing the piezo actuator (p. 19) into the mechanical system to be moved or into a
flexure
Using a ball tip:
−
Gluing a hardened ball tip, which establishes a single-point contact to an even
surface
−
Gluing a hardened ball tip, which establishes a ring-shaped contact to a calotte
INFORMATION
Diagrams showing how to couple the P-88x.x5 to a load can be found in "General Notes on
Installation" (p. 17).
Requirements
You have read and understood the general notes on installation (p. 15).
The P-88x.x5 is discharged (p. 30) and short-circuited (p. 31).
Tools and accessories
Suitable adhesive (e.g., cold-hardening epoxy resin adhesive)
When using a ball tip: Suitable ball tip
When using a flexure: Suitable flexure
Applying the load
Apply the load evenly.
If the piezo actuator is coupled in a milling pocket:
Ensure that there is full-area contact at the end surface of the piezo actuator. For this
purpose, choose the dimensions of the milling pocket correspondingly or make free
cuts in the milling pocket.
If a point load is applied to the end piece of the piezo actuator:
Dimension the end piece so that its thickness corresponds to half the cross-sectional
dimension in order to prevent tensile stress on the piezo actuator.
