Mechanical installation
Important notes
•
Install the product according to the information in the chapter "Standards and operating
conditions".
Standards and operating conditions
•
The technical data and the data regarding the supply conditions can be found on the
nameplate and in this documentation.
•
Ambient media − especially chemically aggressive ones − may damage shaft sealing rings,
lacquers and plastics.
•
Lenze offers special surface and corrosion protection in this case.
Preparation
•
Protect shaft sealing rings from contact with solvents.
•
Remove protection covers from shafts.
•
Thoroughly remove anticorrosion agents from the shaft and from flange faces.
•
Draw the transmission elements onto the output shaft only by using the centering thread.
•
Align the output shaft and transmission elements exactly to avoid tensions.
•
Mount belt pulleys, sprockets, or gear wheels as close as possible to the shaft shoulder in
order to keep the bending load of the shaft and the bearing forces at a minimum level.
•
Tighten all screw connections with the specified torques and secure them with standard
screw locking adhesive.
•
Check paint for damage and repair professionally.
Installation
•
The mounting surfaces must be plane, torsionally rigid and free from vibrations.
•
The mounting areas must be suited to absorb the forces and torques generated during
operation.
•
Ensure an unhindered ventilation.
•
For versions with a fan, keep a minimum distance of 10 % from the outside diameter of the
fan cover in intake direction.
