5 Mechanical installation
5.1 Important notes
Danger!
Some of the motors mounted to the gearboxes are equipped with
transport aids. They are only intended for the mounting/dismounting of
the motor to the gearbox and must not be used for the entire geared
motor!
• Only move the drive with means of transport or hoists that have sufficient
load-bearing capacity.
• Ensure safe fixing.
• Avoid shocks!
5.2 Preparation
Remove the corrosion protection from the shaft ends and flanges. If necessary, remove
dirt using standard cleaning solvents.
Stop!
Bearings or seals must not come into contact with the solvent - material
damages.
After a long storage period (> 1 year) you have to check whether moisture has
entered the motor. For this purpose, measure the insulation resistance (measuring
voltage 500 V
DC
). In case of values 1kper volt of rated voltage, dry the winding.
5.3 Assembly of built-on accessories
Follow these instructions carefully. Please note that the warranty and product liability
will become void in the event of impermissible alterations or modifications to the
motors.
• Mount the transmission elements:
– Shocks and impacts must be avoided! They could destroy the motor.
– For mounting always use the centre bore in the motor shaft as specified by DIN
332-DR-M...
– Tolerances of the shaft ends:
50 mm: ISO k6, > 50 mm: ISO m6.
• Only use an extractor for the disassembly.
• When using belts for torque/power transmission:
– Tension the belts in a controlled manner.
– Provide protection against accidental contact! During operation, surface
temperatures of up to 140°C are possible.
