Any work on the system on the drives, or on the planetary gearboxes or in
their vicinity may only be carried out by properly trained technical
personnel. The owner of the system must ensure that all persons carrying
out
• installation work,
• maintenance, or
• operational activities
on the system are adequately familiar with the contents of this
documentation as well as with all warnings and precautionary measures
contained therein. Qualified technical personnel are defined as those who
have been trained, instructed or authorized to activate and deactivate,
ground and mark electric circuits and equipment according to the safety
rules and regulations. Qualified technical personnel must possess
appropriate safety equipment and have been trained in first aid.
Adapter plates make it possible to mount the GTM-series gearboxes onto
every Bosch Rexroth servo motor which is mentioned in the type code.
The connection between the motor output shaft and gearbox input shaft is
established via a compression coupling.
Note: When combining Bosch Rexroth motors with GTM gearboxes
always choose motors with smooth shafts.
The motor is centered by using pilot diameter of the Bosch Rexroth motor
and the pilot diameter of the gearbox´s input flange. The compression
couplings are matched to the corresponding motor shaft diameters when
necessary by using a slotted. The bushings are factory-installed so that
the slots in the bushing line up with the slots in the compression coupling
(see Fig. 10-1). This must be confirmed before mounting and any
necessary changes must be made before the motor and gearbox are
assemblied.
Before mounting the servo motors to the gearboxes, all parts have to be
closely checked for damage. All parts should slide easily and without any
force into one another. Damage on the motor shaft or to the compression
coupling of the gearbox can prevent this and must be avoided.
Damage to or contamination on the motor front flange face or on the
gearbox flange face can lead to angular misalignment of the motor shaft
and the gearbox. This can lead to stress on the connection and will have
a negative influence on the life time of the motor and/or the gearbox.
