4.3.1 General information about the assembly of drive systems
( Stop!
The lubricant fill quantity of the gearboxes is matched to the mounting
position. The mounting position indicated on the nameplate must be
observed to avoid damage to the gearbox.
¯ Take safety measures prior to any operation:
– Disconnect the machine from the mains, ensure standstill of the drive system
and avoid any machine movement.
– Check faultless state of the drive system. Never install and commission
damaged drive systems.
– Check drive function - machine function assignment. Check direction of rotation
(¶ 46).
¯ The mounting areas / the foundation:
– must be plane, torsionally rigid, and free from vibrations,
– must be suited to absorb the forces and torques generated during operation,
– should have vibration−absorbing properties.
¯ Align drive system on mounting surfaces exactly with the machine shaft to be
driven.
– Be sure to carry out mounting in a manner free from distortion, in order to avoid
additional loads.
– Even out slight inaccuracies by the use of suitable flexible couplings.
¯ Support reaction torque by suitable measures.
¯ Be absolutely sure to secure fastening fixtures of accessories and built−on
accessories against unintended loosening. We recommend:
– the use of screws with a minimum property class of 8.8.
– with steel or cast iron output flanges, in particular for applications with an
alternating load, the use of screws with a strength of 10.9 with correspondingly
high tightening torques.
– Secure screwed connections with medium strength using screw locking
adhesive.
