10.4 Sound power level
SIMOGEAR geared motors have noise levels below the permissible noise levels defined for
gearboxes in VDI guideline 2159 and for motors in IEC 60034-9. In conjunction with
gearboxes, the motor noise values L
pfA or LWA increase on average by 3 dB (A).
The circumferential velocity of the motor pinion has a significant influence on the additional
gearbox noise. As a consequence, higher speeds or lower ratios result in higher noise.
External noise
Noise not generated by the gearbox but emitted from it are not taken into consideration.
Noise emitted by the drive and driven machines or the base are also not taken into
consideration. Even when the noise from the gearbox have been transferred there.
10.5 Mounting positions
10.5.1 General notes on mounting positions
Only operate the gearbox in the mounting position specified on the rating plate. This ensures
that the correct quantity of lubricant is provided. The symbols are shown for the standard
mounting position.
Note
Gearbox sizes 19 and 29
Gearbox sizes 19 and 29 are lubricated for life. There is no opening to check the oil level.
In mounting pos
itions M2 and M4 the gearboxes are equipped with a breather valve.
C29 has a breather valve in all mounting positions.
