Motor Components 3.4 Gearboxes Gearbox features � Version as planetary gear � Gearbox efficiency: above 95 % � Gearboxes are available for motors, shaft heights 100 to 160 � Selector gearboxes are available up to a drive output of 100 kW � Types of construction: IM B35 (IM V15) and IM B5 (IM V1) are possible 3-66 Note 1PH4 motors are only designed for stress levels in accordance with the specifications (refer to the cantilever force diagram and maximum torque). When using force/torque amplifying elements, e.g. a gearbox, the increased mechanical stress (e.g. from heavy belt pre–tension forces) must be absorbed by using the appropriate reinforcing element. The system planner must take this into consideration. For a gearbox, that means that increased belt pre–tension forces must be absorbed by the gearbox, for example, and transferred to the machine. For drive units where, for example, they are mounted to the gearbox flange or gearbox enclosure, then for motors with type of construction IM B35, they must be supported at the NDE without subjecting the motor frame to any stress.

Example: AC motor without selector gearbox © Siemens AG 2003 – 2006 All rights reserved AC Induction Motors, 1PH4 (APH4) – 04.06 Edition Motor Components 3.4 Gearboxes For P = constant from nN = 1500 rpm to nmax = 6300 rpm a constant power control range greater than 1:4 is possible. Same AC motor with selector gearbox: For gearbox stage i1 = 4 and i2 = 1 a constant power control range of greater than 1:16 is possible (nN’ = 375 rpm to nmax = 6300 rpm). Gearbox mounted outside the spindle box The following advantages are obtained by locating the gearbox outside the spindle box: � Gearbox vibration is not transferred. � Separate lubricating systems for the main spindle (grease) and selector gearbox (oil). � No noise and no temperature fluctuations caused by the gearbox pinion wheels in the spindle box. � Instead of using belts, the drive power can also be transferred from the gearbox out–drive using pinion (on request) or co–axially through an equalizing coupling. Vibration severity level Motor + gearbox: Tolerance level R (acc. to DIN ISO 2373) This is also valid if motor tolerance level S is ordered. Seal between motor flange and gearbox flange There must be a seal between motor flange and gearbox flange for SH 132 and SH 160 due to the uninterrupted centering shoulder with sealing compound (e.g. Terostat 93, Teroson). 3-67
