Gearbox Planetary gearbox 5.3.3 LP+ series 5.3.3.1 Overview 5.3.3.2 Benefits 1FK7 motors can be combined with planetary gearboxes to form compact coaxial drive units. The gearboxes are flanged directly to the drive end of the motors. When selecting the gearboxes, ensure that the permissible speed of the gearbox is not exceeded by the maximum speed of the motor. For high operating frequencies an allowance factor f2 must be taken into account, refer to Configuration Manual "General Section for Synchronous Motors". The frictional losses of the gearbox must always be taken into account when engineering geared drives. The gearboxes are only available in a non-balanced design and with key. • High efficiency, single-stage: > 97 % • Torsional backlash, single-stage: ≤ 12 arcmin • Power transmission from the central sun wheel to the planetary pinions • No shaft deflections in the planetary gear set due to the symmetrical force distribution • The gearboxes are connected to the motor shaft via an integrated clamping hub. A plain motor shaft end is required for this, while radial eccentricity tolerance N to DIN 42955 and vibration severity grade N to EN60034-14 are sufficient. The motor flange is adapted via adapter plates. • Output shaft of gearbox exactly coaxial with the motor • The gearboxes can be mounted in any position • The gearboxes are sealed (seal between gearbox and motor) and filled with grease in the factory. They are lubricated and sealed for their service life. • Gear unit degree of protection IP64 • Small dimensions • Low weight 1FK7 Synchronous Motors 5-42 Configuration Manual (PFK7), 10/2005 Edition, 6SN1197-0AD06-0BP1
5.3.3.3 Integration Gearbox Planetary gearbox 1FK702 to 1FK710 synchronous motors are supplied ex factor (SIEMENS) complete with planetary gearbox mounted through a flange. The gearboxes assigned to the individual motors as well as the gearbox ratios, available for these motor-gearbox combinations are listed in the Selection and ordering data table. When making a selection, the maximum permissible input speed of the gearbox must be observed (this is the same as the maximum motor speed). The motor/gearbox combinations listed in the selection tables are mainly intended for cycle operation S3 - 60 % (ON time ≤ 60 % and ≤ 20 min). Reduced maximum motor speeds and output torques apply for use in S1 continuous duty (ON time > 60 % or > 20 min). The gearbox temperature may not exceed 90 °C and the maximum permissible input speed is limited from a time perspective. It must be ensured that the geared motors have adequate cooling through convection. The gearbox must be able to dissipate sufficient heat through its flange. Generally, planetary gearboxes can be used for ambient temperatures of between 0 ° and 40 °C. Temperatures down to -15 °C can be handled when special measures are applied (mechanical design measures, appropriate selection of lubricants etc.). 1FK7 synchronous motors to be implemented as follows for mounting to a gearbox: • with plain motor shaft end • Radial eccentricity tolerance N • Degree of protection IP64 • Anthracite paint finish 1FK7 Synchronous Motors Configuration Manual (PFK7), 10/2005 Edition, 6SN1197-0AD06-0BP1 5-43
