P-MB planetary gearbox with brake

Properties of P Planetary Gearboxes:

• Various output shaft options:
  • G – Solid smooth shaft
  • P – Solid shaft with keyway
• Gearbox mounting via square flange.
• High precision – standard or reduced backlash.
• No positioning errors – fractional gear ratio.
• Maintenance-free – no oil changes or servicing required.
• Quiet operation – helical gear teeth.
• Flexible mounting position – can be installed in any orientation.
• High torsional stiffness.
• Low inertia moments.
• Continuous operation without additional cooling.
• Sealing: FKM at the input / NBR at the output (optional FKM VITON).
• Optional reinforced axial and radial bearings for the output shaft.
• Rigid output bearing due to preloaded tension.
• Ambient temperature: 0°C to 40°C (other ranges available on request).
• Maximum gearbox housing temperature: ≤ 90°C.
• Protection class: IP65 (optional IP66).
• Synthetic gearbox oil: CLP HC ISO VG 150.
• Standard coating: One primer layer in RAL7001 or RAL9005.
• Optional multiple coatings in any RAL color.
• Special food-grade oils available upon request.
• Optional explosion-proof design compliant with ATEX 2014/34/EU directive.

Properties of MB Adapters with ServoSTOP Brake

• Adapter with integrated brake, combined with a planetary gearbox.
• Functions as a holding brake.
• Braking from full speed, e.g., in case of a voltage drop or emergency shutdown in hazardous situations.
• Can operate as a single brake or in combination with a motor brake for a redundant braking system.
• Electrically released spring-applied brake for dry operation.
• Equipped with a backlash-free plug-in coupling (jaw coupling), allowing easy motor disassembly with the braked shaft in any position.
• Electric release monitoring inside the terminal box using a contactless, wear-resistant proximity switch.
• Manual wear inspection by checking the air gap with a feeler gauge.
• Radial shaft sealing rings made of FKM with double sealing lips.
• Four oil drain holes to protect the brake from oil contamination in case of leakage.
• Differential-redundant system compliant with EN ISO 13849-1.
• Electrical connection: Standard in a junction box; optionally as a plug-in connector (not possible with release monitoring).
• In a de-energized state, braking is applied by spring force.
• The brake is released by a DC electromagnetic coil before the motor is activated.
• Standard motor plug connectors or terminal box/plug connector for the motor adapter are mounted in a 270° position.
• Combined with a motor brake, this solution provides dual braking with an exceptionally compact design.
