Handling
Precise palletising

For highly-dynamic, exact handling of pallets, the swivel axis is of great importance. It is subject to extreme acceleration and braking torques. These loads are especially high in emergency stop situations. The backlash of the swivel axis must also be minimised. That is because with a swivel arm radius of 1.53 metres, for example, even the slightest angle errors significantly impair the positioning precision. Therefore, a pivot arm drive must be able to meet the highest demands on load capacity, reliability and precision. The RV 160-E high-reduction precision gear from Nabtesco more than satisfies these requirements. Its arguments:

• Acceleration torque: 3,920 Nm
• Rated torque: 1,568 Nm
• Emergency stop torque: 5 times the rated torque
• Compact diameter: 280 mm
• Reduction ratio: i=171
