TQF Bonfiglioli low-backlash transmission

The low-backlash TQF series of precision planetary flanged gearboxes from Bonfiglioli provides high torsional stiffness for applications such as industrial automation.

The gearboxes are suitable for applications which require high dynamic characteristics and the ability to reliably handle a high number of start-stops and reversals.

The flanged design is suited to machine tools, packaging machines, precision rotary axis drives, travelling gantries, columns and material handling axis drives, as well as tasks requiring high positioning accuracy, dynamic cycling operations, tilting movement and compact solutions for motion control.

Suitable applications include working centres for metal, wood, marble, stone, printing, paper and glass products across diverse industries.

The series is available in five sizes delivering rated output torque ranging from 30 to 800 Nm and acceleration output torque from 45 to 1200 Nm.

The monobloc planet carrier ensures higher radial load capability as well as higher torsional stiffness, offering a high safety factor for transmissible torque and increased dynamic response. Bearings have been selected and sized to suit the torque rating of the gearbox and provide quieter operation. The series features a high level of mechanical protection (IP65), a flanged output (similar to EN ISO 9409) and a low level of acoustic pressure.

Features of the range include: high flexibility for input flanges; modular design to comply with individual needs including features such as smooth shaft/key shaft, standard and reinforced bearings; standard and low backlash and universal design to allow any mounting orientation; servo sizing tool to avoid oversizing.
