Cycloidal gear reducer / hollow-shaft / for rotary table - 1 471 - 9 807 Nm | NT series
High precision, high output speeds and a high degree of efficiency - these are the demands a drive unit should live up to for use in rotary tables. The NT series from Nabtesco meets these requirements. Thanks to their RV gear design, the NT reduction gears are extremely resistant to impact loads. The hollow shaft enables the central routeing of various cables, media or rotary movements. The contact between the trochoidal disc and housing takes place through rollers. This reduces the wear and increases the service life and reliability.The NT gears offer additional decisive advantages over conventional rotary table drives:
The output achieves and output speed of 100 rpm.
The gears achieve a degree of efficiency of 80 per cent.
The reproducibility lies at +/- 1.0 arc second.
The indexing precision is +/- 2.5 arc seconds.
The assembly times are reduced, because neither an adjustment of the backlash nor the pre-tensioning or the adjustment of the concentricity is necessary.
