V-Drive Technical brochure Maximum power density Constant torsional backlash Supreme smooth running

V-Drive Basic – The quiet endurance runner Servo worm gearheads with output shaft and hollow shaft. The gearing of the V-Drive Basic was specifically developed to minimize the noise level in S1 operation. It also convinces with optimal value for money and short delivery times. V-Drive Advanced – The flexible powerhouse Powerful servo worm gearheads with flexible output configurations. In addition to a very high power density, the V-Drive Advanced achieves a constant, low torsional backlash throughout its lifespan. It is suitable for both cyclic and continuous duty applications.

Account must be taken of the radial and axial forces at the output: Please also carry out steps 6 and 7 if forces are present at the output (e.g. if timing belt pulleys, pinions or levers are mounted there). Step 6 (if external forces are present): Determine the forces acting on the output and check the boundary conditions Radial force distance x2 =[mm] Axial force N] Axial force distance y2 =[mm] (required if F2a is present) Conditions if axial force F2a is present: 1.
