Servo Worm Gears feature optimized hollow-flank teeth.

Press Release Summary:

Available in 050, 063, 080, and 100 sizes, V-Drive+ offers hollow shaft, smooth/keyed/involute shaft, and flange output options. Units feature torsional backlash of less than 3 arc-min and efficiencies up to 97%. For low duty applications, V-Drive economy comes in 050 and 063 sizes with hollow shaft and shaft/smooth/keyed output options. Torsional backlash is less than 8 arc-min.

Original Press Release:

New Generation of Worm Gear Launched

Introducing the V-Drive+ and V-Drive economy - optimized manufacturing leads to superior product

Wittenstein has enhanced the alpha V-Drive® servo worm gear, offering variety for applications and bringing the worm gear to a new level. The improved range of V-Drive+ boasts optimized hollow-flank teeth for accuracy and low backlash, 50% more torque and 97% efficiencies - the highest for servo worm gears on the market.

The new generation of the V-Drive® gearbox comes in two versions: V-Drive+ & V-Drive economy.

Two important changes which have occurred for the technical specifications on this product are 1) T2B is now T2max and means the maximum torque which can be transmitted by the gear box and 2) T2N is now T2servo and means the maximum torque which can be transmitted by the gear box with a minimal increase in backlash over the whole lifetime of the gearbox.

This product replaces the classic version of the V-Drive®. With continuously high positioning accuracy and low backlash of <3 arcmin, the V-Drive+ sets new standards. The V-Drive+ is available in these output options: VDH (hollow shaft), VDS (smooth/keyed/involute shaft) and VDT (flange).

Features of the V-Drive+ include:

- Sizes 050, 063, 080, 100

- Ratio 4, 7, 10, 16, 28, 40

- Torsional backlash < 3 arcmin

- Efficiencies of up to 97%

V-Drive economy

Quality with maximum returns (shown in the photo without paint)

A new low cost solution for low duty applications has been added to the family. Wittenstein quality combined with optimized hollow-flank teeth provides more torque and power density than other worm gear alternatives. The following output options are available for the V-Drive economy: VDH (hollow shaft), VDS (shaft, smooth/keyed)

Features of the V-Drive economy include:

- Sizes 050, 063

- Ratio 7, 10, 16, 28, 40

- Torsional backlash < 8 arcmin
