VARIO VE31

Adaptable in anygiven situation

Compact. Flexible. Variable.

VARIO VE31Our Worm gear

generation-type VARIO:

Depending on the requirement, the basic VARIO-

gear-housing will be combined either with

covers, feet or flanges. Therefore, the design is

comparable with the previous gear drives, since

all measurements for attachment like pitch-

circle, position of holes, axial measurements etc.

are identical. The rating was optimized and the

efficiency was notably upgraded. Similarly, the

compatibility with installed previous gear-types

made by Groschopp could be maintained.

In addition, the VARIO-system can cater for

specific structural demands in order to realize

special designs, e.g. gears made of stainless

steel. In this way, not only an innovative solution

is found, but also an optimal ratio between price

and output.

Groschopp completes their portfolio of drive-

techniques with the VARIO-gear-models.

The worm gear drive VE31 is a member of the VARIO-gear-type products. It has proved itself extremely

successful on the market. The VARIO-products are designed in a modular design; hence, the VE31 gear

is adaptable to fit any given application.

GROSCHOPP

is a leading manufacturer in the area of electric motor-drive

techniques. Groschopp develops, produces and distributes

customer-orientated drive-solutions, taking into account

many years of experience in a quality-conscious ambience.

We try new paths time and time again, especially in our role

as OEM-supplier, thus setting standards in the area of drive-

applications.
