Kinds of drives
-
Belt drive (LVE 65 / 80 / 100 / 180 / 360)
The belt drive is preferably used for tasks requiring high speed with medium loads and precision. The belt is guided through flaps on the sides and prestressed at the guide carriage. Special antiturn washers make sure the drive is backlash-free and therefore guarantee high repeatability even in case of long ways and high speed. The tooth belt is made of polyurethane and features tensile members made of steel braids – providing sufficient safety for higher loads.
Ball screw drive (LVE 65 / 80 / 100 /180 / 360)
Ball screw drives can be found wherever high feed forces and precision with medium speed are required. The ball screws are available with low or no backlash.
Trapezoidal screw drive (LVE 65 / 80 / 100 /180 / 360)
Trapezoidal screw drives are recommended solutions for medium precision and speed. The duty cycle should not exceed 30 % per hour.
Gear rack drive – on request (LVE 180 / 360)
Gear rack drives can be used to drive several carriages on one guide independently of each other. High speeds with medium positioning precision are possible.

Positioning tables LPT
The modular construction consists of a carriage made of an aluminium alloy with four sealed linear slides and two hardened and precision-ground guide shafts made of steel or stainless steel. The linear slides are aligned in a way to absorb loads from all directions.
The LPT positioning tables are available with shaft dimensions of 08 / 12 / 16 / 20 / 25 /30 /40 /50 mm.
Positioning tables PPT
The positioning tables are available in aluminium and steel versions. All seatings for the guides, the underside of the base plate and the top side of the slide are precisely machined. Ball or roller guides can be used as guiding system according to the load.
The PPT positioning tables are available as standard with the guide sizes
15 / 20 / 25 mm.Other dimensions on request.
Bevel Gear
- Robust cast iron housing

Special designs
Low backlash design
All bevel gears are available with low backlash.
Standard gear sets are available with the following values:S1: i = 1:1 to 2:1 < 6 arc minutes
S2: i = 3:1 to 6:1 < 10 arc minutes
Torsion angles < 6 arc minutes are available.
(Please contact us.)Non-corrosive gears
Non-corrosive gears are suitable for all applications where the drive is in contact with aggressive substances.
As a standard the housings are nickel-plated and tinned afterwards. The shafts are made of stainless steel. The sealings are adapted to the respective application. For special applications the bevel gears are also available in stainless steel design.

Versions
-
SH-G
The linear stroke is carried out by the fixed screw. The screw is led through the jack axially by turning the worm gear. Twisting of the screw must be prevented by the adjacent construction or a twisting protection installed in the jack (VD version). The load to be moved is attached to the end of the screw.
SH-L
The travelling nut moves up and down on the rotating screw. The screw is fixed in the rotating worm gear. The load to be moved is fastened to the travelling nut.
