Linear drives

The linear gear units find a broad application in many fields of the industry, where controlled stroke, shifting and tipping are required.

The advatage of our drives is in the self-locking properties of the units after stopping the input power (motor).

In case of simultaneous use of more units by means of mechanical connection it is possible to achieve a precise, synchrone stroke (also in case of different load of the units).

The driving unit is functionable in every position. The body of the unit has clamping holes on its two sides facing the screw.

This linear gear unit is a combination of a worm gear and a motion screw with traphesoidal thread. The worm as well as the screw are right rotary.

The driving units are delivered in two types:
- Standard gear - SP - on one turn of the worm shaft the screw performs an axial stroke of 1 mm.
- Gear - L - on one turn of the worm shaft the screw performs an axial stroke of 0,25 mm.
Maximal allowed turns of the worm shaft are 2800 rpm.

The drive units are supplied On request with various strokes (maximal stroke for the units is shown in the table).

The units can be produced without driving unit or can be connected with an elektromotor. In the second case a flange is supplied according to the requested motor.
