ENZFELDER GmbH Power transmission and lifting engineering OR FREN Electric cylinder ELZ

History 1969 Mr. Enzfelder established a job shop in Vienna. Equipped with some machinery, the Enzfelder Company manufactured machine parts according to drawings. Within one year the number of employees rose to 3. The Enzfelder company started manufacturing threaded spindles and nuts according to drawings. Then the range of manufacturing was enlarged by toothed wheels, screw wheels and endless screws according to drawings. 1974 The company including the complete manufacture was relocated to Enzesfeld. 1975 The manufacture of spindle gears was launched. The company’s experience in the...

FREN Electric cylinders are an advancement of our standard program. By thought construction is an electrical cylinder in the situation also components out to be taken up. The lift link inside electrical cylinders is protected by the tubing system from any damage by environmental influences and is approximately to rotate secured. In the FREN Electric cylinder there is a robust worm gear pair driving a trapezoid thread spindle. The gear box is made of nodular graphite cast iron 50 fit high loads and meeting high safty standards. The worm is hardened and ground and running on tapered roller...

Mounting Spindle gears without swivelling equipment must be mounted in true alignment on a flat surface which must be so stiff that it can assume the maximal load without oscillations or deformations. In lifting systems the spindle noses (in case of the basic type) or the traveling nuts (in case of the traveling nut type) m ust lie level with each other before the worms of the spindle gears are connected. Before the driving gear is mounted the sense of rotation must be checked: in bevel gear driven lifting systems the sense of rotation can easily be confused; the result would be faulty...

External dimensions For connecting dimensions, the tolerances given in the corresponding drawings are valid. The values where no tolerance is indicated are untoeranced dimensions. The axial backlash of the spindle The axial backlash of the traveling nut in the tubing system is necessary for the building-up of an adequate lubricating film. Wear during operation will increase the axial backlash; please pay attention to our operating and maintenance instructions. Spindle pitch P (mm) max. axial backlash of the threaded spindle as manufactured (mm) max. permissible axial b acklash due to wear...
