ENZFELDER GmbH Power transmission and lifting engineering OR Spindle gear cubic Type BG

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...

Mounting Spindle gears 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. The alignment and correct positioning of the spindle gear must be done very carefully as no side forces should act on spindle and guide rings. In lifting systems the spindle noses (in case of the basic type) or the traveling nuts (in case of the traveling nut type) must 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:...
