Shafts - Import export

Spline shafts based on DIN ISO 14 with straight parallel flanks. A spline shaft with spline hub is used to transmit high torques while enabling simultaneous axial movement. The spline shafts are colddrawn. Cold drawing does not interrupt the grain flow of the base material, ensuring spline shafts of very high strength. Tolerances Straightness 0.8 mm/m. Torsion max. 0.5 mm/m. On request Other lengths.

Elastomer NBR. Brace ring and tension spring steel. Rotary shaft lip seals are readytoinstall seals for sealing rotating shafts. They are made from an elastomer outer sleeve and an internal bracing shim. The tension spring ensures increased pressure of the lip against the shaft and supports static sealing. Form A DIN 3760 (ISO 6194/1) version, smooth OD. Form AS DIN 3760 (ISO 6194/0) version, smooth OD with extra dust lip to protect from external dirt. The material NBR has a high wear resistance and is resistant to motor fuels, oil, hydraulic oil and lubricating grease. Operating limits Circumferential speed (m/s) ≤12 Pressure (MPa/bar) ≤0.05/0.5 (rotary shaft lip seals are generally meant for unpressurised operation).

Two-piece shaft collars surround the shaft with a uniformly distributed clamping force. This leads to a dimensionally precise fit and very high retaining forces without damaging the shaft. The shaft tolerance should lie within h11. Two-piece shaft collars can be quickly and easily mounted or removed without dismantling other components.

Steel. Toothed pulleys without aluminium rim flanges. Version Steel phosphated. Aluminium bright. Note Standard HTD profile with metric pitch (halfround toothing). At least one belt pulley must have a rim flange. The toothed belt pulleys have a centre bore or a pilot hole (this can vary due to manufacturing methods). For this reason, the dimension D2 max. given in the table is the maximum diameter of the bore with which the toothed belt pulleys are supplied. This pilot/centre bore can be amended by the customer to produce a reamed bore, reamed bore with keyway or a tapped hole. Alternatively, customers can also use bushes to reduce the bore diameter. The pulleys may be recessed on the sides.

The tension meter is used to perform a pretension test on commercially available belt systems quickly and easily by means of frequency measurement. Fully electronic and equipped with stateoftheart microprocessor technology, the meter enables precise adjustment of all V, toothed and flat belts that have to be tensioned in the range from 10 to 600 Hz. The measurement must never be performed while the drive is running The meter is not permitted or certified for use in potentially explosive areas.
