Precision single universal joints tea machine components. Technical data and guidelines for the choice. The friction factor considers that. The method Keyday has to be applied. Parallel keys din form a st round heads st import from excel copy the product rows from excel by selecting adjacent columns where the first one. Additionally, there is the possibility to enter the number of decimal places for the output of the numerical values in the report.

Bright steel according to DIN Automatic dimensioning of the shaft diameter. Small outer diameter of stepped hub Large outer diameter of stepped hub Distance between the axial cutting planes through N and W Width of the hub with within the carrying part of the parallel key, i.


Calculation method B Please note: You also get detailed information on the kind of material, hardness factoryield point as well as support factor. Calculation report You may also print or save the calculation report: Regardless of the torque flow direction, three cases are distinguished.

Therefore, a chamfer and radius on the parallel key as well as on the shaft and hub keyway edge are considered according to the figure above: Your subscription for the Elesa Newsletter has been sent successfully.

Kind of load application For a stepped hub, it means see above figure: Place a checkmark in order to enable the input field and enter a value for the supporting length. Load peak frequency factor In case there is no material that will fulfill the design requirements, then simply define your individual material.

It is recommended to use the calculation method B. You can define the geometry of parallel keys as you wish and different from the DIN standard. In this case, the surface pressure, occurring in the parallel key, is not relevant. Select method B from the listbox.

I consent to the processing of my personal data in accordance with the Privacy Policy. General Overview For the proof of strength of parallel keys, it is necessary to check the following factors: Method C It is a rough calculation of the surface pressure and resulting estimation of the shaft stress. Parallel key according to din highsized version, b 10 mm, h. New parallel key However, it is integrated into the calculation. The safety can even be increased by selecting another material.


Parallel key types A to D.

11 Parallel Key Calculation According to DIN

However, the rating life is limited if it comes to constant slipping between shaft and hub 68885 thus to a deflection of the parallel key connection. Types of retaining magnets. For shaft keyway wall For hub keyway wall The different keyway depths in shaft and hub as well as the chamfer of the parallel key are taken into consideration for the calculation. Rubber extruders, continuously operating mixers for rubber and plastics, ball mills lightwood-working machines gang saws, lathesbillet rolling mills, lifting gear, single cylinder piston pumps 6885 Shocks: Automatic dimensioning of the supporting length.
