Your entries will be also confirmed and the calculation results will displayed automatically. Load peak frequency factor Friction factor Please note: Material selection for shaft and xin. Own input You can specify different supporting length for the shaft and hub. Thus, the reduced load capacity of the parallel key is considered by the kegway factor.

That applies for shaft, hub and parallel key. Technical data GN A parallel key is a positive shaft-hub-connection. In addition, the proof of strength for the shaft is carried out according to the nominal stress concept. All important calculation results will be calculated during every input and will be displayed in the result panel.

Types of retaining magnets. It can be determined according to DINfigure 6. Input of the values. The maximum torques in reverse direction against the main load direction do not exceed the effective part of the minimum friction torque. The friction factor considers that. The parallel key forms from A to J are also available. Scribd is the worlds largest social reading and publishing site.

DIN /1 keyways | Elesa

Parallel key types E to J The supporting length for the different types of parallel keys is calculated as follows: From experience, the supporting effect for hubs is larger due to the higher stressed material volume than for shafts and parallel keys see table: Enter the following values into the input fields: Parallel key steel stainless steel example for ordering. General Overview For the proof of strength of parallel keys, it is necessary to check keywsy following factors: Subscribe to the Newsletter For the latest information on Elesa products and services.


A clearance fit or interference fit adversely affects the shaft strength. For parallel keys whose parts are made of metallic materials Geometry and parallel key lengths according to DIN DIN has to be considered for the shaft strength, hub design and hub wall thickness must also be considered Mainly for parallel keys used in mechanical engineering for the temperature range of C to C The method B has to be applied.

This message window displays detailed information, helpful hints or warnings about problems. Din thread runouts and thread undercuts for iso metric threads as in din 1. 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 Heavy Shocks: For brittle materials e.

The progress of for ductile and brittle materials over the frequency is shown in figure 5 according to DIN Calculation results In our calculation example the safeties for the shaft, the hub and the parallel key are marked red.

Guidelines for the choice. Parallel key types A to D.

The calculation method B requires some additional inputs. We appreciate your feedback and we are looking for ideas, suggestions or criticism. There are two different cases: Keyway tolerances for shafts keyword found websites listing. Subscribe to the Newsletter For the latest information on Elesa products and services. Nevertheless, please continue to input the data as usual. A check of the maximum surface pressure is not necessary according to DIN For other ratiosthe values are determined from two diagrams by interpolation.


No-slip disks for levelling elements. In case 2, the changes of load direction factor is dependent upon the frequency of changes of load direction for the parallel key. The supporting length is determined from the standard length and the chosen parallel key type. Method C It is a rough calculation of the surface pressure and resulting estimation of the shaft stress.

You can also select the geometry and size of the parallel key. Width of hub within. The database allows you to choose the material. The joint pressure, that is reduced due to the parallel key in comparison to the hole without keyway, is considered by the factor. Constant surface pressure over the keyway length and height of keyway wall No consideration of chamfers or radii for the determination of supporting surfaces Limitations: You can navigate through the report via the table of contents that provides links to the input values, results and figures.
