For our calculation example we specify one parallel key. As a first approximation, can be specified for a parallel key. The following dimensioning functions calculator button provide you with optimal support: The context menu contains all available units.

A recalculation occurs after every data input. Automatic dimensioning of the maximum load peak torque. The joint pressure, that is reduced due to the parallel key in comparison to the hole without keyway, is considered by the factor.
According to DINthis can be obtained for a hole without keyway. Automatic dimensioning of the supporting length. For ketway dynamic load, an interference fit stops the occurrence of fretting corrosion. There are various types of parallel keys – the types A to J 66885 available. For parallel keys whose parts are made of metallic materials Geometry and parallel key lengths according to DIN DIN has to be considered ddin the shaft strength, hub design and hub wall thickness must also be considered Mainly for parallel keys used in 68885 engineering for the temperature range of C to C Geometry and surface pressure on the parallel key connection The supporting keyway depth between parallel key and shaft as well as hub keyway wall are given by the following equations.
You can navigate through the report via the table of contents that provides links to the input values, results and figures. Parallel key steel stainless steel example for ordering. Two cases are distinguished: For brittle materials e. Enter a keyword, a series, a product code 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.

Your entries kkeyway be also confirmed and the calculation results will displayed automatically. Place a checkmark in order to enable the input field and enter a value for the supporting length.
This report contains the calculation method, all input values as well as the detailed results. You will get the results for the equivalent pressure and for the pressure at load peak as well as the safety at operation load and the safety at peak load. ELESA is constantly engaged in the development of new and innovative solutions. The database also provides the standard lengths of the parallel keys.
The parallel key forms A to J as well as the parallel key size, including the lengths, can be selected. For a single load peak, depending on the ductility of the material, the 1,3 to 1,5 times the permanent surface pressure is allowed.
The following strength criteria have to be fulfilled with the appropriate safeties: Secure pdf files include digital rights management drm software. This information will be displayed in the quick info line. Parallel key according to din highsized version, b 10 mm, h 8 mm, l 70 mm, form a roundended, bright. You will get detailed information on the material. Thus, the friction torque, effective ein the power transmission, is decreased.
The different keyway depths in shaft and hub as well as the chamfer of the parallel key are taken into consideration for the calculation. Own input You can specify different supporting length for the shaft and hub. In practice, not more than two parallel keys are used because of the load distribution that is difficult to determine.
