For a safe calculation, the eAssistant software uses the most conservative case and this exceptional case will not be considered automatically.
Assembly instructions are available for download here. The torque is transmitted from the shaft to the hub via the parallel key.
The method B has to be applied. For the load peak torque is transmitted by friction. The frequency of the load peaks has to be estimated keysay the entire operating time. Parallel key steel stainless steel example for ordering. For a dynamic load, an interference fit stops the occurrence of fretting corrosion.
Dimensioning button for 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. Technical data GN The main purpose of kewyay parallel key is to transmit static and quasi-static torques. We appreciate your feedback and we are looking for ideas, ksyway or criticism.
Method B The dimensioning takes place due to a detailed consideration of the occurring surface pressures. Technical data and guidelines for the choice.
If you check the message window carefully for any errors or warnings and follow the hints, you are able to dn a solution to quickly resolve calculation problems. The following dimensioning functions calculator button provide you with optimal support: The maximum torques in reverse direction against the main load direction do not exceed the effective part of the minimum friction torque. The load peak frequency factor evaluates the influence of the load peaks on the maximum surface pressure.
According to DINthis can be obtained for a hole without keyway. Secure pdf files include digital rights management drm software.
Subscribe to the Newsletter For the latest information on Elesa products and services. Supporting length and number of parallel key.
KEYS : KEYS ISO B UNI B DIN B – Gandini Fasteners
General Overview For the proof of strength of parallel keys, it is necessary to check the following factors: For this case, according to DINthe length of each extended part may be calculated as carrying up to maximum. Desch hrc couplings with taper bush have the advantage that even with greater shaft tolerances. These files are related to p9 keyway tolerance chart.
Supporting length for shaft and hub. Automatic dimension of the standard length.

You keywag define the geometry of parallel keys as you wish and different from the DIN standard. If you click on the dimensioning buttons, you get a suggestion for an appropriate input value.
Kind of load application. With the maximum load peak torqueoccurring during the entire operation time, it applies: Parallel key according to din highsized version, b 10 mm, h. This item has been successfully added: No-slip disks for levelling elements. Steady load current generator, uniformly loaded conveyor belt or platform conveyor, worm conveyor, light lifts, packing machinery, feed drives for machine tools, ventilators, light-weight centrifuges, centrifugal pumps, agitators and mixers for light liquids or uniform density materials, shears, presses, stamping machines, vertical gear, running gear Light Shocks: Stress resistance of technopolymer adjustable handles.
One of the main benefits of the program is that the software provides suggestions for correcting errors during the data input. Automatic dimensioning of the shaft diameter. These diagrams are integrated into the calculation module and djn valid for a specific ratio. 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: Warnings for an effective protection keyyway the Reed switches.
The factor is dependent upon the kind of load in and output position. That applies for shaft, hub and parallel key. Regardless of the torque flow direction, three cases are distinguished. Load peak frequency factor The calculation can be run by using unusual metallic materials. Calculation method B Please note: The calculation method B requires some additional inputs.
Number of parallel keys For an inversion of the torque direction, method C cannot be used.
Parallel Keys – Type A, round-ended without retaining screw – Part 3
Surface pressure on the shaft, parallel key and hub Design strength of the shaft for Torsional stress, normally quasi- static Bending load, normally dynamic Consideration of notch effects, for that the strength calculation for the shaft according to DIN is usually used Design strength of the hub In DIN a distinction is made between different methods for the proof of strength for parallel keys: Keyway tolerances for shafts keyword after analyzing the system lists the list of keywords related and the list of websites with related content.
Technical data GN Precision single universal joints tea machine components. Depending onthe factor is determined by using the figures 3, 4 and 5 in DIN Tooltip The quick info feature gives you additional information about all input fields and buttons.
