Working Characteristics of the Driven Machine. Stress resistance of technopolymer adjustable handles. Case-hardened steel according to DIN 17 For a dynamic load, an interference fit stops the occurrence of fretting corrosion. Gray cast iron with lamellar graphite according to DIN and For shaft keyway wall For hub keyway wall Sales Team Windows dialog for saving the file.
Parallel Keys – Type A, round-ended without retaining screw – Part 3
Move the mouse pointer to an input field or a button, then you will keywah some additional information. That applies for shaft, hub and parallel key.
ELESA is constantly engaged in the development of new and innovative solutions. In case 2, the changes of load direction factor is dependent upon the frequency of changes of load direction keywwy the parallel key. Regardless of the torque flow direction, three cases are distinguished. This item has been successfully added to your list.

These diagrams are integrated into the calculation module and are valid for a specific ratio. Alternating load of the parallel key during alternating load direction. Automatic dimensioning of the supporting length. The database allows you to select a parallel key. Din thread runouts and thread undercuts for fin metric threads as in din 1. Technical data and guidelines for the choice. Place a checkmark in order to enable the input field and enter a value for the supporting length.
One-sided load of the parallel key during alternating load direction. 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.
No-slip disks for levelling elements. Thus, the friction torque, effective for the power transmission, is decreased. Friction factor Please note: 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: 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.
One of the main benefits of the program is that the software provides suggestions for correcting errors during the data input. In order to do so, please click the calculator button next to the input field of the shaft diameter. Ketway also get detailed information on the kind of material, hardness factoryield point as well as support factor.
From experience, the supporting effect for hubs is larger due to the higher stressed material volume than for shafts and parallel keys see table: Message window Minimum Safety: According to DINthis can be obtained for a hole without keyway. With the maximum load peak torqueoccurring during the entire operation time, it applies: Calculation results In our calculation example the safeties for the shaft, the hub and the parallel key are marked red.

Scribd is the worlds largest social reading and publishing site. For brittle materials e.
For method B, the chamfer on the shaft and hub keyway is additionally integrated into the calculation. Guidelines for the choice. By the hardness influence factor, an increasing of the permissible surface pressure is considered see table: No alternating torque – load in only one direction Alternating torque with a slow torque increase Alternating torque with a fast torque increase Changes of load direction Maximum reverse torque Small outer diameter of stepped hub Large outer diameter of stepped hub Width of hub with within Axial distance between load in and output position Chamfer on the shaft keyway edge Chamfer on the hub keyway edge Selection dialog for the parallel key.
The parallel key can be used with limitations also for swelling and alternating torques. The progress of for ductile and brittle materials over the frequency is shown ein figure 5 according to DIN The parallel key forms A to J as well as the parallel keeyway size, including the lengths, can be selected.
You can also select the geometry and size of the parallel key. The alternative outer diameter is calculated as follows: Special cases may occur due to starting impacts, short-circuit torques, emergency breaking torques, abrupt blockings etc.
General Overview For the proof of strength of parallel keys, it is necessary to check the following factors:
