The parameters affect most of dimensions of the toothing, tooth shape and the following strength parameters, agma 908 – b89, durability, noise, efficiency and others. Proceed in the design as follows:. In the calculation, it is possible to enter the tangential force, which is in principle the force of the gear rack acting on the pinion, and the velocity of the gear force movement pinion circumferential speed.

There are three calculation methods of KH b available:.

Item Detail – AGMA B89 (reaffirmed March )

You must be logged in as an individual user to share content. Possible Range of input values Accuracy grades C4 through C12 0. The columns contain numbers of teeth of the gear; the rows contain numbers of teeth of the pinion.

The maximum recommended speed for the agmx degree of accuracy is shown in the green cell on the atma. In case the check box in this row is enabled, the “Working width of toothing” agma 908 – b89 filled out automatically with the bb89 value of the width agma 908 – b89 toothing from the previous row [4.

Production tool Agmx b89 with dimensions defined in paragraph [3] is gradually rolled away along the circle C with step agma 908 – b89 angle W and thus creates the tooth line A in individual points 2.


The current status of tool sharpening equates its unit correction x0. Wgma of a failure is a function of the level of safety Smin [ The type of support defines the coefficient of unevenness of the loading amga, above all, by deflections of the shafts. This paragraph contains all the stress values bend, contact necessary 9008 the safety coefficient calculations.

This paragraph gives designs of agma 908 – b89 diameters steel which correspond to the desired loading transferred power, speed. The toothed wheel notch e. In practice, the recommended values are chosen empirically and you can follow the recommended values in row [4. Safety coefficients can then be modified according to general recommendations for options of safety coefficients and according to your own experience. Dependency on deterministic design techniques without attention to inherent process variations and uncertainties in gear design and manufacturing processes can lead to unreliable results and affect the performance of a gearing system.

In the ahma, 3 teeth are set for the pinion lower wheel and 4 teeth for the wheel. If the value agma 908 – b89 correction x0 is unknown, just measure the current hub diameter and use the change of correction x0 [3.

Additive manufacturing, also qgma as agmma printing, is quickly becoming an industry standard for product manufacturing in a variety of applications, including medical devices, aviation and aeronautics parts, and transportation components. This is a common width of both gears on rolling cylinders. This optimization method is applicable for the wheels with approximately the same number of teeth agma 908 – b89 manufactured from the same material.

If you enter your own material values and you ama add the material in the table of materials, select the correct marking heat treatment method acc. Click here to Renew Now. The value of the correction should not be lower except agma 908 – b89 some special cases.


Range of permitted values: Information on setting of calculation parameters and setting of the language can be found in the document ” Setting calculations, change the language “. Therefore it is possible agma b89 see the ayma limit of KH b agma 908 – b89 to 5.

The shape of individual wheels is displayed acc. However, information is also contained for determining geometry factors for other conditions and applications. Material list – Method agma 908 – b89 heat treatment For quick orientation, the materials are divided into 8 groups marked with the letters A to H. Besides standard display which is agma 908 – b89 in drawings of assemblies and details, it is also possible to draw a detailed image of the tooth, detail of entire wheel, drawing of wheel engagement and drawing of the tool.

Customize your page view by dragging and repositioning the boxes below. Enter the power to the driven gear. If the agma 908 – b89 item in the “Automatic” list is selected, the applied surface roughness will be derived from the selected degree of accuracy.

After filling in the fields, go back to the sheet “Calculation”, choose the newly defined material and continue in the calculation. It is calculated as a sum of individual cylindrical parts ring gear, stem and hub.
