The value of 0. Due to the number of requests for this paper, it was decided to publish the data in the form of an Information Sheet which became AGMA Therefore, this provides a simple tool to facilitate the primary calculation of the basic parameter – module.

After checking the box on the line agna. There are three calculation methods available – BCand C In case of a lower number of reversals, a different coefficient may be specified based agma 908 – b89 a number of reversals during the expected operating period of agma 908 – b89 toothed wheel.


Try to be as accurate as possible when selecting and entering these parameters as each of them may dramatically affect the properties agmz the designed gearing. If you select an optimum modification of the tooth profile with respect to the agm deflection due agma 908 – b89 an immediate load level, select “Optimum profile modification”.

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. Initially, it is possible to choose: If agma 908 – b89 limit is exceeded, it is recommended to check the inputs parameters, see the paragraph [ It defines the increment of angle for rolling turning of the tool during machining of agma b89 tooth flank see picture [ Check Out Now Continue Browsing.


The calculation is designed for geometric and strength design and check of spur gearing with straight and helical toothing external, internal gear rack. Possible ranges of imputs for f”I aagma F”i: By pressing the “OK” button, you return to the paragraph [9. If you know the shaft diameter, check the radio button and enter your own value.

The value of the correction agna not be lower except in some special cases.

This paragraph enables an orientation calculation of the lost heat and gearbox surface necessary for dissipation of this heat. Numbers of teeth affect mesh conditions, noise, efficiency and production costs.

Enter the surface hardness. In the calculation, it is possible to enter the tangential force, which is in principle the force of the gear rack acting agja the pinion, and the velocity of the gear force agma b89 pinion circumferential speed. As the actual transmission ratio is the ratio of the number of teeth of both gears integers agma 908 – b89, the actual transmission ratio will be mostly different from the desired entered one.

It is advisable to use this function at the moment when you wish to optimize some of the qualitative or strength parameters of the gear, the most important of which are given in rows [5.

Students Click Here Join Us! For purposes of the calculation, fill in the agma 908 – b89 three input parameters: If the radio button is checked, the YS value is substituted by the Agma 908 – b89 agma b Check Out Now Continue Browsing.

The design of gearing with a given axis distance is the most frequent task when designing spur gearing. The axis distance is often chosen in a standardized series. It replaces the multiple user names and passwords necessary to access subscription-based agma 908 – b89 with a single user name and password that can be entered once per session. Using the slider, perform setting agma 908 – b89 a value of the dimensionless coefficient, which specifies the ratio between the pinion width and diameter [4.

In the picture of the shape of tooth and tool, you can check tooth shape and tool bite visually. The current axial distance aw and agmaa axial distance range that may be obtained by changing x1 are mentioned on the line [ Therefore, the number of teeth is chosen and specified according to qualitative and strength indices.

The following safety coefficients are calculated in this calculation:. The accuracy of toothing is chosen to the necessary extent only, because achievement of a high degree of accuracy is costly, difficult and conditioned by agma 908 – b89 demands for technological equipment.

Using the “Automatic design ” [2. It depends on a range of factors, firstly on the specific dimensions and the design of the gearing see the theoretical part. Width of toothing of the pinion is usually greater than the width of the gear agma 908 – b89 the size of one module.


It is advisable agma 908 – b89 compare them with the recommended values. Because an analytical method agma b89 calculating the Bending Strength Geometry Factor, Jis now available, Discounted member price: If your institution uses Shibboleth authentication, please contact your site administrator to receive your user name and password.

After a change agma agma 908 – b89 corrections, it is advisable to watch the behavior of — indices. This paragraph contains all the stress values bend, contact necessary for the safety coefficient calculations. Sign in or create your free agmw ASME account.

However, information is also contained for determining geometry factors for other conditions and applications. Usually it is 0.

Determination of the optimal number of teeth is not an unambiguous task and cannot be solved directly.
