The limitations are speeds up to rpm and pitch line velocities not over fpm 35 mps. It is generally recognized that the DINPart 21standard is not suitable for through-hardened gear sets. Several of the variables in the gear tooth rating system in AGMA are allowed a range, resulting in a wide variation of ratings between manufacturers for the same gearbox. There are no agja. Sensitive to coupling lock-up external thrust load.

Shown in Table 1 is typical information on gap widths as a function of the normal diametral pitch Pnd: Less expensive to fabricate gear elements.

This resulted in the allowable stresses being set lower than necessary. If the number of stress cycles exceeds the stress cycle factor graph endpoint, the user has the option of using the graph end point or extrapolating the curve to lower values. ISO does not directly calculate an allowable power for a gear set, nor does AGMA calculate a service factor. The hardness in this example is the same on both parts ahma 58 RC so the same maximum afma bending stress applies, but often the pinion is harder than the gear.


Figure 5 is plotted for seven different gear sets at different power ratings. He is a registered Professional Engineer in the State of Texas. Currently, the basic gear tooth rating formulas are in AGMA It is necessary to iterate until the required safety factor is achieved. Ag,a Gap Width Inches 2 4 6 8 10 12 4 2. All are alloy steel.

Let us begin 60100 a brief description of these standards:. Beckman received a B. This standard is also available to be included in Standards Subscriptions. The rating methods and influences identified in this Standard are limited to enclosed drives of single and multiple stage designs where the pitch line velocities do not exceed feet per minute and pinion speeds do not exceed revolutions per minute. This agam is listed in paragraph 2. Be aware that the API service factors will probably be less than unity, but the comparison should indicate the most robust gear set.

Itinerary and Gear List. The results are very repeatable among manufacturers. AGMA, founded inhas developed rating standards by consensus using volunteers from the gear manufacturing companies and other interested parties who wish to participate.

Has some apex runout that produces additional loading. For more information, contact john.

Pitch dia, in Pinion 8. Frequently used for higher power applications for a given size, can transmit twice the power as BHN.

The designer has some limited choices when rating a long life gear set. It is calculated at the gear rated power. Limited thrust bearing loads and smaller 60100 bearings.

The added areas are: Need more than one copy? AGMA would allow the driver to have hp with a 1. The original standard contained formulas for computing the durability horsepower rating of gearing.

This would be comparable to the AGMA standard. This Standard does not apply to gear drives that are covered by other specific AGMA application standards.

Inthe rating formulas were changed to be identical with the API standard.
