Following is a brief history of the Standard: Special software designing for drawing of gear K. This standard is also 60110 to be included in Standards Subscriptions. The hardness in this example is the same on both parts at 58 RC so the same maximum allowable bending stress applies, but often the pinion is harder than the gear. Single Helical Agmx teeth of only one hand on each gear. This confusion is increased when comparing international and domestic standards.

Its gear tooth rating system refers to the formulas in the basic rating standard AGMA This standard is based on analyzing a gear set with mm centers, then modifying the results by a aga of factors such as size, speed, material, surface condition, and lubricant factors.

This standard is applicable in a single reduction gearbox if the pinion is over rpm or the gear tooth pitch line velocity is over fpm 35 mps. Both the speed and pitch line velocity overlap with the AGMA standard, so care must be taken to specify which standard prevails in the overlap situation.

Since college graduation he has been in gear engineering with Lufkin Industries. Bending Stress The bending stress value for both gear and pinion is a measure of gear tooth strength and is calculated per Equation 4 of API610 2. API 3rd Edition You can download and open this file to your own computer but Ag,a prevents opening this file on another computer, including a networked server.

To quote Annex G, paragraph G. In addition to confusing the purchaser and user, gear manufacturers are 601 P. The decrease in efficiency of 1. The gear sets used in this comparison are presented in Table 1, with changes between sets highlighted. At this revision, the formulas for the durability and strength horsepower rating were removed from the standard and were replaced by referring to the basic rating standard AGMA was the standard before the new numbering system.

It was released in This is a staggering difference. As the voice of the U.

These drives include spur, helical, herringbone, double helical, or bevel gearing in single or multistage arrangements, and wormgearing in multistage drives, as either parallel, concentric or right angle configurations. Lower pitch line velocity due to higher allowable unit loading. If the document is revised or amended, you will be notified by email. To reduce some of the confusion that a user 6100 have, it may be helpful to compare offers from different manufacturers by calculating and then comparing the API service factors.

This would be comparable to the AGMA standard. Complex heat treatment qgma. SCOPE This Standard is applicable to enclosed speed reducers and increasers wherein the gear tooth designs include spur, helical, herringbone or double helical, bevel, and their combination in multi – stage units.

The calculated AGMA service factor is 1. Speeds range from to 45, RPM.

API 5th edition The overlap exists when both the rpm are between and and the gear tooth pitch line velocity is between fpm 33 mps and fpm 35 mps. For a given gearbox, the rating system that is used can give very different answers in the amount of power that can be transmitted.

Shown in Table 1 is typical information on gap widths as a function of the normal diametral pitch Pnd: The generally accepted method for controlling this problem is to limit the shape of the pinion.

This will determine if the bidders are in compliance with applicable specifications and data sheets. For double helical gear sets, the calculation should include the gap. Gear manufacturers recognize that a more detailed analysis is important on high ratio gearing. Less thermal distortion due to shorter tooth. All gear tooth rating standards recognize that it is difficult to maintain equal loading across the width of the gear tooth.

Normal diametral pitch 5; Backlash 0.

AGMA would allow the driver to have hp with a 1. In a comparison with AGMAthe AGMA ratings were from 20 to 93 percent higher based on durability and 18 to 40 percent higher based on ag,a than the proposed method. The original standard contained formulas for computing the durability horsepower rating of gearing. The decision was appealed and is currently going through the AGMA appeal process. Let us begin with a brief description of these standards:
