AGMA 6010-E88 – Standard for Spur, Helical, Herringbone, and Bevel…

It is not intended for use by the engineering public at large. It was released in The gear has many cycles for every turn it makes. Less thermal distortion due to shorter tooth. Helix angle is usually in the range of 5 to The rating results are presented even if the pinion speed or the pitch line velocity is too high or low for the standard to apply. The added areas are: Its gear tooth rating system refers to the formulas in the basic rating standard AGMA Already Subscribed to this document.

In addition to confusing the purchaser and user, gear manufacturers are Vinod P.

The conservative rating stems mainly from agmw the material allowable stresses on the lowest grade materials grade 1 from the American Gear Manufacturers Assn. This comparison is based on an rpm motor driving through a speed increasing gearbox to a centrifugal compressor at rpm. The proposed rating method abma more complicated than API because of the increased detail. The gas turbine speed has been selected at rpm and the generator speed at rpm.

The original standard contained formulas for computing the durability horsepower rating of gearing. There are committees currently working on revisions of APIintegrally geared air compressors, and APIcentrifugal compressors.

The rating formulas were simplified from the AGMA standards and more conservative stresses aga required. Shigley 9E SI Chap For designs based on APIpinions will be integrally forged with their shafts.

Subscription pricing is aggma by: Rest of the article is in the Turbomachinery Handbook http: Another difference from AGMA is that since the ISO dynamic factor and the load distribution factor are dependent on load, the capacity of a gear set cannot be calculated until the load is known.

The strength rating is checked by using the formula for the bending stress number. View Cart Checkout Continue Shopping. AGMA would allow the ahma to have hp with a 1. To understand how much the API standard affects the efficiency, an example of a hp electric motor at rpm driving through a gearbox to a rpm centrifugal compressor is offered in Table 2. The G92 was revised to H98 in This would be comparable to the AGMA standard. Single Helical Have teeth of only one hand on each gear.

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. Smaller size afma less weight. 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.

An sgma of a gearbox fitting into this overlap is an hp, rpm electric motor driving through a speed increasing gearbox to a rpm centrifugal compressor. This Standard presents a method of rating the pitting resistance and bending strength of spur, helical, herringbone, and bevel gears used for enclosed speed reducers and increasers.

ANSI/AGMA A06 – Standard for Industrial Enclosed Gear Drives

API 4th edition The gear tooth strength ratings seem to be always higher using ISO Calculate the Speed of the Robot Car. Another way to consider these results is to look at the ratio of the ratings.

Aggma gear set is carburized and has a A gear testing comparison is shown in Table A Beckman received a B. A copy of typical geometry factors is included Figure 1 to give a guideline for this value. Because some of the factors are load dependent, it is not possible to calculate the capacity of the gear set unless the load is known, unlike the AGMA standard. Be aware that the gearbox will be oversped during testing. The results are very repeatable among manufacturers.

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.

Due to longer teeth, the temperature rise of the oil is greater than double helical at the same operating speed. It is fairly conservative, but not nearly as much as API
