Item Detail – ANSI/AGMA E88 – NOTE: OBSOLETE STANDARD

The added areas are: However, it does incorporate language to allow the use of alternate rating methods if the API method would result in excessive pitch line velocity or excessive face width. For double helical gear sets, the calculation should include the gap. An example of a gearbox fitting into this overlap is an hp, rpm electric motor driving through a speed increasing gearbox to a rpm centrifugal compressor.

In addition to confusing the purchaser and user, gear manufacturers are Vinod P. There are committees currently working on revisions of APIintegrally geared air compressors, and APIcentrifugal compressors. As the voice of the U. Casing Fabrication Cast casings are more commonly used due to their lower cost and shorter delivery time, and to comply with low noise requirements.

Lower pitch line velocity due to higher allowable unit loading.

Gearbox specs: Getting it right | Turbomachinery Magazine

The gear set is carburized and has a Lower efficiency due to larger losses. The original standard contained formulas for computing the agka horsepower rating of gearing.

Standard for 6001 Enclosed Gear Drives. This standard, which is composed of five separate parts, is largely based on prior DIN German Standards Institute standards, and is generally accepted everywhere outside of the U. Substituting into Equation 6 to solve for the pinion bending stress number: Problems have been recognized with AGMAso it will be revised or withdrawn.

The gear tooth rating of this standard seems to reasonably repeat when the same gear set is compared among different gearbox manufacturers.

The voting terminates on July 3, The allowable K factor gama defined as follows: This is a staggering difference. Documents Flashcards Grammar checker. It will vary slightly among manufacturers depending on the shape of the roughing and finishing tool as well as heat-treating distortion.

Standards Subsctiption may be the perfect solution. The material index number is based on the hardness and the heattreating process.

Pitch dia, in Pinion 8. Gear manufacturers recognize that a more detailed analysis is important on high ratio gearing. Currently, the basic gear tooth rating formulas are in AGMA Requires thrust bearings and thrust faces on each rotor. It is necessary to iterate until the required safety factor is achieved. It is limited to gearboxes with gear tooth pitch line velocities below 12, fpm 60 mps for parallel shafts or fpm 40 mps for bevel shafts.

This comparison is based on an rpm motor driving through a speed increasing gearbox to a centrifugal compressor at rpm. The size and therefore the price of a gearbox depend on the gear-rating method specified. Special software designing for drawing of gear K. Method A often includes full size testing as would be appropriate in the aerospace industry. The first high-speed gear unit standard was adopted in and has evolved over time. An even wider range of gears could have been analyzed, but that probably would not significantly change the general conclusions of this study.

This guideline is listed in paragraph 2. This standard is also available to be included in Standards Subscriptions.

The allowable bending stress number depends on materials selected for the gear teeth, the tooth hardening processes used, and the service factor. Already Subscribed to this document. The API committee is reviewing a proposal to change the method of rating the gear sets with a ratio greater than 7. This confusion is increased when comparing international and domestic standards.

Table 3 also gives the AGMA service factor for each gear set so that the robustness and cost can be sgma.
