For single helical gear sets, the calculation is 600 based on the shorter of the pinion or the gear tooth length, if they are different. For instance, some designs have many pinions in mesh with one gear. This standard is also available to be included in Standards Subscriptions.

600 It is generally recognized that the DINPart 21standard is not suitable for through-hardened gear sets. Figure 5 is plotted for seven different gear sets at different power ratings.

The information on the API data sheet is as follows: Limited thrust bearing loads and smaller thrust bearings. The gap is usually required because of the manufacturing process, therefore the gap can change slightly depending on the type of process used.

Spur gearing is also limited since it must be very large to transmit a load equivalent to the same size helical gear.

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 would be comparable to the AGMA standard. The decision was appealed and is currently going through the AGMA appeal process. The first high-speed gear unit standard qgma adopted in and has evolved over time. Your Alert Profile lists the documents that will be monitored.

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

If you specify this standard, you will probably pay substantially more for the gearbox than if another standard is used. This could be appropriately compared to the AGMA standard. Subscription pricing is determined by: The durability rating is about the same for through-hardened gear sets, but ISO has higher durability ratings for carburized gear sets. The following are the major technical areas that require detailed review prior to the selection of the specific gear design and its suppliers.

It is not intended for use by the engineering public at large.

Comparisons with API have resulted in virtually the same durability ratings, but different strength ratings. It is primarily intended for gears that are in continuous service without installed spare equipment. The allowable K factor is calculated as follows: The majority of heavy industrial gears are of single or double helical gear design.

There are committees currently working on revisions of APIintegrally geared air compressors, and APIcentrifugal compressors.

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. Because some of the afma are load dependent, it is not possible to calculate the capacity of the gear set unless the load is known, unlike the AGMA standard.

AGMA would allow the gas turbine to have 26, hp when using the agam 1. Gear manufacturers recognize that a more detailed analysis is important on high ratio gearing.

The calculated AGMA service factor is 1. 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.

The motor is nameplated at hp, 1. One direction of rotation. Fortunately, the overlap is small. The material index number is based on the hardness and the heattreating process.

The Standard is obviously derived from APIto the extent that the layout, figures, testing, and data sheets are easily recognized. The added areas are: Number of teeth Pinion 38; Gear Page 1, line
