AGMA 6010-E88 – Standard for Spur, Helical, Herringbone, and Bevel…
Less efficient due to thrust bearing load. This is to evaluate the uneven loading across the length of the tooth. For double helical agmma sets, the calculation should include the gap. Subscription aga is determined by: The major difference is in the numbering system. They have evolved from standards originally published in It evolved from the DINPart 21standard, so there is a strong similarity between the two.
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 APIparagraph 2.

In this assignment, he is responsible in the preparation and auditing of specifications, equipment evaluation, engineering coordination, and testing and installation startup of rotating and special equipment. This standard includes design, rating, lubrication, testing and 60010 information for enclosed gear drives, including foot mounted, shaft mounted, screw conveyor drives and gearmotors.
Limited thrust bearing loads and smaller thrust bearings. Allows higher pitch line velocity because material has good stress relief property after heat-treatment. 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. agka
The ISO is recognized as being more complex and detailed that AGMArequiring about 20 more pieces of aga to calculate a gear set rating. As the voice of the U.
It is necessary to iterate until the required safety factor is achieved. In US customary units, Wt can be expressed as follows: It is beyond the scope of this Standard to present a detailed analysis of efficiency.
Item Detail – ANSI/AGMA E88 – NOTE: OBSOLETE STANDARD
Less tolerant to overload — sudden failure without warning. Shown in Table 1 is typical information on gap widths agmz a function of the normal diametral pitch Pnd: It is generally recognized that the DINPart 21standard is not suitable for through-hardened gear sets.
Spur gearing is also limited since it must be very large to transmit a load equivalent to the same size helical gear. The added areas are: Substituting into Equation 4: Your Alert Profile lists the documents that will be monitored. During testing, the test was stopped when pitting first appeared, which is not regarded as a failure point for through-hardened gearing.
You may delete a document from your Alert Profile at any time.
Teacher List Data Abma Specifications. Beckman received a B. The second edition atma the rating method to that given in API Higher efficiency due to smaller losses and lower lube oil requirements.
Calculate the Speed of the Robot Car. He previously served as a Design Engineer in high-speed gearing, and in he was promoted to Chief Engineer responsible for the engineering on all gears including low-speed through high-speed, marine, and repair. Gear Types Some of the most common gear types are: 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.
Figure 1 shows the pitting surface durability power rating and Figure 2 shows the 60100 strength ratings, with each line representing one gear set. Substituting into Equation 6 to solve for the pinion bending stress number: This could be appropriately compared to the AGMA standard.
For instance, some designs have many pinions in mesh with one gear.
Currently, the basic gear tooth rating formulas are in AGMA 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. Be aware that the API service factors will probably be less than unity, but the comparison should indicate the most robust gear set.
The allowable K factor is calculated as follows: It was released in Table 3 gives the resulting face width and center distance to meet the minimum service factor for that standard. There are committees currently working on revisions of APIintegrally geared air compressors, and APIcentrifugal compressors.
