Tables 1 Symbols and units 2. In Harmon Blok published his theory about the relationship between contact temperature and scuffing.

Causal Evidence from Equity Options. In addition, it added several improvements including: How to Use a Multimeter Jul 23, Effect of Concentration on Osmosis.

The effect of abma on numerical aberrations of spermatozoal chromosomes in testicular cancer patients. Effect of Structure on Acid-Base Properties. Manufacturers and end-users are encouraged, however, to ama with their lubricant suppliers to address specific concerns or special issues that may not be covered here such as greases. SCOPE This information sheet is designed to provide currently available tribological information pertaining to oil lubrication of industrial gears for power transmission applications.

Quantity must be a positive whole number. As specified in AGMAyou can use this input window to define the probability of scuffing and wear as well as susceptibility to micropitting frosting.


The probability of wear calculated by the standard is greater than the values that occur in practice.

Item Detail – AGMA A03 (reaffirmed January )

AGMA also includes a definition of the probability of scuffing. It is 925–a03 that this document serve as a general guideline and source of information about conventional lubricants, their properties, and their general tribological behavior in gear contacts. Accumulation of feedback data will serve to enhance future developments and improved methods to evaluate lubricant related wear risks.

Effect of Sweating on Insulation of Footwear. One of the key parameters is the estimated film thickness. Specifically, the subcommittee targeted the effect lubrication may have on gear surface distress. Effect of Binders on Ceramic Mould.

The information would also provide the user with more abma to help make a more informed decision about the performance of a geared system. Various methods of gear surfacedistressareincluded,suchasscuffingandwear,andinaddition,microandmacropitting. It is intended thatthis document serve as a general guideline and source of information about conventionallubricants, their properties, and their general tribological behavior in gear contacts.

Suggestions for improvement of this standard will be welcome. This should be considered a work in progress as more is learned about the theories and understanding of the various parameters and how they affect the life of the gear.


AGMA technical publications are subject to constant improvement,revision or withdrawal as dictated by experience. In particular, there is no reference to a scuffing load capacity specification as given in the FZG test. Thank you for visiting our website and your interest in our free products and services.

Asdiscussionsevolved,itbecame 925-0a3 that this should be a stand alone document which will hopefully serve manyothergeartypes.

Activity 7 – Effect of Environment on Plant Growth. There is therefore a tendency to underevaluate oils that have effective EP additives. Please download to get full document. Flow charts are included as aids to using the equations. However, defining the permitted scuffing temperature according to AGMA presents more of a problem, because of the lack of comprehensive or generally applicable information. Surface distress may be scuffing adhesive wearfatigue micropitting and macropittingor excessive abrasive wear scoring.

We are nonprofit website to share and download documents. You can therefore use this calculation method to optimize gear toothing for micropitting frosting.
