It occurs when the oil film thickness is small enough to allow the flanks of the gear teeth to contact 4. Type B indicates only hardening of flanks extending to the form diameter. Gear blank design is beyond the Km is load distribution factor see clause15 ; scope of this standard see 5. Editorial corrections were 2001-s04 to table 8, figure 14 and table E, and style was updated to latest standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard.
Editorial corrections were implemented to table 8, figure 14 and table E-1, and style was updated to latest standards. Equations 28 and 29 are used to establish power ratings for unity service factor to which established service factors may be applied using equation Ideally, a gear set would have a at which the driven agmz will perform.
AGMA duced amga a process 20011-d04 than generating. Corrosion of the gear tooth surface can have a 3. The pinion and the gear. Other special where the specified mechanical properties hard- stock allowances such as those used to minimize dis- ness are required.
The allowable stresses are only valid for materials 3. The effective case depth for induction and flame Unless the appropriate gear quality level stress levels. The effect of this undercut is to move the highest point of single 2001-v04 contact, negating the assumption of this calculation method.

When this is done, the stress cycle factor is 9 Overload factor, Ko calculated using the number of cycles equivalent to a specific number of hours at a specific speed, to The overload factor is intended to make allowance establish power rating for unity service factor.
The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. Exceptions The formulas of this standard are not applicable to other types of gear tooth deterioration such as plastic yielding, wear, case crushing and welding.
The effect of this under- mance of assembled gear drive systems. Cmf and Cmt can be interrelated depending on the For helical gears having two or less axial overlaps, form of the instantaneous contact line in the plane of the interaction of lead and profile effects are so action as shown by figure 4. Other UT specifications which ensure the same quality level are permitted. The amount of non–uniformity of the load distribution is caused by, — Gear ratio; and is dependent upon, the following influences: Boeing Commercial Airplane Group J.
The major factors which affect gear tooth pitting and gear J factor calculation uses the stress correction fac- tooth fracture at the fillet radius. Also see AGMA the following approximate method may be used: Sulfur content Not specified 0. A distance amplitude correction curve is not in tended. Cognis Corporation — Lubricant Technologies C. Clearly, however, the people with the most pressing interest in our industry are our customers, the end users of gear products.
Gear blanks may have natural frequencies within the operating speed range. This is especially true in the truck market, where engines are quieter because they run at lower speeds to improve fuel economy, but they quite often run at high torsional vibration levels.
I is geometry factor for pitting resistance see clause 6 ; — The compressive stress at tooth roots caused d is operating pitch diameter of pinion, in. SCOPE Rating formulas This standard provides a method by which different gear designs can be theoretically rated and compared.

Philadelphia Gear Corporation W. The formulas presented in this standard contain factors whose values vary significantly depending on application, system effects, gear accuracy, manufacturing practice, and definition of gear failure. It is now greater than 1.
