19、ut license from IHS -,-,- ANSIIAGMA 6110-F97 AMERICAN NATIONAL STANDARD Foreword r h e foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of ANWAGMA Standard 61 10-F97, Standard for Spur, Helical, Herringbone a
20、nd Bevel Enclosed Drives. This standard presents general guidelines and practices for design, rating (including catalog rating) and lubrication of enclosed gear drives and is a revision to and supersedes ANSI/AGMA 601 0-E88, Standard for Spur, Helical, Herringbone and Bevel Enclosed Drives. This sta
21、ndard was revised to include the latest data available using current gear technology and includes operational experience. Also, this revision conforms to the American Gear Manufacturers Association style manual. This standard is written in hard metric while the parallel standard, AN SI/AGMA 601 O-F9
22、7, is available in conventional units. The allowable stress numbers used in this standard are derived from ANWAGMA 21 O 1 -C95 and ANWAGMA 2003-A86 and along with other rating factors, provide a rating basis for enclosed gear reducers and increasers. The rating formulas are based on many years of ex
23、perience in the design and application of enclosed gear drives for industrial use. The allowable stress numbers used by this standard are adjusted by the factors ZN and YN for the required number of cycles of operation. In previous versions of this standard, a CL and .ki value of unity has been allo
24、wed. Deviations from ANWAGMA 2101 -C95 or AN WAGMA 2003486 are not recommended unless they can be justified. The use of the stress cycle adjustment factor does not guarantee that a certain number of hours or revolutions of life will be obtained, but i s a method of approximating gear life under diff
25、erent load and speed conditions. The most significant changes in this standard include: information on obtaining ratings by direct reference to the empirical methods in ANWAGMA 2101-C95 and ANWAGMA 2003486; references to the necessary additional standards; a uniform selection method by specifying a
26、nominal L 1 life for the gearing of 10 W O hours; and a refinement of the thermal rating practice. The competence to design enclosed gear drives, especially the knowledge and judgment required to properly evaluate the various rating factors, comes primarily from years of experience in designing, tes
27、ting, manufacturing and operating similar gear drives. The proper application of the general rating formulas for enclosed gear drives is best accomplished by those experienced in the field. There is a need for a thorough knowledge and use of the safety, service and application factors. Application f
28、actors will represent actual loadings or will be replaced by a load spectrum analysis such as Miners Rule. Work was started on this draft in Decemberl991. This version was approved by the AGMA membership in June 1997. It was approved as an American National Standard on September 16, 1997. Suggestion
29、s for improvement of this standard will be welcome.

37、, stall conditions and low number of stress cycles, the gear drive should be evaluated to assure the user of this standard that these conditions do not exceed the yield strength of any component. Some applications may require selecting a gear drwe with increased mechanical rating in order to accommo
38、date adverse effects of environmental conditions, thermal capacity of the unit, external loading or any combination of these factors such as overhung, transverse and thrust loads. 3.2 Rating factors The allowable stress numbers taken from ANSI/ AGMA 2101 -C95 and ANSVAGMA 2003486 are maximum allowed
39、 values. Some latitude based upon experience is permissible in the selection of specific factors within this standard. Less conserva- tive values for rating factors in this standard shall not be used. Ratings shall be as outlined in clauses 4 and 5. 3.3 Cold temperature operation If units are to be
40、operated below -30“ Cl care must be given to select materials which have adequate impact properties at the operating temperature. Consideration should be given to: low temperature impact strength specifica- fracture appearance transition or nil ductility reduce carbon content to less than 0.4 per- u
41、se of higher nickel alloy steels; - tion; - temperature specification for impact testing; - cent; - - lubricant problems. 3.4 System analysis The system of connected rotating parts must be compatible, free from critical speeds, torsional or other types of vibration, within the specified operat- ing
42、speed range no matter how induced. The enclosed gear drive designer or manufacturer is not responsible for this analysis, unless agreed to in the purchase contract. 4 Unit rating Historically, many terms have been used to denote conditions of operations - both calculated and actual. These terms have
43、 resulted in confusion as to the actual capability of the enclosed drive. Examples of terms previously used to denote some form of enclosed drive capacity are listed below: - service rating; - nameplate rating; - equivalent rating; - catalog rating; - mechanical rating; - brake rating; - unrtyrating
44、; - transmitted power; - calculated power; - allowable power; - application power. For purposes of this standard, where component capacities are being determined, the calculations are specifically related to the unit rating as defined below. 4.1 Unit rating definition The unit rating is the overall
45、mechanical power rating of all static and rotating elements within the enclosed drive. The minimum rated component (weakest link, whether determined by gear teeth, shats, bolting, housing, etc.) of the enclosed drive determines the unit rating. 4.2 Unit rating requirements The unit rating implies th
46、at all items within the gear drive have been designed to meet or exceed the unit rating. Gear and pinion ratings are to be in accordance with the bending strength and pitting resistance ratings as outlined in this standard. Shaft stresses, key stresses and fastener stresses are to be within the limi
47、ts set by this standard. Rolling element bearing or sleeve bearing designs are to be within limits set by ANWAGMA 6001 -D97. Where user requirements or specifications dictate different design criteria, such as higher bearing life, this must be by contractual agreement. Unit ratings may also include
48、allowable overhung load values which are usually designated to act at a distance of one shaft diameter from the face of the housing or enclosure component. Stresses in related parts resulting from these overhung loads must also be within limits set by this standard. Refer to clause 7 for further inf
49、ormation. 5 STDOAGMA bLLU-F77-ENGL 1777 I b87575 Oc105781 798 Copyright American Gear Manufacturers Association Provided by IHS under license with AGMA Licensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 04/18/2007 03:50:59 MDTNo reproduction or networking permitted without license from IHS -,-
