2、I/AGMA 6013-A06 Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, sub

3、stantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.

33、rved vi Foreword The 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 AGMA Standard 6013-B16, Standard for Industrial Enclosed Gear Drives. This standard revises, combines and supersedes two previous indep

34、endent standards, ANSI/AGMA 6009-A00, Standard for Gearmotors, Shaft Mounted and Screw Conveyor Drives, and ANSI/AGMA 6010-F97, Standard for Spur, Helical, Herringbone and Bevel Enclosed Drives. The history of these standards have their roots in: - AGMA 420.04, Practice for Enclosed Speed Reducers o

35、r Increasers Using Spur, Helical, Herringbone and Spiral Bevel Gears - AGMA 460.05, Practice for Gearmotors Using Spur, Helical, Herringbone and Spiral Bevel Gears - AGMA 480.06, Practice for Spur, Helical and Herringbone Gear Shaft-Mounted Speed Reducers ANSI/AGMA 6013-A06 presents general guidelin

36、es and practices for design, rating and lubrication of parallel, concentric, and right angle shaft drives. It includes foot mounted, shaft mounted, screw conveyor drives, and gearmotors. It includes the available data, gear technology, and operational experience. The comprehensive thermal rating pro

37、cedure has been removed but is included by reference to AGMA ISO 14179-1. This standard reflects the consolidation of “Enclosed Drives”, to include gearmotors, shaft mounted, and screw conveyor drives, into a single document. The allowable stress numbers used in this standard are derived from ANSI/A

38、GMA 2001-D04, Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth and ANSI/AGMA 2003-C10, Rating the Pitting Resistance - expanded crane service factor recommendations; - revised and updated lubrication clause. The competence to design enclosed gear drives, es

39、pecially the knowledge and judgment required to properly evaluate the various rating factors, comes primarily from years of experience in designing, testing, manufacturing, and operating similar gear drives. The proper application of the general rating formulas for enclosed gear drives is best accom

40、plished by those experienced in the field. The first draft of ANSI/AGMA 6013-A06 was created in November 2000. It was approved by the AGMA membership in March 2006. It was approved as an American National Standard on April 25, 2006. The first draft of ANSI/AGMA 6013-B16 was created in November 2011.

44、reased external load capacity. 4.1 Momentary load Gear drives designed and selected in accordance with this standard permit the following peak load conditions: - each peak shall not exceed 200% of the unit rating (at a service factor or application classification I, KSF = 1.0); - a limited number of

45、 peak stress cycles, typically less than 104. AMERICAN NATIONAL STANDARD ANSI/AGMA 6013-B16 AGMA 2016 All rights reserved 4 For applications exceeding these conditions an appropriate service factor, or application classification, should be selected. WARNING: For momentary torques in excess of 200%,

46、stall conditions, and low number of stress cycles the gear drive should be evaluated to confirm that these conditions do not exceed the yield strength of any component. Some applications may require selecting a gear drive with increased unit rating in order to accommodate adverse effects of environm

47、ental conditions, thermal capacity of the unit, external loading, or any combination of these factors. 4.2 Rating factors For calculating pitting resistance and bending strength rating for gears, specific values or procedures for rating factors are given in Clause 6. Material properties, manufacturi

48、ng considerations, or experience may indicate that more, or less, conservative rating factors may be used. 4.3 System analysis This standard assumes that within the operating speed range, the system of connected rotating parts is compatible and free from critical speeds and torsional, or other types

49、, of vibration, no matter how induced. The gear drive designer or manufacturer is not responsible for the system analysis. 4.4 Considerations for cold temperature operation If units are to be operated in cold temperatures, generally below 32F, care should be taken to select materials and components that have adequate properties at the operating temperature. Consideration should be given to: - low temperature impact strength of materials; - fracture appearance transition or nil ductili
