AGMA 920 - MATERIALS FOR PLASTIC GEARS Organization: AGMA
Date: 2015-01-01
Description: Only a limited number of plastic materials are mentioned here as commonly used for gears. Gears have been made from other plastics as well, but generally because some special material property or commercial consideration was judged essential to a particular application.
AGMA 909 - SPECIFICATIONS FOR MOLDED PLASTIC GEARS Organization: AGMA
Date: 2006-07-18
Description: The objective of this information sheet is to inform the plastic gear designer of the importance to clearly and thoroughly define the gear specifications to the plastic gear producer.
AGMA 1106 - TOOTH PROPORTIONS FOR PLASTIC GEARS Organization: AGMA
Date: 1997-08-07
Description: Presents a new basic rack, AGMA PT, which, with its full round fillet, may be preferred in many applications of gears made from plastic materials. It contains a description, with equations and sample calculations, of how the proportions of a spur or helical gear may be derived from the design tooth thickness and the basic rack data.

Date: 1997-08-07
Description: Presents a new basic rack, AGMA PT, which, with its full round fillet, may be preferred in many applications of gears made from plastic materials. It contains a description, with equations and sample calculations, of how the proportions of a spur or helical gear may be derived from the design tooth thickness and the basic rack data.
AGMA 07FTM01 - ESTIMATION OF LIFETIME FOR PLASTIC GEARS Organization: AGMA
Date: 2007-10-01
Description: As no secure data for plastic gears is available, how can nevertheless plastic gear design and life time prediction be improved?
AGMA 08FTM01 - PARAMETRIC STUDY OF THE FAILURE OF PLASTIC GEARS Organization: AGMA
Date: 2008-10-01
Description: This paper presents the results of collaboration to develop tools for the prediction of plastic gear tooth failure for any given set of operating conditions and to classify failure modes of these gears. The goal of the project is to characterize and predict the failure of plastic gears over a range of given parameters.
AGMA 97FTM4 - MEASUREMENT AND PREDICTIONS OF PLASTIC GEAR TRANSMISSION ERRORS WITH COMPARISIONS TO THE MEASURED NOISE OF PLASTIC AND STEEL GEARS Organization: AGMA
Date: 1997-11-01
Description: Many studies have been done in the area of plastic gearing such as plastic material selection, injection molding and load capacity of plastic gears. Severai historical papers imply that plastic gears are "quieter" than steel gears.
AGMA 07FTM04 - APPLYING ELEMENTAL GEAR MEASUREMENT TO MOLD MODIFICATION OF MOLDED PLASTIC GEARS Organization: AGMA
Date: 2007-10-01
Description: Although elemental gear inspection is rarely specified for molded plastic gears, themeasurement equipment and practices can be valuable in advancing the molding processes and improving the quality of the molded gears.
AGMA 91FTM14 - THE EFFECT OF THERMAL SHRINK AND EXPANSION ON PLASTIC GEAR GEOMETRY Organization: AGMA
Date: 1991-10-01
Description: When plastic gears are meshed with steel gears there can be the differences in thermal expansion between the two materials.
AGMA 07FTM03 - MATERIAL INTEGRITY IN MOLDED PLASTIC GEARS AND ITS DEPENDENCE ON MOLDING PRACTICES Organization: AGMA
Date: 2007-10-01
Description: The quality of molded plastic gears is typically judged by dimensional feature measurements only. This practice overlooks potential deficiencies in the plastic injection molding process and its effect on the integrity of the plastic material.
AGMA 06FTM03 - DETAILED PROCEDURE FOR THE OPTIMUM DESIGN OF AN EPICYCLIC TRANSMISSION USING PLASTIC GEARS Organization: AGMA
Date: 2006-10-01
Description: The design was developed using the tooth proportions proposed in ANSI/AGMA 1006-A97, Tooth Proportions for Plastic Gears and taking into account the recommendations given in AGMA 6023-A88, Design Manual for Enclosed Epicyclic Gear Drives and ANSI/AGMA 2101-C95, Fundamental Rating Factors and CalculationMethods for Involute Spur and Helical Gears taking into account the effect of changing the number of planets, the bending fatigue and contact strength of the plastic materials, and the temperature effects on the size of the gears.
AGMA PLASTIC GEAR SET - AGMA PLASTIC GEAR SET Organization: AGMA
NAVISTAR TMS 7089 - PLASTIC GEARS - SPEEDOMOTER Organization: NAVISTAR
AGMA 92FTM11 - NEW FINDINGS ON THE LOADING OF PLASTIC SPUR GEAR TEETH Organization: AGMA
Date: 1992-10-01
Description: Explains how CAD software and plastic gear calculating software can simulate the kinematics of a gear pair to predict and localize interference on the back of the tooth.
AGMA 05FTM01 - FINE PITCH, PLASTIC FACE GEARS: DESIGN AND MANUFACTURE Organization: AGMA
Date: 2005-10-01
Description: Products benefiting include those which use molded plastic gears. More applications could benefit, justifying the need formore information on the special features of face gears, their design and manufacture, in comparison to other non--parallel--shaft gears.
NAVISTAR - TMS 7089 - RESTRICTED ISSUE - PLASTIC GEARS - SPEEDOMETER - REVISION B-1 Organization: NAVISTAR
Date: 2001-08-01
