The purpose of this document is to aid the gear designer in understanding the unique physical, mechanical and thermal behavior of plastic materials. The use of plastic materials for gear applications has grown considerably due to cost...
Due to their specification, design, and manufacture, plastic gears have unique issues that can affect the measurement methods and results obtained. This information sheet describes industry accepted practices to inspect molded plastic gears. It identifies the unique...
The actual power loss due to friction in a gear pair is of significant interest to the transmission community. This loss impacts fuel efficiency on almost every form of transportation. In aircraft applications, this loss converts to...
This standard provides tolerances for the tooth flanks of unassembled spur and helical gears. Tolerance classes are numbered from 1 to 11. Applicable definitions are provided. The purpose is to provide a common basis for specifying tolerances,...
This standard describes sizes and tolerances for straight and tapered bores and the associated keys and keyways, as furnished in flexible couplings. The data in the standard considers commercially standard coupling bores and keyways, not special coupling...
This standard specifies a method for rating the pitting resistance and bending strength of herringbone, double helical, and helical involute gear pairs as applied to metal rolling mills.
This document considers rating practices for marine main propulsion, power take-off and auxiliary propulsion service. Practical suggestions are included for various factors. Allowable stress numbers for materials of this standard, as covered in ANSI/AGMA 6033-C08, are included.
This standard includes design, lubrication, bearings, testing and rating for single and double helical external tooth, parallel shaft speed reducers or increasers. Units covered include those operating with at least one stage having a pitch line velocity...
This information sheet provides basic overviews of key approaches to establishing a condition monitoring and diagnostics program for open gearing and enclosed gear units.
The effect of the lubrication regime on gear performance has been recognized, qualitatively, for decades. Often the lubrication regime is characterized by the specific film thickness defined as the ratio of lubricant film thickness to the composite...
