Presents the necessity of comparing ISO and AGMA power rating standards. Gives the results of using computer software to compare the behavior of the bending geometry factor (J-factor) values for 135 spur-gear meshes. Shows that differences exist between the results given by ISO...
The risk of gear tooth scuffing in commercial vehicle transmissions has gained more attention because of increasing demand for fuel-efficient powertrain systems in which diesel engines run at lower speeds, power density is higher, and lubricants are modified to improve efficiency and...
This standard presents the fundamental formula for rating the surface durability (pitting) of spur gear teeth. It contains all of the factors which are known to affect the resistance of gear teeth to pitting. This formula is not applicable to other types of gear tooth...
This standard applies to spur and helical gearlng of 20 through 120 diametral pitch. Similar data for spur gears of 19.99 diametral pitch and coarser is found in USAS B6.1-1968, "Tooth Proportions for Coarse-Pitch Involute Spur Gears." (AGMA 201.02). The...
The prediction of bending stresses in a gear tooth, resulting fxom an externally applied torque, requires special consideration when designing spur gear systems. The tooth geometry is such that excess risers exist which must be accounted for. In addition, variables affecting...
Introduction Measurements over pins on involute spur gears are taken to determine the tooth thickness of a gear-one way, possibly the most accurate way, to determine tooth thickness. There are other methods which use calipers, special micrometers, gear measuring blocks...
This standard applies to spur and helical gearing of 20 through 120 diametral pitch and coarser is found in ANSI B6.1-1968, "Tooth Proportions for Coarse-Pitch In volute Spur Gears."(AGMA 201.02). The tooth proportions shown herein will be suitable for many...
