This Standard Practice is intended for mud pump gearing only and should not be applied to any other type of oilfield equipment. It may be applied to mud pumps of any size and rating. It imposes certain stipulations from Standard AGMA 420.03, "Helical and Herringbone Gear...
This standard presents the fundamental formula for rating the surface durability (pitting) of helical and herringbone 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...
A gearmotor is defined as the combination of an enclosed gear drive and an electric motor with the frame of one component supporting the other, and with the motor shaft common with or directly coupled to the input pinion shaft. A gearmotor is further defined as any electro-mechanical..
This standard practice covers enclosed high speed helical and herringbone external tooth gear units of the parallel shaft type, and applies to all stages of stages if single or multiple stage gearing for speed increasing or speed reducing service. Units in this classification...
This standard is applicable to enclosed gear drives wherein the gear tooth designs include spur, helical, herringbone or double helical, or bevel, in single or multistage units. Limitations The rating methods and influences identified in this standard are limited to enclosed...
Scope and Responsibility This Standard Practice is limited to helical and herringbone enclosed speed reducers and increasers where pitch line velocities are less than 5000 feet per minute and pinion speeds are less than 3600 revolutions per minute. No limitations are placed on design or...

This standard practice covers spur, helical, herringbone, spiral bevel and combination spiral bevel helical or herringbone gear enclosed speed reducers and increasers with pitch line velocities not exceeding 5000 feet per minute and pinion speeds not exceeding 3600 revolutions...
The following factors are applicable to steel helical and herringbone gears used in commercial gearmotors. The gears and reducer components are to be manufactured within the conventional accuracy limits normally used by gearmotor manufacturers
The procedures in this Information Sheet describe the methods for determining Geometry Factors for Pitting Resistance, I, and Bending Strength, J. These values are then used in conjunction with the rating procedures described in AGMA 2001-B88, Fundamental Rating Factors and Calculation...
This Standard establishes a classification system which may be used to communicate geometrical quality specifications of unassembled external and internal involute gearing. It provides a designation system for quality, materials, and heat treatment of spur, helical (single or double), and...
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 and...
