DIN 3968 Tolerances for Single-start Hobs for Involute Spur Gears
Deutsches Institut Fur Normung E.V. (German National Standard) / 01-Sep-1960 / 8 pages
ISO 1328-1:1995
Cylindrical gears -- ISO system of accuracy -- Part 1: Definitions and allowable values of deviations relevant to corresponding flanks of gear teeth
Cancels and replaces ISO 1328 (1975). Establishes a system of accuracy relevant to corresponding flanks of individual cylindrical involute gears. Specifies appropriate definitions for gear tooth accuracy terms, the structure of the gear accuracy system and the allowable values of pitch deviations, total profile deviations and total helix deviations. Applies only to each element of a toothed wheel taken individually. Does not cover gear pairs as such.

Cylindrical gears -- ISO system of accuracy -- Part 2: Definitions and allowable values of deviations relevant to radial composite deviations and runout information
ISO 6336-1:2006 Calculation of load capacity of spur and helical gears -- Part 1: Basic principles, introduction and general influence factors
ISO 6336-1:2006 presents the basic principles of, an introduction to, and the general influence factors for, the calculation of the load capacity of spur and helical gears. Together with ISO 6336-2, ISO 6336-3, ISO 6336-5 and ISO 6336-6, it provides a method by which different gear designs can be compared. It is not intended to assure the performance of assembled drive gear systems. It is not intended for use by the general engineering public. Instead, it is intended for use by the experienced gear designer who is capable of selecting reasonable values for the factors in these formulae based on knowledge of similar designs and awareness of the effects of the items discussed.
The formulae in ISO 6336 are intended to establish a uniformly acceptable method for calculating the pitting resistance and bending strength capacity of cylindrical gears with straight or helical involute teeth.
ISO 6336-2:2006 Calculation of load capacity of spur and helical gears -- Part 2: Calculation of surface durability (pitting)
ISO 6336-2:2006 specifies the fundamental formulas for use in the determination of the surface load capacity of cylindrical gears with involute external or internal teeth. It includes formulas for all influences on surface durability for which quantitative assessments can be made. It applies primarily to oil-lubricated transmissions, but can also be used to obtain approximate values for (slow-running) grease-lubricated transmissions, as long as sufficient lubricant is present in the mesh at all times.
ISO 6336-3:1996 Calculation of load capacity of spur and helical gears -- Part 3: Calculation of tooth bending strength
Gives the fundamental formulae for use in tooth bending strength calculations for involute internal and external gears with a minimum rim thickness under the root.
ISO 6336-5:2003 Calculation of load capacity of spur and helical gears -- Part 5: Strength and quality of materials
SO 6336-5:2003 describes contact and tooth-root stresses, and gives numerical values for both limit stress numbers. It specifies requirements for material quality and heat treatment and comments on their influences on both limit stress numbers. Values in accordance with it are suitable for use with the calculation procedures provided in ISO 6336-2 and ISO 6336-3 and in the application standards for industrial, high speed and marine gears. They are also suited to the calculation procedures given in ISO 10300 for rating the load capacity of bevel gears. It is applicable to all gearing, basic rack profiles, profile dimensions, design, etc., covered by those standards. The results are in good agreement with other methods for the range indicated in the scope of ISO 6336-1.
ISO 6336-6:2006 Calculation of load capacity of spur and helical gears -- Part 6: Calculation of service life under variable load
ISO 6336-6:2006 specifies the information and standardized conditions necessary for the calculation of the service life (or safety factors for a required life) of gears subject to variable loading. While the method is presented in the context of ISO 6336 and calculation of the load capacity of spur and helical gears, it is equally applicable to other types of gear stress.
