Profile method — Rules and procedures for the assessment of surface texture ISOCalculation of load capacity of spur and helical gears — Part 2: The procedures in ISO provide rating formulae for the calculation of load capacity, based on pitting and tooth root breakage.
If this limit is exceeded, it is recommended to check the selected material in proportion to the gearing load. Definitions related to geometry ISO ISO is designed to facilitate the application of future knowledge and developments, also the exchange of information gained from experience.
This is a standard gearing calculation, where the rack ido in gear with the pinion. Eh, IF, NT nitr. The most frequent way includes the serial arrangement, where the total transmission ratio efficiency is determined by the product of partial transmission ratios efficiency.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

Profile method — 636-2, definitions and surface texture parameters ISO Enter the email address you signed up with and we’ll email you a reset link.
Search all products by. Since it has no meaning to correct the gear rack 6336-2 this case, only the pinion correction is possible axial distance, gear condition and strength parameter improvement. Pinion and wheel parameters: For the proposal of the tensile strength Rm and yield strength Isp.
For undated references, the latest edition of the referenced document including any amendments applies. In the unlikely event that a problem relating to it is found, please inform the Central Iwo at the address given below. K 1 Accuracy grades as speclfled in ISO Click to learn more. This part of ISO describes contact and tooth-root stresses, and gives numerical values for both limit stress numbers. Parameters for the time-strength curves were obtained from ISO and 3.
You can see an example of a simple planetary gearing with 6336-22 toothing of the planet below. Help Center Find new research papers in: Main resonance of gear with idler gears, inner gears and planet gears are calculated by different process.
The planets are 636-2 gearwheels mounted in a pivoting way on the carrier and they mesh with the suns or with each other. Determination of normal chordal dimensions of tooth root critical section for Method B A The manufacturing tool profile can be specified both for the pinion and the gear rack.
It is possible to use several methods isk, measurement, estimation. Operating pitch diameter MK It is possible to select the number the pinion teeth, the pressure angle and the tooth 636-2. The rating formulae 63362- ISO are not applicable to other types of gear tooth deterioration such as plastic yielding, scuffing, case crushing, welding and wear, and are not applicable under vibratory conditions where there may be an unpredictable profile breakdown.
Included in the formulae are the major factors which are presently known to affect gear tooth pitting and fractures at the root fillet. This part of ISO specifies the fundamental formulae for use in the determination of the surface load capacity of cylindrical gears with involute external or internal teeth.
This equation is valid for the range 1.
BS ISO 6336-2:2006
These data were used in the calculations below. Instead, it is intended for use by the experienced gear designer who is capable of This is a free 10 page sample. There are three calculation methods BC a C The values of Ro, E and Poisson constant are lso available. As 6336–2 planet and the ring gear have the same axis, the centre distance between the planet and both suns must be the same.

The loss output can be determined from the relation: With respect to the above-specified advantages, the use of planetary gearings is popular in a wide range of applications e.
After securing function requirements, it is possible to further optimize corrections in order to improve one or more important toothing parameters.
In the formulas, indexes 1 and 2 are used for a pinion and a wheel which is a pair: Calculation of load capacity of spur and helical gears. In order to provide proper functioning, the following several conditions must be followed and observed. For dated references, only the edition cited applies.
For other optimizing processes there is a wide range of recommendations in professional literature, namely the so-called diagrams charts of limit corrections, providing lso clear view of possibilities and selection of corrections.
ISO does not apply to teeth finished by forging or sintering. Basic principles, introduction and general influence factors 1 Scope This part of ISO 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.
