1 Scope
This section provides a single involute cylindrical gear radial composite deviations and runout accuracy of the system. This section provides definitions tooth accuracy terms, the structure and precision gear system deviation allowable value. System radial measurement accuracy as compared with GB/T 10095.1 range of elements, there is a different level range. For radial composite deviations and Runout, diameter and its modulo range is different.
0.2mm to 10mm, diameters ranging from 5.0mm to 1000mm, see Chapters 6 and 7. Appendix A (informative Annex Record) given by the formula provided in Chapter 7 of the form.
b) Annex B (informative) gives definitions and runout accuracy for determining the rating of five runout, standard The body is not given. If the supply and demand sides of consensus, for ease of use, Appendix B provides a reference value runout area. 2 Normative references

5 related to radial composite deviations of tooth accuracy terms and definitions 5.1 Gear Products
"Product Gear" is how much of the gear to be measured or assessed.
5.2 radial composite deviation
Comprehensive measurements of radial deviation is affected by the overall degree of accuracy and product overlap gear measuring gear measuring gear (see GB /Z18620.2).
Total radial composite deviation in the radial direction (double-sided) integrated test, about the same time the gear tooth surfaces in contact with product measurement gear, and turned Center appears when a full circle from the difference between the maximum and minimum values. Figure 1 is an example of related graphics. Figure 1 radial composite deviation
A tooth radial composite deviations gear when the product is a full circle, the corresponding a pitch (360 °/z) of the radial composite deviation. product 5.5 Measurement Gear
When testing radial composite deviations, measuring gear should be engaged with the gear in the product, "effective length LAE" on. GB/T 10095.1 gives LAE definition.
For tolerance spur gear can be provided to determine its accuracy class. For helical gear due to longitudinal coincidence degree εβ will affect its radial composite measure Results amount of both supply and demand should be agreement to use, when used in the helical gear, the gear tooth width measurement should be made when the gear is engaged with the product εβ less than or equal to 0.5.
6 precision gear system configuration
According to this section of the radial composite deviation measurements determined accuracy level does not mean that the GB/T 10095.1 of the elements Deviation (such as pitch, tooth profile, helix, etc.) will be subject to the same level. When the file is described gear required accuracy requirements should be specified GB/T 10095.1 or GB/T 10095.2.
Radial composite deviation tolerance applies only to products and gear measuring gear meshing inspection does not apply to the two products meshed gears measuring.
6.1 Precision Gear
Accuracy class gear is carried by deviation between the measured and determined by the Chapter 7 numerical comparison later assessment. Calculated using the formula Value for Class 5 precision. Level between two adjacent interstage Sang common ratio equal to 2, the level value is multiplied (or divided) Sang 2 to get the next higher GB/T 10095.2-2008/ISO 1328-2.1997
High values (lower) level. No rounding the calculated value is multiplied by five precision 20.5 (Q-5), you can get any level of accuracy to be evaluated, the formula Q accuracy class is the number to be evaluated.
When the internal gear geometry is not the scope of the provisions in Chapter 1, the use of these formulas, both parties shall be by consensus. 6.2 Effectiveness of radial composite deviation
When the tolerance value is small, especially less than 5μm, measuring gear, including requirements include measuring instruments should be high enough precision to ensure Its value can be measured and the necessary repeatability.
You can press a predetermined tolerance level to determine the accuracy of the spur gear. Helical Gear, reference should be used in accordance with the agreement of both supply and demand, See 5.5.
7 radial composite deviation of five precision tolerance is calculated
The following formula, modulus and diameter of the actual values.
a) total radial composite deviation Fi "formula.
If there is no other agreement, you can use Chapter 6 Precision system criteria specified. Appendix A is a table of values according to A. Said about 2 The average value determined. Tolerance number of tables used only when both parties have an agreement. GB/T 10095.2-2008/ISO 1328-2.1997

A. 3 rounding rules
Tolerance values are according to the formula 6.1 and Chapter 7 of the calculated value after rounding obtained, if the calculated value is greater than 10μm, rounded to the closest The nearest whole number; if less than 10μm, 0.5μm rounded to the nearest decimal or integer. A. 4 Effectiveness
When in a given file, if the gear accuracy level required by the provisions of this standard a certain level, but not otherwise specified, Chapters 6 and 7 in all elements of bias refers to the accuracy level. However, according to the agreement, for any parameter when you use forms can be Specify different tolerances.

In the formula, use the method to the actual value of the modulus and diameter, and radial composite deviations, they are made with the same precision, see Section 6.1. B. 4 parameters
When applying the formula, the recommended upper and lower limits are as follows (Unit. mm). 5/20/50/125/280/560/1000...
