ISO Foreword
19 (The International Organization for Standardization is a world-wide union of international standardization bodies (ISO member bodies): The work of formulating international standards is usually completed by the technical committees of ISO. If the member is interested in the standard item that the committee has formulated, they will participate in the work of the committee. International organizations (particularly or non-partisan) that maintain contact with ISO can participate in related work. In the field of electrotechnical standardization, ISO maintains close cooperation with the International Electrotechnical Commission (IEC). The main task of the technical committee is to formulate international standards - but under special circumstances, the technical committee can propose changes. A Technical Report (TR) of one of the following types is published: - Type 1: when the technical work is still under development or, for various reasons, may only be agreed to become an International Standard in the future rather than at present; - Type 3: when a technical person collects information that is different from the International Standard being published (for example, the current state of the art). Technical reports of types 1 and 2 should be reviewed within three years of publication to determine whether they can be converted into International Standards. Type 3 is a Technical Report Convex, does not necessarily need to be reviewed, until the information provided is no longer considered useful or valid. ISO)/TR10064-1 is a technical report of the third type. It is prepared by the ISO/[:6) Gear Technical Committee. This report provides instructions and recommendations for the implementation of gear inspection. ISO, TR100G4 includes the following parts under the general title "Specification for the implementation of round gear inspection": - Part 1: Inspection of gear teeth; - Part 2: Inspection of radial runout and tooth thickness. ISO introduces the international standard 1S01326:1S75, which includes the definition and requirements of gear tolerances, and also provides relevant test methods. The discussion of the nature of the matter,
In the process of ordering 19015:1975, the gear gun force method has always been the report and production of the surface, the effect is high to the modern technical level, due to the increase in content to improve other considerations, the decision will be related to the implementation as a fifth type of technical report, the kitchen issued, ten bases, together with this technical announcement to formulate the second fourth standard series document 1

The tooth drum is on the reference plane (base plane 1). The effective length of the tooth rate is the length of the circle at the starting point of the ineffective rate. The tooth bucket is the circle length of the tooth rotation end value. The wavelength of the line (in the direction of rotation) is the wave attenuation caused by the axial direction of the load. The new end is used as the reference plane. The inspection of various gear tooth elements requires a variety of operations. First of all, it must be ensured that in all measurements, such as when the gear is rotating, the actual working line of the gear should be consistent with the measurement process. During the annual inspection, it is not economical to measure all the important adjustments such as the pitch of the individual wheels, the pitch of the parts, the direction of the thread, the running direction, the speed of the moving surface, etc. Because the variable speed has no obvious effect on the age of the fixed gear, some measurements can be replaced by some daily ones. For example, the average gear pitch value difference can be reduced by the comprehensive deviation between the gears at the beginning of the gear life. After comprehensive inspection, the runout inspection can replace the runout inspection: For such situations, the special plan ISO/1R10063 can be used to infer the thickness of the gear working life, and the inspection groups and tolerance families can be inferred according to the working gear working life. Of course, it should be emphasized that for the slightest quality control measurements, they must be determined by the purchasing process and the supplier. 5 Identification of the position of the tooth
When measuring a gear tooth, a convenient way to identify the error is to specify the position involved, such as right tooth surface, left tooth surface, pitch or their combination.
5.1 Right or left tooth surface
For a given gear, one of the reference surfaces is the "right tooth surface" and the other non-reference surface is the "[". When observing the reference surface, the right tooth surface is on the left and the left tooth surface is on the left! 01.2), the right and left teeth are represented by the letter "R\".
30R=30th step right
21.-2nd, left tooth
1-1, left tooth surface
30R-30th tooth pitch, right tooth surface
Figure 2 Marking and numbering of internal gears
5.2 Right or left of helical gear
The force direction of external or internal gears is indicated by right or left, and the direction of threading is indicated by the letter "": When the tooth grid is erected in front of the observation, the tooth measured to the right (left) and above is the (left) tooth. 5.3 Abbreviation of teeth and tooth surface
If the gear is not aligned, the number of teeth is increased by the time needle: the letter R or I+ after the tooth number indicates right or left, such as "2L".
5.4 The number of the tooth
The number of a single tooth is related to the number of the next tooth. The Vth tooth is between the "V-1" tooth and the "\th tooth". The number K is 1. It indicates whether the tooth is the right tooth or the left tooth. For example, "tooth surface" (see Figure 1) 5.5 Pitch number\&\
The subscript \\ of the deviation symbol indicates the number of adjacent teeth to be measured. In practice, the number is often replaced by, such as F, which indicates the product deviation of the teeth of the tooth,

5.6 Inspection regulations
GR/7.18620.1—2002
Usually the measurement shall be carried out in the middle of the tooth height adjacent to the tooth width. If the step is greater than 250 mm, two additional tooth ratio measuring discs shall be added. The measurement shall be carried out at a width of about 15 mm on each side of the pitch tooth. The error shall be measured at least at three evenly distributed positions on the same surface.
6 Inspection of single pitch and pitch ratio deviation 6.1 Overview
The inspection of the error includes measuring its actual value (degree) or comparing the distance between the tooth surfaces on the same side of the gear (see Figure 3).
And the inspection of the normal, end and pitch boundary areas are not considered. These two functions cannot be measured along the base plane because they are not related to the gear axis.
Monitoring Figure 3 Step distance (

, dirty, for a group of gears with multiple teeth, the difference in the technical calculation method and the single tooth version data
When using the negative force method to measure the tooth, the actual measured theoretical attenuation angle will be used for each measurement position, and the radial distance height between the contact head and the point contact will be multiplied to get the service value. The lower can be compensated by subtracting the value of the tooth surface -1 from the value of the tooth surface. GR/z.18620.1—2002 Fnf-Figure

Figure: Table 1 shows the pitch optimization solution of the tooth (2-18) 6.? The most common devices for measuring the accuracy of a single pitch extension are a pitch comparator with two measuring heads and an angle gauge with only one measuring head. The two detection methods are described in .2.7 and 5.22 respectively. A coordinate measuring machine with a rotating table can also be used to measure the pitch deviation of a tooth. The selection method used is basically the same as the principle described in 6.2.2 (see Figure 1-1). KAa
GD/218620.2002
Figure, full face pitch, and single tooth deviation 6-2.1 Use a tooth comparison (period) to measure the position of the two heads of a single tooth pitch. The two heads should be on the same half of the wheel axle and in the same mold surface. The direction of the probe movement should be parallel to the measurement. Because it is difficult to get the exact value of the radius, the pitch comparison instrument is rarely used to detect the actual value of the end face tooth alignment. This instrument measures the appropriate pressure and is sufficient to determine the deviation.
Some gears with a pitch ratio of 1/2 are equipped with only a guide slide. The fast measuring head can easily reach the same diameter depth, usually close to the wheel step (Figure 6). The gear being tested rotates slowly, rotating continuously or intermittently around the differential center, while the head on the guide section moves back and forth in the measuring area.
Figure 6.2.2 Detection of single tooth by negative indexing method (-head) The use of the indexing indexer must be coordinated with the gear diameter, as shown in the figure? As shown in the figure, by moving the measured part back and forth slightly on the moving part, the position error of the gear can be measured, and the measured data represents the position deviation of the gear surface for the selected reference surface or zero tooth surface. This record should show the average position error of the gear on the brush (production error) of each tooth, as far as possible, and the negative value should be shown: 8/218 620.1—2007
Figure 7 Test pitch with angular position
6.3 Test pitch with pitch comparison method Figure 8 shows normal tooth moment and normal pitch deviation
Figure Normal pitch and normal pitch deviation (normal section) When measuring, when there is only a portable comparator to test the "normal" tooth without deviation, and no other data, only the normal pitch is required to measure the surface gear deviation. As shown in the instrument introduced in Figure 9, the top circle of the gear is used for positioning, it must have sufficient concentricity with the gear axis. Other comparators with the same purpose have different positioning methods, and do not use the tooth as a positioning surface. In the industry, the tolerance value of the standard GR1M.1 is used to measure the deviation of the gear teeth. Because the tolerance value in the standard GR1M.1 refers to the end face pitch, the normal pitch value must be converted to the weak face value before comparing with the standard.
It is related to:
or accounted for, the tolerance value can be multiplied by the center, which usually requires less calculation. The deviation value is not taken into account when making a tooth plan. The deviation is 6.4 base mesh teeth, and the base reading is invited to follow the measurement of HYKAONY KA
