Calculation of the processing dimensions of shaft gears
1 Calculation of main dimensions of shaft gears
The shoulder size of the shaft gear is more important. This size will affect the assembly position of the bearing and the adjustment of the assembly gap of the gear in the casing. The dimensional tolerance requirements are strict, and it needs to be processed many times, and there are many rings. The calculation is very difficult, and it has always been a major difficulty that plagues craftsmen.
2 Calculation of the length of gear common normal
In the process of gear manufacturing, gear hobbing, gear shaping, gear grinding, etc., the common normal length of N teeth must be given, which is convenient for processing and measurement.
3 Single tooth size calculation
If the number of teeth of the gear is an odd number, the larger size cannot be measured when measuring the diameter of the addendum circle and the diameter of the tooth root circle. Therefore, it needs to be converted into a single tooth length size, and then measured with a caliper or a micrometer.
To sum up, as long as you understand the characteristics of shaft gear processing, arrange the processing route reasonably, grasp the key points in the gear process planning, master the matters needing attention in each main process, and correctly use the above-mentioned dimensional chain distribution , Calculation of dimensional chain and length of common normal line, etc., the preparation of shaft gear machining process regulations will be much simplified, shorten the preparation time, which is conducive to the development of new machines, and provides certain guidance for new technicians when preparing similar process regulations. effect.
