Problems solved by technology
[0003] In the assembly process of existing similar products, when the gear grinding machine grinds the addendum circle, the grinding accuracy is different from the installation reference accuracy, and the pitch circle is used to indirectly align the pitch circle as the reference for assembly, and the pitch circle rods have the same size There are errors in the alignment, the number of teeth is large, and the alignment is labor-intensive. If it is a helical gear, there will be errors in the alignment of the pitch round bar, which cannot fully reflect the accuracy of the teeth.
Therefore, the above factors are very likely to cause the loss of product accuracy, and eventually lead to unqualified product assembly quality

Embodiment Construction
[0017] The main processes of the method for processing the ultra-large precision gear ring of the present invention include a finishing process, a gear hobbing process and a gear grinding process.
[0018] The specific steps of the finishing process are as follows: First, take one of the end faces of the ring gear workpiece as the reference end face, use the reference end to face the ring gear 1 for positioning and clamping, and turn the non-reference end face and gear of the ring gear 1 in one clamping. The top circle, and a aligning belt is driven out of the inner hole of the ring gear 1, wherein the single side allowance of the tooth top circle is 0.2-0.4mm.
[0019] The specific steps of the gear hobbing process are: align the reference end surface of the ring gear 1, and use a dial indicator or dial indicator to mark the tip circle until the dial indicator or dial indicator beats the same, then the ring gear 1 Clamping, and then hobbing according to process requirements.

The invention relates to the technical field of extra-large precision gear rings, in particular to a machining method of an extra-large precision gear ring, the gear ring and an assembling method of the gear ring. The machining method mainly comprises a finish turning procedure, a hobbing procedure and a gear grinding procedure. The gear grinding procedure comprises the steps that first, the gear ring after hobbing is subjected to locating clamping, then the gear ring is subjected to gear grinding according to the technological requirement, after gear grinding, a gear grinding wheel is used for forming an alignment belt by grinding on the outer circle of the gear top of the gear ring, and during gear top circle grinding, the included angle between the tooth grinding wheel and the end face of the gear ring is 35 degrees-45 degrees. According to the extra-large precision gear ring, the gear ring and the assembling method of the gear ring, synchronization of gear grinding precision and product mounting reference precision is guaranteed, and a new method for improving assembling precision and assembling efficiency is obtained.
Description
Technical field [0001] The invention relates to the technical field of gear rings, in particular to a method for processing super-large precision gear rings, and a method for assembling the manufactured gear rings and the gear rings. Background technique [0002] With the development of national defense, aerospace, and aerospace industries and the large-scale equipment of basic industries such as energy, large-scale, high-performance, high-precision CNC machine tools are needed. As the core parts of machine tools, the machining accuracy of ultra-large precision ring gear products is especially valued. [0003] In the assembly process of existing similar products, when the gear grinding machine grinds the addendum circle, the gear grinding accuracy is different from the installation reference accuracy, and the pitch rod is used to indirectly align the pitch circle as the basis for assembly, and the pitch rod size is consistent. There are errors in performance, the number of teeth i...
