Abstract
A processing method of a super-large-diameter multi-segment toothed ring relates to the field of processing techniques of multi-segment toothed rings and comprises the technological processes of blank segmentation, end surface rough-turning, low-temperature tempering, end surface finish-turning, excircle and inner hole milling, drilling processing and tooth processing. According to the processing method of the super-large-diameter multi-segment toothed ring, the problems of deformation and out-of-tolerance dimension in the processing process of the super-large-diameter multi-segment toothed ring are radically solved, the production process is easy to realize, the product qualification rate is extremely high, the production cost and the purchase cost are lowered, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of processing methods for multi-segment gear rings, in particular to a processing method for super-large-diameter multi-segment gear rings. Background technique [0002] The ultra-large diameter multi-segment gear ring refers to the diameter greater than 5000mm and less than 8000mm, the outer diameter or inner diameter has teeth, and there are requirements for the machining accuracy of the teeth, and the working condition is segmented. Due to the characteristics of its own structure, the ultra-large-diameter multi-segment gear ring undergoes multiple processes during the processing process. During the processing process, a large processing stress is accumulated, so that after the gear ring is finished and segmented, each gear ring segment produces a large plastic and elastic deformation. At present, there is no mature processing technology in the field of processing this kind of super large diameter multi-segment gea...
