Embodiment Construction
[0040] The material of the arc-shaped cylindrical worm gear of the reducer is cast tin bronze ZQSn10-1, and its processing route is: milling both ends of the gear teeth, the upper end surface -> rough expansion, fine expansion, reaming -> key slot -> correction worm gear -> Hobbing gears -> Heat treatment -> Shaving gears.
[0041] By collecting and calculating on-site data, the list analysis table of each process is obtained, taking the first process of milling as an example, as shown in Table 3 below:
[0042] table 3
[0043]
[0044] The qualitative indicators in the indicators are scored by process, technology, and production personnel experts. The scoring results are shown in Table 4 below.

The invention relates to a green evaluation method for the machining process of a reducer arc-tooth cylindrical worm gear, which relates to the technical field of the machining of the reducer arc-tooth cylindrical worm gear. At first, according to that green manufacturing requirement of arc tooth cylindrical worm gear, the green attributes of resources and environment corresponding to the manufacturing process are established, and the green attributes of resources and environment corresponding to the manufacturing process, based on the fuzzy comprehensive evaluation method to quantify and unify the qualitative index data, Unexpected data envelopment analysis is used to evaluate the greenness of a single process, and then integrating the input and output of each process. The relationship between resource consumption and environmental impact in the whole process of worm gear manufacturing is analyzed by using the input-output method. Finally, according to the results, corresponding measures are made to improve the resource utilization rate, reduce the negative environmental impact and improve the process environmental friendliness of worm gear in the process of machining the arc tooth cylindrical worm gear.
Description
technical field [0001] The invention relates to the technical field of mechanical processing of arc-shaped cylindrical worm gears of reducers. Background technique [0002] A large amount of raw materials and energy are consumed during the machining process of the arc-shaped worm gear of the reducer, and a large amount of waste is generated, causing serious environmental pollution. In order to improve these problems, the environmental impact and resource consumption are considered comprehensively during the manufacturing process of worm gears, and practical methods are devised to effectively utilize resources as much as possible, reduce pollution and waste, and realize green manufacturing of worm gears. Among them, green evaluation technology is an important basis for realizing green manufacturing. It analyzes and evaluates the types, characteristics and related information of resource and environmental attributes in the manufacturing process, and clarifies the impact of res...
