Embodiment Construction

[0034] In order to make those skilled in the art better understand the technical scheme of the present invention, the following in conjunction with the attached Figure 1-3 The present invention will be further described in detail with specific embodiments.

[0035] On the one hand, the present invention discloses a method for processing a multi-split box body, such as image 3 shown. Wherein, the multi-shunt split-type box processing method is used for processing the multi-shunt split-type box.

[0036] The multi-shunt split box is a box with any number of parallel holes. In this embodiment, the multi-shunt split box includes four four-shunt bearing holes 4 and eight eight-shunt bearing through holes 5 as an example.

[0037] The multi-shunt split box includes a first part 1, a second part 2 and a third part 3, the number of the first part 1 and the second part 2 is 2, and the number of the third part 3 is 1. Two second parts 2 are assembled on both sides of the third part...

Abstract

The invention provides a method for processing a multi-splitting split-type box body. Firstly, rough mill the joint surface of each part of the box body; assemble each part into a box body to draw lines as a whole, disassemble the box body, and use the overall line marking as a benchmark Semi-finish milling joint surface; drill reference pin holes on each part; assemble the second part, third part and one first part, and install them on the boring machine table as a whole, first rough machine the four-shunt bearing hole, and then Assemble the above-mentioned whole and the first part into a box body, and roughly machine the through hole of the eight-shunt bearing; disassemble the box body, remove the stress, align it with the reference pin hole, and finish milling each joint surface; assemble the parts According to the position error between the hole systems, each hole is semi-finely bored; the overall stress is eliminated by vibration, and each hole is finely bored according to the deviation between the actual position of each hole and the ideal position. The invention improves the position accuracy of the bearing hole of the box body.

Description

technical field [0001] The invention relates to the technical field of mechanical dynamics, in particular to a multi-distribution split box body and a processing method thereof. Background technique [0002] The wind power gearbox is a very critical part of the wind turbine, and the processing quality of the box directly affects the quality of the fan. [0003] Wind power gearboxes generally include a structural layout of one-stage planetary, two-stage parallel or two-stage planetary and one-stage parallel planetary. In order to further meet the lightweight design requirements of offshore wind power and achieve a high degree of maintainability, wind power gearboxes currently adopt a structural layout of all parallel axes and multiple shunts. However, the processing accuracy of this multi-shunt box is often low, which directly affects the load distribution of the box and the vibration and noise indicators of operation. [0004] Therefore, how to improve the position accurac...
