Embodiment Construction

[0033] The core of the present invention is to provide a method for processing combined herringbone gear parts, so that after a single helical inner ring gear is processed separately and combined, the centering accuracy of the two ring gears can be guaranteed to meet the requirements of the drawings.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] see figure 1 and figure 2 , figure 1 The process flow chart of the processing method of the combined herringbone tooth parts provided by the embodimen...

Abstract

The invention discloses a method for machining a combined herringbone tooth part. The method includes the steps of machining slots of two helical tooth part and machining an assembly hole on a first helical tooth part; aligning centering errors of the herringbone tooth and machining several assembly holes evenly distributed on a second helical tooth part; aligning centering errors of the herringbone tooth and performing assembly; re-inspecting the centering errors of the herringbone tooth and issuing a centering inspection report; aligning the pitch circle run-out according to the centering inspection report and fastening the pitch circle run-out through a bolt after centering of the herringbone tooth; finishing pinholes on the two helical tooth parts and drilling assembly holes left on the second helical tooth part; re-inspecting the centering errors of the herringbone tooth and providing a correction direction of one of the two helical tooth parts; and decomposing the two helical tooth parts and grinding teeth according to the correction direction to obtain the finished product. According to the method, through three times of alignment of the herringbone tooth centering, two times of error re-inspection of the herringbone tooth centering, tooth grinding, slotting, matching, assembly hole drilling and tooth grinding, drawing design requirements are met.

Description

technical field [0001] The invention relates to the technical field of herringbone gear processing, and more specifically, relates to a processing method of a combined herringbone gear part. Background technique [0002] In recent years, with the continuous advancement of science and technology, herringbone gear planetary transmission is widely used, especially in some special industries such as nuclear power and oil drilling. Due to the strict requirements on the volume and weight of the gearbox, the gearbox often needs to Gear planetary transmission to design. [0003] Due to the light weight, small size and compact transmission structure of the herringbone ring gear involved in some specific fields, the herringbone ring gear is required to have a thinner wall thickness, smaller relief groove, and higher precision requirements. advanced features. In order to meet the above requirements, gear grinding must be carried out. The usual herringbone gear is integrally formed, ...
