Problems solved by technology

[0003] When this kind of parts are produced in the current market, when they are combined, the operation is troublesome and the combination time is long. After the combination, the alignment of the herringbone teeth is 0.15mm out of tolerance, and the precision of the internal gear is grade 6, so there are still certain defects.

Abstract

The invention provides a process for combining left and right-handed inner gears into high-precision herringbone teeth, which includes the following steps: grinding of left-handed and right-handed inner gears; combining left-handed and right-handed inner gears into high-precision herringbone Combination process of teeth and specific adjustment process; after the left and right-handed inner ring gears are combined into high-precision herringbone teeth, the process method can be restored to high-precision herringbone teeth after being disassembled. The invention improves the left and right-handed The adjustment method that the internal ring gear is combined into high-precision herringbone teeth also improves the alignment of the herringbone teeth and the accuracy of the teeth, and solves the accuracy of repeated assembly after disassembly.

Description

Technical field [0001] The present invention relates to the field of mechanical manufacturing techniques, and more particularly to a process of combining a high-precision human word teeth in a left and right-convexes. Background technique [0002] Left, and right-handed intermediate ring gear combination adult words are one of the main components of engine fan drive gearboxes (such as large engines of large equipment). Left, right-handed ring gear parts wall thin, variability; internal tooth precision level (GB10095-2008) is 4-level requirements, and the rod of left and right-conveying gears cannot be greater than 0.05mm; left, right rotation The intermediate of the ring gear combination adult words is no more than 0.08 mm, and the symmetry is not more than 0.08 mm. [0003] Such parts are currently in the current market, when combined, trouble, long combination time, composite human word teeth pair moderate 0.15mm, and the internal gear accuracy is 6, there is still a deficienci...
