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 technology for combining a left-handed ring gear and a right-handed ring gear into a high-precision herringbone gear. The technology comprises the following steps of gear grinding machining conducted on the left-handed ring gear and the right-handed ring gear, the combining technology for combining the left-handed ring gear and the right-handed ring gear into the high-precision herringbone gear and the specific adjustment process and a technique for recovering the high-precision herringbone gear again after disassembly. The technology improves the adjustment method forcombining the left-handed ring gear and the right-handed ring gear into the high-precision herringbone gear, improves the centering degree and tooth portion precision of the herringbone gear and guarantees the precision of the reassembled herringbone gear after disassembly.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a process for combining left-handed and right-handed inner ring gears into high-precision herringbone teeth. Background technique [0002] The combination of left and right-handed ring gears with herringbone teeth is one of the main components of an engine fan drive gearbox such as a large engine for large equipment. Left and right-handed ring gear parts have thin walls and are variable; the precision grade of the internal teeth (GB10095-2008) meets the requirements of level 4, and the error of the rod spacing of left and right-handed ring gears cannot be greater than 0.05mm; The centering degree of herringbone teeth combined with the ring gear is not greater than 0.08mm, and the symmetry degree is not greater than 0.08mm. [0003] When this kind of parts are produced in the market at present, when assembling, the operation is troublesome and the assembling time...
