Mounting distance measuring device and measuring method of bevel gear pair

Abstract

The invention, which belongs to the technical field of aeroengine assembling, discloses a mounting distance measuring device and measuring method of a bevel gear pair. A first core shaft for simulating the working state of a driving bevel gear, a second core shaft for simulating the working state of a driven bevel gear, a first mandril, and a second mandril are arranged at the mounting distance measuring device, wherein the first mandril and the second mandril are in contact and cooperation with each other by a spherical element; and the axis of the first mandril and the axis of the second mandril are intersected at the center of the spherical element. Therefore, the spatial position of the mounting space, that is, the spatial position of the axis intersection point of the bevel gears is transformed into a measurable dimension, so that problems that the mounting distance measuring is not carried out accurately, the actual working state can not be reflected, and the measurement period is long can be solved. The measuring device is suitable for measuring the mounting distance when the bevel gear axis is at an arbitrary angle; the working state of the bevel gear is restored effectively by using methods of compensation and limiting; a few of measuring data are needed; the operation method is simple; the mounting distance of the driving bevel gear and the mounting distance of the driven bevel gear can be measured accurately; and the adjusting pad is selected correctly and the tooth space is real.

Description

technical field [0001] The invention relates to the field of aero-engine assembly, in particular to a bevel gear pair installation distance measuring device and a measuring method. Background technique [0002] Bevel gear pairs are commonly used in aero-engine transmission mechanisms. In order to ensure that the bevel gear pairs are in the ideal position and the gears mesh normally, it is necessary to compensate the difference between the actual installation distance of the casing and the theoretical installation distance of the gears. Accurately measuring the installation distance of the casing is a key process. For the measurement method of the installation distance of the bevel gear pair with an axis intersection angle of 90°, refer to figure 1 , push the active mandrel 11, make the active mandrel 11 just contact with the driven mandrel 12, measure X1; push the driven mandrel 12, make the driven mandrel 12 just contact with the active mandrel 11, measure Y2, then the mac...
