Abstract

The invention belongs to an aero-engine measurement technology, and relates to a device for measuring the coaxiality of a bearing seat of an aero-engine combustion chamber casing. The device is characterized by consisting of a locating sleeve (4), a front needle rolling bearing (5), a front baffle ring (6), a rear needle rolling bearing (7), a rear baffle ring (8), an end cover (9), an end cover screw (10), a bracket (11), a bracket screw (12) and a dial indicator (15). The invention provides the device for measuring the coaxiality of the bearing seat of the aero-engine combustion chamber casing, so that the measurement problems of the diameter sizes of the components such as the bearing seat and a mounting side of the casing as well as the coaxiality and the jerk value of an engine rotor in the casing experiment can be solved, and the dynamic balance accuracy of the engine rotor can be guaranteed.

Description

technical field [0001] The invention belongs to the measurement technology of aero-engines, and relates to a coaxiality measurement device for a casing bearing seat of an aero-engine combustion chamber. Background technique [0002] In the test of the aero-engine casing, it is necessary to measure the coaxiality and runout of the engine rotor and the diameter of the bearing seat, mounting edge and other parts of the combustion chamber casing structure, see figure 1 , the right end of engine rotating shaft 1 is positioned at the inside of combustion chamber casing 2, and the right port of combustion chamber casing 2 has bearing block 3. The right end of the engine rotating shaft 1 is a two-stage stepped shaft, the left section of the two-stage stepped shaft is a large-diameter section 1a, the middle section is a middle-diameter section 1b, and the right end is a small-diameter section 1c. The inner cylindrical surface 3a of the central hole of the bearing seat 3 is a detecti...
