Abstract

The application provides an assembly and disassembly device for the compression nut of the inner ring of the bearing, including: a main bracket, at least including a first bracket and a second bracket that can move with each other, and the first bracket and the second bracket are connected by a connecting piece , realize the height adjustment of the main support to adapt to rotor assemblies of various specifications; the fixed table and the operation table fixedly arranged on the main support, the fixed table is used to fix the rotor assembly bearing the inner ring of the bearing, and the operation table is used to carry the torque amplifier ; a lifting fixture arranged on the main support and capable of moving relative to the main support; a pressing plate connected to the lifting fixture, through which the rotor in the rotor assembly is limited by the pressing plate and the lifting fixture; a torque amplifier installed on the console; and setting The bushing wrench between the torque amplifier and the compression nut of the inner ring of the bearing, the bushing wrench is set on the rotor, and is used to transmit the torque of the torque amplifier to the compression nut of the inner ring of the bearing to tighten the compression nut of the inner ring of the bearing.

Description

technical field [0001] The application belongs to the technical field of aero-engine assembly, and particularly relates to an assembly and disassembly device for a compression nut of a bearing inner ring. Background technique [0002] In the assembly structure of the main bearing of aero-engine, the compression nut is often used as the fastening method of the inner ring of the bearing. like figure 1 In the typical bearing assembly structure shown, the inner ring of the bearing 2 is fixed on the rotor 1 through the compression nut 3. [0003] The tightening torque control of the compression nut during assembly has an important impact on the stability of the bearing assembly structure, which needs to be precisely controlled by a special torque wrench. For the compression nut that requires a large tightening torque, auxiliary equipment such as a torque amplifier is also required. During the tightening process of the compression nut, the tightening force will act on the rotor...
