Abstract

The invention provides an assembling and disassembling device for a bearing inner ring compression nut. The device comprises a main support, a fixing table, an operating table, a lifting clamp, a pressing plate, a torque amplifier and a bushing wrench, wherein the main support at least comprises a first support and a second support which can move relative to each other, the first support and the second support are connected through a connecting piece, height adjustment of the main support is achieved, the device adapts to rotor assemblies of various specifications, the fixing table and the operating table are fixedly arranged on the main support, the fixing table is used for fixing a rotor assembly bearing a bearing inner ring, the operating table is used for bearing the torque amplifier,the lifting clamp is arranged on the main support and can move relative to the main support, the pressing plate is connected with the lifting clamp, a rotor in the rotor assembly is limited through the pressing plate and the lifting clamp, the torque amplifier is mounted on the operating table, and the bushing wrench is arranged between the torque amplifier and the bearing inner ring compression nut, sleeves the rotor and is used for transmitting a torque of the torque amplifier to the bearing inner ring compression nut so as to tighten the bearing inner ring compression nut.

Description

technical field [0001] The application belongs to the technical field of aero-engine assembly, and in particular 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 the aero-engine, the compression nut is often used as the fastening method of the inner ring of the bearing. Such as 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, and it needs to be precisely controlled by a special torque wrench. For compression nuts that require a large tightening torque, auxiliary equipment such as torque amplifiers are also required. During the tightening process of the compression nut, the tightening force will act on the...
