Problems solved by technology

The existing installation process of the bearing outer ring is often based on the hoisting of the bearing outer ring, relying on manual position judgment and manual pushing. During the process of ensuring the push-in direction of the ring, it is easy to cause installation failure, and it is easy to cause wear and tear on the bearing outer ring or the mounting seat due to bumps between the bearing outer ring and the mounting seat, which may cause safety hazards during the working process of the bearing

Abstract

The invention relates to an assembly tool in the field of gas turbine manufacturing, in particular to an assembly tool for assembling a bearing outer ring to a turbine rear casing bearing seat. The assembly tool comprises a guide part and a pushing part. The guide part is capable of guiding the bearing outer ring to a turbine rear casing in the assembling process and providing radial positioning and circumferential positioning for the bearing outer ring. The pushing part can move relative to the guide part and can push the bearing outer ring in the axial direction in the assembling process. According to the embodiment of the assembly tool, the assembly tool can enable the bearing outer ring of a turbine rear bearing to be correctly and smoothly mounted on a bearing mounting seat, so that the assembly period is shortened.

Description

technical field [0001] The disclosure relates to the field of gas turbine manufacturing, and in particular to an assembly tool. Background technique [0002] For gas turbines, especially aviation gas turbines, during the working process, the rotating shaft rotates at a high speed driven by the turbine, thereby driving the compressor to do work on the gas and increasing the total pressure of the gas. Under the high-speed rotating state of the rotating shaft (typical rotating shaft speed is 5000-25000 rpm), the bearings often work in the environment of high temperature, high speed, heavy load and complex vibration conditions. At this time, the reliability of the bearing not only affects the rotation accuracy and friction coefficient of the rotating shaft, but also directly affects the safety of the aviation gas turbine. [0003] At present, the actual temperature of the inlet of the aero-engine turbine has exceeded 1700K, and the bearing of the turbine will withstand an extra...
