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

The present disclosure relates to an assembly tool in the field of gas turbine manufacturing, and in particular to an assembly tool for assembling a bearing outer ring to a bearing seat of a turbine rear casing, including: a guide portion capable of guiding toward the turbine rear casing during the assembly process The bearing outer ring provides radial positioning and circumferential positioning for the bearing outer ring; and the pushing part is relatively movable with the guide part and can push the bearing outer ring in the axial direction during the assembly process . According to the embodiment of the present disclosure, the assembly tool can correctly and smoothly install the bearing outer ring of the turbine rear bearing on the bearing mounting seat, thereby shortening the assembly cycle.
Description
an assembly tool technical field [0001] The present disclosure relates to the field of gas turbine manufacturing, and in particular, to an assembly tool. Background technique For gas turbines, especially aviation gas turbines, in the working process, the rotating shaft is driven by the turbine High-speed rotation, thereby driving the compressor to do work on the gas, increasing the total pressure of the gas. In the high-speed rotation state of the rotating shaft (typical Bearings often work under high temperature, high speed, heavy load and vibration in complex environments. At this time, the reliability of the bearing not only affects the rotation accuracy and friction coefficient of the rotating shaft, but also has a direct relationship with With regard to the safety of aviation gas turbines, Under the situation that the actual temperature of the inlet of the turbine of the aero-engine has exceeded 1700K, the shaft of the turbine part Bearings will be subject...
