Description

Technical Field

[0001] This application relates to the field of turboshaft engine assembly and disassembly technology, and in particular to a multi-functional disassembly and assembly vehicle for turboshaft engines. Background Technology

[0002] The main body of a certain type of turboshaft engine consists of core power components, electrical system accessories, air system accessories, fuel system accessories, cooling and lubrication system, and other systems. Disassembly, assembly, and transportation are routine operations during turboshaft engine maintenance.

[0003] The current operating method involves disassembling, assembling, and inspecting each component on fixed tooling before finally assembling them together on the final assembly platform. This process is inefficient and requires a large number of tooling fixtures. The coaxiality of the connecting parts on both sides of the final assembly platform is critical, requiring the inner polygon of the sleeve to mate with the outer polygon of the shaft, which demands high machining precision and incurs high processing costs.

[0004] Therefore, we propose a multi-functional disassembly and assembly vehicle for turboshaft engines. Utility Model Content
