Abstract
An intermediate case lining structure with pin holes is characterized by comprising the pin holes and a barrel-shaped lining structure. The pin holes are formed in the circumference of the barrel-shaped lining structure. An annular groove is formed in the outer wall of the barrel-shaped lining structure. The number of the pin holes is six. The intermediate case lining structure with the pin holes has the advantages that the requirement for the simple machining technique is met, the quality of repairing an engine is guaranteed, the bottleneck problem of the field technology is solved, and the production can be carried out successfully.
