Description
Technical Field

Background
As shown in figures 1-9, the thrust reverser widely used in the turbofan aircraft engine with large bypass ratio at present is a C-shaped cascade thrust reverser (1), and the C-shaped cascade thrust reverser is composed of two half C-shaped culverts (11, 12) with the same left half and right half functions and similar structures. The left and right semi-C-shaped culvert (11, 12) structures are respectively composed of a fixed structure (13) and a movable outer cover (14). The upper sliding rail beam (131) and the lower sliding rail beam (132) of the fixed structure are respectively provided with a sliding rail groove for the sliding of an upper sliding rail (141) and a lower sliding rail (142) of the movable outer cover (14), a quick-wear replaceable sliding rail bushing (15) is arranged in the sliding rail groove, and the sliding rail bushing (15) is generally composed of an aluminum alloy sliding rail bushing (15) and a nonmetal Teflon layer (2) bonded in the sliding rail bushing.
The teflon has the characteristics of acid resistance, alkali resistance, high temperature resistance and extremely low friction coefficient, so that the teflon can be used as a lubricant of the sliding rail bushing (15). However, due to the lubricating property of teflon materials, the teflon materials are extremely difficult to stick and are extremely easy to break, so that the rejection rate is high.
In the process of pasting the Teflon layer (2) on the slide rail bushing (15), the slide rail bushing (15) is small in inner section size (about 15mm), thin in wall thickness (about 2mm), large in section rigidity, long in length (up to 1300mm) of the slide rail bushing (15), and the Teflon layer (2) is hard. Therefore, when the Teflon layer (2) is adhered, firstly, adhesive glue is coated on one side, which is attached to the slide rail bushing (15), of the Teflon layer (2), then the Teflon layer (2) coated with the adhesive glue is placed into the slide rail bushing (15), and finally, a core rod (16) is inserted into the slide rail bushing (15) to compress the Teflon layer (2).
In order to ensure the adhesion effect of the Teflon layer, the core rod (16) is required to compress the Teflon layer (2), so that a small gap is reserved between the core rod (16) and the inner profile of the slide rail bushing (15). In the actual bonding process, however, the small clearance between the core rod (16) and the inner profile of the slide rail bushing (15) makes the insertion of the core rod (16) difficult, and the surface of the Teflon layer (2) is easily damaged; meanwhile, in the insertion process of the core rod (16), the Teflon layer (2) and the slide rail bushing (15) are easy to slide relatively, so that the adhesive glue on the Teflon layer (2) slides; in addition, because the section rigidity of the slide rail bushing (15) is larger, a gap is left between the core rod (16) and the inner profile surface of the slide rail bushing (15), and the teflon layer (2) cannot be completely pressed by the core rod (16), so that the teflon layer (2) and the slide rail bushing (15) are not firmly bonded.
