[0018] like Figures 1 to 7As shown, a generator set compression fit structure includes an arc-shaped main body fitting connection seat 1 with an opening downward, and the upper and lower end surfaces of the main body fitting connection seat 1 are parallel arc surfaces. When installing and fitting, the upper and lower directions can be matched and connected with the fitting surface in a larger area. When the fitting connection is not performed, a certain matching space can be provided in the left and right directions, so as to ensure that the fitting position is more convenient for disassembly and assembly during later use. The front and rear positions of the upper end of the main body fitting connection seat 1 are respectively provided with an integrally formed arc-shaped installation compression fixing matching boss 2, which is a main body matching structure for the main body to be compressed and combined. The upper end surface of the main body fitting connection seat 1 and the upper end surface of the installation compression fixing matching boss 2 are on the arc surface of the same diameter, which ensures the flatness of the structure. A V-shaped compression fitting connection groove with an opening downward is formed between the front and rear directions of the main body fitting connection seat 1 and the lower end of the installation compression fixing matching boss 2, which can play a role of limiting after matching, and ensures better stability of the compression matching. The components that match in the front and rear directions have a more stable combination effect. The upper end of the main body matching connection seat 1 is located at the center position of the left-right direction and is provided with a V-shaped combination guide matching groove 3 with an opening upward, and the lower end of the combination guide matching groove 3 is provided with a combination stable matching groove 4, which can be associated and matched with the upper end main body support frame components to ensure the overall combination strength. The upper end arc of the main body matching connection seat 1 is provided with arc-shaped matching support limit grooves 5 located on the left and right sides of the combination guide matching groove 3, which can be matched and supported with the middle part of the shaft component, and can provide support for it, which is safer and more reliable when performing the rotation of the shaft component, and can have a stronger bearing capacity. The middle position in the front-to-back direction can form an anti-loosening matching effect of the upper and lower staggered combination, and the overall matching stability during use is better. When installed, it can be tightly combined with the components that match in the front and rear directions through the clamping structure in the front and rear directions. The upper end is provided with two matching support limit grooves, which can support and cooperate with the middle part of the shaft component to provide it with a limiting support function, and the combined stable connection groove in the middle position can be staggered and combined with the internal stable frame component to make the matching stability between different components better, and the matching connection operation during the overall installation is also more convenient. It has reliable matching safety during later use, is not easy to loosen in a vibration environment, has stronger durability during use, can effectively increase the maintenance cycle during use, thereby reducing maintenance and use costs.

[0019] Preferably, the left-right length of the mounting clamping and fixing mating boss 2 is the same as the left-right length of the main mating connecting seat 1, so that the strength of the outer clamping structure is higher and the mating safety during mating can be further improved.

[0020] Preferably, spare fastening assembly connection holes are respectively provided on the left and right end faces of the main body and the connecting seat 1, which can be fastened and assembled with screws as needed.

[0021] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
