Description

Technical Field

[0001] The invention relates to the technical field of generators, and in particular to an easily detachable engine and generator connection structure. Background Art

[0002] There are many generator sets on the market now, and most of them are directly connected with the conical shaft generator and the conical shaft engine. A long bolt is used to pass through the entire generator shaft. The end of the engine shaft has a threaded hole. The long bolt is screwed into the threaded hole, so that the conical surfaces of the generator conical shaft and the engine conical shaft slowly mesh until elastic deformation occurs, and they are tightly held together. The friction generated by the elastic deformation allows the two shafts to rotate together. With this structure, the two conical shafts are not easy to disassemble. When there is a problem with the generator set, the generator and the engine cannot be easily disassembled. Special tooling is required to assist in disassembly, and the process is relatively cumbersome. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an easily detachable engine and generator connection structure with a simple structure that can realize the detachment of the generator and the engine without the aid of special auxiliary tooling. The present invention is achieved through the following technical solutions:

[0004] A structure for connecting an engine and a generator that is easy to disassemble and assemble, wherein a bolt clearance hole is provided at the rear of a tapered shaft of the generator, a tapered hole is provided at the front end, a threaded hole is provided at the center of the end of the tapered shaft of the engine, the tapered hole cooperates with the outer wall of the tapered shaft of the engine, a long bolt is passed through the bolt clearance hole, a nut is fixedly installed at the rear of the long bolt outside the tapered shaft of the generator, a boss is fixedly provided at the front of the long bolt, and the diameter of the boss is larger than the aperture of the threaded hole of the tapered shaft of the engine and the aperture of the bolt clearance hole of the tapered shaft of the generator.

[0005] Optimally, the nut and the long bolt are fixed by thread fastening glue.

[0006] Optimally, the long bolt is provided with external threads at the rear end portion and the front portion of the boss.

[0007] Advantageous Effects of the Invention

[0008] An easy-to-disassemble engine and generator connection structure can make the engine and generator easy to disassemble and assemble, and the maintainability is simpler and faster. The entire disassembly and assembly process can be completed with only one wrench. No special auxiliary tooling is required, and the economy is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] A structure for connecting an engine and a generator that is easy to disassemble and assemble, wherein a bolt clearance hole 6 is provided at the rear of a generator tapered shaft 3, a tapered hole 8 is provided at the front end, a threaded hole 2 is provided at the center of the end of an engine tapered shaft 1, the tapered hole cooperates with the outer wall of the engine tapered shaft, a long bolt 4 is passed through the bolt clearance hole, a nut 5 is fixedly installed at the rear of the long bolt outside the generator tapered shaft, a boss 7 is fixedly provided at the front of the long bolt, and the diameter of the boss is larger than the aperture of the threaded hole of the engine tapered shaft and the aperture of the bolt clearance hole of the generator tapered shaft.

[0013] Optimized, the nut and the long bolt are fixed by thread fastening glue, which makes the fixation more convenient and easy to disassemble and assemble.

[0014] Optimally, the long bolt is provided with external threads 9 at the rear end and the front part of the boss for easy processing.

[0015] The present invention protects an easily disassembled engine and generator connection structure, which has threads at both ends of the long bolt and a boss structure near the engine shaft end. During installation, first insert the long bolt into the generator cone shaft, then use threaded fastener to firmly fix the lock nut and the tail of the long bolt, rotate the lock nut, the lock nut squeezes the generator cone shaft forward toward the engine end, and the boss of the long bolt rests on the front end of the engine cone shaft, so that the engine cone shaft and the generator cone shaft are tightly held. During disassembly, rotate the lock nut in the opposite direction, the boss of the long bolt will move outward, and when it moves to the bolt clearance hole, it will touch the inner end face of the generator cone shaft, continue to rotate the lock nut, the long bolt boss will squeeze the inner end face of the generator cone shaft to move the generator shaft outward. After reaching a certain force, the generator cone shaft and the engine cone shaft will separate.

[0016] The diameter of the boss is larger than the diameter of the threaded hole of the engine cone shaft and the diameter of the bolt clearance hole of the generator cone shaft, so that the boss is convenient for limiting the position during installation and plays the role of dragging the generator cone shaft outward during disassembly.

[0017] In summary, the easily disassembled engine and generator connection structure protected by the present invention has a simple structure and can realize disassembly and assembly of the generator and the engine without the aid of special auxiliary tooling.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
