Technical Field

The invention relates to the technical field of generators, in particular to a connecting structure of an engine and a generator, which is easy to assemble and disassemble.

Background

Generating set has a lot now on the market, and the overwhelming majority is awl axle generator and awl axle engine lug connection, uses a stay bolt to pass whole generator shaft, and the engine axle head has the screw hole, and the stay bolt is twisted into the screw hole to make the conical surface of generator awl axle and engine awl axle slowly mesh, until producing elastic deformation, tightly embrace together, rely on the frictional force that elastic deformation produced to let the diaxon rotate together. This kind of structure, difficult dismantlement between two conical shafts, when generating set goes wrong, can't take apart generator and engine easily, need use special frock to assist and dismantle, the process is more loaded down with trivial details.

Disclosure of Invention

The invention aims to solve the technical problem of providing an easily-disassembled engine and generator connecting structure which is simple in structure and can realize the disassembly and the assembly of a generator and an engine without a special auxiliary tool. The invention is realized by the following technical scheme:

the utility model provides an easy dismouting engine and generator connection structure, its generator conical shaft rear portion is equipped with the bolt hole of stepping down, and the front end is equipped with the taper hole, and engine conical shaft tip center is equipped with the screw hole, taper hole and the cooperation of engine conical shaft outer wall, the bolt hole of stepping down department wears to be equipped with the stay bolt, and the rear portion of stay bolt has the nut at the outer fixed mounting of generator conical shaft, and the stay bolt front portion is fixed and is equipped with the boss, and the diameter of boss is greater than the aperture of engine conical shaft screw hole and the aperture of generator conical shaft bolt hole of stepping down.

Preferably, the nut and the long bolt are fixed through thread fastening glue.

Preferably, the long bolt is provided with external threads at the rear end part and the front part of the boss.

Advantageous effects of the invention

The utility model provides an easy dismouting engine and generator connection structure, can make engine and generator dismouting simple and easy, the maintainability is more simple and convenient, and is more swift, and whole dismouting process only needs a spanner just can be accomplished. Need not to use special auxiliary fixtures, the economic nature is better.

in the figure, 1, an engine conical shaft, 2, a threaded hole, 3, a generator conical shaft, 4, a long bolt, 5, a nut, 6, a bolt abdicating hole, 7, a boss, 8, a conical hole and 9, an external thread are arranged.

Detailed Description

The utility model provides an easy dismouting engine and generator connection structure, its 3 rear portions of generator conical shaft are equipped with the bolt hole 6 of stepping down, and the front end is equipped with the taper hole 8, and 1 tip center of engine conical shaft is equipped with screw hole 2, taper hole and the cooperation of engine conical shaft outer wall, the bolt hole of stepping down department wear to be equipped with stay bolt 4, and the rear portion of stay bolt has nut 5 at the outer fixed mounting of generator conical shaft, and the stay bolt front portion is fixed and is equipped with boss 7, and the diameter of boss is greater than the aperture of engine conical shaft screw hole and the aperture of generator conical shaft bolt hole of stepping down.

Optimized, the nut and the long bolt are fixed through thread fastening glue, so that the fixation is more convenient, and the disassembly and the assembly are convenient.

Optimally, the long bolt is provided with external threads 9 at the rear end part and the front part of the boss, so that the long bolt is convenient to process.

According to the connecting structure of the engine and the generator, which is easy to disassemble and assemble, which is protected by the invention, the two ends of the long bolt are provided with the threads, and the end close to the engine shaft is provided with the boss structure. During installation, the long bolt is firstly plugged into the generator conical shaft, then the locking nut and the tail of the long bolt are firmly fixed by using the thread fastening glue, the locking nut is rotated, the locking nut extrudes the generator conical shaft to move forward towards the end of the engine, and the boss of the long bolt abuts against the front end of the engine conical shaft, so that the engine conical shaft and the generator conical shaft are tightly held. When the locking nut is rotated in the opposite direction during disassembly, the boss of the long bolt can move outwards and move to the bolt abdicating hole to touch the inner end face of the generator conical shaft, the locking nut is continuously rotated, and the boss of the long bolt can extrude the inner end face of the generator conical shaft to enable the generator shaft to move outwards. After a moment of force is reached, the generator conical shaft and the engine conical shaft can be separated.

The diameter of boss is greater than the aperture of engine awl axle screw hole and the aperture of generator awl axle bolt hole of stepping down, makes the boss spacing when both easy to assemble, plays the effect of outwards pulling the generator awl axle again at the dismantlement formula.

In conclusion, the easily-detachable engine and generator connecting structure protected by the invention has a simple structure, and the generator and the engine can be detached without a special auxiliary tool.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
