Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1 and 2, a gas generator structurally comprises a generator body 1 and a combustion engine 2, wherein a circulating water pump 3 is mounted on the combustion engine 2, the circulating water pump 3 can drive a cooling liquid in a casing of the combustion engine 2 to circularly flow so as to achieve the purpose of cooling, and cooling liquid channels in the casings of the circulating water pump 3 and the combustion engine 2 are designed into the prior art and are not further described herein.

As shown in fig. 2, a first belt pulley 1a is disposed on the input rotating shaft of the generator body 1, a second belt pulley 2a is disposed on the power main shaft of the combustion engine 2, a third belt pulley 3a is disposed on the pump shaft of the circulating water pump 3, the first belt pulley 1a, the second belt pulley 2a and the third belt pulley 3a are jointly sleeved with a belt 4, and the belt 4 is used for driving the input rotating shaft of the generator body 1 and the pump shaft of the circulating water pump 3 to synchronously rotate along with the power main shaft of the combustion engine 2.

In the present embodiment, the end of the third pulley 3a is mounted with the fan 5 through the connecting member 6, and the diameter of the second pulley 2a is smaller than the diameter of the third pulley 3 a. When the gas generator operates, the second belt pulley 2a and the third belt pulley 3a form a speed reduction transmission relationship, so that the fan 5 can be ensured to operate at a lower rotating speed, and the generator assembly has lower operation noise. Besides, when facing to gas generators with different specification parameters, the rotating speed of the fan 5 can be adapted by adjusting the diameter combination of the second belt pulley 2a and the third belt pulley 3a, and the gas generator has the technical advantages of strong universality and good practicability.
