Problems solved by technology
The cooling fan of the generator is set at the rear end of the engine and connected to the shaft sleeve concentrically connected between the generator and the engine crankshaft, and the generator fan is contained by the cooling air passage formed independently by the front cover of the generator, and cannot be connected with the crankcase at the rear end of the engine. The cover directly forms a closed cooling air channel, which cannot achieve the effect of cooling the engine lubricating oil at the same time
Since the front end cover of the generator forms an independent cooling air passage, it is necessary to install a sealing plate on the front end cover of the generator, which makes the structure appear complicated and not beautiful

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings:
[0025] like figure 1 As shown, the present invention mainly includes a crankcase 1, a crankcase cover 2, a crankshaft 3, a motor front end cover 4, a motor connecting sleeve 5, a cooling fan 6 and a generator 7, and one side of the crankcase 1 is connected to the crankcase cover 2 , the rear end of the crankcase cover 2 is connected to the motor front end cover 4 , and the rear end of the motor front end cover 4 is connected to the generator 7 .
[0026] The crankshaft 3 is installed in the crankcase 1 through the bearings at both ends, and one end of the crankshaft 3 extends through the crankcase cover 2 into the front end cover 4 of the motor. A cooling fan 6 that rotates with the crankshaft 3 is connected to the end of the crankshaft 3 in the motor front end cover 4 , a motor connecting sleeve 5 is arranged between the crankshaft 3 and the coolin...

The invention relates to a cooling structure of an engine and a generator and belongs to the technical field of cooling. The cooling structure is specifically used for cooling of the engine and the generator. The cooling structure comprises a crankcase cover and a motor front end cover. The side, connected with the motor front end cover, of the crankcase cover is provided with a crankcase cover flange end face, and the outer circle of the crankcase cover flange end face is provided with a crankcase cover cooling channel. The side, connected with the crankcase cover, of the motor front end cover is provided with a motor front end cover flange end face matched with the crankcase cover flange end face, and the outer circle of the motor front end cover flange end face is provided with a motor front end cover cooling channel matched with the crankcase cover cooling channel. The cooling structure achieves integration design between the crankcase cover and the motor front end cover, meanwhile, reduces the temperature of lubricating oil in a crankcase of the engine and the temperature of the generator, and enables the engine and the generator o work more reliably.
Description
technical field [0001] The invention relates to a cooling structure for an engine and a generator, in particular for cooling the engine and the generator, and belongs to the technical field of cooling. Background technique [0002] In the prior art, the cooling fan of the engine is arranged at the flywheel end of the engine. The cooling fan of the generator is arranged at the rear end of the engine and is connected to the shaft sleeve concentrically connecting the generator and the crankshaft of the engine, and the generator fan is contained by the cooling air duct formed independently by the front end cover of the generator, and cannot be connected with the crankcase at the rear end of the engine. The cover directly forms a closed cooling air channel, which cannot achieve the effect of cooling the engine oil at the same time. Since the front end cover of the generator forms an independent cooling air duct, it is necessary to install a sealing plate on the front end cover o...
