Description
Technical Field
The invention relates to the technical field of gasoline engines, in particular to a gasoline engine output structure for a water pump.
Background
The output structure of the traditional gasoline engine generally adopts two modes according to the difference of matched machines, one mode is that a flywheel is provided with a tension block, and the function of linkage with the machines is achieved through rotating speed clutch; the other is to directly connect the lengthened crankshaft with the machine to achieve the linkage function. The first mode is generally used in garden machinery for matching with a brush cutter, a mini-tiller, a ground auger and other complete machines, and the second mode is generally used in agricultural plant protection machinery for matching with a water pump and other machines. However, the second method is to lengthen the crankshaft, which causes a series of problems, in order to ensure the rigidity of the crankshaft, the shaft diameter needs to be thickened, and parts such as the crankshaft and the crankcase need to be redesigned, which increases the cost, in addition, the jumping value of the output end of the lengthened crankshaft is difficult to ensure, because the jumping value of the crankshaft is large, the water pump impeller and the crankshaft are easy to interfere with the water pump volute after being assembled, so that only the gap between the water pump impeller and the water pump volute can be increased, and the gap between the water pump impeller and the water pump volute is an important factor affecting the performance of the water pump, and the performance of the water pump is seriously affected by the method of lengthening the crankshaft.
Disclosure of Invention
The invention aims to provide an output structure of a gasoline engine for a water pump, which is used for improving the performance of the water pump and reducing the cost.
The technical scheme of the invention is as follows: the utility model provides a gasoline engine output structure for water pump, includes gasoline engine flywheel, gasoline engine fan casing, output shaft, its characterized in that: the output shaft is connected with a gasoline engine flywheel; an excircle positioning structure and a mounting disc are arranged at one end of the output shaft, the gasoline engine flywheel is provided with a central positioning hole and a mounting boss, the output shaft and the gasoline engine flywheel are radially positioned through the excircle positioning structure and the central positioning hole, and the output shaft and the gasoline engine flywheel are axially positioned through the mounting disc and the mounting boss; the gasoline engine fan cover is provided with a bearing, and the output shaft is connected with the gasoline engine fan cover through the bearing; the other end of the output shaft is connected with the water pump. The output shaft of the invention is fixedly connected with the flywheel of the gasoline engine through screws.
The invention has the beneficial effects that: compared with the traditional gasoline engine output structure for the water pump, the gasoline engine output structure for the water pump has the advantages that the output shaft is the half shaft, the rigidity and the coaxiality are better compared with a lengthened crankshaft, the fan cover is additionally provided with the bearing to support the output shaft, the jumping of the output shaft end can be greatly reduced, the optimal gap between the water pump impeller and the water pump volute is ensured, meanwhile, parts such as a crank case, a crank shaft and the like do not need to be additionally designed and manufactured, and the gasoline engine output structure for the water pump can be used for multiple purposes. The invention has simple operation and convenient use, ensures the performance of the water pump and saves the cost.
