Abstract
A connecting device of an output shaft of a gasoline engine water pump comprises the output shaft of the gasoline engine water pump and an impeller. The connecting device is characterized in that the outer wall of the output shaft is provided with a key groove, the impeller is provided with an installing hole, and a key is installed in the installing hole. The key is matched with the key groove, the middle of the output shaft is provided with a screw hole, and a bolt is installed in the screw hole. The bolt is in threaded match with the screw hole and tightly clamped with the impeller through the screw hole. The key groove is matched with the key in the installing hole of the impeller, the bolt is installed in the screw hole of the output shaft, and the impeller is fixed with the output shaft through the bolt and matched with the key through key groove. The connecting device of the output shaft of the gasoline engine water pump has the advantages that 1 processing is easy, mechanical strength is improved, and service life is prolonged; 2 the impeller is pushed into an output shaft of a gasoline engine, fixed through a bolt and added with corresponding parts so as to be used for the water pump; 3 the improved output shaft is pushed into a corresponding belt pulley, and gasoline engine power can also serve as motive power to be connected with other parts and drag the other parts to run, thereby being good in popularity and multipurpose in one machine.
Description
Technical field
The utility model relates to petrol engine water pump output shaft, particularly relates to the connection set of petrol engine water pump output shaft.
Background technique
The output shaft of existing petrol engine water pump is to be shaped on outside thread at outer wall mostly; Inwall at the impeller mounting hole is shaped on internal thread; Output shaft and impeller are through being threaded, and the shortcoming that this Placement exists is: 1, if when the power that the output shaft impeller is rotated is big, occur stripped thread easily; Even phenomenon such as fracture, transmission capacity and intensity difference; 2, process, make trouble, operation is many; 3, if output shaft is driven belt pulley when running, can not be general, versatility is poor.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of transmission capacity good, and intensity is high, easy processing, and versatility is good, the connection set of the petrol engine water pump output shaft of a tractor serves several purposes.
The technological scheme of the connection set of the utility model petrol engine water pump output shaft is: comprise the output shaft and the impeller of petrol engine water pump, it is characterized in that said output shaft outer wall has keyway, is shaped on mounting hole in impeller; Fitting key in the mounting hole; Key matches with keyway, opens screw in the centre of output shaft, construction bolt in the screw; Bolt and screw screw-thread fit, bolt tightens with impeller through screw mutually.
The utility model discloses a kind of connection set of petrol engine water pump output shaft, the keyway of output shaft outer wall is cooperated with key in the impeller mounting hole, again construction bolt in the screw of output shaft; Impeller fixes through bolt and output shaft; Cooperate with key through keyway, 1, easy processing, mechanical strength is improved; Frangible does not increase working life; The impeller that 2, will improve the back axis hole pushes the output shaft (axle on put into strong) of petrol engine, use bolt, and refilling originally, other corresponding component just can be used as the water pump use; 3, the output shaft (putting into strong on the axle) after will improving pushes corresponding belt pulley, and this petrol engine power can be used as motive force again and is flexible coupling through v belt and drags other parts running, and versatility is good, a tractor serves several purposes.
Description of drawings
Fig. 1 is the structural representation of the connection set of the utility model petrol engine water pump output shaft;
Fig. 2 is the structural representation of petrol engine water pump output shaft.
Embodiment
The utility model relates to a kind of connection set of petrol engine water pump output shaft, shown in Fig. 1-2, comprises the output shaft 1 and impeller 2 of petrol engine water pump; It is characterized in that said output shaft 1 outer wall has keyway 11, in impeller 2, be shaped on mounting hole 21, fitting key 4 in the mounting hole; Key matches with keyway, opens screw 12 in the centre of output shaft, and construction bolt 3 in the screw; Bolt and screw screw-thread fit, bolt tightens with impeller 2 through screw mutually.The keyway 11 of output shaft 1 outer wall is cooperated with key 4 in the impeller mounting hole 21, construction bolt 3 in the screw 12 of output shaft 1 again, impeller 2 fixes through bolt 3 and output shaft 1; Cooperate with key 4 through keyway 11,1, easy processing, mechanical strength is improved; Frangible does not increase working life; The impeller 2 that 2, will improve the back axis hole pushes the output shaft 1 (axle on put into strong 4) of petrol engine, and fixing with bolt 3, refilling originally, other corresponding component just can be used as the water pump use; 3, the output shaft 1 after will improving (putting into strong 4 on the axle) pushes corresponding belt pulley, and this petrol engine power can be used as motive force again and is flexible coupling through v belt and drags other parts running, and versatility is good, a tractor serves several purposes.
