Abstract
The utility model provides a hydraulic pump transmission mechanism of a vertical single-cylinder diesel engine, which comprises a transmission shaft and a transmission gear. The transmission shaft is mounted in a shaft hole of a gear chamber cover of a diesel engine, the transmission gear mounted at the inner end of the transmission shaft is meshed with a cam shaft gear of the diesel engine, and the outer end of the transmission shaft is connected with a connection shaft of a hydraulic pump. Speed ration of the transmission gear to the cam shaft gear is 3.5 to 4.5: 1. At work, the transmission gear is driven by the cam shaft gear meshed therewith so as to drive the transmission shaft to rotate, thereby leading the connection shaft of the hydraulic pump connected with the outer end of the transmission shaft to rotate and realizing operation of the hydraulic pump. The hydraulic pump transmission mechanism has reasonable and compact structure, short transmission path, high transmission efficiency and strong working reliability without affecting original functions of the diesel engine, and is particularly adaptable to use with a tractor.
Description
Technical field
The utility model relates to the oil hydraulic pump driving mechanism of a kind of driving mechanism of diesel engine, particularly a kind of vertical type single-cylinder diesel engine.
Background technique
Vertical type single-cylinder diesel engine is used to drive the hydraulic pump works of hydraulic actuator because the use field needs the power output of a part usually.At present, the hydraulic pump drive mechanism of vertical type single-cylinder diesel engine is generally the bel-drivenn structural formula, there is that transmission efficiency is low, when the deficiency of poor reliability, particularly vertical type single-cylinder diesel engine are used on the tractor, also exist and easily bump impaired shortcoming in structural configuration difficulty, the using process.
The model utility content
For overcoming the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, transmission efficiency is high, the oil hydraulic pump driving mechanism of the vertical type single-cylinder diesel engine of good reliability, is particularly suitable for the supporting use with tractor.
The technological scheme that its technical problem that solves the utility model adopts is: comprise transmission shaft and driving gear; Described transmission shaft is installed in the axis hole of gear chamber cover of diesel engine, and driving gear is loaded on the inner of transmission shaft, and is meshed with the camshaft gear wheel of diesel engine; The outer end of transmission shaft is connected with the coupling shaft of oil hydraulic pump.
The velocity ratio of above-mentioned driving gear and camshaft gear wheel is 3.5～4.5: 1.
During work, driving gear is driven by the camshaft gear wheel that is meshed with it, rotates in the lump thereby drive transmission shaft, and the coupling shaft of the feasible oil hydraulic pump that is connected with the transmission shaft outer end rotates, and realizes the operation of oil hydraulic pump.
The beneficial effects of the utility model are: it is rational in infrastructure, compact, and drive path is short, transmission efficiency is high, functional reliability is strong, and does not influence the original function of diesel engine, is particularly suitable for the supporting use with tractor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that oil hydraulic pump, 1-1 are that coupling shaft, 2 is that crankshaft gear, 3 is that camshaft gear wheel, 4 is that gear chamber cover, 5 is that driving gear, 6 is that transmission shaft, 7 is that key, 8 is a bearing.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Driving mechanism described in the utility model comprises transmission shaft 6 and driving gear 5.Described transmission shaft 6 is installed in by bearing 8 in the axis hole of gear chamber cover 4 of diesel engine, driving gear 5 is fixedly mounted in the inner of transmission shaft 6 by key 7, and be meshed with the camshaft gear wheel 3 of diesel engine, driving gear 5 is 4: 1 with the velocity ratio of camshaft gear wheel 3; Camshaft gear wheel 3 is meshed with crankshaft gear 2.The outer end of transmission shaft 6 adopts notch Placement (or key Placement) to be connected with the coupling shaft 1-1 of oil hydraulic pump 1.
During work, the power of diesel engine passes to driving gear 5 by crankshaft gear 2 and camshaft gear wheel 3, rotates in the lump thereby drive transmission shaft 6, and the coupling shaft 1-1 of the feasible oil hydraulic pump 1 that is connected with transmission shaft 6 outer ends rotates, and realizes the operation of oil hydraulic pump 1.
