Abstract
The invention relates to an oil pump of an engine, in particular to a leakage-free energy-saving oil pump capable of satisfying the requirement of using a belt transmission in case of insufficient space of the engine. The leakage-free energy-saving oil pump comprises a pump cover, a pump body, an outer rotor, an inner rotor, a rotor shaft and a belt wheel, and is characterized in that an oil baffle disc is additionally arranged at the inner side of the rotor shaft where the belt wheel is installed; the oil baffle disc is sleeved on the rotor shaft and is fixedly arranged on the belt wheel, and is fastened with an annular collecting groove on the pump body; both the pump body and the pump cover are provided with oil returning holes which are communicated with the annular collecting groove; and the oil returning hole of the pump cover is communicated with an oil tank. The leakage-free energy-saving oil pump has the advantages that the problem of oil leakage of the oil pump is thoroughly solved because the bowl-shaped oil baffle disc is skilfully matched with the annular collecting groove on the pump body as well as the oil returning holes on the pump body and the pump cover, and meanwhile, the structure that a mounting hole on the bowl-shaped oil baffle disc is fixed on the belt wheel through a screw; in addition, the structure also provides a new way to design the oil pump; the leakage-free energy-saving oil pump not only saves the oil but remarkably prolongs the service life.
Description
Technical field
The present invention relates to engine oil pump, particularly can meet motor insufficient space and use bel-drivenn No leakage energy-saving oil pump.
Background technique
Oil pump in the past, the parts that gear pump or rotor pump are all to provide engine lubricating oil, and the hard nut to crack all existed from machine oil pump shaft rotary part oil impregnate, if do not have oil impregnate, machine oil pump shaft can not be lubricated, and there is the hidden danger of oil pump seize.In order to prevent the machine oil of seepage from producing pollution to motor, under normal circumstances, oil pump is made built-in, makes the machine oil of seepage flow back in engine oil tank; A kind of situation is also had to be that oil pump is made outlet structure, its kind of drive adopts gear transmission or sprocket driving, there is a cover to pay cover by gear transmission simultaneously, machine oil is not allowed to outflow, but this structure to adopt bel-drivenn, because the machine oil that oil pump is oozed out can pollute belt, cause belt slippage, affect the normal work of oil pump; If adopt oil pump to add the method for oil sealing, due to the lubricating requirement of oil seal lip, also unavoidably have some lubricating oil leakages out, there is aging problem in the rubber of oil sealing simultaneously, affects the working life of oil pump.In order to compression engine structure, a kind of new work engine of the U.S. excellent magnificent Louth company designs, eliminate common from belt transmission to gear-driven secondary drive method, and employing directly uses belt pulley as the structure of oil pump upper driving power, so just oil pump oil leakage problem is had higher requirement.Through retrieval, energy-saving oil pump only has a utility model patent open, and application number is 201120385574.7, and Authorization Notice No. is CN202301011U, and authorized announcement date is 2012.07.04.Innovative point is between the pump housing and the junction plane of pump cover, be provided with the oily passage of mistake enclosed in rotor periphery.Present patent application innovative point is completely different from it.
Summary of the invention
The object of the invention is for above-mentioned defect, provide one can meet motor insufficient space and use bel-drivenn No leakage energy-saving oil pump.
Technological scheme of the present invention is No leakage energy-saving oil pump, comprise pump cover 1, the pump housing 2, external rotor 3, internal rotor 4, rotor shaft 6 and belt pulley 8, inside this side that it is characterized in that described rotor shaft 6 is installed belt pulley 8, oil baffle disc 5 is also installed, this oil baffle disc 5 is sleeved on rotor shaft 6 and is fixedly mounted on belt pulley 8, and is interlocked with annular collection trough on the pump housing 2; The pump housing 2 is provided with spill port 7, annular collection trough is connected with spill port 7, and pump cover 1 is also provided with spill port 9, and pump housing spill port 7 is connected with pump cover spill port 9, and pump cover spill port 9 is communicated with fuel tank.
Described oil baffle disc 5 is bowl shape, and is fixedly connected with belt pulley 8 with screw; Spill port 7 and spill port 9 are all arranged on the bottom of the pump housing 2 and pump cover 1.
Described oil baffle disc 5 also can be fixed on rotor shaft 6.
The present invention is at motor insufficient space, oil pump length direction does not allow to increase, under namely can not adding the prerequisite of oil sealing, ooze out to prevent machine oil, novelty improvement is carried out to oil pump, the oil pump pump housing is provided with one and collects the annular collection trough of machine oil, be communicated with the spill port on pump cover at a bottom design spill port of annular collection trough, lead to fuel tank with oil pipe again to add, recycle; On machine oil pump shaft, add a bowl-type oil baffle disc simultaneously, machine oil oil pump oozed out is got rid of by the centrifugal force of oil baffle disc to be got back in the annular collection trough of the pump housing, flow in fuel tank through spill port again, not only recycle but also reduce the waste of machine oil, through operation examination on site, the effect of sealing is better than the structure adding oil sealing
Advantage of the present invention is because bowl-type oil baffle disc coordinates with the ingenious of spill port on annular collection trough on the pump housing and pump housing pump cover, when motor insufficient space, thoroughly solves oil pump oil leakage problem.Meanwhile, bowl-type oil baffle disc has mounting hole be screwed over pulleys carried, this structure is also for oil pump design opens new road.Not only machine oil saving, and the working life significantly improving oil pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of bowl-type oil baffle disc.
In figure: 1-pump cover, the 2-pump housing, 3-external rotor, 4-internal rotor, 5-bowl-type oil baffle disc, 6-rotor shaft, 7-pump housing spill port, 8-belt pulley, 9 pump cover spill ports.
Embodiment
Embodiment is further illustrated in a preferred way below in conjunction with accompanying drawing.
With reference to Fig. 1 and Fig. 2, innovative point of the present invention be belt pulley 8 is installed on rotor shaft 6 this side inside oil baffle disc 5 is also installed, this oil baffle disc 5 is sleeved on rotor shaft 6 and is fixedly mounted on belt pulley 8, and is interlocked with annular collection trough on the pump housing 2; The pump housing 2 is provided with spill port 7, annular collection trough is connected with spill port 7, and pump cover 1 is also provided with spill port 9, and pump housing spill port 7 is connected with pump cover spill port 9, and pump cover spill port 9 is communicated with fuel tank; Oil baffle disc 5 is bowl shape, and is fixedly connected with belt pulley 8 with screw; Spill port 7 and spill port 9 are all arranged on the bottom of the pump housing 2 and pump cover 1; Oil baffle disc 5 also can be fixed on rotor shaft 6.
Belt pulley 8 is arranged on rotor shaft 6, makes internal rotor 4 drive external rotor 3 to rotate, complete the fuel feeding work of oil pump by the transmission of belt.Under the effect of high pressure oil, some machine oil will inevitably be oozed out from rotor shaft 6 and the gap of the pump housing 2, along axial flow to bowl-type oil baffle disc 5, collected by it, because bowl-type oil baffle disc 5 rotates together with belt pulley 8, these machine oil be collected then can be thrown in the annular collection trough on the pump housing 2 by bowl-type oil baffle disc 5, then the spill port 7 flowed on the pump housing 2 goes in fuel tank with the spill port 9 on pump cover 1.Thus ensure that machine oil can not ooze out pollution belt, and it also avoid the waste of machine oil.The pump housing 2 is positioned at that this one end of belt pulley 8 to be provided with annular collection trough be that machine oil for the ease of getting rid of flows into groove, and flows in spill port.
Bowl-type oil baffle disc 5 also can directly be fixed on rotor shaft 6, but bowl-type gear oil pump 5 to be fixedly mounted on belt pulley 8 be optimum scheme.
