Description
Technical field
The present invention relates to method and device thereof that a kind of no matter retarder forward or reverse can both fuel feeding, can be widely used in the system that forward or reverse such as retarder and compressor all need to lubricate, belong to the gear pump technical field.
Background technique
Gear-worm type of reduction gearing is a deceleration machinery common in the mechanical industry, but because the restriction of lubricating condition, gear pair and worm and gear often can only adopt horizontal layout, gear and worm and gear adopt the oil sump flooding system lubrication, the lubrication effect of this lubricating system is poor, owing to adopt oil sump to soak into, the cooling effect of retarder is also poor simultaneously.
If adopt the retarder of vertical worm screw arrangement, adopt the oil sump infiltration in the retarder and drench the mode that oil lubrication combines, lubrication state must greatly take on a new look.Simultaneously, because lubricant oil constantly circulates in the case, radiating condition improves greatly, thereby can make the housing structure compact, and it is very good satisfying some special requirements.And conventional gear pump is helpless, as shown in Figure 1, gear pump is by planet wheel 4, star-wheel 5, oil groove and oil circuit are formed, when gear is rotated in the forward, lubricant oil is entered in the cavity that inside engaged gear forms by oil-feed tank, rotation along with gear, lubricant oil in the chamber is being with to going out oil groove 41 motions, in going out oil groove 41 scopes, along with gear is further rotated, planet wheel 4, the volume that star-wheel 5 forms diminishes gradually, until being zero, at this moment the lubricant oil in the chamber is squeezed, and behind the formation pressure, flows out from going out oil groove 41, if during the gear counterrotating, because planet wheel 4, the cavity that star-wheel 5 forms can't obtain oil from oil groove, can't push liquid, and is also not fuel-displaced with regard to pump.
Summary of the invention
The objective of the invention is to invent method and device thereof that a kind of no matter retarder forward or reverse can both fuel feeding.
For realizing above purpose, no matter the technical solution of the utility model provides the method that a kind of retarder forward or reverse can both fuel feeding, it is characterized in that, sense of rotation regardless of retarder, all, control the switching of fluid passage, flow thereby change fluid by pressure difference because of the different different direction that sense of rotation produced, make stream stream keep the single flow direction, its method is:
(1). when gear pump was rotated in the forward, the liquid of first oil groove entered in the cavity of internal gear pair formation, moves to second oil groove along with gear pair continues to be rotated in the forward, and the liquid of first oil groove constantly is moved out of, and formed negative pressure; The liquid of second oil groove constantly is extruded, form malleation, piston under pressure, move downward, at this moment first passage, second channel are opened, third channel, four-way are shut, and the flow direction of liquid is: outside-first passage-first oil groove-second oil groove-second channel-worm screw passage;
(2). when the gear pump counterrotating, the liquid of the 3rd oil groove enters in the cavity of internal gear pair formation, moves to the 4th oil groove, and along with gear pair continues counterrotating, the liquid of the 3rd oil groove constantly is moved out of, and forms negative pressure; The liquid of the 4th oil groove constantly is extruded, form malleation, piston under pressure, move upward, at this moment four-way, five-way road are opened, the 6th passage, first passage are shut, and the flow direction of liquid is: outside-four-way-the 3rd oil groove-the 4th oil groove-five-way road-worm screw passage.
A kind of no matter retarder forward or reverse can both fuel feeding the needed device of method, it is characterized in that, be to reverse gear pump, the described gear pump that reverses, comprise spring, the passage connected body, gland, planet wheel, star-wheel, driving sleeve, oil distribution casing, planet wheel and star-wheel are formed internal gear pair, driving sleeve places outside planet wheel and the star-wheel, in have the passage connected body of spring to place the upper end of driving sleeve, oil distribution casing is fixed in the lower end of driving sleeve, it is characterized in that be provided with a piston vertical with oil distribution casing in oil distribution casing, the oil groove of oil distribution casing and piston are formed four groups of oil grooves and passage.
The centre of described oil distribution casing is provided with the oil groove of two symmetries, is provided with a hole vertical with oil groove, that be complementary with the axle of piston on the cylinder of oil distribution casing.
Described piston is made up of axle and piston head, and piston head places the two ends of axle.
Described spring, passage connected body, gland, planet wheel, star-wheel, driving sleeve, oil distribution casing constitute vertical layout.
The present invention adopts and be provided with a piston vertical with oil distribution casing in oil distribution casing, the oil distribution casing partial fixing is motionless, by planet wheel in the driving sleeve driven gear pump and star-wheel motion, make pump obtain power, when driving sleeve rotates, the star-wheel and the planet wheel that drive internal gear pair rotate, the planet wheel of internal gear pair and the relative movement of star-wheel, make the liquid in the oil distribution casing produce pressure difference, thereby promoting piston moves in oil distribution casing, the sense of rotation that gear pump is different, promote piston and in oil distribution casing, move, form the structure of two position two-way valve, thereby the switching of control fluid passage and change fluid flow towards different directions, forward or reverse no matter, fluid all can go out from single orifice flow.
The utility model has the advantages that regardless of sense of rotation liquid stream is kept the single flow direction.
