Abstract
The utility model provides a floating pin roller which converts the sliding friction of an end into rolling friction at the end of a sliding vane of a fixed sliding vane pump. Because the pin roller rotates in a floating mode between an inner hole at the end of the sliding vane and a mandrel, friction loss is greatly decreased, the life time and the reliability of the utility model are improved, and therefore, the utility model becomes a pump with competitive power in the field of a displacement pump with larger discharge.
Description
One, technical field
The utility model relates to a kind of Roller sliding-vane pump that adopts fixed pattern vane motion mechanism to make displacement pump, especially decides the Roller sliding-vane pump that the design of slide plate end has the floating roller.
Two, background technique
As everyone knows, fixed pattern vane motion mechanism mainly is made up of reciprocating fixed pattern slide plate, eccentric rotor, spring and the pump housing.The application of deciding the sliding sheet volume pump of current employing fixed pattern vane motion mechanism can only be confined in the category of little discharge capacity, because big discharge capacity requires slide plate that big stroke is arranged, perhaps uses high rotating speed.Big stroke and high slide plate reciprocating frequence, the friction that makes slide plate end and eccentric rotor be in contact with one another part increases, wearing and tearing increase severely, life-span and reliability are just poor, compare with the rotary sheet type displacement pump of slide plate rotation, though do not have frictional loss between pump housing endoporus and eccentric rotor, do not have great competitive ability on the whole.
Three, summary of the invention
The purpose of this utility model is the slide plate that there is the floating roller construction a kind of end of design, the sliding friction that makes slide plate end and eccentric rotor be in contact with one another part becomes rolling friction, thereby reduced friction and wear significantly, make that to decide the sliding sheet volume pump not only simple in structure, and the life-span is long, good reliability, becomes the strong displacement pump of competitive ability on the whole.
The purpose of this utility model is achieved in that places the floating roller have axle in the slide plate end, the floating roller is under the friction of eccentric rotor drives, and floating ground rotates in the hole of slide plate end and the lubricant oil in two annular spaces of axle.Though the rotating speed of floating roller is higher, because the oil film protection is arranged, the life-span is very long, reliability is fine.
Four, description of drawings
Fig. 1 is the schematic representation of Roller sliding-vane pump.
1. pump housings, 2. eccentric rotors, 3. slide plates, 4. floating rollers, 5. axles, 6. springs among the figure
Five, embodiment
There is an endoporus end of slide plate 3, places floating roller 4 and axle 5 in the endoporus, and the external diameter of the endoporus of floating roller 4 and axle 5 is slidingly matched, and center roller 5, floating roller 4 are its bearings; The cylindrical of floating roller 4 is slidingly matched with the end endoporus of slide plate 3 again, floating roller 4 is again an axle to this endoporus, in other words, floating roller 4 is that floating ground rotates in the lubricant oil of two annular spaces between the endoporus of the cylindrical of axle 5 and slide plate 3 ends, obtains splendid life-span and reliability.
Can be in the endoporus of slide plate 3 ends for simplifying the internal structure of an organization also, only to put into floating roller 4 and do not put into axle 5,4 of floating rollers rotate in the lubricant oil of an annular space.
Claims (2)
1. one kind mainly by the Roller sliding-vane pump that has floating roller, axle, decides slide plate, the pump housing, eccentric rotor, spring are formed, it is characterized in that: there is an endoporus slide plate end, place the axle that is with the floating roller in the endoporus, floating roller external diameter and slide plate end endoporus are slidingly matched, and floating roller endoporus and axle external diameter are slidingly matched.
2. Roller sliding-vane pump according to claim 1 is characterized in that: have only the floating roller in the end endoporus of slide plate.
