Abstract
The invention relates to a cylinder average oil supplier, which is formed by cylinder (1), oil baffle plate (4), total oil inlet (5), oil outlet (7), gear (3) and axle (2), wherein the invention is characterized in that: the side plates (10) at two ends of sealing cylinder (1) are mounted with two parallel axles; the oil baffle plate (4) divides the cylinder (1) into several oil chambers (8), while each oil chamber comprises that said axles (2) are fixed with a couple of meshed gears (3); the oil outlet and inlet (7, 9) are arranged above and under the oil chambers (8). The invention has several oil outlets with equal oil pressure and same speed, but only one oil inlet, to keep consistent motion between several working cylinders, with stable operation. The invention can be used in the hydraulic transmission system.
Description
Technical field
The invention belongs to hydraulic transmission technology field, specifically have a plurality of oil supplying devices that wait the oil outlet of oil pressure and uniform flow and have only a filler opening.
Background technique
The mode of movement of pressure oil is in the fluid drive mechanism that provides in the market: oil hydraulic pump has the liquid of certain pressure by supercharging output, oil outlet at oil hydraulic pump connects one or more pressure tubes then, pressure tube is transferred to pressure oil respectively in each operating cylinder, and each operating cylinder will carry out pressure output according to suffered oil pressure by piston, piston rod and oil inlet and outlet; Body dumping mechanism in existing dumping car, an engineering loading-unloading vehicle operating cylinder commonly used to rise from dump bucket, down maneuver, the operating oil pressure of such operating cylinder is big, the oil cylinder volume is big, the floor compartment structural strength is required high, it is big to take up room, promote the car load height of wagon, thereby reduced useful load; Body dumping mechanism in existing dumping car is also used the hydraulic work pump and is connected a plurality of identical operating cylinders, the piston rod of a plurality of operating cylinders is simultaneously to rising from dump bucket, down maneuver, because the motion state of each operating cylinder piston rod is relevant with the pressure of extraneous goods weight that is subjected to and pressure oil, and the be under pressure pressure of oil of each operating cylinder equates, when if the extraneous goods weight that each operating cylinder is subjected to equates, the flow velocity of the oil inlet and outlet of each operating cylinder equates, the motion state of each operating cylinder piston rod is consistent, when if the extraneous goods weight that each operating cylinder is subjected to is unequal, the flow velocity of the oil inlet and outlet of each operating cylinder does not equate, the motion state of each operating cylinder piston rod will be consistent so, at this moment the compartment appears and body frame twists mutually, uneven, even can may overturn, damage machinery.
Summary of the invention
Device for even oil supply for oil cylinder of the present invention, be used between oil hydraulic pump and the operating cylinder, the flow velocity that the present invention can make oil feeder export each branch road oil pressure and oil equates, with the irrelevant oil feeder of the suffered external force of operating cylinder piston rod, device for even oil supply for oil cylinder is used between hydraulic workstation and the operating cylinder, make each outlet oil pressure of oil feeder and the flow velocity of oil remain unanimity, and it is irrelevant with the suffered external force of operating cylinder piston size, thereby each operating cylinder piston is remained to be synchronized with the movement, thereby solved effectively because the deficiency that does not have device for even oil supply for oil cylinder to cause in the existing hydraulic mechanism, solved simultaneously when the heavy wool cylinder is simultaneously to same loaded work piece in the fluid drive mechanism, the motion of the piston rod of each oil cylinder may the inconsistent harm that causes.
The present invention is achieved in that device for even oil supply for oil cylinder, mainly form by oil pocket, oil separating plate, gear and axle, it is characterized in that: two axles 2 that are parallel to each other are installed on the side plate 10 at sealed cylinder 1 two ends, oil separating plate 4 is separated into a plurality of oil pockets 8 with oil cylinder 1, the structure of each oil pocket 8 is: be fixed with a pair of pitch wheel 3 at described two axles that are parallel to each other on 2, be respectively equipped with oil outlet 7 and filler opening 9 at the upper and lower of oil pocket 8; Below a plurality of filler openings 9, be provided with fuel reserve tank 6, below fuel reserve tank 6, be provided with total filler opening 5; Oil separating plate 4 can be separated into oil cylinder 14 oil pockets 8; Oil separating plate 4 also can be separated into oil cylinder 12 oil pockets 8; The profile of oil pocket 8 is cylindrical, square or other geometrical shape in the sealed cylinder 1.
Compare with existing oil feeder, fuel tank device for even oil supply provided by the invention, adopt many groups oil pocket of coaxial connection, in every group of oil pocket a pair of pitch wheel is arranged all, make and respectively organize meshed gears and rotate and to be consistent, thereby make the oil pressure of each oil pocket oil outlet and the flow velocity of oil remain consistently, make the pressure oil average mark that enters the fuel tank device for even oil supply be made into a plurality of have identical oil pressure and flow velocity branch roads like this.
Compared following beneficial effect with existing dumping car hydraulic pressure self-discharging system:
1, under the equally loaded situation, the operating oil pressure of operating cylinder is little, and the oil cylinder volume is little, and low to the requirement of platform floor structural strength, it is little to take up room, and has reduced the car load height of wagon, thereby has increased useful load;
2, can not occur twisting mutually because of the inconsistent compartment that causes of each operating cylinder piston rod movement and vehicle frame, imbalance has improved the stability of car load when the self-unloading goods, the working life of having improved dumping car.
