Abstract
A loader-digger digging swing arm hinged lubricating device comprises a pivoting supporting base, swing arms and a hinge pin. The end portions of the swing arms are internally arranged in the pivoting supporting base, and are hinged with the pivoting supporting base through the hinge pin. The swing arms comprise swing arm bodies and sleeves which are fixedly installed at the end portions of the swing arm bodies, shaft sleeves are arranged between the sleeves and the hinge pin, the shaft sleeves are respectively located at two ends of the sleeves, the sleeves, the hinge pin and the shaft sleeves form an annular cylindrical cavity, an oil cup which is used for filling lubricating grease is arranged on the side faces of the sleeves, and the oil cup is communicated with the annular cylindrical cavity. The loader-digger digging swing arm hinged lubricating device only adopts one lubricating point, maintenance and operation are convenient, meanwhile, the annular cylindrical cavity which is used for storing the lubricating grease is formed in the middle of the device, abrasion is reduced, working effective time is prolonged, no hole needs to be formed in the hinge pin, strength of the hinge pin is higher than that of a hinge pin with a hole, wherein the diameters of the two hinge pins are the same, structure is compact, and cost is low.
Description
Technical field
The utility model relates to a kind of hinged lubricating arrangement of construction machinery product swing arm, and particularly a kind of loader-digger excavates the hinged lubricating arrangement of swing arm, belongs to technical field of engineering machinery.
Background technology
The loader-digger front and back end is respectively load terminal and excavates end, and a same complete machine can realize loading and excavating function, therefore is commonly called as to be " two is busy ".
The excavation swing arm of loader-digger is connected with the complete machine vehicle frame by pivoting support.The type of attachment of excavating swing arm and pivoting support at present is respectively that swing arm parcel pivoting support and pivoting support wrap up two kinds of swing arms.The structure of swing arm parcel pivoting support adopts the both sides swing arm lubricated, unlubricated lubricating system in the middle part of the pivoting support, and there are two oil sites in this lubricating system, and oil storage is insufficient, needs often to safeguard and maintenance point problem how; The structure of pivoting support parcel swing arm is the biside plate articulated form of swing arm, in separated, bearing pin perforate one side is lubricated, it is lubricated that the lubricating system of this structure need axially be opened lubrication hole or the axle sleeve perforate of swing arm both sides at bearing pin, the intensity of bearing pin own is weakened, and needs to strengthen pin diameter, and cost increases, and oil storage capacity is weak, needs often to add butter.
Summary of the invention
Goal of the invention: the utility model provides a kind of easy to maintenance, compact conformation, loader-digger simple and reliable for structure to excavate the hinged lubricating arrangement of swing arm.
Technical scheme: a kind of loader-digger excavates the hinged lubricating arrangement of swing arm, comprise pivoting support, swing arm and bearing pin, it is interior and hinged by bearing pin and pivoting support that described swing arm end is built in pivoting support, described swing arm comprises the swing arm body and is fixedly mounted on the sleeve of swing arm body end, be provided with axle sleeve between described sleeve and the bearing pin, described axle sleeve lays respectively at the sleeve two ends, and described sleeve, bearing pin and axle sleeve form the circular cylindrical cavity; The side of described sleeve is provided with the lubricating cup for grease up, and described lubricating cup is communicated with the circular cylindrical cavity.Lubricating grease is filled in the circular cylindrical cavity by lubricating cup, and the disposable more lubricating grease of can annotating can prolong maintenance period.
For the junction between better lubricated swing arm and the pivoting support, described axle sleeve inside is provided with annular oil groove, and described oil groove is communicated with the circular cylindrical cavity.Lubricating grease enters junction between axle sleeve and the bearing pin by oil groove, lubricates the application life that has prolonged bearing pin and axle sleeve effectively.
Excessive in order to prevent the lubricating grease in the axle sleeve, the described axle sleeve outside is respectively equipped with the oil sealing that is installed between sleeve and the bearing pin.Can lubricate more effectively, prevent from that lubricating grease is excessive to cause waste and influence the complete machine outward appearance, avoid the pollution of environment.
Beneficial effect: the utility model only adopts an oil site, maintains easily operation, and the middle part is useful on the circular cylindrical cavity that stores lubricating grease simultaneously, reduce wear, prolong work effective time, bearing pin need not perforate simultaneously, the bearing pin of strength ratio perforate equivalent diameter is big, compact conformation, and cost reduces.
Description of drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is three-dimensional view of the present utility model.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As illustrated in fig. 1 and 2, a kind of loader-digger excavates the hinged lubricating arrangement of swing arm, comprise pivoting support 1, swing arm 2 and bearing pin 3, it is interior and hinged by bearing pin 3 and pivoting support 1 that described swing arm 2 ends are built in pivoting support 1, described swing arm 2 comprises swing arm body 21 and is fixedly mounted on the sleeve 22 of swing arm body 21 ends, be provided with axle sleeve 4 between described sleeve 22 and the bearing pin 3, described axle sleeve 4 lays respectively at sleeve 22 two ends, and described sleeve 22, bearing pin 3 and axle sleeve 4 form the circular cylindrical cavity; The side of described sleeve 22 is provided with the lubricating cup 5 for grease up, and described lubricating cup 5 is communicated with the circular cylindrical cavity.Lubricating grease is filled in the circular cylindrical cavity by lubricating cup 5, and the disposable more lubricating grease of can annotating can prolong maintenance period.
For the junction between better lubricated swing arm 2 and the pivoting support 1, described axle sleeve 4 inside are provided with annular oil groove 41, and described oil groove 41 is communicated with the circular cylindrical cavity.Lubricating grease enters junction between axle sleeve 4 and the bearing pin 3 by oil groove 41, lubricates the application life that has prolonged bearing pin 3 and axle sleeve 4 effectively.
Excessive in order to prevent the lubricating grease in the axle sleeve 4, described axle sleeve 4 outsides are respectively equipped with the oil sealing 6 that is installed between sleeve 22 and the bearing pin 3.Can lubricate more effectively, prevent from that lubricating grease is excessive to cause waste and influence the complete machine outward appearance, avoid the pollution of environment.
