Abstract

The invention relates to mechanical engineering, namely, devices for supplying grease from transport packaging to consumers. The purpose of the invention is to improve the mechanization and quality of unloading greases from transport packaging. The housing of the pump unit consists of a flange 1 with hollow projections 18 and a disk 2, in which body The pairs of gears 7, 8, and 9 are mounted; 10 The drive gears 8 and 9 are connected through a single worm pair to the drive 3, and another worm gear to a crank. Articulated with the last connecting rod mounted on the flange 1 The unit is lowered into the barrel with grease, the drive 3 is turned on, the disk 2 begins to turn slowly one way, then the other relative to the flange 1, and the gears, quickly rotating, grab the grease and serve it into the pressure line 6. As the grease is pumped from the barrel, the unit is lowered down. After completion of the operation, the pump unit is removed from the barrel 4 sludge.

The invention relates to mechanical engineering, and more specifically to devices for supplying grease from a transport container to silos of lubricating systems or installations for putting grease into bearings.

Known pump unit for supplying grease, containing the Executive body mounted on a disk placed in the hole of the flange, the outer diameter of which is made according to the size of the internal cavity of the container, the actuator of the Executive body having a discharge cavity connected to the discharge line.

A disadvantage of the known device is the low level of mechanization and quality of unloading lubricants from the shipping container.

The purpose of the invention is to improve the mechanization and quality of unloading lubricants from the shipping container.

The goal is achieved by the fact that a pump unit for supplying grease containing an actuator mounted on a disk placed in the flange aperture, the outer diameter of which is made according to the size of the internal cavity of the container, actuator of the actuator having injection cavities connected to the injection the main line is equipped with a crank mechanism, kinematically connected with the drive, the disk is mounted for rotation in the hole of the flange, in the body of the disk are pairwise articulated cylindrical cavities connected by the upper border of the articulation with the injection cavity, the actuator is made in the form of coupled gear pairs mounted for rotation s of the cylindrical cavities of the disk, the actuator communicates with the actuator one of each pair of gears, npvi this crank mechanism is mounted me disk, and the connecting rod is installed on the flange.

FIG. 1 shows a pump unit, axial section; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. 2

The pump unit for supplying grease contains a housing made of two main parts: flange 1 and disc 2, which is rotatably disposed in the annular groove of the first one.

The disk 2 has an actuator 3, which can be used as an electric motor or air motor of rotation. In the body of the disk are made in pairs articulated between themselves, open

From the bottom, towards the transport container cavity, there are cylindrical cavities and pressure cavities 4 connected to the upper border of their articulation, which are connected by a channel 5 with a supply line 6. In the cylindrical cavities of the disk 2, by analogy with a gear pump, a pair of gears 7, 8 and 9, 10, of which the drive gears 8 and 9 are connected by means of worm gears 11 and 12 and 13 and 12 to the drive shaft 3. The other end of the gear shaft 8 is connected to another crank 16, which is installed in bearing unit disk 2. Hinge but mounted on the flange 1, the connecting rod 17 forms a connecting rod-crank mechanism with the crank 16. On the side of the lower end of the flange 1 are hollow protrusions 18, which increase the buoyancy of the station on the surface of the lubricant in the transport container and at the same time prevent the rotation of the flange relative to the latter.

The pump unit works as follows

Using a lifting mechanism, the pump unit is lowered inside the shipping container, for example in a barrel with US-1 plastic grease or other lubricant with similar characteristics. The housing of the unit is placed in a container with a small gap relative to the wall and, due to its weight, is partially pressed into the lubricant medium. Gearbox 7 is turned on. Gears 7. 8 and 9, 10 receive a fast rotation from the screw 12, take lubricant with their teeth, transfer it to the pressure cavities 4 and, engaging with each other, squeeze the lubricant into the latter. From the pressure cavities 4 through the channels 5, the lubricant enters the pressure line 6 and further to the consumers. Simultaneously with the rotation of the gears from the worm gear pair 14, 15, the crank 16 acquires a slow rotation, causing alternate rotation in one direction or the other of the disk 8 s gears relative to flange 1 and, therefore, shipping containers. As the grease is pumped out of the container, the pump unit will go down until it reaches the bottom 18 by projections. To stop the transfer of lubricant, it is necessary to turn off drive 3. After completion of work, the pump unit is removed from the tare cavity with a lifting mechanism. The remaining lubricant on the tank walls after warming up the tank may be transferred to another similar container.

Thus, the proposed device allows to mechanize the time-consuming operation of filling machines and mechanisms with grease, eliminates unattractive manual labor, increases its culture, and saves grease up to 15-20% due to reduction of losses.
