Devices for centralized lubrication of various types of machines are known by spraying the lubricant with the exhaust gases of the internal combustion engine of this machine. Such devices include

vane gas blower, gas distributor and ejection lubrication sprayers.

But; With the help of such devices, cases of dry friction in rubbing parts are not excluded. The proposed device, referring to the above: 1 described type and intended to lubricate the tractor's transmission, is free from this drawback.

The inventive nature of the invention lies in the fact that ion sprays are mounted in oil dans or crankcases of transmission assemblies, and their spray nozzles are directed at each crushing nai) y. The supply of exhaust gases to an aziomagnetate; it is carried out only when it starts up in o: i. In the gas pipelines to the ejection sprayers, a pulsating flow is created with an Nsoiiibio interface;

FIG. 2 - gas distribution in section (on an enlarged scale); in fig. 3-view of the ejection spray in the section.

The exhaust gases are sucked off by the gas pump / from the exhaust manifold 2 of the internal combustion engine and fed to the gas distribution chamber 3. The shaft 4 of the gas blower 1 receives vrah from gear 5 on the flywheel 6. planted on the crankshaft 7 of the engine of the machine.

In permanent engagement with gear 5, gear 8 is located on the clutch roller 9. Coupling 9 is activated by the clutch 9 by means of the lever 10. On the exhaust pipe 11 of the engine, a box 12 is mounted with two hinges installed by gas dampers 13.

Switching on the clutch and closing the wiper. 1 RANK is blocked so that when the clutch is turned on, the shutter closes. Pr; iod to the damper “about the ocyniecTBHTb lever and.ti automatic due to the pressure difference; ogmospho; 1Y and RrjbiX.ioiiiiOM 1; the collector at 1Gl, - the gas-girder trough;

From the gas distributing chamber 3, the gases are fed through gas pipelines 14 and 15 to ejection sprays 16, installed in oil / 7 onboard gears (side drive, to which the pelvis is fed through gas pipeline 14, according to the diagram of the show).

Gas pipeline 18 supplies gas to gearbox oil vap 19 and through gas pipeline 20 to central transmission eaiHine 21.

To arrange gas pressure in the gearbox housings, central gear and onboard gears, valves are installed.

The waste pipe from the pneumatics. The tube passes into the expansion of the cone forming the gas distribution chamber. There are four apertures on the Pig |) oCom of the base of the cone, connected to the discharge pipelines 14, 15, 8, 20, through which the spent 1ases are fed to the sprayers 16. The four holes in the base of the periodic cone are closed by a rotating rotary chopper 23 with a conical fairing 24. Valve shaft 25 is installed in the ball bearings and receives rotation through pinch 26 from the gas-igniter shaft.

The ejection nozzle 16 is a curved thin-walled steel tube 27, at the end of which at a desired angle and to the required height it is screwed to the tip 28. At the bottom of the wall there are inclined conical holes 29 through which the inner space of the sprayer communicates with the oil bath. Inside the tube 27 and the tip 28 in the center, in the supports 30 and 3L, a tube 32 is installed, both ends of which are connected to the level of oil in the bath. One tube is open, and on the other end there is a pressure reduction valve 33 installed.

The operation of the device proceeds in the following manner.

Before turning the transmission into operation (when starting the tractor) the lever 10 includes clutches

stsen.cheii .9. -icpes v. t 4 rotation is transmitted to the 1-charger 1. At the same time, the gas alarm / - closes. Under the nanometer, create. the gas charger, gases are fed to the gas distribution chamber -j. From the afterbirth, the gas to the OP crown. :: noTOKONt is fed to the spray gun lg. The pulsating movement of the gas in the outlet u: their pipelines are created by periodically shifting the orifices of the rotating two-blade valve 23.

The gas flow discharges under pressure from the tube 27 of the atomizer 1 g 16 oil and directs it to the cadaver 1, the surface. Subsequent gas flows, pass through suzhep1k; sent to the place of lubrication.

In time to close the hole in the lawn of the gadget damper 23, the pressure in the tube 27 of the sprayer 16 decreases slightly, and the oil is below the pump. equal to the height of 1) the position of the inclined holes of the atomizer from the oil level in the bath, fills the internal cavity of the tube 27. When this opening is opened with a shutter, the gas tray again pushes the oil accumulated in the tube 27 and directs it to the surfaces).

At low temperatures, the thickened or freezing oil prevents the gases from passing through 1) through pipe 27, and the gases are directed through the inner pipe 32, where they overcome the resistance of the chassis 33 and go to gearboxes and other transmission units.

Pr: 1 the movement of gases give off heat to the surrounding, 1 him their oil. After warming up sufficiently, the oil is supplied to the places of lubrication: - ;: And in the same way as described above.

The proposed device provides abundant lubrication at the moment of the transmission switching on, which excludes sm.chapap dry t) enu in the pipe / cix pair trans.:, Icssn1-.

Subject invention

1. A device for centralized lubrication of a transmission transmission) and by spraying lubrication with exhaust gases of an internal combustion engine, including an elliptical gas compressor, gas detection unit and ejection lubrication sprayers, so that, in order to avoid cases of dry friction in transmission parts, ejection nozzles mounted in oil baths or crankcases of transmission units, and their spray nozzles are directed onto each rubbing pair.

2. The form of the device

According to claim 1, from .1 and h a 1O 1C and so that. In order to supply exhaust gas to the supercharger, simultaneously pushing it into a stroke, at the end of the exhaust pipe of the engine. a box with hinged dampers installed in it is fitted with an actuator for the gas compressor clutch.

3. Frma implementation of the device in PP. 1 and 2, from the point where, in order to create a pulsating gas flow in the gas pipelines to the ejection sprayers, a gas distribution chamber is installed behind the supercharger, equipped with a drive interrupter, which subsequently blocks the gas pipelines leaving the chamber.
