Abstract
Disclosed is an open gear- lubricating machine, relating to a lubricating machine exclusively used by an open gear. One path of a gas pipe is connected with an external- mix nozzle and the other path is connected with a pneumatic pump. The oil pipe which is connected with the pneumatic pump is connected with the nozzle which is inserted into a constant temperature oil tank. The nozzle is provided with an oil hole and an air hole. A solenoid valve is connected with a main control device and a signal lamp of the main control device. While the utility model is in use, after passing through the solenoid valve, one path of the compressed air is ejected directly from the external- mix nozzle and the other path is ejected with high speed from the external- mixed nozzle after passing through the solenoid valve and a lubricating oil filler. The pneumatic pump absorbs oil from the constant- temperature oil tank and ejects the oil from the external- mixed nozzle after supercharging. At the same time, the compressed air ejected from the external- mixed nozzle has the oil blown and broken into oil- and- gas spray combining oil particles and gas. The oil- and- gas spray is sprayed onto the gear surface to achieve lubrication. The utility model has the advantages that the blockage of the oil system and the nozzle rarely occurs, so the reliability is high; as the LOGO controller is adopted, the automation level is high and the control is convenient and reliable; the service life is long and the maintenance load is small. The utility model can spray open gear oil with high viscosity of 80mm<2>- 2000mm<2>/s and No.1 lubricating grease.

Technical field
The utility model relates to a kind of lubricated machine of exposed gear special use.
Background technique
The transmission of major diameter exposed gear is used very general on large-scale machinery equipments such as steel ball grinder, winch, and domestic this type of quality of equipment is ten hundreds of at present.According to investigations, the exposed gear of exhausted at present big number equipment all is in running under the bad lubricating status, and more or less all there are wearing and tearing in gear, uses the middle gear life-span generally shorter, need often to change, the wasting of resources that causes thus and consumption manpower, financial resources are all very surprising.
The main cause that causes gear wear mainly is that lubrication technology falls behind.Lubricating method commonly used at present: the one, hand oiling, this method does not ensure fully to lubricated; Another kind method is sprayed No. 680 industrial gear oil lubrications exactly, and this method has been got well many than hand oiling, but still has fatal shortcoming, at first is that No. 680 sticking warm natures of oil are bad, and when temperature was raised to 50～60 ℃, oil viscosity only had 320mm
2/ s is easy to be extruded and gets rid of, and its viscosity rises to 3200mm when temperature is lower than 20 ℃
2/ s can cause faults such as spraying difficulty, obstruction, secondly is that the anti-extreme pressure of No. 680 oil is not high, has only 2400N, can not bear the scraping frictional force that exposed gear transmission stress forms.
The exposed gear diameter is big, is difficult for taking closed continuous operation method lubricated, generally all adopts the intermittent type oil jet lubrication so exposed gear lubricates.Through investigation and theory analysis, for guaranteeing that the flank of tooth has enough thick oil film in the intermittent phase, the exposed gear lubricating requirement uses viscosity greater than 1500mm
2The lubricant oil of/s or No. 1, No. 0, No. 00 lubricating grease.The oil-injection machine of No. 680 oil of spray is all very difficult at No. 680 oil of spray below 20 ℃ at present, so can not spray 1500mm at all
2Sticking oil or the fat of/s.Need design for this reason and a kind ofly can spray 1500mm
2The sticking oil of/s or the lubricated machine of fat.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of nozzle and is difficult for obstruction, functional reliability height, easy-maintaining, long service life, can spray 680mm
2/ s～2000mm
2The lubricated machine of the exposed gear of/s high viscosity exposed gear oil and No. 1, No. 0, No. 00 lubricating grease.
The implementation of the utility model purpose is, exposed gear lubricates machine, pneumatic tube divides two-way behind solenoid valve 1, one the tunnel directly connects external mixture type nozzle 9, and another road connects external mixture type nozzle 9 through solenoid valve 2, profit oil strainer 3, Pneumatic oil pump 4, and Pneumatic oil pump 4 is communicated with constant temperature fuel tank 6 by transport pipe, the transport pipe that inserts constant temperature fuel tank 6 connects nozzle through modulating valve 5, solenoid valve 1 connects main control device 11 by lead, and main control device 11 interface I2 meet interlock contact 12, interface Q
1Connect solenoid valve 1, interface Q
2Connect solenoid valve 2, interface Q
3 Connect signaling lamp 16, interface Q
4 Connect signaling lamp 10, external mixture type nozzle 9 has oilhole, pore.
During the utility model work, external pressurized air divides two-way behind solenoid valve 1, and one the tunnel directly connects external mixture type nozzle 9, and another road connects external mixture type nozzle 9 through solenoid valve 2, profit oil strainer 3, Pneumatic oil pump 4, chews ejection at a high speed through annular air.Pneumatic pump 4 oil suction from cryogenic thermostat fuel tank 6, after modulating valve 5 superchargings, arrive external mixture type nozzle 9, go out through nozzle oil perforation, meanwhile chew the 9 pressurized air streams that spray at a high speed oil is blown the oil gas mist that broken formation elaioleucite mixes with gas, spray to the flank of tooth and realize that it is lubricated from external mixture type oil.
The utility model characteristics:
1) because the cryogenic thermostat device is arranged, guaranteed that pneumatic pump can oil suction, after being boosted, oil sends into transport pipe, because the Pneumatic oil pump discharge pressure reaches as high as 30mpa, therefore can spray 680mm again
2/ s～2000mm
2/ s high viscosity exposed gear oil and No. 1, No. 0, No. 00 lubricating grease;
2) owing to oil supply system discharge pressure height, external mixture type nozzle 9 adopts large aperture external circular type nozzles, so oil supply system and the difficult obstruction of nozzle, the functional reliability height;
3) owing to adorned oil sprayer, make the Pneumatic oil pump piston obtain sufficient lubrication at Pneumatic oil pump 4 air inlet pipelines, so the pneumatic pump long service life, maintenance load reduced;
4) since main control device 11 adopt that SIEMENS make LOGO! Controller, and control loop is concisely practical, can work automatically, and the control system height is reliable.
5) regulate oil mass conveniently, the staff need not can directly regulate by any instrument at the scene;
6) owing to be provided with not oil spout protective signal and nozzle obstruction protective signal, contained the fault of the whole petroleum system of oil-injection machine, this trouble signal can in time notify the control room operator on duty to handle, and can prevent effectively that oil-break dry grinding accident from appearring in exposed gear.
