The oil-mist generating device is characterized in that the upper cover is internally equipped with a compacted gas flow inlet pipe and an oil-mist outlet pipe, the compacted gas flow inlet pipe is connected with an oil-mist nozzle, the oil-mist outlet pipe is connected with the oil-mist nozzle through an oil-mist outlet connector, the oil cup is internally equipped with an oil guiding pipe, the outlet of the oil guiding pipe is connected with the oil-mist nozzle, and a partition board is arranged between the oil cup and the upper cover. The oil cup is internally equipped with a heating temperature control device, and the bottom portion is equipped with a plug screw. The utility model removes an oil feeding and scavenging pump, a lubricating oil cooling fan, a high-capacity lubricating oil tank and a complex monitoring system, is simple in structure, convenient in maintenance and light in weight, improves the cleanliness of a bearing bore, and prolongs the service life. An aircraft engine utilizes oil-mist cooling, thereby simplifying a heat insulation and seal structure of the bearing bore, reducing the manufacturing cost, reducing the weight and the volume of the engine, and increasing the load capacity of an aircraft.
Description
Technical field
The utility model relates to a kind of mist of oil generating means, is specifically related to a kind of mist of oil generating means of high-speed rotating machine.
Technical background
Present rotating machinery is the circulating lubricating and cooling system of aeroengine employing especially, comprise jumbo oil tank, supply dump pump, cooling fan, oily filter, oil mist separator and connecting pipeline, also need whether to have in configuration monitoring lubricating oil pressure, temperature, the oil return watch-dog of impurity and bearing wear simultaneously.So this class lubricating and cooling system equipment is many, supervisory system is complicated, volume is big, Heavy Weight, also consume too much mechanical output, manufacturing expense height simultaneously.Adopt mist of oil that the bearing of aeroengine is lubricated cooling, can reduce the weight and volume of lubricating and cooling system, improve the high-speed rotating machine performance, improve the carrying capacity of aircraft.
Summary of the invention
The purpose of this utility model is for defective that overcomes existing system and deficiency, provides a kind of simple in structure, and volume is little, and is in light weight, lubricated good cooling results, and applicability is strong, the mist of oil generating means that cost is low.
For achieving the above object, mist of oil generating means of the present utility model comprises lubricating cup and loam cake, lubricating cup and loam cake are connected, it is characterized in that being provided with in the described loam cake compressed air stream inlet tube, the mist of oil outer pipe, be connected with oil thrower on the compressed air stream inlet tube, the mist of oil outer pipe connects mouth with mist of oil and is connected by the mist of oil outlet connection; Be provided with oil guide pipe in the described lubricating cup, the outlet of oil guide pipe links to each other with oil thrower; Also be provided with dividing plate between lubricating cup and the loam cake.
Also have additional the temperature controller of heating in the described lubricating cup, the bottom of lubricating cup is provided with plug screw.
Mist of oil generating means of the present utility model is compared with existing apparatus to have: reliable operation, and easy to maintenance; Do not need for dump pump, lubricating oil cooling fan, jumbo oil tank and complicated supervisory system, therefore simple in structure, in light weight; Employing oil mist lubrication cooling, turbidity test and bearing working life of having improved bearing bore; Aeroengine adopts the mist of oil cooling, has simplified heat insulation, the seal structure of bearing bore, has reduced the cost of production of motor, has also reduced the weight and volume of motor simultaneously, thereby has improved the performance of motor, has improved the carrying capacity of aircraft.
