Description
Technical field
The invention belongs to engine art, is related to a kind of rotary engine, and in particular to a kind of top of rotary engine is close
Envelope and lubricating arrangement.
Background technology
Rotary engine（Rotary Engine）It is by German's Fei Jiashi wankels（Felix Wankel, 1902-
1988）Invented, therefore also known as Wankel engine (Wankel Engine).Rotary engine adopts three-apexed rotor rotary motion
It is to complete air-breathing, compression, acting, exhaust stroke, far different with the linear motion of traditional conventional engine.Rotor
The rotor of electromotor is for each revolution with regard to expansion working three times, and general four-stroke engine often revolves the ability work done one that takes two turns
It is secondary, therefore rotary engine has very high power-to-volume ratio.In addition, the unique axially-movable property of rotary engine is not required to it
Crankshaft counterbalance that will be accurate can just reach very high rotating speed.Whole electromotor only has two rotatable parts, eliminates general four punching
More than 20 movable parts such as the inlet and outlet valve of journey electromotor, valve spring, camshaft, engine structure are greatly simplified, and are sent out
The probability of raw failure is also greatly reduced.In addition, rotary engine also has small volume, lightweight, centre of gravity, vibrations
Little the advantages of.
Although rotary engine has the outstanding advantages that conventional reciprocating formula piston engine does not have, oil is there is also
Consumption is high, and exhaust emissions is more, the defect such as under low speed moment of torsion is less than normal.Another obvious problem that rotary engine is present is electromotor
Overhaul life it is too short, general rotary engine operates tens thousand of many kilometers and just needs overhaul once, seldom has more than 100,000 kilometers
, this is mainly due to neighboring chambers space in rotary polygonal piston engine cylinder body only by one piece of end sealing piece isolation, the sealing
Piece rotates with rotor at a high speed and is always linear contact lay along cylinder type face high-speed slide and with cylinder type face, seals pad wear quickly,
Cause three cavitys can not be completely separated, produce gas leak phenomenon, drastically reduce efficiency of combustion, at the same cylinder type face with top
There is cut in the long-term friction of diaphragm seal so that the sealing between end sealing piece and cylinder type face further deteriorates.Japan
Axela Inc. has carried out the lasting research and development of many decades and has improved to the electromotor, material, surface treatment in end sealing piece,
The aspects such as shape, size have done substantial amounts of Optimization Work, and the performance and life-span for making rotary engine has significant progress, so
And, the lubrication problem between end sealing piece and cylinder type face is not solved all the time well, and current lubricating system is to adopt
Lubricating oil is sprayed onto cylinder body cavity and is lubricated by special metering oil pump, and the lubricating oil of penetrating is except small part is at type face and end
Formed on face outside oil film, most of vaporific lubricating oil with one combust of fuel oil or burning to the greatest extent i.e. with exhaust emissions, in addition
Because end sealing piece is moved in one direction, the lubricating oil on type face is easy to be scraped and be difficult to form stable oil by diaphragm seal
Film, test show, once sliding surface has lacked lubricating oil film, the radial-play and resonance of end sealing piece are just easy to be occurred,
So that gas leakage aggravates, sealing deteriorates, in addition, the burning of excessive lubricating oil, thorough, carbon deposit etc. is seriously asked to necessarily lead to burning
Topic, easily makes the exhaust emissions of electromotor exceeded；It can be seen that, the lubrication state of end sealing piece and cylinder type face contact surface, not only directly
The life-span for being related to electromotor is connect, also has very big relation with the efficiency of electromotor, exhaust emissions etc..
For the problem that current rotary engine is present, the present invention enters to the end sealing and lubricating arrangement of rotary engine
Improvement is gone, end sealing piece is changed to into multi-disc by monolithic first, one piece of flexible sealing fin is increased, even if there is diaphragm seal
Radial-play and resonance, also can guarantee that neighboring chambers are air tight；Secondly, increase radial direction lubricant passage way, in end sealing piece and gas
Lubricating oil film is formed persistently on the contact surface in cylinder type face；The device can be greatly decreased the usage amount of lubricating oil simultaneously, so as to significantly
Increase the service life of rotary engine, reduce exhaust emissions, improve the thermal efficiency of electromotor.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of good seal, and lubrication is abundant, can substantially reduce profit
The end sealing and lubricating arrangement of the rotary engine of lubricating oil consumption and increase electromotor running life.
