Abstract
The utility model belongs to a rotor engine field reveals serious technical problem to current rotor engine side direction seal structure, the utility model provides an integral side direction sealing device of rotor engine, its characterized in that side seal (1) and angle seal (2) are the whole that the annular links to each other, and its bottom surface has rather than constituting integrative side seal spring (3) and angle seal spring (4).
Description
Technical Field
The utility model belongs to a rotary engine field especially relates to an integral side direction sealing device of rotary engine.
Background
The rotary engine was originally designed by the german engineer's philips wankel and his first engine patent was obtained in 1929. The rotor engine has the advantages of light weight, compact structure, high horsepower and the like, but the rotor engine also has the defects of high oil consumption and short service life. The Side seal structure of the existing Rotor engine is formed by respectively embedding independent Side seal (Side seal), Corner seal (Corner seal), Side seal spring (Side seal spring) and Corner seal spring (Corner seal spring) into a Side seal groove of an engine Rotor (Rotor), and a gap between the Side seal and the Corner seal is a main reason for mixed gas leakage, reduction of the actual compression ratio of the engine and high oil consumption. Therefore, the utility model provides an integral side direction sealing device of rotary engine thoroughly improves current rotary engine side direction sealing and leaks serious disadvantage.
Disclosure of Invention
Reveal serious technical problem to current rotor engine side direction seal structure, the utility model provides an integral side direction sealing device of rotor engine adopts following technical scheme:
an integral lateral sealing device of a rotary engine is characterized in that a side seal (1) and an angle seal (2) are connected into a whole in an annular mode, and a side seal spring (3) and an angle seal spring (4) which are integrated with the side seal (1) and the angle seal are arranged on the bottom surface of the side seal.
The side seal and the corner seal are made of an integral material, the side seal and the corner seal form an annular integral without a gap, and the side seal spring and the corner seal spring which are integrated with the bottom surface of the integral structure formed by the side seal and the corner seal are made of the integral material to form a seamless integral structure. The utility model discloses an integral side direction sealing device of rotary engine's working process does: the integrated lateral sealing device is assembled in a Side sealing groove of an engine Rotor (Rotor), is tightly attached to a plane of an end cover (Side housing) of a Rotor engine under the elastic force action of a Side sealing spring and an angle sealing spring which are integrated on the bottom surface of the integrated lateral sealing device, and moves along with the Rotor, so that mixed gas of a combustion chamber of the Rotor engine is sealed and does not leak to a casing.
Has the advantages that: the integral lateral sealing device of the rotor engine is embedded into a sealing groove on the side surface of the rotor of the engine, and the integral structure is seamless, so that the technical problem that mixed gas leaks to a casing in the compression and combustion processes is thoroughly solved, the actual compression ratio of the engine is improved, oil consumption is reduced, combustion and emission are improved, and meanwhile, the technical problems that tail gas emission is not clean and lubricating oil consumption is high due to the fact that lubricating oil in the casing leaks to a combustion chamber are also reduced due to the fact that the integral structure is seamless. The integral lateral sealing device has the advantages of higher sealing effect, more compact structure, higher strength and more uniform stress, can effectively reduce the depth of the lateral sealing groove of the rotor, and fully improves the high-temperature structural strength of the rotor.
