Description
Technical Field
The utility model relates to a cylinder body, concretely relates to rotary engine cylinder body.
Background
Compared with the common piston engine, the rotor engine has the advantages of small volume, relatively simple structure, good acceleration performance and stable operation. The rotor engine can be used as an aircraft engine to be loaded on a small double-wing aircraft, but the rotor engine also has the following defects: the rotor in the rotor engine rotates in the long cylinder hole similar to a stadium runway due to the fact that the rotor is in the triangular shape, uneven abrasion is easily generated on the inner side wall of the cylinder body, and the service life of the engine is affected.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide a rotor engine cylinder with a reliable structure.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a rotor engine cylinder block, includes the cylinder block body, this internal cylinder hole that is provided with of cylinder block this internal water-cooling passageway that is equipped with of cylinder block, water-cooling passageway with the cylinder hole is adjacent state, the edge of this water-cooling passageway the cylinder hole that the cylinder hole profile is partly surrounded, the one end of water-cooling passageway sets up the water inlet, and the other end is provided with the delivery port cylinder block body lateral wall on still be equipped with and lead to the intake duct and the exhaust passage in cylinder hole, the inner wall of intake duct and exhaust passage is the slope setting respectively, makes its opening size outwards be greater than opening size inwards still be equipped with tungsten carbide spraying layer on the inner wall in cylinder hole.
And a plurality of circular arc-shaped protruding parts are arranged on the inner wall of the water cooling channel.
And the cylinder body is provided with assembling holes which are arranged at intervals along the cylinder hole hub.
The peripheral wall of the outer wall of the cylinder body is provided with regular hexagonal grooves which are arranged vertically and horizontally, and the regular hexagonal grooves which are arranged vertically are communicated with each other.
The utility model discloses a this kind of structure, through laser thermal treatment spraying tungsten carbide coating, the characteristics that are showing on tungsten carbide spraying layer are: hardness is high, wear resistance is good, helps improving fatigue performance, and the setting that intake duct and gas outlet duct inner wall are the slope respectively simultaneously can make gaseous admitting air and give vent to anger more smoothly, and the water-cooling channel that partly surrounds the cylinder hole can effectively improve cooling efficiency, has just so reached reliable technological effect of structure, improves the wearability of cylinder body for life is longer.
The invention is further described with reference to the accompanying drawings and the detailed description.
Drawings
FIG. 1 is a block diagram of an embodiment of the present invention;
fig. 2 is a schematic structural view of an outer wall of a cylinder body according to an embodiment of the present invention.
Detailed Description
The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1, the embodiment discloses a rotor engine cylinder block, including cylinder block body 1, be provided with runway shape cylinder hole 2 in the cylinder block body 1, be equipped with water-cooling channel 3 in cylinder block body 1, water-cooling channel 3 and cylinder hole 2 are adjacent state, this water-cooling channel 3 along cylinder hole 2 that cylinder hole 2 profile partly surrounds, water-cooling channel 3's one end sets up water inlet 31, the other end is provided with delivery port 32, still be equipped with intake duct 4 and exhaust passage 5 that lead to cylinder hole 2 on cylinder block body 1 lateral wall, the inner wall of intake duct 4 and exhaust passage 5 is the slope setting respectively, make its opening size outwards be greater than opening size inwards, still be equipped with tungsten carbide spray coating on cylinder hole 2's inner wall in order to improve the wearability.
The inner wall of the water cooling channel is provided with a plurality of circular arc-shaped convex parts 7. The raised part 7 is close to the position of the cylinder hole 2, so that the area of the inner wall of the water cooling channel can be increased, and the heat dissipation effect is accelerated.
The cylinder body is provided with assembling holes 8 which are arranged at intervals along the hubs of the cylinder holes 2. The assembly holes 8 enable the cover body to be assembled along the contour of the cylinder hole 2, the sealing performance of the cover body is improved, and the structure is more reliable.
Specifically, as shown in fig. 2, hexagonal grooves 9 are formed in the circumferential wall of the outer wall of the cylinder body 1 in a longitudinal direction, and the hexagonal grooves 9 are communicated with each other. Through such structure can effectively improve the radiating effect of cylinder body perisporium, especially with this cylinder body assembly radiating effect better in automobile body head or aircraft head.
By adopting the technical scheme, the tungsten carbide coating is sprayed by laser heat treatment, and the tungsten carbide spraying coating has the remarkable characteristics that: hardness is high, wear resistance is good, helps improving fatigue performance, and the setting that intake duct 4 and gas outlet duct inner wall are the slope respectively simultaneously can make gas admission and give vent to anger more smoothly, and the water-cooling channel that partly surrounds jar hole 2 can effectively improve cooling efficiency, has just so reached reliable technological effect of structure, improves the wearability of cylinder body for life is longer.
