Description
Technical Field
The utility model relates to a machine casket structural design technical field especially relates to a be used for aviation piston engine right side machine casket.
Background
The casing is one of the important parts of the aircraft engine, is a base of the whole engine, is a main bearing part on the aircraft engine, has a complex shape structure, has different shapes of the casings at different positions of different engines and engines, and determines the shape of the casing according to the functions of the casing parts.
At present, compression ignition type aviation kerosene piston engines mainly used by aviation piston engines are basically four-stroke engines, have low power-weight ratio and adopt more air cooling so as to reduce the complex design of internal cavities of the engines. The traditional two-stroke engine adopts crankcase air intake, lubricating oil is mixed into fuel oil to moisten and exchange the engine, the structures of scavenging, lubricating, cooling and the like are complex, and the power-weight ratio is low.
Consequently, all be unsuitable as aviation piston engine to present four-stroke kerosene engine and two-stroke kerosene engine machine and use, the utility model relates to an aviation piston engine is the gasoline piston engine of a four-stroke, provides an aviation piston engine right side machine casket to the gasoline piston engine of four-stroke.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a be used for aviation piston engine right side machine casket through inside curved surface transition design, provides the base for all parts of engine, simultaneously through the crankshaft groove, the downthehole oilhole of camshaft groove and hydraulic tappet provides lubrication and cooling for the part of all motion departments in the engine.
To achieve the purpose, the utility model adopts the following technical proposal: the utility model provides a be used for aviation piston engine right side machine casket, includes the mounting base body that a plurality of curved surfaces formed, be formed with the holding chamber on the mounting base body, be provided with the strengthening rib on the lateral wall in holding chamber, the holding intracavity is provided with the brace rod, both sides are provided with camshaft groove and bent axle groove respectively about the brace rod, the holding intracavity of camshaft groove side is provided with hydraulic tappet hole, the holding intracavity of bent axle groove side is provided with the cylinder hole.
In one embodiment, the crankshaft groove, the camshaft groove and the hydraulic tappet hole are all provided with oil holes.
In one embodiment, the crankshaft groove, the camshaft groove and the oil hole in the hydraulic tappet hole are connected with oil passages.
The utility model discloses following beneficial effect has at least: above-mentioned aviation piston engine right side machine casket through inside curved surface transition design, provides suitable position space for bent axle groove, camshaft groove and hydraulic tappet hole, provides the base for all parts of engine, has simplified the project organization, has alleviateed the machine casket weight.

Fig. 1 is a schematic structural diagram of a right casing according to an embodiment of the present invention;
in the figure: the hydraulic support comprises a mounting base-1, an accommodating cavity-2, a reinforcing rib-3, a supporting rib-4, a camshaft groove-5, a crankshaft groove-6, a hydraulic tappet hole-7, a cylinder hole-8, an oil hole-9 and an oil way-10.
Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
As shown in fig. 1, a right casing for an aviation piston engine comprises a mounting base body 1 formed by a plurality of curved surfaces, wherein a containing cavity 2 is formed on the mounting base body, reinforcing ribs 3 are arranged on the side wall of the containing cavity, supporting ribs 4 are arranged in the containing cavity, a camshaft groove 5 and a crankshaft groove 6 are respectively arranged on the upper side and the lower side of each supporting rib, a hydraulic tappet hole 7 is arranged in the containing cavity on the side of the camshaft groove, and a cylinder hole 8 is arranged in the containing cavity on the side of the crankshaft groove. Oil holes 9 are formed in the crankshaft groove, the camshaft groove and the hydraulic tappet holes, and the oil holes are connected with oil passages 10.
The crankshaft groove can control the crankshaft to stably rotate in the groove, and a proper space is reserved for enabling the crankshaft not to interfere with other structures when the crankshaft rotates. The camshaft groove can control the camshaft to stably rotate in the groove, an oil outlet is designed in the camshaft groove, and hydraulic pressure enters the connecting position of the camshaft and the casing from the oil outlet to lubricate and cool the camshaft and the base. The cylinder hole is arranged at the lower side of the axis of the crank groove, and a space is reserved so that a connecting rod in the cylinder hole cannot interfere with other structures when moving.
The hydraulic tappet hole enables the hydraulic tappet to only do reciprocating motion at the position, and an oil outlet hole is formed in the hydraulic tappet hole and is used for lubricating and cooling the hydraulic tappet.
The curved surfaces are used among the crankcase crankshaft groove, the camshaft groove and the hydraulic tappet hole to connect the structures together to form a base of the engine, so that the design structure is simplified, and the weight of the crankcase is reduced.
This right cartridge receiver provides fixed mounted position for all accessories such as bent axle, camshaft, cylinder, hydraulic tappet, through inside curved surface transition design, for the crankshaft groove, camshaft groove and hydraulic tappet hole provide suitable position space, for all parts of engine provide the base, has simplified the design structure, has alleviateed cartridge receiver weight. The crankshaft groove, the camshaft groove and the oil hole and the oil path inside the hydraulic tappet hole are connected, so that lubrication and cooling are provided for all moving parts in the engine.
