Embodiment
A lot of details have been set forth in the following description so that make much of the utility model.But the utility model can be implemented much to be different from alternate manner described here, and those skilled in the art can do similar popularization under the situation of the utility model intension, so the utility model does not receive the restriction of following disclosed practical implementation.
One of stereogram of the V-type body that Fig. 1 provides for the embodiment of the utility model; Two of the stereogram of the V-type body that Fig. 2 provides for the embodiment of the utility model; Fig. 3 is the stereogram sectional view among Fig. 1.
Please refer to Fig. 1 and Fig. 3, the body in the present embodiment comprises body, and said body 10 is provided with two cylinders of the V-shaped layout of center line, is called first cylinder 1 and second cylinder 2 respectively.Said first cylinder 1 and second cylinder 2 and this body by integral forming are outside equipped with radiating fin at two cylinders.
On said body 10, also be provided with crankcase, crankcase is arranged at the bottom of said first cylinder 1 and second cylinder 2.On the two relative outer walls of said crankcase, also be provided with the two bearings hole, be called the clutch shaft bearing hole 3a and the second bearing hole 3b respectively.The center in said two bearings hole intersects vertically with said first cylinder 1 and second cylinder 2 respectively continuously.The center line of said two cylinders is V-shaped, and all intersects vertically with the line in said two bearings hole.Interfere for avoiding being arranged at producing between the reciprocating part (for example piston) in two cylinders, center line connecting direction separates certain distance to two cylinders in said two bearings hole.
The internal-combustion engine of forming with traditional connecting rod is different with the body of compressor, and the V-type body of the circular slider-crank mechanism of present embodiment still is provided with the guide mechanism of reciprocating part in crankcase.Being described first cylinder 1 and second cylinder 2 can extend in the crankcase respectively along separately cylinder centerlines, and passes crankcase and continue to extend to body 10 inside sidewalls, is connected as a single entity with the sidewall of body 10.Wherein, the extension of said first cylinder 1 is called the first extension part 1a, and the extension of second cylinder 2 is called the second extension part 2a, shown in Fig. 1 and Fig. 3.The described first extension part 1a and the second extension part 2a can be used for the targeting part on the piston seat of ccontaining circular slider-crank mechanism piston, and to this piston reliable guiding are provided.In the IC engine airframe of traditional connecting rod, this then is not set stretches portion.In the present embodiment; The said first extension part 1a and the second extension part 2a are extended to the sidewall 10a of body 10; And make it to be connected as a single entity with sidewall 10a respectively; Bottom with respect to the first extension part 1a and the second extension part 2a is set to unsettled free-ended structure, not only can make the guide mechanism of piston obtain prolonging at vibration-direction, and can improve the rigidity and the intensity of animal economy.
Described first extension part 1a and the structure of the second extension part 2a in crankcase must be made the motion of bent axle and dodging, avoid bent axle when rotating with the interference of said two extension parts.In addition, the internal diameter of the described first extension part 1a and the second extension part 2a must be not identical with second cylinder 2 with said first cylinder 1, and they can have different internal diameter sizes respectively.
In addition, on the said first extension part 1a and the second extension part 2a, some repeated holes 8 that go can also be set, reducing the quality of this V-type body, and save material.And go repeated hole 8 the position and the size setting suitable not influence to being directed to of reciprocating part.
The V-arrangement body of said present embodiment can be used as compressor block, also can be used as IC engine airframe.As different body the time, various structure need be set in the above.For example, when using, camshaft fitting seat 4 need be set between two cylinder in V-arrangements,, the fitting seat of distribution device be set, be used for the tappet etc. through driving valve in the both sides, inside of cylinder in V-arrangement as IC engine airframe.Compressor then need not be provided with this structure.As low pressure compressor the time, it is narrower, thinner that the overhanging portion of two extension parts can be done in the scope of proof strength and rigidity, with the quality of control animal economy.And with higher compressor of delivered pressure and internal-combustion engine the time, can among said first cylinder 1 and second cylinder 2, be pressed into the separated type cylinder sleeve, power transmission reliably and guiding when making piston motion.This separated type cylinder sleeve possesses and the corresponding extending portion of said two extension parts; And each cylinder sleeve extending portion all extends to described extension part bottom always; For guaranteeing enough supports to be provided to the separated type cylinder sleeve; Also be provided with boss 7 in two extension part side walls, as shown in Figure 3, prop up this separated type cylinder sleeve bottom when in its cylinder, packing the separated type cylinder sleeve into.
For improving body rigidity, can also be chosen in the extension part outer wall stiffening rib 6 is set, as shown in Figure 1, stiffening rib 6 is provided with as follows: stiffening rib 6 is provided with by bearing hole 3a week edge extension part bearing of trend, and stiffening rib and body sidewall are crossing and be connected as a single entity.
As required, can also be provided with and the integrated oil sump of this body, meter font or cross stiffening rib are set on the oil sump diapire in the body bottom.Certainly, this oil sump and V-type body body are not necessary for one-body molded, and it can also be separate type.
On the body of described V-type body, other supplementary structure can also be set, integrated machine oil pump seat 5, cylinder cap mounting hole of cylinder head or the like is enumerated here no longer one by one.
Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.
