Description
Technical field
The utility model belongs to the Compressor Technology field, relates to a kind of reciprocating-piston compressor, particularly a kind of sliding rod type twin-tub reciprocating-piston compressor.
Background technique
As everyone knows, Reciprocting piston compressor mainly relies on connecting rod to realize conversion between the to-and-fro motion of rotatablely moving of crank and piston, brought a tangible drawback thus, Here it is, and power that connecting rod affacts on the piston is the power of a swing, and this power can cause piston that cylinder action is had very big side pressure and causes bigger friction and wear.
Summary of the invention
The utility model provides a kind of sliding rod type twin-tub reciprocating-piston compressor, and purpose is effectively to reduce the friction and wear between the main movement parts of compressor.
The purpose of this utility model is achieved in that
A kind of sliding rod type twin-tub reciprocating-piston compressor, it comprises: the piston and the cylinder of a crank, a framework, two connecting rods, two opposed distributions, described piston is placed in the cylinder and is slidingly matched with it, one end of described two connecting rods is connected with described two pistons respectively, the other end of two connecting rods is connected with described framework, it is characterized in that being provided with a slide bar, described slide bar is arranged in the framework, axle sleeve structure is made at the middle part of slide bar and rotating sleeve is contained on the crank, and the two ends of slide bar cooperate with framework by rolling element.
Above-mentioned framework is integral frame or split type framework.
Above-mentioned cylinder adopt straight line to interposed structure or dislocation to interposed structure.
Above-mentioned rolling element is roller, roll sleeve, needle roller or ball.
Above-mentioned roller, needle roller or ball are subjected to frame constraint and move with framework.
Above-mentioned roller, needle roller or ball are subjected to the slide bar constraint and move with slide bar.
Above-mentioned slide bar is contained on the crank by the bearing rotating sleeve.
The above-mentioned connecting rod and the cooperation place of cylinder are set with seal ring.
A kind of sliding rod type twin-tub of the utility model reciprocating-piston compressor adopts the opposed layout structure of double-piston, and cooperate and to drive framework and then drive link and piston with slide bar and move reciprocatingly: because of the piston lateral pressure that crank skew cylinder-bore axis produces is born jointly by two pistons, because the span of two pistons is bigger, so the active force of piston and cylinder is less, that is the friction and wear between them is less; Because of being furnished with rolling element between slide bar and the framework, so the friction and wear between them is less; Because of slide bar is contained on the crank by the bearing rotating sleeve, so the friction and wear between them is less.In sum, the utility model can effectively reduce the friction and wear between the main movement parts of compressor.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 2 a structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
A kind of sliding rod type twin-tub reciprocating-piston compressor, comprise: a crank 1, a framework 2, two connecting rods 3, the piston 4 of two opposed distributions and cylinder 5, described piston 4 is placed in the cylinder 5 and is slidingly matched with it, one end of described two connecting rods 3 is connected with described two pistons 4 respectively, the other end of two connecting rods 3 is connected with described framework 2, wherein: connecting rod 3 and piston 4 can also can be for integrally manufactured for being fastenedly connected, connecting rod 3 and framework 2 can also can be for integrally manufactured for being fastenedly connected, and framework 2 can be made overall structure and also can make the branch body structure and be fastenedly connected and be one; Be provided with a slide bar 6 in addition, described slide bar 6 is arranged in the framework 2, axle sleeve structure is made at the middle part of slide bar 6 and rotating sleeve is contained on the crank 1, and perhaps the middle part of slide bar 6 is contained on the crank 1 by bearing housing, can reduce the friction and wear of slide bar 6 and crank 1 like this; In this case, the two ends of slide bar 6 cooperate with framework 2 by rolling element 7, wherein rolling element 7 is subjected to the constraint of framework 2 and moves with framework 2, the situation of this moment is the surface that rolling element 7 is close to slide bar 6 roll (allowing to occur certain sliding phenomenon), it is to be noted that described rolling element 7 can be a roller, roll sleeve, needle roller or ball, slide bar 6 then can be various shaft-like or platy structures, rolling element 7 can be that a contact matching also can be the line contact matching with the contact matching of slide bar 6, for this reason can with slide bar 6 and rolling element 7 to cooperate part to make plane, arc groove shape or other channel form; Need to prove in addition, the piston 4 of two opposed distributions and cylinder 5 can adopt straight line to interposed structure, this moment, the axis of two cylinders 5 was coaxial state (allowing to exist certain foozle and alignment error), certainly piston 4 and cylinder 5 can also adopt the opposed structure of dislocation, and the axis of two cylinders 5 is parallel to each other but does not overlap at this moment; When compressor adopts when oil lubrication is arranged, scurry in the inlet casing 5 in order to prevent lubricant oil, can be at the cooperation place suit seal ring 8 of connecting rod 3 with cylinder 5, and when compressor employing oil-free lubrication, then can not need this Sealing; In order to make compressor operating more steady, centrifugal type equilibrium block 9 can be set on crank; Present embodiment adopts double-piston 4 opposed layout structures, and cooperate and to drive frameworks 2 and then drive link 3 and piston 4 with slide bar 6 and move reciprocatingly, obviously, the piston lateral pressure that the axis that is offset cylinder 5 because of crank 1 produces is born jointly by two pistons 4, because the span of two pistons 4 is bigger, so the active force between piston 4 and the cylinder 5 is less, that is the friction and wear between them is less; Because of becoming to roll and cooperate being furnished with rolling element 7 between slide bar 6 and the framework 3, so the friction and wear between them is less; Because of slide bar 6 is contained on the crank 1 by the bearing rotating sleeve, so the friction and wear between them is also less; In sum, the utility model can effectively reduce the friction and wear between the main movement parts of compressor.
The label of part, title and function are inherited Fig. 1 and embodiment 1 among the figure, the structure of present embodiment is substantially the same manner as Example 1, institute's difference is: rolling element 7 is subjected to the constraint of slide bar 6 and moves with slide bar 6, the situation of this moment is the matching surface that rolling element 7 is close to framework 2 roll (allowing to occur certain sliding phenomenon), the same purpose of reducing friction and wearing and tearing of realizing can be made plane, arc groove shape or other channel form with the part that cooperates of framework 2 and rolling element 7 at this moment.
The foregoing description only is some preferred embodiments of the present utility model; be not to limit protection domain of the present utility model according to this; so: all various equivalences of doing according to structure of the present utility model, shape and principle change, and all should be covered by within the protection domain of the present utility model.
