Description
Technical field
The present invention relates to a kind of transmission mechanism, especially a kind of crank mechanism of natural gas compressor.
Background technique
Reciprocating Natural Gas Compressor traditional at present mainly uses crankshaft to drive connecting rod, and connecting rod band piston is made reciprocal
It moves such a mode and realizes gas compression.However, increase of this compressor with cylinder block quantity, connected on crankshaft
Connecting rod quantity increase, each connecting rod is axially distributed along crankshaft, and therefore, connecting rod quantity is more, crankshaft and crankcase size it is inevitable with
Increase, body volume is also inevitable inevitable to be increased, and manufacture difficulty and manufacturing cost are increased.
Summary of the invention
It is small in size the object of the present invention is to provide a kind of crank mechanism of natural gas compressor, it is compact-sized, it is not easy out
Existing mechanical breakdown, reduces manufacture difficulty and manufacturing cost.
To achieve the above object, the present invention takes following technical scheme:
A kind of crank mechanism of natural gas compressor, it includes crankshaft, which includes shaft and be set in the shaft
Eccentric shaft；The bias outer shaft sleeve sets two rolling bearings, and the excentric sleeve between two rolling bearings is equipped with first axle support pad
Circle；Two rolling bearing peripheries are arranged an axle sleeve, the axle sleeve outer peripheral surface guide groove T-shaped equipped with section, in the guide groove
Equipped with piston slider, it is connect at the top of the piston slider with the Universal-head of piston rod.
Further, the both ends of the shaft is arranged with balance weight, and each balance weight side is fixed with the eccentric shaft side
Connection.
Further, the balance weight is round in one third, and inner end has interconnecting piece triangular in shape, the interconnecting piece
It is set in the shaft.
Further, second bearing is arranged on the eccentric shaft on the inside of the balance weight between one of rolling bearing
Washer.
Further, the rolling bearing includes inner ring, outer ring and rolling element positioned there between, the inner ring two sides
Edge extends outwardly equipped with annular first baffle, which extends internally equipped with annular second baffle, the rolling
Body is located at the first baffle and second baffle encloses in the annular space of structure.
Further, the axle sleeve section is in " convex " font, and middle part is the first plane, which is second flat
Face；Each second plane is equipped with the axial trough of annular, is embedded with circlip in the axial trough, the side of the circlip and first plane
It is equipped with the guide collar that section is in inverted L shape between face, forms the guide groove between two opposite guide collars.
Further, the piston slider is three or four, equiangularly spaced to be distributed in the guide groove.
The beneficial effects of the present invention are: multiple cylinders of the invention can be arranged in the same plane, crankshaft axial dimension
It will not increase as cylinder body quantity increases, the crankshaft of multicylinder compressor and the axial dimension of crankcase can be effectively reduced.By
It is connected between piston rod and crankshaft without connecting rod, crankcase radial dimension will also be reduced.

Specific embodiment
It illustrates with reference to the accompanying drawing and the present invention is described in more detail.
As Figure 1-Figure 5, the present invention provides a kind of crank mechanism of natural gas compressor, it includes crankshaft, the crankshaft
Including shaft 1 and the eccentric shaft 2 being set in the shaft 1.Two rolling bearings 3, two rolling bearings are arranged outside the eccentric shaft 2
Eccentric shaft 2 between 3 is arranged with first bearing washer 4.Two 3 peripheries of rolling bearing are arranged an axle sleeve 5,5 periphery of axle sleeve
Face is equipped with the T-shaped guide groove 50 in section, is equipped with piston slider 6 in the guide groove 50,6 top of piston slider and piston rod 7
Universal-head connection.The piston slider 6 can be three or four, it is equiangularly spaced to be distributed in the guide groove 50, as Fig. 4,
Shown in Fig. 5.
Specifically, which includes inner ring 31, outer ring 32 and rolling element 33 positioned there between, the inner ring
31 both sides of the edge extend outwardly equipped with annular first baffle, which extends internally equipped with annular second gear
Plate, which is located at the first baffle and second baffle encloses in the annular space 34 of structure.
5 section of axle sleeve is in " convex " font, and middle part is the first plane 51, which is the second plane 52.
Each second plane 52 is equipped with the axial trough of annular, is embedded with circlip 53 in the axial trough, the circlip 53 and first plane
It is equipped with the guide collar 54 that section is in inverted L shape between 51 side, forms the guide groove 50 between two opposite guide collars 54.
In order to stablize crank rotation, which is arranged with balance weight 8, each 8 side of balance weight and the eccentric shaft
2 sides are fixedly connected.Specifically, the balance weight 8 is round in one third, and inner end has interconnecting piece 81 triangular in shape,
The interconnecting piece 81 is set in the shaft 1.It is arranged on eccentric shaft 2 between 8 inside of balance weight and one of rolling bearing 3
There is second bearing washer 9.
Piston slider 6 of the invention is stuck in the guide groove 50 of axle sleeve 5, when shaft 1 of the prime mover with dynamic crankshaft rotates
When, piston slider 6 can arbitrarily be swung on the Universal-head of piston rod 7, guarantee piston slider 6 in guide groove 50 always with axis
5 fitting of set.The direction of rotation and crankshaft direction of rotation of rolling bearing 3 are on the contrary, the two turning effort counteracting, ensure that piston slider
6 Angle Positions are constant, that is, ensure that cylinder body position.Since eccentric shaft 2 is to be eccentrically rotated, piston slider 6 arrives the distance of rotation center
Constantly variation drives the piston of piston rod 7 to move back and forth in the cylinder, is finally reached the purpose of compressed gas.
The above is presently preferred embodiments of the present invention and its technical principle used, for those skilled in the art
For, without departing from the spirit and scope of the present invention, any equivalent change based on the basis of technical solution of the present invention
Change, simple replacement etc. is obvious changes, all fall within the protection scope of the present invention.
