Circle；Two rolling bearing peripheries are arranged an axle sleeve, and the axle sleeve outer peripheral face is provided with the T-shaped gathering sill in section, in the gathering sill
Piston slider is provided with, piston slider top is connected with the Universal-head of piston rod.
Further, the rotating shaft two ends are arranged with balance weight, and each balance weight side is fixed with the eccentric shaft side
Connection.
Further, the balance weight is circular in 1/3rd, and inner with connecting portion triangular in shape, the connecting portion
It is set in the rotating shaft.
Further, it is arranged with second bearing on the eccentric shaft between the balance weight inner side and one of rolling bearing
Packing ring.
Further, the rolling bearing includes inner ring, outer ring and rolling element positioned there between, the side of inner ring two
Edge stretches out and is provided with the first baffle of annular, and the outer ring both sides of the edge extend internally and are provided with the second baffle of annular, the rolling
Body is located at the first baffle and second baffle is enclosed in the annular space of structure.
Further, the axle sleeve section is in " convex " font, and middle part is the first plane, and the first plane both sides are second flat
Face；Each second plane is provided with the axial trough of annular, and circlip is embedded with the axial trough, the side of the circlip and first plane
Guide collar of the section in inverted L shape is provided between face, the gathering sill is formed between two relative guide collars.
Further, the piston slider is three or four, equiangularly spaced to be distributed in the gathering sill.
The beneficial effects of the invention are as follows：Multiple cylinders of the invention can arrange at grade, bent axle axial dimension
Will not increase as cylinder body quantity increases, the bent axle of multicylinder compressor and the axial dimension of crankcase can be effectively reduced.By
Connected without connecting rod between piston rod and bent axle, crankcase radial dimension will also reduce.

Specific embodiment
Illustrate below in conjunction with the accompanying drawings 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, and it includes bent axle, the bent axle
Including rotating shaft 1 and the eccentric shaft 2 being set in the rotating shaft 1.Two rolling bearings 3, two rolling bearings are arranged outside the eccentric shaft 2
Eccentric shaft 2 between 3 is arranged with clutch shaft bearing packing ring 4.Two peripheries of rolling bearing 3 are arranged an axle sleeve 5, the periphery of axle sleeve 5
Face is provided with the T-shaped gathering sill 50 in section, the gathering sill 50 and is provided with piston slider 6, with piston rod 7 at the top of the piston slider 6
Universal-head connection.The piston slider 6 can be three or four, equiangularly spaced to be distributed in the gathering sill 50, such as Fig. 4,
Shown in Fig. 5.
Specifically, the rolling bearing 3 includes inner ring 31, outer ring 32 and rolling element 33 positioned there between, the inner ring
31 both sides of the edge stretch out and are provided with the first baffle of annular, and the both sides of the edge of outer ring 32 extend internally and are provided with the second gear of annular
Plate, the rolling element 33 is located at the first baffle and second baffle is enclosed in the annular space 34 of structure.
The section of axle sleeve 5 is in " convex " font, and middle part is the first plane 51, and the both sides of the first plane 51 are the second plane 52.
Each second plane 52 is provided with the axial trough of annular, and circlip 53 is embedded with the axial trough, the circlip 53 and first plane
Guide collar 54 of the section in inverted L shape is provided between 51 side, the gathering sill 50 is formed between two relative guide collars 54.
In order that crank rotation stabilization, the two ends of rotating shaft 1 are arranged with balance weight 8, the side of each balance weight 8 and the eccentric shaft
2 sides are fixedly connected.Specifically, the balance weight 8 is circular in 1/3rd, and inner with connecting portion 81 triangular in shape,
The connecting portion 81 is set in the rotating shaft 1.It is arranged on eccentric shaft 2 between the inner side of balance weight 8 and one of rolling bearing 3
There is second bearing packing ring 9.
Piston slider of the invention 6 is stuck in the gathering sill 50 of axle sleeve 5, when rotating shaft 1 of the prime mover with dynamic crankshaft rotates
When, piston slider 6 can arbitrarily swing on the Universal-head of piston rod 7, it is ensured that piston slider 6 in gathering sill 50 all the time with axle
Set 5 is fitted.The direction of rotation of rolling bearing 3 is with bent axle direction of rotation conversely, both turning efforts are offset, it is ensured that piston slider
6 Angle Positions are constant, that is, ensure that cylinder body position.Because eccentric shaft 2 is eccentric rotary, the distance of piston slider 6 to pivot
It is continually changing, 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 know-why used, for those skilled in the art
For, without departing from the spirit and scope of the present invention, it is any based on technical solution of the present invention on the basis of equivalent change
Change, simply replacement etc. obviously changes, belong within the scope of the present invention.
