Abstract
A slant sealed piston with merged ring features that the piston ring formed by merging upper and lower rings is installed at least one ring slot of piston.The matching surface of two rings has proper slope relative to axis and two rings have same slope. The another top surface of piston ring is a plane perpendicular to axis. The total thickness of merged ring is correspondent to the width of ring slot. Its advantages include no relative rotation between upper and lower rings, high cross-section strength, high mechanical efficiency and long service life of piston ring.
Description
The present invention relates to the piston and the piston ring of machines such as motor, gas compressor, concrete is a kind of inclined-plane sealed type and encircles piston.
Piston and piston ring that tradition is used all are that single groove is joined monocycle, the opening of using during flexible distending on the piston ring, there is shortcoming in it is when causing the opening distending excessive when piston ring scuffing, can cause engine power to reduce, also influence simultaneously the working life of piston ring, in order to address this problem, the somebody has proposed to use the piston ring structure of single groove dicyclo, this dicyclo is on two, the piston ring that lower plane is parallel to each other, on during installation, under encircle opening and stagger, its shortcoming notes aperture position when being installation, the assembling trouble, and in using, following ring may rotate opening is aligned mutually, thereby has lost the meaning that dicyclo is set.Prevent that the device that rotates from avoiding upper and lower ring opening to align if set up, its structure is too complicated again, increases manufacture cost, and prior art has further improvement and perfect necessity.
The purpose of this invention is to provide a kind of inclined-plane sealed type of having improved and encircle piston, upper and lower ring relatively rotated during it can prevent to use automatically, keep the opening of upper and lower ring to stagger, and the not uniform thickness shape of ring has strengthened the cross-sectional strength of ring when distending, frangibility not during installing ring, reach and improve mechanical output power, improve gas compressor air displacement and volumetric efficiency.Prolong the piston ring purpose in working life.
The object of the present invention is achieved like this;
A kind of inclined-plane sealed type is also encircled piston, and the opening that flexible distending is used on the piston ring is characterized in that:
A. at least one annular groove of piston, be equipped with two up and down and the piston ring that connects;
The fitting surface of b. described piston and ring is the inclined-plane that relative shaft axis has suitable gradient and two ring oblique angles to equate, another end face of piston ring is the plane vertical with shaft axis, should and encircling with the superimposed back of inclined-plane contact is upper and lower parallel plane assemblying body, and the annular groove width of its total thickness and piston is corresponding.
The gradient of described piston and engagement of loops face is pressed as the upper/lower positions setting: and the opening of ring lays respectively at the thickness thinnest part of each ring.
The thinnest part and the thickness correspondent equal of two ring thicknesses in the described and ring piston.
The present invention has following actively useful effect:
1. can guarantee that ring and the opening that encircles down stagger, and prevent to rotate;
2. upper and lower ring is bevelled not uniform thickness ring, at the frangibility place of ring thicker thickness is arranged, thereby has improved the resistance to flexure of ring when opening, and reduces the damage percentage when installing;
3. under same oil consumption, can improve output power and mechanical efficiency;
4. can fuel-economizing under same output power, comprise fuel saving oil, lubricant oil;
5. improve gas compressor air displacement and volumetric efficiency;
6. prolong the working life of piston and piston ring;
7. reduce of the pollution of motor institute exhaust gas discharged to environment.
Now in conjunction with the accompanying drawings with preferred embodiment;
Fig. 1 is a user mode schematic representation of the present invention;
Fig. 2 is the present invention's structure of piston schematic representation in parallel;
Fig. 3 is the 2A-A parting view of figure.
Inclined-plane of the present invention sealed type is also encircled piston, comprises piston 1 and piston ring 2, the opening 3 that flexible distending is used on the piston ring 2;
A. at least one annular groove of piston, be equipped with two up and down and the piston ring 2A and the 2B that connect, can in an annular groove, adorn and encircle during enforcement, also can in all annular grooves, adorn and encircle, comprise compression ring and oil ring.
B, described piston also encircles the inclined-plane that the fitting surface 201 of 2A, 2B has suitable gradient and two ring oblique angles to equate for relative shaft axis, another end face 202,203 of piston ring is the plane vertical with shaft axis, should and ring be the parallel assemblying body in upper and lower plane 202,203 with the superimposed back of inclined-plane contact, the annular groove width of its total thickness and piston is corresponding.
During enforcement, the gradient of described piston and engagement of loops face 201 is pressed as the upper/lower positions setting: and the opening 3 of ring lays respectively at the thickness thinnest part of each ring.
In preferred embodiment, the thinnest part and the thickness correspondent equal of two ring thicknesses in the described and ring piston, if the thickness thickness of last ring 2A is a1, thinnest part is b1, and the following thickness thickness of encircling 2B is a2, and thinnest part is b2,
A1=a2 should be arranged
b1=b2
Better manufacturability is arranged like this, be convenient to processing.
