This circular slider set comprises two smooth blocks that structure is identical, is respectively first smooth block 1, second smooth block 2.Said first smooth block 1 connects as one through locating stud 3 with said second smooth block 2.
Below be example with said first smooth block 1, the structure of the smooth block of forming this circular slider set is described.
Fig. 4 is the front view of the 1-A end face side of first smooth block 1.As shown in the figure; On the first end face 1-A of said first smooth block 1; Its eccentric opening 1-1 both sides are respectively arranged with the first smooth block positioning pin hole 1-2; This first smooth block positioning pin hole 1-2 can also can be through hole for blind hole, and two first smooth block positioning pin hole 1-2 are arranged in the both sides of the said first smooth block eccentric opening 1-1 axisymmetricly with the line at said first smooth block eccentric opening 1-1 center and smooth block center.Smooth block end face shown in Fig. 4 is when forming circular slider set,, can find out from this figure that the end face of this smooth block is not provided with the end face oil groove with another smooth block opposing end faces 1-A.
As shown in Figure 5, in two end faces of this smooth block, the first end face 1-A is a plane that does not have boss, certainly, eccentric opening is still arranged on this end face and go recessed part such as heavy groove; This first end face 1-A is when forming circular slider set and another smooth block opposing end faces.The second end face 1-B is a step surface, the lobed step of part of its first smooth block eccentric opening 1-1.
Said second smooth block 2 has identical structure with said first smooth block 1.Promptly the second smooth block eccentric opening 2-1 that is provided with of this second smooth block 2 is provided with the second smooth block positioning pin hole 2-2 in this second smooth block eccentric opening 2-1 both sides.The first end face 2-A of this second smooth block 2 is a plane that does not have boss, the step surface that the second end face 2-B has raised step for the part at the second smooth block eccentric opening 2-1.
Please referring to Fig. 6, this figure is the parts drawing of locating stud 3.These locating stud 3 middle parts have boss 3-1, and these boss both sides are respectively left pin section 3-2 and right pin section 3-3, and the two ends of locating stud 3 is provided with angle of deflection.
Above-mentioned locating stud 3 can adopt variety of way to process.For example, these locating stud 3 various pieces are made into integration, and said boss is the bigger part of locating stud shank mid diameter.Specifically can adopt turning processing, the different diameter of different size Position Design is provided with one section bigger shaft part of diameter at the middle part and gets final product as said boss 3-1 in the axial direction.Above-mentioned locating stud 3 also can adopt two systems to become; At first make the shank of said locating stud 3; This shank is one and axially goes up the cylinder shank that each cross section has same diameter; Only angle of deflection is set, then the friction tight annulus of an internal diameter and this straight pin body diameter is overlapped the middle part that is enclosed within this cylinder shank with hot pressing mode, just obtain a complete locating stud at two ends; Said annulus position is said boss.
Above-mentioned first smooth block 1 is combined to form the double-round slide group with second smooth block 2 through being connected of locating stud 3, and is specifically as shown in Figure 3.
Said first smooth block 1, second smooth block 2 are relative with 180 ° of phase places each other; So-called relative with 180 ° of phase places; Specifically be that said first smooth block 1 is relative with eccentric opening with said second smooth block 2; Promptly the first smooth block eccentric opening 1-1 is relative with the second smooth block eccentric opening 2-1, and the axis of two eccentric openings is on same straight line; Simultaneously, the center line of two smooth blocks then is distributed in the both sides of this eccentric opening axis, and is axisymmetric with the axis of two eccentric openings.The opposing end surface of two smooth blocks is first smooth block, first end face 1-A and second smooth block, the first end face 2-A.The positioning pin hole of first end face of above-mentioned two smooth blocks simultaneously also respectively relatively.The left pin section 3-2 of said locating stud 3 inserts the positioning pin hole 1-2 of first smooth block 1 that is arranged in the left side; The right pin section 3-3 of said locating stud 3 inserts the positioning pin hole 2-2 of second smooth block 2 that is arranged in the right side; Said boss 3-1 separates the opposing end surface of first smooth block 1 and second smooth block 2; Make to have a segment distance L between the two, this distance L is enough to for the piston that smooth block is placed in wherein enough gaps are provided, and its to-and-fro motion track can not interfered each other.Therefore, first end face of said first piston 1 and said second piston 2 can adopt the plane and not be used in here and thicken.
After forming above-mentioned circular slider set, can find out that the opposing end surface of said first smooth block 1 and second smooth block 2 can not fitted each other, so also just not have wearing and tearing each other.Simultaneously, after crank pin inserts said first smooth block eccentric opening 1-1 and the said second smooth block eccentric opening 2-1, in its movement process outside crank pin the aperture surface of diametric plane and eccentric opening cooperatively interact, need cool off through cold oil at this fitting surface.Because the opposing end surface of said first smooth block 1 and said second smooth block 2 is not fitted each other, and the cold oil of this rubbing surface can be flowed out smoothly.
Please referring to Fig. 7, this figure is the side view of second embodiment of the invention.This illustrates one three circular slider set.Structure and the foregoing description of each smooth block of this three circular slider set are basic identical, repeat no more at this.
As can beappreciated from fig. 7; The middle middle circle slide block 4 that is arranged in of this three circular slider set is the dynamic balancing smooth block that is installed in the circular slider accommodation hole of dynamic balance slide block; Its thickness is thicker than the work smooth block of its right and left, and this is because the quality of this middle circle slide block 4 need equal the quality sum of both sides smooth block.About 4 two end faces of this middle circle slide block are the plane.Two groups of adjacent smooth blocks all separate through the boss in the middle of the locating stud to each other, and are identical with the double-round slide group that adopts first embodiment.In this embodiment, the smooth block in said middle circle slide block and its left side adopts one group of locating stud location, adopts other one group of locating stud location with the smooth block on its right side.This is because the locating stud middle part is provided with boss, it can not directly be adopted pass having strong market potential of positioning pin hole.
The circular slider set that above-mentioned two embodiments provide has all adopted corresponding smooth block; The common trait of these smooth blocks is; Itself and another adjacent end face of smooth block adopts the plane that boss is not set in the eccentric opening position to get final product, and need boss be set in the eccentric opening position.The end face oil groove is not set on the adjacent face of this smooth block, and its positioning pin hole adopts blind hole or through hole all can.Positioning pin hole has two, and with the both sides that axisymmetric is arranged in said eccentric opening that are wired at eccentric opening center and smooth block center.
Although in the foregoing description; The design that said locating stud all adopts the pin section of boss both sides to have same diameter; But the pin section that also is not precluded within the locating stud both sides has the situation of different diameters, and at this moment, the positioning pin hole on the opposing end surface of adjacent smooth block also has different diameters.
Adopt after the above-mentioned circular slider set, owing to the opposing end surface of adjacent smooth block is not fitted each other, but boss separates in the middle part of the pin that is positioned, and makes circular slider set compared with prior art, has many-sided improvement.Be in particular in following four aspects.
At first; Said locating stud middle part boss separates adjacent smooth block; Make between the piston at adjacent smooth block place or the space length between piston and the dynamic balance slide block is enough to avoid movement interference, obtain this space length so the mode of boss no longer need be set through the smooth block eccentric opening position at opposing end surface.So just increased the flexibility of smooth block design.
Secondly; The opposing end surface of said adjacent smooth block is not fitted; The outer diametric plane of crank pin of the eccentric opening of flowing through and the cold oil of the movement pair surface that the eccentric opening aperture surface forms can be flowed out smoothly; The end face oil groove that supplies cold oil to flow out no longer need be set on above-mentioned opposing end surface, thereby reduce the operation of smooth block processing.
Its three, the opposing end surface of said adjacent smooth block is no longer fitted, and makes these two end faces that fricative each other wearing and tearing can not take place, and has prolonged the working life of smooth block.
Its four because locating stud middle part is provided with boss, make it can slippage from positioning pin hole, make the outer end of positioning pin hole that the plug that prevents its slippage need not be set.
The circular slider set that the foregoing description provides is used on the internal-combustion engine or compressor that adopt circular slider-crank mechanism, just obtained the embodiment of internal-combustion engine or compressor.
Though the present invention with preferred embodiment openly as above; But it is not to be used for limiting the present invention; Any those skilled in the art are not breaking away from the spirit and scope of the present invention; Can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
