Embodiment
In order to make those skilled in the art understand the technological scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.Should be pointed out that description and description order to concrete structure in this part only are the explanations to specific embodiment, should not be regarded as that the protection domain of the utility model is had any restriction.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the structural representation of a kind of universal connector that Fig. 1 is provided for the utility model embodiment, Fig. 2 are the partial sectional view at first visual angle (Y direction) of Fig. 1, and Fig. 3 is the partial sectional view at second visual angle (Z-direction) of Fig. 1.
As shown in the figure, the universal connector of present embodiment mainly comprises four ear hinged seats 1 (first hinged seat), multidiameter shaft 2 (first), first axle sleeve 3, second axle sleeve 4, ears hinged seat 5 (second hinged seat), bearing pin 6, lubricating cup 7, gudgeon 8 (second) and meniscus 9.Its structure annexation is following:
The a pair of journal stirrup of four ear hinged seats 1 is provided with and the corresponding axis hole of the size of multidiameter shaft 2; Multidiameter shaft 2 (as shown in Figure 2) wide at the top and narrow at the bottom; Be installed on the axis hole of this a pair of journal stirrup; One fixed plate (as shown in Figure 1) can be set above multidiameter shaft 2, and the two ends of fixed plate through the journal stirrup locking of two bolts and four ear hinged seats 1, move up and down to avoid the relative four ear hinged seats 1 of multidiameter shaft respectively;
One end and the multidiameter shaft 2 between a pair of journal stirrup of gudgeon 8 are hinged; It is (as shown in Figure 2 that hinged mode can be that multidiameter shaft 2 passes the gudgeon 8 that has axis hole; This axis hole is corresponding with the size of multidiameter shaft); Also can be that gudgeon 8 passes the multidiameter shaft 2 (this axis hole is corresponding with the size of gudgeon) that has axis hole, thereby gudgeon 8 can rotate around multidiameter shaft 2 relative four ear hinged seats 1, multidiameter shaft 2 also be provided with first axle sleeve 3 with gudgeon 8 hinged places;
The other end of gudgeon 8 is connected with ears hinged seat 5, and ears hinged seat 5 is provided with the corresponding axis hole of size with gudgeon 8 the other ends, and the other end of gudgeon 8 stretches into this axis hole; The axle journal of the other end of gudgeon 8 is provided with annular groove; Ears hinged seat 5 is provided with meniscus 9 in the position corresponding with this axle journal; Meniscus 9 is provided with and the corresponding projection of this annular groove shape, and this projection is inserted in the annular groove, along with projection slides along annular groove; Ears hinged seat 5 rotates around gudgeon 8, also is provided with second axle sleeve 4 between the axis hole of gudgeon 8 and ears hinged seat 5;
Four ear hinged seats 1 can be hinged with left and right sides two-part fuselage of coal winning machine through bearing pin 6 respectively with ears hinged seat 5.
In the course of the work, when the left and right sides of coal winning machine two-part when X-axis direction relatively rotates, the gudgeon of universal connector 8 forms revolute pairs with ears hinged seat 5 and then eliminates the destruction of tilting force to coal winning machine, guarantees the trouble-free operation of coal winning machine; When the left and right sides of coal winning machine two-part when Y direction has rotation trend; Four ear hinged seats 1 (or ears hinged seat 5) are connected on the coal winning machine through bearing pin 6 and form revolute pair and overcome because of coal winning machine two-part do not produce the destruction of internal stress to coal winning machine at same horizontal plane, guarantee that the coal machine normally moves; When the left and right sides of coal winning machine two-part when Z-direction relatively rotates, four ear hinged seats 1 are connected to form revolute pair with gudgeon 8 through multidiameter shaft 2 can have certain amounts of rotation around the Z axle to guarantee coal winning machine left and right sides two-part, guarantees coal machine life-span and stable operation.
In the course of the work, when a coal winning machine part took place can't drive unusually, another part passed to four ear hinged seats 1 or ears hinged seat 5 through bearing pin 8 with power, impelled gudgeon 8 to obtain pressure or tensile stresss.When gudgeon 8 obtained pressure, gudgeon 8 closely contacted with the surface of contact of ears hinged seat 5, transmitted thrust, promoted the walking of another part coal winning machine, i.e. " one pushes away one "; When gudgeon 8 obtained tensile stress, the annular groove side of gudgeon 8 contacts with the projection of meniscus 9 transmitted pulling force, drags the running of another part coal winning machine, i.e. " one-to-one ".
In the course of the work; When receiving great tensile stress between the two-part of the coal winning machine left and right sides, because the axle journal of gudgeon 8 is provided with annular groove, the axle journal of gudgeon 8 at first fractures; Avoid Coal Winning Machine stressed excessive and go to pot, thereby complete machine is played overload protective function.
Need to prove, owing to produce frictional force in the revolute pair movement process, for prolonging the working life of universal connector; Rotate vice division chief at gudgeon 8 with multidiameter shaft 2 and add first axle sleeve 3, gudgeon 8 adds second axle sleeve, 4, two place's axle sleeves with ears hinged seat 5 rotation vice division chiefs can take unified lubricating system; Promptly get through " diesis " oil circuit (as shown in Figure 3) in gudgeon inside; Form the oil circuit that simply and effectively communicates, port cooperates lubricating cup 7, injects grease at lubricating cup 7 places; Grease arrives first axle sleeve and the second axle sleeve place respectively through oil circuit, to accomplish the lubricated of universal connector.
Need to prove that in the utility model embodiment, multidiameter shaft 2 can use other general rotating shafts to replace with gudgeon 8; Four ear hinged seats 1 or ears hinged seat 5 can use other forms of hinged seat to replace, and for example, shown in Figure 2 is a kind of alternate embodiments of the utility model embodiment, and wherein, 1 is three ear hinged seats.
Need to prove that all available self oiling bearing of first axle sleeve 3 in the foregoing description and second axle sleeve 4 replaces.
A kind of universal connector that can be used for connecting coal winning machine left and right sides two-part fuselage that the utility model embodiment provides; Through adopting a plurality of revolute pairs that coal winning machine left and right sides two-part are coupled together; Make its spatially X axle, Y axle and Z axle all have level of freedom, when the relative position of coal winning machine left and right sides two-part fuselage and angle change, regulate the relative position of coal winning machine two-part fuselage through revolute pair; Be convenient to the coal winning machine proper functioning, prevent that coal winning machine is owing to stressed excessive the damage; In addition; Owing on the axle journal of second (gudgeon), be provided with annular groove, when receiving great tensile stress between coal winning machine two-part fuselage, the gudgeon axle journal at first fractures; Avoid Coal Winning Machine stressed excessive and go to pot, thereby complete machine is played overload protective function.
The utility model embodiment also provides a kind of coal winning machine; This coal winning machine has above-mentioned universal connector; Because above-mentioned universal connector has above-mentioned technique effect; Coal winning machine with this universal connector also should possess the corresponding techniques effect, and its practical implementation process is similar to the above embodiments, does not give unnecessary details now.
