Abstract
The utility model relates to a long pin roll anti-bending device. The long pin roll anti-bending device is characterized by comprising first lug plates (1), sleeves (4) and a second lug plate (5), wherein a long pin roll (3) penetrates through a connecting through hole in the second lug plate (5); and the sleeves (4) are sleeved outside the long pin roll (4) at the left side and the right side of the second lug plate (5) and are connected with the first lug plates (1) by virtue of transition fit. The long pin roll anti-bending device can be used for converting anti-bending load born by the pin roll into anti-shearing load as much as possible by virtue of the sleeve devices, so that the anti-shearing effect of the pin roll can be brought into full play, the anti-bending load born by the long pin roll can be reduced, and the safety in the using process of the pin roll can be guaranteed.
Description
Technical field
The utility model relates to bearing pin bending resistance field, particularly an a kind of pull back device of having strong market potential that is adapted to also need bear big moment of flexure when bearing pin bears shearing.
Background technique
Bearing pin is the fastening piece of a class standardization, but both stationary connected, and also can do relative motion with connected piece, was mainly used in the hinged place of two parts, constitutes hinge and connects, and is widely used in each side such as engineering, machinery.
The bearing pin Placement is varied, and the mode of structure of the connection of normal employing is that simple shear connects, double shear connects and is connected with many otic placodes.In the designing and calculating of bearing pin, often with bending resistance and resistance to compression as design controlled conditions, do not consider that generally bearing pin is as bending resistance component.
But the structure that some is special makes bearing pin not only need to bear pressure, cut load, also needs to bear bigger bending resistance load.Bearing pin generally is that diameter is the round member of 3mm ~ 100mm, and its module of anti-bending section is very little, and anti-bending bearing capacity is very weak.Be connected structure for common simple shear connection, double shear connection with many otic placodes, if want bearing pin to bear bending resistance load, then bearing pin is in very disadvantageous stress.
Summary of the invention
The purpose of this utility model provides a kind of pull back device of having strong market potential that can also bear big moment of flexure when can bear shearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of pull back device of having strong market potential, it is characterized in that: it comprises first otic placode, sleeve and second otic placode, the axle of having strong market potential runs through the connecting through hole on second otic placode, the outer sleeve that all is socketed with of the axle of having strong market potential of the second otic placode left and right sides, about two sleeves link to each other with first otic placode by transition fit.
Fixedly there is second stiffened plate at the described second otic placode place.
On described first otic placode first stiffened plate is arranged fixedly.
Described first stiffened plate is ring structure, and there is through hole at the middle part, and the internal diameter of middle part through hole and sleeve outer diameter satisfy the requirement of transition fit, makes first stiffened plate, first otic placode and sleeve constitute overall structure.
Fixing many group first stiffened plates in the described first otic placode inwall place.
The beneficial effects of the utility model are: this pull back device of having strong market potential is by adopting sleeve means, the bending resistance load that bearing pin is born converts the shearing resistance load to as much as possible, give full play to the shearing resistance effect of bearing pin, reduce the bending resistance load that it bears, guarantee the safety of bearing pin using process.
Description of drawings
Below in conjunction with embodiment's accompanying drawing the utility model is further specified:
Fig. 1 is that bearing pin connects planimetric map;
Fig. 2 is that bearing pin connects elevation.
Among the figure: 1, first otic placode; 2, first stiffened plate; 3, the axle of having strong market potential; 4, sleeve; 5, second otic placode; 6, second stiffened plate.
Embodiment
Embodiment 1
As shown in Figure 1, originally a pull back device of having strong market potential comprises first otic placode 1, sleeve 4 and second otic placode 5, axle 3 connecting through holes that run through on second otic placode 5 of having strong market potential, the axle 3 outer sleeves 4 that all are socketed with of having strong market potential of second otic placode, 5 left and right sides, about the outside of two sleeves 4 connect first otic placode 1 by transition fit.
As shown in Figure 2, during use, second otic placode, 5 places fixedly have second stiffened plate 6 usually, second otic placode 5 is played the effect of putting more energy into, because the existence of second stiffened plate 6 is arranged, and can not cut off, cause that the axle of having strong market potential is 3 long, the axle 3 that causes having strong market potential should shearing resistance be born very big bending resistance load again, therefore after the axle 3 of having strong market potential passes the connecting through hole of second otic placode 5, at its left and right sides socket sleeve 4, link to each other by sleeve 4 outsides and 1 transition of first otic placode coupling again, with the have strong market potential moment of flexure of axle 3 of elimination, take full advantage of spools 3 the shear behavior of having strong market potential.
Embodiment 2
As shown in Figure 1, for guaranteeing the building-in depth of sleeve 4 in first otic placode 1, satisfy force request, at first otic placode 1 first stiffened plate 2 is arranged fixedly.
First stiffened plate 2 is ring structure, there is through hole at the middle part, the internal diameter of middle part through hole and the requirement that sleeve 4 external diameters satisfy transition fit make first stiffened plate 2, first otic placode 1 and sleeve 4 constitute overall structure, can fix many group first stiffened plates 2 at first otic placode, 1 inwall place according to actual conditions.
The parts that present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
