In figure: more than 1 top board, 11 top board deep-slotted chip breakers, 12 top board positioning grooves, 2 locating dowel pins, 31 rubber layer main bodys, 32 rubber layers outside limit, 33 rubber layers, 4 base plates, 41 base plate projections.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the utility model:
Embodiment one
As shown in Figure 1, rubber pad comprises top board 1, locating dowel pin 2, rubber layer and base plate 4.Top board 1, locating dowel pin 2 and base plate 4 are all made of metal, and locating dowel pin 2 is weldingly fixed on top board 1, and locating dowel pin 2 Main Function is fixed on guideway vehicle by rubber pad.And top board 1, rubber layer and base plate 4 is sulfided into an entirety by sulfuration process, when rubber pad is subject to vertical, horizontal and vertical stress, rubber layer can produce deformation counter stress and cushion, thus improves the running velocity of vehicle on straight line and curving performance.
When rubber pad is subject to stress, rubber layer can produce deformation, for the stress reducing outside rubber layer 33 is concentrated, the annular arc section that outside rubber layer, the shape of 33 preferably caves in the inside or annular flat straight section or the annular arc section protruded laterally, preferred shape is the annular arc section caved in the inside.When rubber pad is subject to stress, rubber layer can produce deformation, and outside rubber layer, the two ends of 33 are provided with limit 32 more than rubber layer, increase the area that rubber layer is combined with top board 1 and base plate 4, can prevent rubber layer from departing from top board 1 and base plate 4 by actv..
As shown in Figure 1, Figure 2 and Figure 3, the midway location of top board 1 lower end digs the top board deep-slotted chip breaker 11 of surface for sphere, and the radius of top board deep-slotted chip breaker 11 is R1, and the preferred value of R1 is 150mm-250mm, and preferred value is 200mm.The top of top board deep-slotted chip breaker 11 has through top board positioning groove 12, and locating dowel pin 2 passes top board positioning groove 12 and is weldingly fixed on top board 1.Dotted line in Fig. 3 is when not opening through top board positioning groove 12, the outline line of top board deep-slotted chip breaker 11.
As shown in Figure 4, the midway location of base plate 4 upper end is provided with the base plate projection 41 of surface for sphere, and the radius of base plate projection 41 is R2, and the preferred value of R2 is 100mm-150mm, and preferred value is 127mm.Dotted line in Fig. 4 is the boost line of the inferior portion for separating base plate projection 41 and base plate 4.
As shown in Figures 1 to 4, rubber layer comprises limit 32 more than rubber layer main body 31 and rubber layer, rubber layer main body 31 that section of rubber that to be rubber layers contact with the sphere of top board deep-slotted chip breaker 11 and base plate projection 41, and more than rubber layer, limit 32 is the rubber of rubber layer main body 31 periphery.The thickness of rubber layer main body 31 is the difference of the value of the value of the radius R 1 of top board deep-slotted chip breaker 11 and the radius R 2 of base plate projection 41, and such as, when the value that the value of R1 is 200mm, R2 is 127mm, the thickness of rubber layer main body 31 is then 73mm.
The upper end of top board 1 is the same with the lower end of base plate 4 before opening top board positioning groove 12, is all solid metal sheet, and now the cross-sectional plane of top board 1 upper end and base plate 4 lower end is all be square, the one in equilateral polygon or circle.In a rubber pad, the cross-sectional plane of top board 1 upper end and base plate 4 lower end can be identical, also can be different.
As shown in Figure 1, Figure 2 and Figure 3, because the top of top board deep-slotted chip breaker 11 also has top board positioning groove 12, and in top board positioning groove 12, locating dowel pin 2 is installed, and the bottom of locating dowel pin 2 is planes, therefore the bottom of locating dowel pin 2 is not that the top board deep-slotted chip breaker 11 of sphere forms level and smooth transition with surface, but there is little gap.Rubber layer by adhesive be sulfided into top board 1 under certain temperature and pressure one overall time, rubber layer can fill the little gap between the bottom of locating dowel pin 2 and top board deep-slotted chip breaker 11, therefore the upper end of rubber layer is not a complete sphere, but is similar to sphere.But because gap is very little, and by rubber filling, so this gap has an impact to the rigidity characteristic of rubber layer hardly.
As shown in Figure 1, the vertical cross section of rubber layer main body 31 is for there being certain thickness circular arc, and when rubber pad is subject to horizontal or longitudinal stress, the deformation that rubber layer produces is not single shear deformation, but a kind of compound deformation of shearing and compressing.This horizontal and vertical rigidity making rubber layer can provide very large, and have good buffering effect, can improve the running velocity of guideway vehicle on straight line and curving performance.
Obviously, under the prerequisite not departing from principle described in the utility model, the some improvement made or modification all should be considered as protection domain of the present utility model.
