In figure, be labeled as: support 1, roller bearing 2, pin-and-hole 3, transmission shaft 4, decompression rod 5, support 6, outstanding bar 7, connecting shaft 8, projecting block 9, clad 10, raised face 11, interface 12, ball 13, lid shell 14.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figures 1 to 4, a kind of movable roller, comprises that one can be installed on the support 1 of device bottom and the roller bearing 2 being connected with support 1, and support 1 sidepiece has the pin-and-hole 3 running through, and the inwall of pin-and-hole 3 is circumferentially evenly equipped with some outstanding bars 7 along it.Pin-and-hole 3 places have the transmission shaft 4 that can rotate, and transmission shaft 4 comprises connecting shaft 8 and the some projecting blocks 9 that is circumferentially distributed in connecting shaft 8 sidepieces that is column, are provided with decompression rod 5 between projecting block 9 and outstanding bar 7.Described decompression rod 5 is PU compressed rod, and the outside of roller bearing 2 is coated with one deck clad 10, and clad 10 is made by elastomeric material.
The two ends of described transmission shaft 4 are fixed with support 6, and the sidepiece of support 6 has raised face 11, and raised face 11 is resisted against the port of pin-and-hole 3, are provided with some balls 13 between the port of pin-and-hole 3 and support 6.On raised face 11, have the interface 12 identical with connecting shaft 8 cross sectional shapes, the end of connecting shaft 8 embeds in interface 12, and support 6 is connected by a screw through interface 12 and connecting shaft 8 mutually with transmission shaft 4.In the present embodiment, be also fixed with can be by the coated lid shell 14 of roller bearing 2 sidepieces in the outside of support 6.
Described movable roller when mounted, transmission shaft 4 is put into pin-and-hole 3, and between the projecting block 9 of transmission shaft 4 and the outstanding bar 7 of pin-and-hole 3, put into decompression rod 5, and then the interface 12 of raised face 11 on support 6 is aimed at respectively to insertion with the end, two ends of connecting shaft 8 on transmission shaft 4, recycling screw is fixed together support 6 and transmission shaft 4.The raised face 11 of support 6 can be resisted against the port of pin-and-hole 3, in order to facilitate the rotation of support 6, can place ball 13 at the sidepiece of raised face 11, and make ball 13 between support 6 and pin-and-hole 3 ports.
As shown in Figure 3, the present invention is installed on device bottom by support 1, under the Action of Gravity Field of equipment self, make at the projecting block 9 of transmission shaft 4 and the decompression rod 5 between the outstanding bar 7 on the pin-and-hole 3 inwalls state in a pretension compression all the time, like this when equipment can not produce larger vibrations and noise during in movement yet.
As shown in Figure 4, and the weight of working as on equipment increases weight suddenly, when causing acting on impulsive force in movable roller and increasing suddenly, equipment and support 1 together sink, cause roller bearing 2 and support 6 to be pressed downward, the rotation that support 6 causes transmission shaft 4 to produce certain angle in the process to pressing down, decompression rod 5 is further compressed, because decompression before excellent 5 has been in a compressed state, therefore the counteraction that now 5 pairs of these impulsive forces of decompression rod produce is larger, be that energy-absorbing function is more obvious, energy-absorbing effect is better.Meanwhile, the clad 10 that is coated on roller bearing 2 outsides also can play energy-absorbing function to a certain extent when roller bearing 2 is pressed down.
The present invention utilizes the self gravitation effect of equipment the rod that reduces pressure to be played to the effect of a pretension compression, make decompression rod to produce good energy-absorbing function by the impulsive force in movable roller to momentary action, impact-absorbing and vibrations in time, have also extended the service life of movable roller simultaneously; The arranged outside clad of described roller bearing comes to coordinate with decompression rod the effect that forms Double-energy-absorption, and energy-absorbing effect is better, possesses higher practical value and wider applicability; The described PU compressed rod of utilizing, as decompression rod, by the good Combination property of PU rod, has increased energy-absorbing scope of the present invention, the rod generation effect in time of guaranteeing to reduce pressure.Therefore simple structure of the present invention, energy-absorbing effect is good and can effectively reduce pressure.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
