4, connect the through hole that otic placode is provided with affixed outer ring, through hole socket outer ring, another flat two glands that set cover two sides of ear connecting plate and outer ring in succession, then by bolt interlocking two glands, attaching fast and easy, intensity is high;
5, fixedly between otic placode and axle sleeve, be provided with lubricating sleeve, have corrosion-resistant, chemically-resistant material, not aging, high strength, impermeable, the grease proofing effects such as water of refusing;
6, bearing pin two ends are established and are threaded, and facilitate the adjusting of elastomeric pre-load amount, can make again node more attractive in appearance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 has illustrated sectional view of the present invention.
The specific embodiment
Shown in Fig. 1, with the plain radial bearing slippage node of reset function, it comprise a plain radial bearing 50, a bearing pin 33, two fixedly otic placode 30, connect otic placode 60 and two elastic bodys 11.
This plain radial bearing 50 comprises an inner ring 52 and an outer ring 51, this inner ring 52 is installed in 51 inner chambers of outer ring, these inner ring 52 external surfaces are provided with spherical outside surface, this outer ring 51 is provided with the Internal Spherical Surface suitable with the spherical outside surface of inner ring 52, and this inner ring 52 is connected with outer ring 51 and forms sphere formula joint motion and is connected.
This bearing pin 33 has the extension that a mid portion and two is positioned at two sides that pars intermedia divides, between described mid portion and extension, form convex shoulder, that is to say that the diameter that described extension divides is less than the diameter that described pars intermedia divides, and the end that described two extensions divide is established screw thread.
These two fixedly otic placode 30 parallel interval settings and all establish a through hole, the described two fixedly deads in line of the through hole of otic placode 30.
This connection otic placode 60 is provided with through hole.
The outer surface of revolution at the fixedly sleeved middle part at bearing pin 33 mid portions of this inner ring 52.
Through hole socket outer ring 51 that this connects otic placode 60, separately sets two glands 15 and covers two sides of ear connecting plate 60 and outer ring 51 in succession, then by bolt 14 interlocking two glands 15, with this, connection otic placode 60 and outer ring 51 are connected.
Two extensions of this bearing pin 33 respectively through two fixedly otic placode 30 through hole and stretch out, another: the moving gear 12 that socket can be slided to axial respectively on two extensions, the internal diameter of described moving gear 12 and the external diameter of extension are suitable, and the external diameter of described moving gear 12 is greater than the diameter of through hole; On two extensions, be socketed respectively again elastic body 11; The solid gear 10 of socket on extension again, then interlocking nut 20, and the cooperation by nut and extension is to locate solid gear 10, and to avoid solid gear 10 to depart from extensions, and solid gear leans connected nut 20 all the time under elastic body 11 effects.
Best, this bearing pin 33 and fixedly also establish axle sleeve 31 between otic placode 30, axle sleeve 31 2 ends are contact inner ring 52 and moving gears 12 respectively.The affixed bearing pin 33 of axle sleeve 31, and, axle sleeve 31 and fixedly establish lubricating sleeve 32 between otic placode 30.
This elastic body 11 is butterfly spring sheet, and it connects bearing pin 33 so that can be out of shape generation distortion elastic force after plain radial bearing 50 slippages, and this distortion spring energy makes plain radial bearing 50 reduction of spondylolisthesis.
Among the present embodiment, described elastic body is arranged between moving gear and solid gear, but not as limit, and as required, described elastic body also can be directly arranged in and connects otic placode and fixedly between otic placode, also can be set directly at solid gear 10 and fixedly between otic placode 30.
The specific embodiment of the present invention can produce following technique effect: a, connect the transmission of the suffered axial force of otic placode by plain radial bearing, axle sleeve, moving gear, solid gear is converted into elastic body energy storage and self kinetic energy, can slow down the suffered impact of whole node, extend node application life, increase bearing capacity; B, elastic body not only can absorb and connect the suffered impact of otic placode, extend node application life, and can also impel and connect otic placode and automatically reset, and make to connect otic placode depart from normal operation position to avoid for a long time repeatedly skidding distance stack; The plain radial bearing of c, the attaching of connection otic placode makes to connect otic placode can be when slippage, and relatively fixedly otic placode is done the motion of inclination aligning, to eliminate the additional bending moment that connects otic placode, guarantees that node security is reliable.
Among another preferred embodiment, it is with a upper preferred embodiment difference: it comprise one fixedly otic placode be connected otic placode with one, described elastic body is arranged on fixedly otic placode and connects between otic placode,
Among another preferred embodiment, it is with a upper preferred embodiment difference: it comprise three fixedly otic placode be connected otic placode with two, described two elastic bodys are arranged on and are positioned at outermost two fixedly outside otic placode, and described two connect otic placodes and are separately positioned on adjacent fixedly between otic placode.
The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
