Among one preferred embodiment: said connection otic placode and fixedly otic placode all be steel-casting.
The present technique scheme is compared with background technology, and it has following advantage:
1, engaging lug strip movable joint bearing ability relative fixed otic placode slippage; And can automatically reset after cooperating elastic body to make the relative slippage of connection otic placode with oscillating bearing; Then: a, the suffered axial force of connection otic placode are converted into elastic body energy storage and self kinetic energy through transmission such as plain radial bearings; Can slow down the suffered impact of whole node, prolong node application life, increase bearing capacity; B, elastic body not only can absorb and connect the suffered impact of otic placode, prolong node application life, and can also impel and connect otic placode and automatically reset, and make to avoid for a long time repeatedly the skidding distance stack to connect otic placode and depart from normal operation position; C, the plain radial bearing that connects the otic placode attaching make connect otic placode can be when slippage, the relative fixed 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.
2, elastic body socket extension and support is located between solid gear and the moving gear, then can avoid influencing the annexation between inner ring and the outer ring because of elastic body acts directly on inner ring, and otic placode damages fixedly otic placode and then can avoid elastic body to act directly on fixedly;
3, two extensions of bearing pin all establish outer big stepped in little, the moving adaptive socket extension of gear small diameter portion, then moving gear can play position-limiting action;
4, connect the through hole that otic placode is provided with affixed outer ring, through hole socket outer ring, flat in addition two glands that set cover two sides of ear connecting plate and outer ring in succession, and again through bolt interlocking two glands, then attaching is fast convenient, the intensity height;
5, fixedly be provided with lubricating sleeve between otic placode and the axle sleeve, have corrosion-resistant, the chemically-resistant material, aging, high strength, impermeable, the grease proofing effect such as water of refusing;
6, the bearing pin two ends are established and are threaded, and the adjusting of convenient elastomeric pre-load amount can make node more attractive in appearance again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 has illustrated sectional view of the present invention.
The specific embodiment
In conjunction with shown in Figure 1, the plain radial bearing slippage node of band reset function, it comprises a plain radial bearing 50, a bearing pin 33, two fixedly otic placode 30, a connection 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 and the suitable Internal Spherical Surface of 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 of pars intermedia branch; Form convex shoulder between said mid portion and the extension; That is to say the diameter of the diameter of said extension branch, and the end of said two extension branches is established screw thread less than said pars intermedia branch.
These two fixedly otic placode 30 parallel interval settings and all establish a through hole, the said 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.
This connects the through hole socket outer ring 51 of otic placode 60, and other sets two glands 15 and covers two sides of ear connecting plate 60 and outer ring 51 in succession, again through bolt 14 interlockings two glands 15, will connect otic placode 60 and outer ring 51 is connected with this.
Two extensions of this bearing pin 33 pass respectively two fixedly otic placode 30 through hole and stretch out; In addition: the socket moving gear 12 that can slide to axial respectively on two extensions; The internal diameter of said moving gear 12 and the external diameter of extension are suitable, and the external diameter of said moving gear 12 is greater than the diameter of through hole; On two extensions, distinguish socket elastic body 11 again; The solid gear 10 of socket on extension again, the interlocking nut 20 then, and the cooperation through nut and extension breaks away from extensions to locate solid gear 10 to avoid solid gear 10, and under elastic body 11 effects, consolidates gear and lean connected nut 20 all the time.
Best, this bearing pin 33 and fixedly also establish axle sleeve 31 between the otic placode 30, axle sleeve 31 2 ends push up respectively to inner ring 52 and moving gear 12.Axle sleeve 31 affixed bearing pins 33, and, axle sleeve 31 and fixedly establish lubricating sleeve 32 between the otic placode 30.
This elastic body 11 is the 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 elastic force can make plain radial bearing 50 reduction of spondylolisthesis.
Among the present embodiment, said elastic body is arranged between moving gear and the solid gear, but not as limit, and as required, said elastic body also can be directly arranged in and connects otic placode and fixedly between the otic placode, also can be set directly at solid gear 10 and fixedly between the 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 through 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; Prolong node application life, increase bearing capacity; B, elastic body not only can absorb and connect the suffered impact of otic placode, prolong node application life, and can also impel and connect otic placode and automatically reset, and make to avoid for a long time repeatedly the skidding distance stack to connect otic placode and depart from normal operation position; C, the plain radial bearing that connects the otic placode attaching make connect otic placode can be when slippage, the relative fixed 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 last preferred embodiment difference: it comprise one fixedly otic placode be connected otic placode with one, said elastic body is arranged on fixedly otic placode and connects between the otic placode,
Among another preferred embodiment; It is with a last preferred embodiment difference: it comprise three fixedly otic placode be connected otic placode with two; Said two elastic bodys are set in place in outermost two fixedly outside the otic placode, and said two connect otic placodes and are separately positioned between the adjacent fixed otic placode.
The above is merely preferred embodiment of the present invention, so can not limit the scope that the present invention implements according to this, the equivalence of promptly doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
