Abstract
The utility model discloses a kind of rib type bearing bush structure, the sheet axle sleeve that this bearing bush structure integrally casting is shaping, this bearing shell outwardly side extends to form be positioned at bearing shell outer surface many with bead structures, and between adjacent rib, form groove structure, and in each groove, be embedded with Stamping Steel Ribbon, and then form the bearing shell with sealing configuration.The utility model increases the groove structure of embedding sealing bar outside bearing shell, and this groove and bearing shell one, and then increase the stability of Stamping Steel Ribbon, thus effectively increase sealing effect; Stamping Steel Ribbon for having flexible soft bar body, thus effectively alleviates the collision between mechanical part, and then guarantees the working life of parts.
Description
Technical field
The utility model relates to a kind of bearing bush structure, especially a kind of rib type bearing bush structure.
Background technique
In machinery industry, fixing bearing shell is on the rotary shaft all the semicircle sheet of tiles.When running shaft rotates, between bearing shell and running shaft, have the lubricant oil of lubricate, and on bearing shell, cover there are parts.Because running shaft is High Rotation Speed ceaselessly, produce a large amount of heats, when bar border temperature is also higher, often due to insufficient lubrication, and to have made between bearing shell and running shaft with regard to direct friction.So long-time friction can produce very high temperature, if add lubricant oil not in time, be easy to burn out bearing shell, that will damage other parts, cause mechanical disorder, its intermediate bushing is generally fixed by the mode that machinery is fixing, seals the not good steadiness that causes poor between mechanical part, between parts, motion collides and causes parts damages simultaneously.
Thus, the present inventor considers to improve existing bearing bush structure, and this case produces thus.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of rib type bearing bush structure, has rib outside it, and forms the groove structure of accommodating Stamping Steel Ribbon between adjacent rib, and then forms buffer structure.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of rib type bearing bush structure, the sheet axle sleeve that this bearing bush structure integrally casting is shaping, this bearing shell outwardly side extends to form be positioned at bearing shell outer surface many with bead structures, and between adjacent rib, form groove structure, and in each groove, be embedded with Stamping Steel Ribbon, and then form the bearing shell with sealing configuration.
Further, described Stamping Steel Ribbon is for having flexible soft bar, thus coupled counter structure coordinates formation buffer structure.
Further, described Stamping Steel Ribbon is rubber strip.
Further, described bearing shell madial wall offers V-arrangement oil guide slot.
Further, described bearing shell comprises basic unit, alloy-layer, nickeling layer, polynary nickeling layer and top layer nickeling layer from outside to inside successively.
Further, described basic unit is copper-lead layer or low tin layers.
Further, described alloy-layer is CuPb
24sn layer or AlSn
6cu layer.
Further, described nickeling layer and top layer nickeling layer are nickel plating and form coating.
Further, described polynary nickeling layer is Pb-Sn-Cu layer or b-Sn-Ln-Cu layer.
Compared with prior art, advantage of the present utility model:
1, the utility model increases the groove structure of embedding sealing bar outside bearing shell, and this groove and bearing shell one, and then increase the stability of Stamping Steel Ribbon, thus effectively increase sealing effect;
2, the Stamping Steel Ribbon in the utility model for having flexible soft bar body, thus effectively alleviates the collision between mechanical part, and then guarantees the working life of parts;
3, the utility model increases the structure of oil guide slot on bearing shell madial wall, thus guarantees the water conservancy diversion of lubricant oil.
4, in every sheet arc tile, polynary nickeling layer is increased, and then make tile have higher fatigue strength and impact resistance, be applicable to the main axle bush, connecting rod bearing shell etc. of high speed, heavy duty, there is block resistance and fatigability simultaneously, good stability when there is when high load lower temperature and low temperature.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model sectional view working state figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to shown in Fig. 1 and Fig. 2, a kind of rib type bearing bush structure, the sheet axle sleeve that this bearing bush structure integrally casting is shaping, this bearing shell 1 outwardly side extends to form be positioned at bearing shell outer surface many with rib 11 structure; Described bearing shell madial wall offers V-arrangement oil guide slot 2.
Refer to shown in Fig. 1 and Fig. 2, form groove structure between aforementioned adjacent rib 11, and in each groove, be embedded with Stamping Steel Ribbon 3, and then form the bearing shell with sealing configuration, described Stamping Steel Ribbon 3 is for having flexible soft bar, thus coupled counter structure coordinates formation buffer structure.
Refer to shown in Fig. 1 and Fig. 2, aforementioned bearing shell 1 comprises basic unit 111, alloy-layer 112, nickeling layer 113, polynary nickeling layer 114 and top layer nickeling layer 115 from outside to inside successively, and described basic unit 111 is copper-lead layer or low tin layers, and described alloy-layer 112 is CuPb
24sn layer or AlSn
6cu layer, described nickeling layer 113 and top layer nickeling layer 115 are coating that nickel plating is formed, and described polynary nickeling layer 114 is Pb-Sn-Cu layer or b-Sn-Ln-Cu layer.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
