Embodiment
Please refer to Fig. 1 to Fig. 3, Fig. 1 is that supporting frame makes up 1 schematic representation according to an embodiment of the invention, and Fig. 2 is the schematic representation of the bearing combination 12 among Fig. 1, and Fig. 3 is the decomposition view of the bearing combination 12 among Fig. 2.As shown in Figure 1, supporting frame combination 1 comprises a rotating shaft 10, bearing combination 12 and one supporting frame 14.Bearing combination 12 is arranged in the rotating shaft 10.One end of supporting frame 14 is arranged in the bearing combination 12, and the other end is connected on the object and (do not illustrate), for example door-plate, display device etc.Therefore, object can rotate along with supporting frame 14 phase countershafts 10, to adjust the position that is provided with of object.
As Fig. 2 and shown in Figure 3, bearing combination 12 comprises one from moistening lining 120, one first thrust shaft block 122, one first thrust bearing 124, one first lid 126, one second thrust shaft block 128, one second thrust bearing 130 and one second lid 132.The one second end E2 that has one first end E1 and the corresponding first end E1 from profit lining 120.First thrust shaft block 122 is arranged on from moistening on the first end E1 of lining 120.First thrust bearing 124 is arranged in first thrust shaft block 122.First lid 126 is arranged on first thrust shaft block 122, and hides first thrust bearing 124.Second thrust shaft block 128 is arranged on from moistening on the second end E2 of lining 120.Second thrust bearing 130 is arranged in second thrust shaft block 128.Second lid 132 is arranged on second thrust shaft block 128, and hides second thrust bearing 130.Supporting frame 14 is arranged on a end in the rotating shaft then between first thrust shaft block 122 and second thrust shaft block 128, as shown in Figure 1.
In other words, bearing combination 12 utilizes first, second thrust shaft block 122,128 up and down to group, and utilize first, second lid 126,132 to hide respectively on first, second thrust bearing 124,130 that is arranged in first, second thrust shaft block 122,128, therefore bearing makes up 12 bottoms does not have the space, can prevent that the oil gas of lubricant oil volatilization formation and the dust that mechanism's friction forms from shedding from bearing combination 12.In addition, utilize first, second thrust shaft block 122,128 up and down to group, further lift shaft to concentricity and stationarity, and then prevent that supporting frame 14 phase countershafts 10 from producing when rotating and rock that minimizing produces dust because of friction.
Shown in the 3rd figure, first thrust bearing 124 comprises a plurality of first ceramic balls 1240, and second thrust bearing 130 comprises a plurality of second ceramic balls 1300.First ceramic balls 1240 is arranged in first thrust shaft block 122 and can rotates in first thrust shaft block 122.First lid 126 is resisted against first ceramic balls 1240.Second ceramic balls 1300 is arranged in second thrust shaft block 128 and can rotates in second thrust shaft block 128.Second lid 132 is resisted against second ceramic balls 1300.
In the present embodiment, moistening lining 120, first thrust shaft block 122, first lid 126, second thrust shaft block 128 and second lid 132 certainly all can be made by high-performance thermoplastic polymer (for example, polyether-ether-ketone).Polyether-ether-ketone is " PEEK " that is commonly called as in the general industry, is a kind of high molecular special material, high temperature resistant, resist chemical and have favorable rigidity, toughness and self-enrichment.Therefore, bearing combination 12 of the present invention need not be added any lubricant oil, can have the good characteristic of profit certainly, and does not have the problem generation of oil gas volatilization.
As shown in Figure 1, supporting frame combination 1 also can comprise one first fixed block 16, one second fixed block 18 and a jam nut 20.First fixed block 16 and second fixed block 18 all are arranged in the rotating shaft 10.First fixed block 16 has one first inner side surface 160 and one first outer side surface 162, and wherein first inner side surface 160 is adjoining in the side of first lid 126, and the limited part 100 of rotating shaft 10 is resisted against first outer side surface 162.Second fixed block 18 has one second inner side surface 180 and one second outer side surface 182, and wherein second inner side surface 180 is adjoining in the side of second lid 132.Jam nut 20 is arranged on an end of rotating shaft 10, and is resisted against second outer side surface 182.Like this, jam nut 20 and limited part 100 can limit first fixed block 16, bearing combination 12 and second fixed block 18 mutually countershaft 10 move.Use is locked or unloaded to jam nut 20 tolerables repeatedly, can bear vibration, and also can guarantee complete drag when not locking.
As shown in Figure 1, can be fixed in a plane 3 (for example, wall, ceiling board etc.) by first fixed block 16 and second fixed block 18, and make the object that is fixed on the supporting frame 14 that how different set-up modes and place can be arranged supporting frame combination 1.
Bearing combination of the present invention utilizes two thrust shaft blocks up and down to group, and utilize two lids to hide the thrust bearing that is arranged in the thrust shaft block respectively, therefore, can prevent bottom the bearing combination of the present invention that the oil gas of lubricant oil volatilization formation and the dust that mechanism's friction forms from shedding from bearing makes up.In addition, utilize two thrust shaft blocks up and down to group, further lift shaft to concentricity and stationarity, and then prevent to produce when supporting frame phase countershaft from rotating and rock, minimizing produces dust because of friction.In addition, moistening lining, thrust shaft block and lid certainly all can be made by high-performance thermoplastic polymer (for example, polyether-ether-ketone).Do not have oil from moistening characteristic because the high-performance thermoplastic polymer has, therefore do not need in the bearing combination, to add lubricant oil, avoid the lubricant oil volatilization to form oil gas.
Though should be pointed out that invention has been described by above-mentioned preferred implementation, yet the present invention also can have other numerous embodiments.Without departing from the spirit and scope of the present invention; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the present invention, but these changes and distortion all should belong in the scope that claims of the present invention and equivalent thereof protect.
