Wear-resistant sleeve is the cirque structure that an end is provided with round flange in said, and the inboard of said round flange is provided with the round flange groove.
Said outer wear-resistant sleeve is a cirque structure, and the excircle of wear-resistant sleeve has circular groove outside ring is said, and said circular groove is positioned at the middle part of said outer wear-resistant sleeve, and said outer wear-resistant sleeve filling passage is positioned at said circular groove.
Said fixed cover is a cirque structure, and the inboard of said ring fixed cover is provided with circular groove.
The advantage of the utility model is; After using the utility model anti-friction bearing; It is lubricated to adopt the oiling formula to slide between wear-resistant sleeve and the interior wear-resistant sleeve outside, has reduced the frictional force between interior wear-resistant sleeve and the outer wear-resistant sleeve, guarantees the smooth operation of equipment; The repair rate that makes equipment extends to 4 months by former 1 time/month, has practiced thrift a large amount of costs of overhaul every year; And similarly also promoting in the equipment; Simultaneously promoting effect has also been played in the environmental improvement work at scene, having reduced in the past stops after the damage of bearings runs grey phenomenon.
Description of drawings
Fig. 1 is a kind of anti-friction bearing structural drawing that is used to struggle against and carries tail wheel.
Interior wear-resistant sleeve 1, outer wear-resistant sleeve 2, fixed cover 3, bearing support 4, tail-gear spindle 5, outer wear-resistant sleeve filling passage 6, fuel filler neck 7, circular groove 8, circlip for hole 9, round flange 10, round flange groove 11, circular groove 12, bearing support filling passage 13.
Embodiment: a kind of be used to struggle against carry the anti-friction bearing of tail wheel, it comprises interior wear-resistant sleeve 1, outer wear-resistant sleeve 2, fixed cover 3 and bearing support 4, in outer wear-resistant sleeve 2 is sleeved on outside the wear-resistant sleeve 1; And be slidingly connected with interior wear-resistant sleeve 1, the gap between outer wear-resistant sleeve 2 and the interior wear-resistant sleeve 1 is filled with lubricant oil, and interior wear-resistant sleeve 1 is sleeved on the tail-gear spindle 5; And with tail-gear spindle 5 interference fit, the axle head of tail-gear spindle 5 is set with fixed cover 3, tail-gear spindle 5 and fixed cover 3 interference fit; The exterior edge face of the inboard of fixed cover 3 and interior wear-resistant sleeve 1 fits; Outer wear-resistant sleeve 2 is sleeved in the bearing support 4, and is connected with bearing support 4 interference fit, radially is provided with bearing support filling passage 13 along bearing support 4; Radially be provided with outer wear-resistant sleeve filling passage 6 along outer wear-resistant sleeve 2; Bearing support filling passage 13 is corresponding with outer wear-resistant sleeve filling passage 6, and bearing support filling passage 13 is provided with fuel filler neck 7, and fuel filler neck 7 is positioned at bearing support 4 outer walls one end; The both sides of outer wear-resistant sleeve 2 are respectively equipped with circlip for hole 9, play the positioning action of external wear-resistant sleeve 2.
Interior wear-resistant sleeve 1 is the cirque structure that an end is provided with round flange 10, and the inboard of round flange 10 is provided with round flange groove 11.When equipment ran well, tail-gear spindle had the axial float phenomenon, and the round flange on the interior wear-resistant sleeve 1 can prevent the axial float of tail-gear spindle; The frictional force of wear-resistant sleeve 1 end face and outer wear-resistant sleeve 2 end faces in the round flange groove can reduce, and the round flange inside grooves can storing lubricating oil.
