Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.It should be noted that at this, the explanation for these mode of executions understands the utility model for helping, but does not form restriction of the present utility model.In addition, if below in described each mode of execution of the utility model involved technical characteristics do not form conflict each other and just can mutually combine.
As shown in Figure 1, running shaft 1, bearing support 2 should be comprised with the sliding bearing lifting shaft device, also comprise and lift shaft device 3, this is lifted shaft device 3 and is symmetry center with the straight line perpendicular with running shaft 1 center line, in the length range of running shaft 1, is symmetrically arranged on the both sides of bearing support 2; As shown in Figure 2, left side comprises support ear 4, lifts axle crossbeam 5, screw rod 6, adjusting nut 7, locking nut 8, two support ears 4 are distributed in the both sides of running shaft 1 and are connected with bearing support 2, locking nut 8 is connected with one end of screw rod 6, and the through hole 9 lifting axle crossbeam 5 that the other end of screw rod 6 connects through running shaft 1 time arc surface is connected with the adjusting nut 7 of support ear 4 upper-end surface with the through hole 10 of support ear 4.Technique scheme is namely by rotating adjusting nut 7, realize lifting axle crossbeam 5 promote or reduce, because lifting crossbeam 5 is connected with the lower arc surface of running shaft 1, when lifting crossbeam 5 rises under the effect of lifting crossbeam 5 by running shaft 1 lifting, because the spinning movement of rotating adjusting nut 7 can control, can need during rotating adjusting nut 7 to select arbitrary rotating cycle or angle of swing, therefore this lifting action can realize adjustable, fine setting, the displacement that running shaft 1 is larger can not be caused, the collision of component can not occur; This adjustment action easily controls, and Security is high, convenient and swift, and workload is little.
More specifically; running shaft 1 time arc surface is be connected with the lower arc surface of running shaft 1 by lifting the arc surface 11 on axle crossbeam 5 with lifting that axle crossbeam 5 is connected; make to lift axle crossbeam 5 to be fitted by arc surface with the connection of running shaft 1; guarantee that in lifting process, lift axle crossbeam 5 can not cause damage because stress is concentrated to the arc surface of running shaft 1, the surface roughness of available protecting running shaft 1 arc surface.The radius of arc lifting the arc surface 11 on axle crossbeam 5 is identical with the radius of running shaft, and there is arc-shaped transitional surface arc surface 11 and horizontal plane joint; Lift axle crossbeam 5 to be connected with running shaft 1 and to realize complete close fit and connect, make stress distribution in lifting process evenly, minimum to the infringement of running shaft 1.Support ear 4 is symmetry center with the longitudinal center line of running shaft 1, is distributed on bearing support 2 symmetrically, because support ear 4 is symmetrical, effectively can reduce in lifting process the moment of torsion lifted axle crossbeam 5 and carry.Between support ear 4 and adjusting nut 7, locking nut 8 and lift between axle crossbeam 5 and be all connected with pad 12, wearing and tearing are produced by rotating adjusting nut 7 pairs of pads 12, effectively avoid the wearing and tearing of adjusting nut 7 pairs of support ears 4 in rotary course, extend the working life of support ear 4.Also be connected with soft rubber cushion 13 lifting between the arc surface 11 of on axle crossbeam 5 and the lower arc surface of running shaft, effectively reduce the impact that produces in adjustment process to the impact of running shaft 1, especially can not simultaneously to bearing support 2 two ends lift shaft device 3 regulate time, running shaft in height can produce certain inclination, and this soft rubber cushion 13 can reduce and slow down the infringement of localized stress.The arc surface 11 lifted on axle crossbeam 5 is greater than at the width of running shaft 1 axis lifts the width of axle crossbeam 5 remaining part in running shaft 1 axis, effectively can reduce running shaft 1 and the stress lifting unit area on cylndrical surface that axle crossbeam 5 contacts, reduce the infringement to running shaft 1.
By reference to the accompanying drawings shown in 2 and accompanying drawing 3, this plain bearing bush to remove and install method specific as follows:
One is tear lid open: first the outer seal 14 of bearing, upper ball cover 15, top bearing shell 16 are taken apart, hung away.
Two be install lift shaft device: according to the interface size on bearing support 2 the two ends of bearing support 2 install lift shaft device 3, first support ear 4 is arranged on bearing support 2, then axle crossbeam 5 will be lifted through the through hole 10 of the through hole 9 and support ear 4 of lifting axle crossbeam 5 successively with screw rod 6 and be fitted and connected completely with running shaft 1.
Three is lifting running shafts: by the adjusting nut 7 of rotary support ear 4 upper end, first by lifting two adjusting nut 7 first half-twist ~ 180 ° of shaft device 3 in bearing support 2 one end, two of the other end adjusting nuts 7 should rotated equal angular during rotating adjusting nut 7; Again by adjusting nut 7 half-twist ~ 180 ° of one end, then two of the other end adjusting nuts 7 are rotated equal angular; Then in circulation, until running shaft to be lifted to the H value of 0.2mm ~ 2mm; The utility model is lifted to 1.5mm.
Four is dismounting lower bearinges: after running shaft 1 is lifted to predetermined height, lower bearing 17 can be rotated along running shaft 1, lower bearing 17 can be dismantled by the upper arc surface being turned to running shaft 1.
Five is install lower bearing: rotated along running shaft 1 by intact lower bearing 17, lower bearing 17 is screwed in bearing support 2, the adjusting nut 7 of shaft device 3 is lifted in opposite spin again, it is identical with during lifting running shaft 1 that it rotates requirement, running shaft 1 is put off on lower bearing 17, then outer seal 14, upper ball cover 15, top bearing shell 16 are recovered to install.
Below by reference to the accompanying drawings mode of execution of the present utility model is explained in detail, but the utility model is not limited to described mode of execution.For a person skilled in the art, when not departing from the utility model principle and spirit, multiple change, amendment, replacement and modification being carried out to these mode of executions, still falling in protection domain of the present utility model.
