The specific embodiment
Fig. 1 to Fig. 4 shows respectively the structural representation of quiet according to the preferred embodiment of the invention carrying roller bearing assembly and quiet carrying roller.In Fig. 4, quiet carrying roller comprises roll body 1, runs through roller carrier shaft 2 and the bearing assembly of roll body 1 along described roll body 1 rotation axis, this bearing assembly at least comprises: bearing seat 3, bearing 4, bottom sealing ring 5, axle sleeve 8, sleeve sealing circle 9 and sealing external cover 10, as shown in Figure 1.
Roll body 1 is cylindric, and the modified ultra-high molecular weight polyethylene tubing of employing take ultra-high molecular weight polyethylene as main material is via an extrusion molding of extruder.The roll body 1 that adopts superhigh molecular weight polyethylene material to make has high impact properties, high-wearing feature, and resistance to corrosion, self lubricity, non-scaling, weather resisting property and resistance to aging, thermophily is wide, advantage lightweight, easy for installation.
Roller carrier shaft 2 runs through roll body 1 along roll body 1 rotation axis.Roller carrier shaft 2 is steel axle, is preferably cold-drawn round steel.The roller carrier shaft 2 that adopts cold-drawn round steel to make has that precision is high, intensity is high, and toughness is strong, and surface quality is good, reduces radial run-out, rotational resistance, is difficult for the hurtful advantage of bearing, and the smooth rotation of carrier roller integral is played to decisive role.
Bearing assembly is arranged at two ends of roll body 1, and for each end, bearing assembly is configured to press fit into roll body 1 from the end of roll body 1 towards the middle part of roll body 1.For convenience of description, only an end in two of roll body 1 ends is described, the structure of another end not describing is corresponding with the structure of the end that this will describe.Therefore, those skilled in the art can understand, following all explanations are all one of them ends for roll body 1, this is not construed as limiting the invention, and those skilled in the art do not carry out can understanding in the situation of any creative work the structure of two ends of roll body 1 by being described in of this one of them end to roll body 1.
In the end of roll body 1 Fitted Axles bearing 3, bearing 4 is arranged in bearing seat 3.Bearing seat 3 adopts polypropylene, ABS or nylon material injection moulding to form.Especially, when adopting when nylon material, carrying roller smooth running and there is the voice that is low to moderate 3-7dB, and the 3-5 that the life-span of carrying roller reaches the metal roller life-span is doubly.Bearing 4 is the special nylon cages bearing of large play carrying roller.This bearing 4 has lightweight, and noise is low, wear-resisting, antimagnetic, and the friction between low friction and minimizing retainer and rolling body is effectively to extend the bearing advantage in 4 service lifes.
Referring to Fig. 1 to Fig. 4, bottom sealing ring 5 is along a side that is axially set in bearing 4 of roll body 1, with respect to the side at the more close roll body of bearing 41 middle part.Bottom sealing ring 5 adopts elastic body, PVC or elastomeric material injection moulding to form, and it effectively prevents that sand, dust, steam etc. from entering the inside of quiet carrying roller, avoids quiet carrying roller to cause damage.
Axle sleeve 8, sleeve sealing circle 9 and sealing external cover 10 be along the opposite side that is axially set in bearing 4 of roll body 1, with respect to a side of the more close roll body of bearing 41 end.Axle sleeve 8 is sleeved on roller carrier shaft 2, and extends certain distance in the axial direction of roll body 1, and a side of the close bearing 4 of axle sleeve 8 extends radially outward certain altitude.Sleeve sealing circle 9 is made up of four little sleeve sealing circles, each little sleeve sealing circle adopts elastic body, PVC or elastomeric material injection moulding to form, described four little sleeve sealing circles with axle sleeve 8 coaxial and along roll body 1 axially successively arrange, the lip limit of four little sleeve sealing circles can form the outpost of the tax office, longitudinal Si road.The certain altitude that aforementioned axle sleeve 8 extends radially outward in a side of the upwardly extending certain distance of axle of roll body 1 and the close bearing 4 of axle sleeve 8 meets this distance and height can hold above-mentioned four little sleeve sealing circles, thereby between axle sleeve 8 and sleeve sealing circle 9, forms actv. level Four sealing.So,, because roller carrier shaft 2 is little with the friction force of axle sleeve 8, alleviated the rotational resistance of carrying roller.In addition, the design actv. of level Four sealing has hindered entering of dust, the globule, has reduced the infringement to bearing, has guaranteed the running that carrying roller can be long-time, high-speed.
Between axle sleeve 8 and four little sleeve sealing circles, fill No. 2 greases of lithium base.Owing to having formed sealing between axle sleeve 8 and four little sleeve sealing circles, the grease of therefore filling exists with the form of permanent seal, makes carrying roller during use without supplemental lubrication fat again.Noise is low in the course of the work, rotational resistance is little for carrying roller, smooth running, reach traditional carrying roller service life 2-3 doubly.
This specification sheets is illustrated take four little sleeve sealing circles as preferred embodiment, but it will be appreciated by those skilled in the art that, this is only exemplary, in some cases, can comprise still less or more little sleeve sealing circle, for example, be equipped with five little sleeve sealing circles, thereby form Pyatyi sealing.
Sealing external cover 10 adopts polypropylene, ABS or nylon material injection moulding to form, and is arranged to axle sleeve 8 coaxial.
Quiet according to the preferred embodiment of the invention carrying roller also comprises enhancing cover 6, strengthens cover 6 and closely cooperates with bearing 4.Fig. 3 is the structural representation that strengthens cover, as shown in Figure 3, strengthen cover 6 flanges 62 that there is annular base portion 61 and extend to form in the direction perpendicular to base portion 61 from the outer peripheral edges of base portion 61, when installation, this flange 62, for being the part of radially extending along the axially extended part base portion 61 of roll body 1, has occupied the space between bottom sealing ring 5 and bearing 4 and between bearing seat 3 and bearing 4.Strengthening cover 6 adopts nylon resin or polytetrafluoroethylmaterial material injection moulding to form.In flange 62, form in the same way multiple auxiliary holes 63 with flange 62, particularly, auxiliary hole 63 extends to base portion 61 from the end of flange 63.The enhancing cover 6 forming so has not only improved the weakness of bearing seat 3 insufficient strength, and the auxiliary hole 63 that strengthens cover 6 can also play the noise that weakens roller carrier shaft 2 and bearing 4 and rub, shake generation.
Quiet according to the preferred embodiment of the invention carrying roller also comprises shaft block ring 7, and it is arranged between bearing 4 and axle sleeve 8, for bearing 4 is carried out to axial restraint.
When assembling, first roll body 1 is positioned on bench board, bearing seat 3 is pressed fit into roll body 1, then successively bottom sealing ring 5, enhancing cover 6, bearing 4 are placed into and are press-fited on arbor, fix roller carrier shaft 2, by bottom sealing ring 5, strengthen cover 6 and bearing 4 one steps are press-fit into place, then load onto jump ring (not shown, adopt 65MN
springsteel making) position, sleeve sealing circle 9, the sealing external cover 10 of afterwards axle sleeve 8 and painting being spread to grease 11 press-fit, and so far complete whole assembling process.
In general, in appending claims, term used should not be interpreted as this claim to be restricted to disclosed specific embodiment in specification sheets and claims, and should be interpreted as the four corner that is equal to means that comprises that all possible embodiment and such claims comprise.
