Detailed description of the invention
Fig. 1 to Fig. 4 respectively illustrates carrying roller bearing assembly and the structural representation of carrying roller according to the preferred embodiment of the invention.In the diagram, carrying roller includes 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 includes: bearing block 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 cylindrical, uses the modified ultra-high molecular weight polyethylene tubing with ultra-high molecular weight polyethylene as main material via extrusion molding of extruder.The roll body 1 using superhigh molecular weight polyethylene material to make has high impact properties, high-wearing feature, corrosion resistance, self lubricity, non-scaling, weatherability and ageing resistance, thermophily width, 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, preferably cold-drawn round steel.Precision is high, intensity is high to use the roller carrier shaft 2 made of cold-drawn round steel to have, and toughness is strong, and surface quality is good, reduces radial run-out, rotational resistance, is difficult to countershaft hold hurtful advantage, and the smooth rotation overall to carrying roller plays decisive role.
Bearing assembly is arranged at two ends of roll body 1, and for every one 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.Describing for convenience, only illustrate an end in two ends of roll body 1, the structure of another end not illustrated is corresponding with the structure of the end that this will illustrate.Therefore, skilled artisans appreciate that, following is described one of them end being both for roll body 1, this is not construed as limiting the invention, those skilled in the art by this to one of them end of roll body 1 be described in do not carry out any creative work in the case of will appreciate that the structure of two ends of roll body 1.
In the end Fitted Axles bearing 3 of roll body 1, bearing 4 is arranged in bearing block 3.Bearing block 3 uses polypropylene, ABS or nylon material injection to be formed.Especially, when using nylon material, carrying roller smooth running and there is the voice of as little as 3-7dB, and the life-span of carrying roller is up to 3-5 times of the metal roller life-span.Bearing 4 is the nylon cages bearing that big play carrying roller is special.This bearing 4 has lightweight, and noise is low, wear-resisting, antimagnetic, and the friction between low friction and minimizing retainer and rolling element is with the advantage effectively extending bearing 4 service life.
Seeing Fig. 1 to Fig. 4, bottom sealing ring 5 is along the side being axially set in bearing 4 of roll body 1, i.e. relative to bearing 4 closer to the side in the middle part of roll body 1.Bottom sealing ring 5 uses elastomer, PVC or elastomeric material injection to be formed, and it effectively prevents sand, dust, steam etc. from entering the inside of carrying roller, it is to avoid carrying roller is caused damage.
Axle sleeve 8, sleeve sealing circle 9 and sealing external cover 10 are along the opposite side being axially set in bearing 4 of roll body 1, i.e. relative to bearing 4 closer to the side of roll body 1 end.Axle sleeve 8 is sleeved on roller carrier shaft 2, and extends a distance up at the axle of roll body 1, and the 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 uses elastomer, PVC or elastomeric material injection to be formed, described four little sleeve sealing circles are coaxial with axle sleeve 8 and being axially sequentially arranged along roll body 1, and the lip of four little sleeve sealing circles can form the four longitudinal outposts of the tax office, road.Aforementioned axle sleeve 8 meets this distance and height can accommodate aforementioned four little sleeve sealing circle at the certain altitude that the side of the upwardly extending certain distance of axle of roll body 1 and the close bearing 4 of axle sleeve 8 extends radially outward, thus forms effective level Four sealing between axle sleeve 8 and sleeve sealing circle 9.So, owing to roller carrier shaft 2 is little with the frictional force of axle sleeve 8, the rotational resistance of carrying roller is alleviated.It addition, the design of level Four sealing effectively hinders the entrance of dust, the globule, reduce the infringement to bearing, it is ensured that carrying roller can long-time, the operating of high speed.
No. 2 greases of lithio are filled between axle sleeve 8 and four little sleeve sealing circles.Owing to defining sealing between axle sleeve 8 and four little sleeve sealing circles, the grease therefore filled is presented in permanent seal so that carrying roller is during use without being supplemented with grease.Carrying roller noise in the course of the work is low, rotational resistance is little, smooth running, service life is up to 2-3 times of conventional idler.
This specification is illustrated with four little sleeve sealing circles for preferred embodiment, but it will be appreciated by those skilled in the art that, this is merely exemplary, in some cases, less or more little sleeve sealing circle can be comprised, such as, it is equipped with five little sleeve sealing circles, thus forms Pyatyi sealing.
Sealing external cover 10 uses polypropylene, ABS or nylon material injection to be formed, and is arranged to coaxial with axle sleeve 8.
Carrying roller also includes strengthening set 6 according to the preferred embodiment of the invention, strengthens set 6 and closely cooperates with bearing 4.Fig. 3 is the structural representation strengthening set, as shown in Figure 3, strengthen set 6 there is the base portion 61 of annular and upwardly extend the flange 62 of formation from the outer peripheral edge of base portion 61 in the side being perpendicular to base portion 61, during installation, for the axially extended part along roll body 1, base portion 61 is the part radially extended to this flange 62, occupies the space between bottom sealing ring 5 and bearing 4 and between bearing block 3 and bearing 4.Strengthen set 6 employing nylon resin or polytetrafluoroethylmaterial material injection is formed.Forming multiple fabrication hole 63 in the same direction with flange 62 in flange 62, specifically, fabrication hole 63 extends to base portion 61 from the end of flange 63.So formed strengthens the weakness that set 6 not only improves bearing block 3 insufficient strength, strengthens the fabrication hole 63 of set 6 and may also operate as weakening roller carrier shaft 2 and bearing 4 rubs, shakes the noise of generation.
Carrying roller also includes shaft block ring 7 according to the preferred embodiment of the invention, and it is arranged between bearing 4 and axle sleeve 8, for bearing 4 is carried out axial restraint.
During assembling, first roll body 1 is positioned on workbench, bearing block 3 is pressed fit into roll body 1, the most successively bottom sealing ring 5, enhancing set 6, bearing 4 are placed into and press-fit on arbor, fix roller carrier shaft 2, by bottom sealing ring 5, strengthen set 6 and bearing 4 one step is press-fit into place, then load onto jump ring (not shown, use 65MNSpringSteel making) position, afterwards by axle sleeve 8 and be coated with spread the sleeve sealing circle 9 of grease 11, sealing external cover 10 press-fits, and so far completes whole assembling process.
In general, term used in the appended claims is not necessarily to be construed as being limited to present claims the specific embodiment disclosed in specification and claims, and should be interpreted as including all possible embodiment and the four corner of equivalent arrangements that such claims are comprised.
