Description
Technical field
The utility model relates to a kind of wheel, is specifically related to one and is coated with elastomeric transfer wheel, delivery wheel or conveying rubber tire.
Background technique
Current conveying rubber tire mostly on the market is by metal-cored, the bonding elastomeric material of plastic core, and then equips bearing.With jump ring or the direct locked bearing of impact style.In old-fashioned course of working, first need metal-cored or plastic core to carry out rough surface process, and then carry out sulfuration encapsulate, and then the process of effects on surface burr, and then load onto bearing, and then load onto jump ring or by stuck for the protruding position punching press of bearing outer ring and metal or plastics inner ring;
The defect existed in old-fashioned processing: be easily out of shape because metal-cored (non-heat treatment) and plastic core are heated in the process of heating in elastomer course of working, insufficient strength.Elastomeric material can be flowed in deformation position, make product appearance bad, need to carry out No. 2 grinding machine processing.Repeatedly process due to punch press or Presseshydraulic in the process that delivery wheel equips bearing and locked bearing and make to increase product cost reduction up-to-standard rate.And due to the bearing of old-fashioned delivery wheel to be equipped in metal-cored or plastic core together with time, need to consider to coordinate equipment size, bearing is made to have the narrow limitation of model and size (especially at the delivery wheel being less than 80mm external diameter), use too small bearing to make it bear load excessive, working life reduces.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, provides a kind of Novel double bank bearing transfer wheel, and it installs simple, and the life-span is long, and manufacturing efficiency is high, and cost is low.
The utility model solves the technological scheme that its technical problem adopts: a kind of Novel double bank bearing transfer wheel, comprises inner ring, outer ring, rolling element, elastomer, retainer, dust cover and outer end sealing cover; Described inner ring, outer ring, rolling element and retainer composition bearing; Wherein, rolling element is steel ball or roller; Described retainer is two, and dust cover is two, and inner ring is one, and outer ring is one; Described elastomer is bonding with bearing outer ring;
Described inner ring while protrude, formed bump; While fall in, form depressed part, center is provided with through hole or is directly thread, and locking nut is by locked for inner ring fixing, and locking nut head sinks to the depressed part of described inner ring; Inner ring is non rotating together with locking nut;
Described outer ring is bonding with elastomer; Bearing outer ring temperature of inner ring during rotation does not rotate; Outer ring outer surface processes at least one groove;
Described rolling element rolls between inner ring and outer ring; Comprise dual row of rolling bodies, and be distributed in bearing end positions;
Described retainer is group steel ball of two in bearing or roller is spaced equably comes;
Described dust cover is positioned between bearing inner race and outer ring and links closely;
Described outer end sealing cover is positioned over the depressed part position of inner ring, installs with bearing outer ring close-fitting.
Further: described elastomeric outer surface is for circle or have flute profile or plagiodont.
Novel double bank bearing transfer wheel described in the utility model, it has the following advantages:
The utility model has to be installed simple, and bearing load is large, and cylindrical is beated little, and the life-span is long, and production and processing simply, can improving production efficiency, the advantage of beautiful appearance;
The utility model in process of production only need bearing and elastomer just passable by bonding by Vulcanization, the follow-up processing avoided, can reduce costs by improving production efficiency, the process heat process of bearing inner race outer ring, thus improve contact fatigue strength and compressive strength and resistance to corrosion, because inner ring projection makes its subsequent installation settle at one go in customized production bearing process, reducing Component installs simple, because the direct contact resilient body of bearing, its design size scope is strengthened, can increase and reduce outer ring inner ring rolling element size, thus increase physical burden, double rolling element makes product not easily swing, rock, lay particular stress on, minimizing is beated.Quality of product significantly promotes.Outer end sealing cover can cover bearing part, makes overall appearance more beautiful;
Transfer wheel in the past by outer ring and elastomer bonding then installation bearing, locking bearing way due to complex manufacturing, operation is many.Reject rate is high.Single loading ability of bearing load is little, swings large, makes the transfer wheel life-span short.And spacer sleeve to be added in addition in follow-up use, its bearing inner race contact interval is overlapped its interval, and bearing outer ring temperature of inner ring during rotation does not rotate.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of a kind of embodiment of the present utility model;
Fig. 2 is the perspective view of embodiment shown in Fig. 1.
Description of reference numerals:
1-outer end sealing cover, 2-dust cover, 3-elastomer, 4-outer ring, 5-rolling element, 6-retainer, 7-inner ring.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
Fig. 1 and Fig. 2 shows a kind of embodiment of the present utility model, and as shown in the figure, a kind of Novel double bank bearing of the utility model transfer wheel, comprises inner ring 7, outer ring 4, rolling element 5, elastomer 3, retainer 6, dust cover 2 and outer end sealing cover 1; Wherein, rolling element 5 is steel ball or roller, and shown steel ball or roller are according to bearable load number; Described retainer is two, and dust cover is two, and inner ring is one, and outer ring is one; The play that bearing mnanufacture of the present utility model will reduce it makes its minimizing beat;
Concrete:
The outer surface of described elastomer 3 can be circular, has flute profile and plagiodont; It is bonding with bearing outer ring 4;
Described inner ring 7 while protrude, fall in, have through hole, inner ring is non rotating together with internal locking screw, and locking nut head can sink into by the position fallen in, and the inner ring of protrusion contacts and makes it possible to, by its interval, transfer wheel be rotated freely at mounting hole;
Described outer ring 4 and elastomer 3 bonding by Vulcanization, bearing outer ring plays the effect of back-up roller kinetoplast; Bearing outer ring temperature of inner ring during rotation does not rotate, and only plays a supportive role, and outer ring outer surface processes one or more groove, makes bonding more firm;
Described rolling element 5 is the parts bearing load, and it rolls between inner ring and outer ring; Be distributed in bearing end positions by dual row of rolling bodies, the play reducing it in bearing manufacture process makes its minimizing beat, and according to the maximum load-carrying capacity assembling rolling element of bearing, make it have carrying symbol load large, cylindrical is beated little, the advantage of life-span length.
Described retainer 6 is group steel ball of two in bearing or roller is spaced equably comes, and each steel ball or roller are normally rolled running between raceway.
Described dust cover 2 dustproof effect; Be positioned between bearing inner race and outer ring and link closely.
What described outer end sealing cover 1 was positioned over inner ring falls in position, installs with bearing outer ring close-fitting; Outer end sealing cover can carry out LOGO customization according to transfer wheel color shape, plays aesthetic appeal and propaganda function.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
