Abstract
The invention provides a high-sealing oil injection type small bearing roller of a feeder. The small bearing roller structurally comprises a roller body, bearing chambers formed in the two sides of the roller body, and a center shaft penetrating through the two bearing chambers and the roller body. Bearings are installed between the bearing chambers and the center shaft respectively, the inner rings of the bearings make contact with the outer wall of the center shaft, and the outer rings of the bearings make contact with the inner walls of the bearing chambers. Ring-shaped sealing covers sealing the interior of the roller body are arranged on the outer sides of the bearing chambers, the inner rings of the sealing covers are closely attached to the center shaft, and the outer sides of the sealing covers are fixed to the bearing chambers through bolts. Bolt fixing grooves containing the bolts are formed in the bearing chambers and used in cooperation with the sealing covers, and lubrication holes communicated with the bearings are formed in the bolt fixing grooves. Compared with the prior art, coal dust can be effectively stopped from entering the bearings and lubricating oil can be effectively prevented from seeping in the use process, the lubricating oil can be conveniently injected in the maintenance process, the service life of the small bearing roller is prolonged, the maintenance workload is small, and the practicality is high.
Description
Technical field
The present invention relates to industrial conveying feeder field of components, a kind of simple in structure, practical feeder high sealing can oil-filling type load-bearing doffer specifically.
Background technology
In national economy production process, relate to bulk, granular, during the transportation of granular material, the severe of loose dust and working environment because material overflows in transportation, Chang Yinwei material, dust immerses load-bearing doffer bearing chamber, cause bearing damage, old being designed to adds felt collar or outside framework oil seal on end cap, structure relative complex, simultaneously because mechanical drive is in the process of long-time running, felt collar or skeleton there will be comparatively serious wearing and tearing and components aging, time one, long its sealing effectiveness was bad, effectively blocks dust immerses bearing chamber, and can not safeguard by charging-up lubricant oil, bearing damage can not be used load-bearing doffer, the replacing time is long, maintenance capacity is large, cost is high, do not tackle the problem at its root yet.Based on this, now provide a kind of feeder high sealing addressing the above problem can oil-filling type load-bearing doffer.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, provides a kind of and maintains easily, feeder high sealing can oil-filling type load-bearing doffer.
Technical scheme of the present invention realizes in the following manner, this a kind of feeder high sealing can oil-filling type load-bearing doffer, its structure comprises cylinder, be arranged on the bearing chamber of cylinder both sides, the center shaft that runs through two bearings chamber and cylinder, bearing is all installed between each bearing chamber and center shaft, this bearing inner ring contacts with center shaft outer wall, outer ring contacts with bearing chamber inwall, described bearing chamber arranged outside has the seal cover cap of cylinder inner sealing, sealing is covered in the form of a ring and its inner ring is closely attached on center shaft, outside is bolted on bearing chamber, be used in conjunction with sealing lid, on bearing chamber, offer the bolt hold down groove of placing bolt, in this bolt hold down groove, offer the lubrication hole that is communicated with bearing.
Adopt said structure, doffer inside, by the effect of seal cover cap, coordinates center shaft and cylinder to form hermetically-sealed construction, thereby effective sealing bearing chamber, blocks dust immerses this bearing chamber, and simultaneously sealing is covered position after sealing and fixed, and can not occur easily loosening situation; Separately in bolt hold down groove, offer lubrication hole, while making to lubricate, only lubricating oil need be poured in bolt hold down groove, lubricating oil just can enter by lubrication hole the lubricating effect of the complete matched bearings of bearing chamber, because integral body is sealing shape, can effectively suppress oozing out of lubricating oil like this.
As preferably, the inner ring of described seal cover cap is lip packing and this inner ring and center shaft outer wall and flexibly connects.By the hermetically-sealed construction of this technical scheme, make seal cover cap can not realize self sealss when being bolted, rely on operation pressure effect to make lip compress the outer wall coupling surface of center shaft, auto-compensation abrasion loss, its sealing load can pass through the fastening realization of bolt, and actv. has guaranteed the sealing function of seal cover cap.
Further, Y-shaped, the V-arrangement of the lip packing part of described seal cover cap inner ring, U-shaped, flower bud shape, J-shaped or L shaped.The lip seal of said structure can be along with the continuous increase of operation pressure, and contact distribution form changes according to its shape, and it is tightr that lip coordinates with center shaft outer wall, and sealing property is better.
As preferably, described bolt hold down groove is parallel to center shaft setting, and lubrication hole is through this bolt hold down groove and be skewed setting.The setting of the lubrication hole by this structure, can effectively avoid the situation that lubricating oil overflows lubrication hole to occur, and lubricant effect is desirable.
Further, described lubrication hole contacts with inner wall of rotary drum perpendicular to the setting of bolt hold down groove and its outer end.The lubrication hole of this structure is easy to processing and fabricating, in use, can play the effect of even lubricating bearings simultaneously, due to its vertical relation, lubricating oil can substantially all be used up, and can not cause waste, reduces old loss, practical.
As preferably, the both ends symmetry that described center shaft stretches out bearing chamber offers the draw-in groove of indent, bearing support is fixed in the draw-in groove of these center shaft both sides, and the center shaft after fixing is relative with bearing support static, and the top of this bearing support is mutually concordant with the top of center shaft.By the setting of this bearing support, center shaft can not rotated when drum movement, guaranteed that cylinder rolls normally.Described draw-in groove is by groove milling mode processing and fabricating, bearing support can adopt common structure, such as its structure is arranged to the form that two bearing plates are joined a base plate, two bearing plates are used for placing vertical fixing bearing plate of draw-in groove, base plate, if need to its function be expanded when reality is used, such as realizing its portable function, in base plate bottom, install cardan wheel additional.
Further, on each bearing chamber, evenly offer at least four bolt hold down grooves, describedly evenly refer to that the straight-line distance between all bolt hold down groove circular array and every two adjacent bolt hold down grooves is identical, corresponding, lubrication hole is evenly provided with at least four.
The setting of the bolt hold down groove of this structure can guarantee no matter how cylinder rotates, and must have place's bolt to expose, and so just makes cylinder can turn at any time oiling and safeguards, design hommization more, maintenance process is convenient.
The beneficial effect that the present invention compared with prior art produced is:
A kind of feeder high sealing of the present invention can effectively stop that coal dust immerses bearing, inhibition lubricating oil oozes out in the use procedure of oil-filling type load-bearing doffer, and can facilitate charging-up lubricant oil while safeguarding, increased the service life of load-bearing doffer, a little repair, productive costs is low, structure due to seal cover cap inner ring, make longer its leak tightness of work-hours more fastening, sealing effectiveness is better, practical, there is good economic and social benefit, be easy to promote.
