Abstract
Disclosed is a convenient maintenance large ring cold machine trolley wheel which pertains to the technical field of sintering equipment in the metallurgical industry, and solves the problem of providing a convenient maintenance large ring cold machine trolley wheel which can reduce the manufacturing difficulty and cost, and maintain the seal effect. The utility model adopts the technical scheme that the trolley wheel comprises a wheel, a wheel axle, an end cover, a seal sleeve and a bearing; wherein the axle head of the wheel axle is provided with a fastening pressure plate which is fixed on the end face of the axle head by a fastening bolt; the circumferential part of the pressure plate which is larger than the sectional area of the axle head is pressed against the outer sleeve side of the bearing; and the inner side of the circumference of the seal sleeve is provided with an annular seal groove which is sheathed with a seal felt ring. The axial fixation of the wheel axle adopts one method of pressure plate fixation, so the processing cost is reduced and the amount of maintenance is decreased; the framework oil seal in the prior art is replaced by the felt ring seal, thus avoiding the defects of easy aging, deformation and damage of the framework oil seal in the practical production, as well as inconvenient dismounting, and obtaining remarkable effect with simple improvement.
Description
Technical field
The utility model relates to a kind of large-scale circular cooler trolley wheel, belongs to the agglomerating plant technical field of metallurgy industry.
Background technology
Large-scale circular cooler trolley wheel is one of vitals of circular cooler trolley, in the prior art, wheel hub axially adopts circular nut and pressing plate double fixed mode, the bearing that is sleeved on wheel hub is 352226E, give oil lubrication by the outside, the two seals of labyrinth packing and outside framework oil seal is adopted in sealing.This structure has many unreasonable parts, because spindle nose adopts big nut fastening, must so not only increase manufacture difficulty and cost in the spindle nose cutting thread, and the screw thread place is easy to break during maintenance, and the lighter will repair again, and whole axle all will be scrapped when serious; Again because the material of outside framework oil seal is that rubber is made, aging easily, and outside framework oil seal belongs to easy stressed part in this design, and the easy stress deformation of liner skeleton lost efficacy, have influence on the ordinary production operation of central cooler, increased the consumptive material expense and the maintenance workload of spare part again.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of prior art defective that overcomes, and can reduce the large-scale circular cooler trolley wheel of being convenient to safeguard of manufacture difficulty and cost and maintenance sealing effectiveness.
The technical scheme that solves the problems of the technologies described above is:
A kind of large-scale circular cooler trolley wheel of being convenient to safeguard, it comprises wheel, wheel shaft, end cap, sealing shroud, bearing, bearing installation is in the axis hole of wheel, sealing shroud is installed in the inboard of wheel axis hole centre bearer, and its improvements are that the spindle nose of wheel shaft has clam member, pressing plate is fixed on the spindle nose end face by binding bolt, the pressing plate area is greater than the spindle nose cross section, and its medial surface and spindle nose closed contact are pressed against the overcoat side of bearing greater than the circumferential section of spindle nose sectional area.
The above-mentioned large-scale circular cooler trolley wheel of being convenient to safeguard has annular seal groove in the inside circumference of sealing shroud, and seal groove is embedded with the sealing felt collar.
Adopt the bogie wheels of this structure, the axial restraint of wheel shaft only adopts pressing plate to fix a kind of mode, cuts down finished cost, and has reduced maintenance workload; Outside framework oil seal in original technology is replaced by felt-ring seal, avoided in the actual production that outside framework oil seal is aging easily, distortion, damaged, and the defective of dismounting inconvenience, each part stress of wheel is more reasonable like this, the wheel dismounting is safeguarded convenient, has obtained significant effect with the simplest improvement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: wheel 1, wheel shaft 2, end cap 3, sealing shroud 4, bearing 5, pressing plate 6, bolt 7, sealing felt collar 8
The specific embodiment
Show among the figure that the utility model comprises wheel 1, wheel shaft 2, end cap 3, sealing shroud 4, bearing 5, pressing plate 6, sealing felt collar 8.Compared with prior art, aspect two, technological improvement is arranged.At first be that the double fixed mode of wheel shaft 2 axial restraints of the prior art is changed into single pressing plate fixed form.In the prior art, the area of pressing plate 6 is identical with the sectional area of wheel shaft 2, in improvement, can fix wheel shaft 2 effectively in order to make pressing plate 6, with the enlarged areas of pressing plate 6, make pressing plate 6 excircles and bearing carrier ring closed contact, compress, by binding bolt 7 pressing plate 6 and spindle nose are fixed.Secondly, outside framework oil seal of the prior art is cancelled, and is replaced by sealing felt collar 8, and method is annular seal groove of processing in the circumference of sealing shroud 4, will seal felt collar 8 and embed in the seal groove.This encapsulating method has avoided in the prior art that outside framework oil seal is aging easily, distortion, damage, and the defective of dismounting inconvenience.
In order to make bearing lubrication more smooth and easy, the utility model adopts the 352226EW33 bearing, increases by one lubricating oil groove at this bearing outside middle part, at circumferential uniform 3 fuel feed holes, lubricating oil flows along lubrication groove, enters the bearing roller center from 3 fuel feed holes, makes bearing lubrication more reasonable.
