Abstract
The utility model discloses a self-cooling carrying roller which comprises a cylinder body, a carrying roller shaft which is arranged inside the cylinder body, two bearings which are arranged at the two ends of the carrying roller shaft, corresponding bearing bases and two end caps. The self-cooling carrying roller is characterized in that the self-cooling carrying roller further comprises two fan blades which are respectively arranged on the shaft bodies on the inner side of the two bearings at the two ends of the carrying roller shaft. The self-cooling carrying roller not only solves the sealing problem of a traditional carrying roller, but also solves the cooling problem of the carrying roller, so that using the carrying roller can achieve the effects of high efficiency and the long service life.
Description
Technical field
The utility model relates to transhipment load transfer device, particularly from cooling carrying roller.
Background technology
In the industrial and mining enterprises such as metallurgy, cement, coal, power plant, chemical industry, belt feeder is widely used in the transhipment of bulk material and carries, carrying roller is widely applied as belt conveyer parts, play the effect of carrying adhesive tape and material, therefore carrying roller is also the parts that the amount of breaking down is the highest, it is distributed in the whole process of complete machine, has determined the result of use of belt conveyer.Under normal circumstances, between carrying roller and adhesive tape, be friction of rolling, the wearing and tearing of carrying roller should be very little.But when carrying roller centre bearer is due to insufficient lubrication, cooling performance is poor, rotational resistance is increased, belt and carrying roller are with regard to accelerated wear test.Taking DTIIGP3304 carrying roller as example, belt feeder belt speed 2M/S, can show that carrying roller uses medium speed to reach 240 revs/min, and the carrying roller using in industry at present does not all have refrigerating function, and carrying roller service life is the 3-6 month conventionally." early failure " of carrying roller mostly by bearing damage too early, stuck or can not cause by flexible rotating, can say that bearing is carrying roller normal operation " heart ".
A large amount of 204, the 205 serial deep groove ball bearings that use of early stage belt conveyer, research think a large amount of bearing damage be due to Selection of Bearings unreasonable due to.Carrying roller uses the large special deep groove ball bearing of play of the series such as 204KA, 205KA gradually at present, but the situation that bearing damage lost efficacy still appears in carrying roller in a large number.Carrying roller applying working condition belongs to low speed underloading, bearing service life >=100000h in theory, but the bearing service life≤20000h of domestic traditional carrying roller, under the serious working condition of dust, bearing life even≤5000h.Analyze by the traditional carrying roller being broken down in scene, find that it is due to bearing defective that a large amount of carrying rollers damage, and bearing damage is because insufficient lubrication causes.
Summary of the invention
The purpose of this utility model is that design, from cooling carrying roller, had both solved the sealing problem of traditional carrying roller, can solve again the cooling problem of carrying roller, allows carrying roller use and really reaches efficient, long-lived.
For achieving the above object, the technical solution of the utility model is:
From cooling carrying roller, comprise, cylindrical shell, the roller carrier shaft in it, the two bearings of being located at roller carrier shaft two ends and corresponding bearing seat and two end cap are set, it is characterized in that, also comprise that two fan blades are arranged at respectively on the axle body of described roller carrier shaft bearings at both ends inner side.
Further, the utility model also comprises, two quiet ceramic ring seats are sheathed on respectively on the roller carrier shaft of diaxon bearing neck bearing inner side, and quiet ceramic ring seat one side is established step, opposite side bottom and bearing against; Two quiet ceramic rings, are sheathed on respectively on two quiet ceramic ring seat stand rank, and quiet ceramic ring end face is connected with quiet ceramic ring seat by bolt; Two moving ceramic rings, are sheathed on respectively on the roller carrier shaft in diaxon bearing, a side and quiet ceramic ring against; Two moving ceramic ring seats, be sheathed on respectively on the roller carrier shaft in diaxon bearing, moving ceramic ring seat one side ring is established step, with this and moving ceramic ring against, and connect through moving ceramic ring end face and moving ceramic ring seat by a straight pin, and the sheathed spring of straight pin leading portion, straight pin front end is against described rubbing surface of end cover; Described rubbing surface of end cover establishes one for the moving fixing annular groove of ceramic ring seat front end along centre hole.
Again, described fan blade two ends adopt two shaft block rings to be fixed on roller carrier shaft.
Have again, described quiet ceramic ring seat or/and moving ceramic ring seat or/and bearing seat or/and end cap or/and fan blade adopts nylon material.
In addition, bearing seat described in the utility model and cylindrical shell are fixed with bolts.
Described rubbing surface of end cover is provided with the limited impression being embedded for described straight pin front end.
The utility model adopts high-hardness ceramic as contact-type seal material, is made up of quiet, the movable friction plate of side seal friction pair dynamic and static ceramic ring, at bearing seat inside line, one fan blade is installed, and fan blade is fixed on roller carrier shaft, keeps 5mm spacing with bearing seat.
Be installed on support roller frame for belt conveyor from cooling carrying roller, two ends fixed card is in draw-in groove, when adhesive tape moving linearly, because driving carrying roller cylinder, friction force effect circles centered by roller carrier shaft, suppose: belt feeder belt speed 2M/S, carrying roller rotating speed can reach 240 revs/min, from the principle of relative motion, with the rotating speed of 240 revs/min, bearing is carried out to cooling down like fan blade in using always, the heat that bearing operation produces can be discharged carrying roller cavity in time, ensure lubricant effect, extend the service life of bearing, thereby also extend the service life of carrying roller.
The beneficial effects of the utility model are:
The utility model can be used in any belt transporter from cooling carrying roller, due to automatically cooling, greatly improve carrying roller service life, especially under the serious environment of dust, fan blade is being discharged heat simultaneously, and the air-flow of formation produces small malleation to two end axles bearing, makes dust be difficult for gathering at bearing seat end face, greatly improve carrying roller environment for use, ensured the service life of carrying roller maximum.
