ff conveyor belt roller or

The present invention relates to a novel conveyor belt roll, and in particular to its design and configuration Sealing of the bearing shell.

'! conveyor belt rollers equipped with roller bearings are special in the rough mining operations and with the prevailing there - ^ gefatrren - exposed - is therefore not more or "less" There have been no successful attempts to train and encapsulate the bearings of! Lubricant supply incorporated in the manufacturer's works - if possible keep for a long time, but on the other hand are protected as completely as possible against the ingress of dirt ".

For this purpose there are already mostly fixed between Bright and express seals arranged around the bearing shell been. But it has been shown that these are general used felt seals in the course of time as a result of resinification of the oil or other lubricant become hard, lose their sealing properties and finally a large one Friction with all the resulting disadvantageous poles between Bearing shell unc. ^ call for a hurry.

Other attempts, if possible, between the moving parts In practice, due to the incompressibility of a liquid, it is necessary to apply a completely liquid-impermeable seal or pasty !! Schmi'ermittels failed, so that at all conveyor belt rollers previously on the aera market or accepted the rapid consumption of the summer fee will. what at certain time intervals a control of the bearings and a replenishment of the lubricant supply is necessary, makes »

Apart from the fact that experience has shown that in those with I-conveyor belts and similar conveying devices working rough companies despite the most careful precautions and monitoring these subsequent There is almost no lubrication_, which is why the Storage can sometimes run dry quickly and become unusable the not insignificant danger that either by unsuitable Lubricant or composed by inrolge of carelessness -S particles brought into the interior of the bearing with the lubricant cause damage to the bearing.

Of course, with this factory overhaul of the conveyor belt rollers, any worn or damaged parts are replaced by new ones, so that the user always has flawlessly working conveyor belt rollers , which he no longer needs to worry about at all.

In accordance with the guideline, the special, The tolerances caused by the structure of the Pöraerband rolls are the .Seals attached between the parts moving relative to one another preferably with by capillary gaps of certain !

The outer washer of the bearing shell, which - likewise how this itself is produced by embossing and / or deep drawing from a deep-drawn sheet or the like, is preferably made by means of a delta-shaped triangular spring clamped within the bearing shell in such a way that it is also larger in the radial direction to absorb compressive forces exerted on the cap be able to.

According to the invention, the ends facing one another are used the inserted triangular spring pushed a tube, the middle part located between the ends of the peder through a Marking effecting sealing pliers ocu like.

between the disks 9 and 10 forming the labyrinth seal a larger one due to the accuracy in the axial direction Should be wide as shown in the drawing.

In a very similar way, the high precision possible in the radial direction is achieved in the case of the interior of the conveyor belt roller Sealing of the bearing exploited; where as a result of the all-round Closure of the roll iniienraumes towards about from the outside penetrating smack a sufficient additional sewage it is given that with the temperature fluctuations approximately occurring fluctuations of the lubricant no dirt is brought into the bearing -

This inside seal of aes bearing consists in principle of a sheet metal ring It of an essentially U-shaped profile. The inner planesehiJaci of the sheet metal ring 11 sits in a frictional and liquid-tight manner on the stationary shaft 12, on the shoulder IJ of which the inner race 14 of the ball bearing is supported. The cylindrical outer surface of the outer surface of the ring 11 is by turning and / or grinding with a high precision to such a degree that between two small pieces of the work piece and / or the precisely cylindrical inner wall that is turned off and / or ground off with high precision of the cylindrical ring-shaped part 7 of the bearing shell a slot of the order of magnitude of 0.01 mm remains., .which a sufficient, based on capillary action sealing of the lubricant content of the bearing in the sense "is" that any temperature increase due to the opalt between ^ the inner wall of the zyllnderringföriülgen bearing shell part 7 and the outer wall of the Aussenflansch.es of the sheet metal ring 11 penetrating quantities of lubricant In the space 15 between the inner wall of the part 5 tuiä oe * ¹ wave-shaped side of a ring 11 facing this part 5, quantities of lubricant can flow back into the interior without any contraction due to a cooling down, without the lubricant causing any damage has suffered.

Even if, as a result of the dimensional inaccuracies in the radial sighting, the width of the space T5 is of the order of magnitude Ton should fluctuate tenths of a millimeter or more, so in no way does the width of the aylina shell shape Capillary gap on the outside of the outer flange aes Hinges 11, which is solely for keeping the lubricant supply is responsible within the bearing shell, changed, especially not enlarged.

The desired exact fit in the axial direction of the parts pushed into the cylinder jacket 4 of the bearing housing, namely the races of the ball bearing δ / 14 and the grooved disks 9/10 of the labyrinth seal, is achieved in a way that prevents the labyrinth seal parts from being pressed together at the front caused by the approximately L-shaped cross-section having the closing disk Io, which with its curved outer edge rests on the inner wall of the cylinder jacket 4 for liquid purposes and at the same time on the.

The end cover 16 is held in a manner that also absorbs axial thrusts by the delta-shaped each 18, which has an approximately rectangular cross-section with its corners in the deep, for example, by stamping and upsetting - ^ inner ring groove 19 between the outer shield 3 ¹¹²¹ C-cylinder jacket part 4 of the bearing shell is used resiliently. A small tube 20 is pushed over its free ends, the middle part 21 of which between the ends of the 5 ″ of the 18 remaining part 21 is pressed together by means of sealing pliers or the like so that removal of the 1 ″ ″ 18 without damaging a seal serving as a seal is pressed together and the embossed middle part of k1 aes tube 20 is not possible.
