Definitions
- the invention relates to a sealing ring for sealing a bearing housing, in particular the bearing housing of a pillow block bearing, the sealing ring being insertable into a recess in the bearing housing and with the aid of the sealing ring a seal between the bearing housing and a shaft projecting from the bearing housing can be realized. Furthermore, the invention relates to a pillow block bearing with a sealing ring for sealing the bearing housing, the pillow block bearing being designed to support a shaft, the shaft having a roller and the roller serving to drive and / or guide a conveyor belt.
- sealing rings for sealing bearing housings or sealing rings in plummer block bearings are particularly special
- Conveyor belts are guided or driven with the help of rollers.
- a roller of this type is provided on a shaft, which is in contact with the underside of the conveyor belt, the rotational movement of the shaft being transmitted to the conveyor belt via the roller.
- the elements for supporting the shaft i.e. the pillow block bearings or the bearing housings used, are mostly in
- Such sealing elements are preferably formed in two parts, namely as semi-ring-shaped elastic elements and have, for example, an outer diameter of approximately 100 mm, an inner diameter of approximately 70 mm and a thickness or width of approximately 5 mm.
- sealing lip-like extensions are provided on the inner sides, ie on the inner periphery of the flexibly designed sealing rings, which form a sealing seal on the outer periphery of the shaft in order to prevent dirt particles from penetrating into the bearing housing.
- the outer area of the semi-ring-shaped, flexible sealing elements is received in recesses or grooves in the bearing housing, so that they are fixed relative to the bearing housing, but the shaft can rotate within the inner area of the "sealing ring".
- Household garbage is also often problematic.
- waste parts fall into the space between the conveyor belt and pillow block, in particular elongated elements such as video or audio cassette tapes, which are mostly in household waste and hang down on the side of the conveyor belt, are "rolled up” on the rotating shaft. For this reason, are formed between pillow blocks and
- Conveyor belt “garbage balls” that arise in the area of the shaft between the roller and the pillow block. Due to the rotation of the shaft, the enlargement of the “garbage balls” and under the influence of moisture and other garbage components, forces are generated. Such forces act, in particular in the lateral direction, on the bearing housing or plummer block housing and in particular on the sealing ring of the bearing housing arranged to the side of the conveyor belt. Practice has shown that this in particular damages the sealing rings known in the prior art. The sealing rings break or are pressed into the interior of the bearing housing itself due to the lateral forces. As a result, the interior of the bearing housing becomes dirty, the bearing elements are damaged and such bearing elements often have to be replaced.
- the invention is therefore based on the object to design and develop a sealing ring of the type mentioned or a pillow block with a sealing ring of the type mentioned in such a way that in particular the penetration of dirt particles into the interior of the bearing housing is largely avoided, vzw. the risk of damage to the bearing elements and the necessary maintenance and the associated costs are reduced.
- the sealing ring is made of an essentially inflexible material.
- the sealing ring is arranged on the side of the bearing housing facing the conveyor belt and is made of an essentially inflexible material.
- the invention is based on the basic idea of producing the sealing ring from a flexible material, ie not from rubber or an elastomer, rather than from the prior art, but from an inflexible material, preferably steel or a steel alloy.
- This has the advantage that such sealing rings made of inflexible material can better withstand the lateral attack forces, i.e. these do not break so easily or are not damaged so easily that they cannot be pressed into the interior of the bearing housing. Consequently, the sealing ring according to the invention or for the pillow block bearing according to the invention always ensures optimal sealing of the bearing housing, so that the disadvantages described at the outset are thereby avoided and large costs can be saved.
- 1 is a pillow block, with a mounted shaft in a schematic representation from the side,
- FIG. 3 shows a sealing ring in a simple schematic representation from the front
- Fig. 4 is a conveyor belt, driven by a roller and a shaft, the shaft being supported by the pillow block shown in Fig. 1, in a simplified schematic, partially sectioned view from the side.
- FIGS. 1 to 4 show at least partially a sealing ring 1 for sealing a bearing housing 2, in particular a bearing housing 2 of a pillow block bearing.
- the bearing housing 2 shown in FIGS. 1 to 4 is designed here as a bearing housing 2 of a pillow block bearing and has an upper housing part 2a and a lower housing part 2b.
- the sealing ring 1 is now in an unspecified
- Recess of the bearing housing 2 can be used, a seal between the bearing housing 2 and a shaft 3 protruding from the bearing housing 2 being able to be realized with the aid of the sealing ring 1. With the help of the sealing ring 1, the interior 2c of the pillow block bearing is thus sealed from the surroundings.
- FIG. 4 shows the pillow block, which is used here to support the shaft 3, the shaft 3 here having a roller 4.
- the roller 4 serves to drive and / or to guide a conveyor belt 5 on which household waste 6 or the like is transported.
- the sealing ring 1 is made of an essentially inflexible material.
- the sealing ring 1 can now better absorb the laterally occurring forces and is therefore no longer pressed into the interior 2c of the bearing housing 2.
- an optimal sealing of the interior 2c of the bearing housing 2 is ensured, as a result of which damage to the bearing elements 7 is avoided and also the maintenance effort and the associated costs are significantly reduced.
- the sealing ring 1 is preferably made of steel. It is also important, however, that the material of the sealing ring 1 is softer than the material of the shaft 3. For example, the sealing ring 1 could be made of ST-50 steel and the shaft 3 of ST-70 steel.
- the sealing ring 1 is now dimensioned such that, of course, a blockage of the rotation of the shaft 3 is avoided, ie the shaft 3 can rotate freely, but nevertheless an optimal sealing of the interior 2c of the bearing housing 2 is ensured. This is possible by appropriate fits and dimensions of the sealing ring 1. Vzw. there is a clearance fit with a clearance between shaft 3 and sealing ring 1 of max. Max. 0.2 to 0.3 mm realized.
- a lubrication is preferably implemented between the inner edge of the sealing ring 1 and the shaft 3 via provided, but not shown, lubricating nipples.
- the sealing ring 1 shown here in FIGS. 1 to 4, at least partially, is shown here for a pillow block bearing, but it is conceivable that such sealing rings 1 can also be used for other bearing types, that is, they are not only used for pillow block bearings. However, it is also conceivable that the one-piece sealing ring 1 is made in two parts, that is, two semi-ring-shaped elements form an entire sealing ring 1. Also the size, i.e. the dimensioning of the sealing ring 1 is very different depending on the bearing type and bearing size used.
- the bearing housing 2 is designed so that it has a recess for the sealing ring 1, in particular an annular groove. This can be seen here from FIG. 2.
- FIG. 2 shows that the sealing ring 1 is at least partially inserted into the recess of the bearing housing 2, which is not described in more detail here, namely the outer circumference of the sealing ring 1 is inserted into the corresponding recess or groove. In this way, the lateral support forces for the sealing ring 1 are also realized.
