Definitions

  • the invention relates to a support roller for roller tables or conveyor belts consisting of a tubular body with a cylindrical jacket, at the ends of which are arranged coaxial steering knuckles for receiving support bearings, in which the support roller is rotatably supported.
  • Carrier rollers are used to transport goods. They are in roller tables and
  • Conveyor belt systems used. Depending on the weight and / or the support length of the goods to be conveyed, the distance between the individual idlers is determined. As a result, a large number of identical support rollers is often necessary for longer transport routes. For the transport of piece goods, at least some of these idlers are to be provided with a drive, both individual drives and group drives are known. Single drives are used on roller tables for high piece weights; otherwise group drives with toothing or drive rack are used. A drive can also be dispensed with entirely for slopes with a gradient. Carrier rollers are also used for conveyor belts made of elastic material, in particular for transporting bulk goods.
  • the known idlers consist of a tubular body with a cylindrical jacket, which is made of a seamless or welded tube or from centrifugal casting. At the ends of this tubular body are formed from a round material stub axle, which is usually by means of webs or the
  • Fitted disks are attached to the inner circumference of the tube body, the latter being inserted into the tube ends and receiving the respective steering knuckle concentrically with the tube.
  • the construction of the known idlers requires a variety of steps such as pre-turning, welding and finishing. Sufficient precision is required to ensure the concentricity of the idler roller in the roller table or to ensure in the conveyor belt. Overall, compared to the material value, there is a very high processing price, which makes the known idlers very expensive. If one takes into account that a large number of these identical support rollers are used in roller tables or in conveyor belts, the overall result is a very high cost which makes the entire system more expensive.
  • the object of the present invention is to provide a support roller for use in roller tables or conveyor belts, which can be manufactured much more economically than previously by saving processing steps and which can be economically equipped with roller tables and conveyor belts.
  • the steering knuckles for receiving the support bearing be formed by tapering the two ends of the tubular body therefrom.
  • the new design of the idlers ideally starts with a piece of pipe as the base body, which is produced, for example, in a cold drawing process.
  • the ends of this pipe section are tapered in their diameter so that they form a bearing seat for the support bearings which is directly molded onto the pipe body.
  • the deformation process can take place both in the warm and in the cold state. This advantageously results in an accumulation of material in the region of the bearing point, which is produced according to the invention by reducing the ends of the tubular body by means of pressure rolls or by forging in the die.
  • the seat for the support bearing for example by turning, can be produced by machining in the manner according to the invention, and a connection for driving a driven support roller can also be made in the area of material accumulation in the tapered tube end region.
  • the bearing seat should be produced during machining of the deformed ends of the tubular body by receiving the roller body in steadies; In this way, the requirements for the roundness of the idler roller can be easily met.
  • the proposed idler roller is significantly cheaper to manufacture than the known idler rollers composed of several parts in terms of its manufacturing steps. By using precise raw material, a significant cost saving can be achieved with the same strength of the roll. In addition, weight savings can be achieved by using less material; the tubular body used also offers advantages for roller cooling when transporting warm material. The relatively simple production by rotating machining to deform the pipe ends serves to avoid errors in the conventional complex production principle.
  • the support roller according to the invention is shown in longitudinal section in the left half of the illustration.
  • a conventional idler design is shown, which is compared with the invention below.
  • the wall of a tubular body 1 is designated, which forms the jacket of the support roller.
  • a steering knuckle 4 is inserted into the inner circumference of the tubular body 1, which in turn is in annular disks
  • the end 2a of the tube body 1 is tapered in the manner shown, ie the tube inside and outside diameters are reduced with a conical transition to the tube end towards a pin which forms the steering knuckle for the support roller.
  • This steering knuckle can be produced, for example, by hot forming in the die or by means of spinning rolls, with wall thickening in area 7.
  • a bearing seat 8 is produced by machining, onto which the support bearing is pushed becomes.

Abstract

Rouleau porteur pour trains de rouleaux ou bandes transporteuses, qui est constitué d'un tube à corps cylindrique aux extrémités duquel sont placées, sur les faces terminales avant, des tourillons coaxiaux destinés à être reçus dans des paliers d'appui dans lesquels le rouleau porteur est monté rotatif. Selon la présente invention, les tourillons (4) sont formés à partir du tube (1), par rétrécissement des deux extrémités dudit tube.
