Definitions
- the invention relates to the novel construction of traction sheaves for wire rope drives and the like. In particular in the elevator sector, whereby an improved power transmission is to be made possible.
- Access devices operated with wire rope for standing rope constructions (suspension bridges, rope-tensioned hall roofs, cable cranes, cable cars), • selected cable car drives,
- a further field of application of the invention are mechanical continuous conveyors, which operate according to the “frictional connection” drive principle and meet the requirements of magnetic materials.
- the groove of the traction sheave which receives the load element consists of segment pieces which are designed as pole pieces of a series of electromagnets with alternating polarity, the flow of force of which is guided from one pole to the adjacent through the load element ,
- a traction sheave in particular for use in mining, is known in which a lining which is freely movable on the rim circumference in the form of a flexible elastic ring with lining elements attached to it is introduced into the grooves of the rim.
- DE 36 26 045 A1 also describes a traction sheave for mining, in which a freely movable coating is arranged along the circular line of the groove of the ring.
- This covering consists of two layers, namely the upper layer made of an elastic strip of material and the layer lying directly on the rim and divided into sections, which are rigidly connected to one another.
- the sections mentioned here consist of a (sliding) bearing material.
- DE 39 23 192 A1 relates to a traction sheave, in particular for
- Patent specification DE 1.202.587 B describes a reinforcement for use for rope and traction sheaves in mining, in which lining materials made of light metal, hard plastic and the like are attached to the base body of the traction sheave and at the same time the friction coefficient and the wear resistance of the lining are increased.
- the patent specification DE 1.120.702 B describes a special lining material for traction sheaves for mine shaft mining, which consists of a special cast alloy G AI Si. These lining blocks are installed alternately with lining blocks made of thermoplastic or thermoplastic-like plastics on the circumference of the traction sheave.
- the use of force line fields to increase the driving ability is known from mining and mooring winches for single-rope operation.
- the solutions are structurally complex, require a large amount of space and make the system technology more expensive
- the object of the invention is therefore to significantly increase the transmission forces from elevator traction sheaves to the rope to be driven, in particular under extreme stress conditions, such as are present in high rope force ratios and / or small traction sheave to rope diameter ratios.
- the object of the invention includes analog improvements to increase the transmission forces in the pairings of drive drum / steel conveyor belt and drive drum / chain, each with a simplified design of the other system components.
- inlays in the form of high-energy magnets from the group of rare earths with energy products of, for example, 385 kJ / m 3 are introduced along the circumferential line of the groove (s) present in the traction sheave ring, which are inserted into adapted recesses in the groove track are recessed to conform to the surface.
- This arrangement can be made for several grooves lying side by side. Complementary respectively between the inlay's ring segments are arranged.
- Classic traction sheave materials such as GG and the like can be used as material for the above traction sheave ring or the ring segments or new construction materials such as steel foam materials and fiber composite ceramics which increase the friction value and meet the requirements for pressure resistance and wear resistance for use in elevator traction sheaves or similar applications. If wreath segments are selected, steel foam materials and / or fiber composite ceramics should preferably be used. This special procedure makes it possible to increase Coulomb's frictional force, since the coefficient of friction of the rest reaches values of 0.4 when using, for example, fiber composite ceramics, and additionally the normal force from the rope forces of by the high-energy magnets inserted as inlays at regular intervals a normal force generated by the magnetic forces is superimposed. The following applies to this statement:
- Fu M gn tangential resistance force acting on the circumference of the traction sheave in the magnetic area against the rope elongation or slip caused by the greater rope force;
- F gn magnetic adhesive force;
- ⁇ Mgr > coefficient of friction in the magnetic range.
- High-energy magnets which are to be manufactured as permanent magnets based on adhesive forces, hardness, shape, wear resistance, adapted to the application. They are arranged in the respective groove track in such a way that the axis of the magnet and thus the magnetic force is aligned radially.
- the inlay segments and possibly additional ring segments are arranged distributed over the 360 ° circumferential line of the traction sheave ring, these segments being evenly spaced by the circumferential angle ⁇ .
- the size of the angle ⁇ depends on the desired driving ability of the drive pulley-rope or drive pulley-belt pairing.
- This technical approach makes it possible to equip round grooves with at least coefficients of friction that of wedge grooves with a defined wedge angle and achievable wear condition, but in contrast to the V-groove or the undercut round groove, guarantee a greatly reduced groove wear (low pressure) and a long rope service life in relation to the respective design.
- F1 rope forces
- ⁇ (p) deceleration factor
- e basis of natural logarithms
- ⁇ apparent coefficient of friction
- ß geometric wrap.
- FIG. 1 shows the design of the traction sheave ring with ring segments made of fiber composite ceramic, arranged between the inlays made of high-energy magnets
- FIG. 2 shows a groove segment which consists of a material that differs from the other version of the groove ring.
- the entire ring could also be made of this material, into which the holes for receiving the high-energy magnets could then be made.
- Fig. 3 The design of a traction sheave for high-performance friction pairings, in which in the groove tracks of the traction sheave ring as inlay segments
- FIG. 1 An exemplary arrangement of ring segments 5 and possibly inlay's 6 over the 360 ° circumferential line of the traction sheave ring 2 is shown in FIG. 1.
- the ring segments 5 are in each groove track 3, see. Section A-A, spaced apart from each other over the circumferential angle ⁇ .
- they can consist of one piece in the axial direction, into which all groove tracks 3 are introduced.
- inlay segments 6 high-energy magnets
- inlay segments 6 high-energy magnets
- the exemplary geometry of a wreath segment 5 shows as detail B FIG.
- the shape of the groove 3 is determined by its radius of curvature, where d is the
- Diameter of the rope 4 corresponds.
- the length I of a wreath segment 5 is at least 3 times the rope diameter d, i.e. I ⁇ 3d.
- FIG. 3 illustrates the design of a traction sheave for high-performance friction pairings with high-energy magnets 6 introduced as inlay segments, analogously to the structure according to FIG. 1.
- the high-energy magnets 6 have a cylindrical shape, see. Detail C, with the following dimensions for height h and diameter of the magnets d M : h ⁇ 25 - 35 mm d M ⁇ 20 - 32 mm.
- the polarity is also shown here.
- a traditional gray cast iron (GG) material is used as the material for the traction sheave base body 1 and traction sheave ring 2.
- the wreath can be manufactured separately and connected to the base body in a suitable form.
