Definitions

  • the present invention lies in the mechanical arts and relates, in general, to cableway or ropeway systems. More specifically, the invention pertains to a running roller for the traveling-gear mechanism of the transport assembly of a cableway system, having a disk-type roller body.
  • a running roller for the traveling-gear mechanism of a transport assembly of a cableway system comprising:
  • the objects of the invention are satisfied in that the roller body which is produced from metal, in particular from steel, is provided along the circumference of the roller body with a running surface that encloses the roller body and is produced from a plastic material.
  • the roller body Since the roller body is produced from a metal, the risk of the running roller rupturing is reduced to a permissible extent. Since, in addition, the roller body is provided with a running surface produced from plastic material, the running noise of the running roller is reduced to the sought-after extent. Since, in addition, it is only the running surface which is produced from a plastic material, the roller body, which is produced from metal, assumes the function of the running roller in the case of the running surface rupturing, this achieving the emergency running properties which are necessary during the coupling operation of the clamps. Such a running roller thus completely avoids the disadvantages of the known prior art.
  • the roller body is formed, on its outer periphery, with at least one annular protrusion of which the outer diameter is at least 80%, in particular 90% to 95%, of the outer diameter of the running roller, and, in addition, the outer side surfaces of the at least one ring-like protrusion are spaced apart from one another by a distance which is at least 65%, in particular 75%, of the distance between the lateral guide surfaces of the running roller.
  • the roller body is preferably also designed, along the circumference, with through-passages, in particular with bores, which have the plastic material which forms the running surface passing through them. This achieves optimum fastening of the running surfaces, which are produced from a plastic material, on the metallic roller body.
  • the roller body in the region of its hub, extends over the entire thickness of the running roller, whereas, radially outside its hub, it has a thickness which takes up approximately 70% of the thickness of the running roller.
  • roller body is designed with a single ring-like protrusion of which the outer diameter is approximately 90% of the outer diameter of the running roller and of which the width is approximately 85% of the distance between the lateral guide surfaces of the running roller.
  • the roller body prefferably be designed, on its circumference, with two ring-like protrusions of which the outer diameter is approximately 90% of the outer diameter of the running roller, and of which the outer wall surfaces are spaced apart from one another by a distance of approximately 85% of the distance between the lateral guide surfaces of the running roller.
  • the roller body may be designed with a cross-sectionally approximately T-shaped protrusion, the crossbar thereof being located in the region of the outer circumference. It is also possible for the roller body to be designed with a protrusion which runs in wave form over the circumference of the running roller.
  • FIG. 1 shows a cableway cabin with a running-gear mechanism, a clamping device and a suspension bar, viewed in a direction parallel to the haulage cable;
  • FIG. 2 is a partial view of the running-gear mechanism and the clamping device on a larger scale than FIG. 1;
  • FIG. 3 is an axial section taken through a running roller mounted on the running-gear mechanism
  • FIG. 4 is an axial section taken along a diameter through the running roller of FIG. 3;
  • FIG. 4 a is a section taken along the line A-A in FIG. 4;
  • FIG. 5 is an axial section taken along a diameter through a further embodiment of the running roller according to the invention.
  • FIG. 5 a is a section taken along the line B-B in FIG. 5;
  • FIG. 6 is an axial section taken along a diameter through a further embodiment of the running roller according to the invention.
  • FIG. 6 a is a section taken along the line C-C in FIG. 6;
  • FIG. 7 is an axial section taken along a diameter through a further embodiment of the running roller according to the invention.
  • FIG. 7 a is a section taken along the line C-C in FIG. 7;
  • FIG. 7 b is a diagrammatic plan view onto the periphery of the running roller and viewed in a radial direction.
  • FIGS. 1 and 2 there is shown a cableway cabin or gondola 1 which can be coupled to a haulage cable via a suspension bar 2 .
  • a clamping device 3 Located at the top end of the suspension bar 2 is a clamping device 3 and a running-gear mechanism 4 with at least two running rollers.
  • FIG. 2 illustrates, on an enlarged scale, a portion of the suspension bar 2 , the clamping device 3 , the running-gear mechanism 4 with the running rollers 5 , a conveying rail 11 , the haulage cable 12 , and a friction surface 13 , on which the conveying rollers act in the stations.
  • the running-gear mechanism 4 is designed with at least two bearing bolts 41 , on which a running roller 5 is mounted by means of a ball bearing 42 .
  • the end surface of the bearing bolt 41 is designed as a securing cover 43 by means of which a securing ring 44 is retained.
  • the securing ring engages axially over the ball bearing 42 , as a result of which the latter is secured axially in position.
  • the guide rail 11 in which the running rollers 5 are guided, is also illustrated.
  • the running rollers 5 comprise a roller body 51 , which is produced from a metal, in particular from steel, and a running ring 61 , which is produced from a plastic material, in particular from polyamide.
  • the running ring 61 ensures the sought-after guidance of the running rollers 5 in the guide rail 11 with a low level of noise.
  • the top part of the drawing illustrates a complete running roller 5 , which is designed with the running ring 61 on its outer circumference.
  • the bottom part of the drawing illustrates the running roller 5 in the case of which the running ring 61 has broken off.
  • the novel configuration with now be explained with reference to a number of exemplary embodiments hereinbelow.
  • the roller body 51 is designed, on its outer circumference, with two spaced-apart ring-like protrusions 52 of which the diameter is approximately 90% of the diameter of the running roller 5 with the running ring 61 and in the case of which the distance between the outer side flanks is approximately 75% of the distance between the side flanks of the running roller 5 with running ring 61 .
  • This design ensures that, even in the event that the running ring 61 ruptures, the running roller 5 performs virtually the same function as the undamaged running roller 5 , and that emergency running properties are thus ensured.
  • the ring-like protrusions 52 are formed with a multiplicity of bores 53 which have the material of the running ring 52 passing through them.
  • the roller body 51 is of the width of the running roller 5 in the region of the hub and is designed to be somewhat narrower in the radially outer region, the roller body merging, in the direction away from there, into the ring-like protrusions 52 .
  • FIGS. 5 and 5 a illustrate a variant of the running roller 5 a in which the roller body 51 a is designed with just one annular protrusion 52 a .
  • the roller body 51 a is formed with a multiplicity of bores 53 a which have the material of the running ring 61 a passing through them. However, these bores are not absolutely necessary.
  • FIGS. 6 and 6 a illustrate a further embodiment of such a running roller 5 b , in which the roller body 51 b is designed with a cross-sectionally T-shaped ring-like protrusion 52 b.
  • the T-bar of the cross-section is located at the radially outer end.
  • the necessary emergency running properties are provided by the outer circumference of the T-bar and the lateral flanks thereof.
  • the T-shaped protrusion 52 b is enclosed by the running ring 61 b .
  • bores 53 b which pass through the T-shaped protrusion 52 b are provided in the bottom region of said running rollers 5 b. However, they are not absolutely necessary.
  • FIGS. 7 and 7 a illustrate a further embodiment of such a running roller 5 c .
  • the roller body 51 c is designed with a protrusion 52 c which runs in wave form over the circumference of the roller body 51 c.
  • This protrusion 52 c is also enclosed by a running ring 61 c.
  • the roller body itself that is to say without the running ring, has an outer diameter of at least 85% to 95%, preferably of 90%, of the outer diameter of the running roller, and the distance between the outer side flanks of the at least one ring-like or wave-form protrusion is at least 65%, preferably 75%, of the distance between the side flanks of the running roller.
