Definitions

  • the invention relates to a switch tongue rolling device, in particular the transport part of said rolling device, which is also lubrication-friendly or even lubrication-free and almost completely eliminates the lubrication of sliding chairs.
  • the switch tongue must be lubricated, or extreme steering or steering force may then be required in the edge position.
  • the switch tongue In some depictions in the font DD - 65901 there is also a movement of the switches tongue perceptible in the entire path of the rolling bearing, this version is not explained in the description.
  • the bearing on a rolling element which is also load-bearing when fully loaded, would cause permanent deformations of the seat surfaces during a train passage.
  • bearings of the switch tongues on flexibly suspended rollers are known. Such a suspension or suspension fulfills the requirement of rolling bearings with low friction and with minimal lubrication, in which the total load is on the sliding chairs.
  • Some known solutions also have a variable lifting force of the switch tongue, for example DD - 56536, 61558, 66638 etc. In these cases, however, the change in lifting force appears to be constant and relatively slight. Also in the description of said patents one does not speak of a special meaning of the force required for lifting / levitation / or of a progressive change of this force during the advancing movement of the switch tongue. Here, too, a feed in a raised position and the lying on the ground are only accepted when the train passes through. Here too, the device has the disadvantage of an alternating resting of the switch tongue.
  • Said device consists of a holder of the same, which is fastened to the underside of the tongue support by means of hooks and clamps with a screw, furthermore an arm of the rolling device, connected by bolts to the aforementioned holder, the device arm being located on the opposite side of the tongue support without connecting bolts and is connected by means of spring bolts to the spring screw which rests on a spring supported on the holder of the rolling device.
  • the rolling or sliding element has at least two abutment points located between the arm pin and the tongue support, the first abutment point closer to the arm pin dividing the distance between the arm pin and the other abutment point in a ratio of 40:60 to 80:20; when the switch tongue rests on the tongue support, the switch tongue lies only on the other abutment point and the tongue base is at most 5 mm away from the first abutment point.
  • the bumps are preferably roller bearings, but can also be provided in a sliding, self-lubricating version.
  • Figure 1 shows a vertical cross-section through a device with roller bearings
  • Figure 2 shows a vertical cross-section through a variant with self-lubricating layer
  • Figure 3 shows a plan of the form with roller bearings.
  • Figure 1 shows the attachment of the device holder 3 to the tongue support 1 by means of the hook 15 and the clamp 5 with screw 6 .
  • the arm of the device 4 is connected by means of arm bolts 10 and at the same time the block with roller bearings, formed by bearings 12 on bolts 11 , and the switch tongue 2 carried by bearings 12 are connected.
  • the arm of the rolling device 4 is connected on the other side by the spring bolt 9 to the spring screw 8 and this is supported by a washer on the spring 7 resting on the arm of the rolling device 4 .
  • a slide support 13 is connected to the arm of the device 4 , the abutment points 16 and 17 of which are supported in turn on a housing with a hard, self-lubricating surface 14 , which is fastened in the foot of the switch tongue 18 .
  • Figure 3 shows the arrangement of the device arm 4 in the device holder 3 with arm bolts 10 and rollers 12 on bolts 11 .
  • the device works as follows: by hand or by means of a servo motor, the switch tongue is switched from free to the working position via the preferably roller bearing.
  • the base of the switch tongue rolls over the first or both joints and at the end of the feed, it is only supported via the second joint. This progressively increases the moment of the loading force acting on the device arm; this is lowered with a suitable spring setting, and the switch tongue lies lightly on the sliding chairs, if necessary, it is pushed a little towards the tongue support and locked by the feed mechanism.
  • the other switch tongue moves in exactly the opposite order.
  • a plain instead of roller bearing is suitable, for example, for hot operations where the internal lubrication of the bearings could fail.
  • the device described according to the invention is used for all types of switch tongues and for all track gauges. It can advantageously be installed as an additional device in existing switch blades. With their arrangement, they do not hinder the original design and can be connected in a very short time and without removing the other components of the switch tongue. In the case of long switch blades, several rolling devices can be used in series. The switch tongue rolling device was during heavy operation u. Tested at low speeds and proven to be reliable.
