Definitions

  • the rolling disc can also be used for certain applications have a circular outer contour, with or without a flat spot, which simplifies and cheapens their manufacture.
  • the rolling disc and the work eccentric can be inexpensive to manufacture be carried out as a one-piece part.
  • FIG. 1 denotes a console, on the left outside an abutment 3 and on the right side a bearing journal 2 are inextricably linked to it.
  • An actuating element 21 can be rotated via a slide bearing bush 23 arranged.
  • the actuating element 21 consists of a larger one Rolling disc 4 and a smaller one, with the rolling disc 4 non-rotatably connected work eccentric 5.
  • work eccentric 5 itself consists of two eccentric discs, which are on both sides of the Rolling disc 4 are arranged in the same position to each other.
  • the rolling disc 4 has a flat point, whose center is designated as zero point 4.1 and which in the Ready position parallel to the sliding surface of a Guide rail 8 stands, and a rolling contour 4.2, the shape controls the braking force.
  • the flat spot is here essential part of the shape of the rolling contour 4.2, because with it a accelerated application of the braking effect after triggering the Safety gear is reached.
  • a rolling disc 4 without Flat point is the zero point 4.1 of the guide rail 8 on next lying point on the circumference of the rolling disc 4 in the Ready position of the safety gear.
  • At the Working eccentric 5 is the greatest distance from the center 12 of the Bearing pin 2 referred to as top dead center 5.1.
  • the zero point 4.1 of the rolling disc 4 and the top dead center 5.1 of the Work eccentrics are at an angle to each other alpha.
  • the passive brake shoe 7 On the left side of the guide rail 8 is to this spaced, the passive brake shoe 7 arranged.
  • As vertical Stops serve a stop jaw 14 at the top and bottom vertical play distance 15 between the end faces of the Passive brake shoe 7 and the inner stop surfaces of the Stop jaws 14 is an important measure and also serves easier release of the safety gear after braking.
  • the passive brake shoe 7 is connected to two guide bolts 10, which are guided in the abutment 3. Compression springs 9 and one not Shown adjustment mechanism for the spring preload on the Guide bolts 10 hold the passive brake shoe 7 in the Ready position and generate the braking force when triggered Safety gear.
  • Fig. 3 the safety gear is in the engagement position shown.
  • a trigger device not shown, has that Actuator 21 rotated slightly to the left, whereupon the Rolling disc 4, or its knurled rolling contour 4.2 with the Guide rail 8 frictionally connected and rolling on the guide rail 8, from the elevator still moving is rotated. It will then be the entire safety gear pulled to the left and the passive brake shoe 7 comes through Cancellation of the passage game, in contact with the Guide rail 8.
  • the active brake shoe 6 still has one Distance b to the guide rail 8 and is on the braking not yet involved.
  • FIG. 10 shows this as a further variant Actuator 21 in multi-part and adjustable Execution.
  • Fig. 10 there is a dashed line circular arc-shaped slot 16 shown in the rolling disc 4, which extend over an angle between 30 ° to 60 ° can.
  • a coupling pin 17 With a coupling pin 17, the two parts of the Work eccentric 5 connected so that they always the assume the same position to each other, or only synchronously with each other are angularly displaceable relative to the rolling disc 4.
  • By rotating displacement of the work eccentric 5 relative to the The rolling disc 4 can be in the region of the arcuate slot 16 any angular position can be set.
  • a Tensioning screw 18 can be a set angular position of the Work eccentric can be fixed relative to the rolling disc 4.
  • FIG 11 shows in cross section the clamping screw 18 and the circular slot 16.
  • the whole safety gear is in a known manner from the Cabin support structure held so that when engaged the safety gear necessary for centering the same to the guide rail 8 is made possible.
