Definitions
- the invention relates to a device for locking the end positions of movable switch parts, in particular movable switch frogs, in which two parts which are axially displaceable relative to one another can be displaced in a position which is coupled to one another in at least one direction of movement in a positively or positively locking manner, the parts displaceable relative to one another by a tube and a rod guided in the tube are formed and are at least partially arranged in a stationary outer tube and the locking members interact with the axially displaceable parts and the outer tube and can be moved in the radial direction into a locking position in a recess or inner ring groove of the outer tube are.
- Such a device for locking movable switch parts has already become known in EP 603 156 B1, in which the parts which are displaceable relative to one another are formed by a tube and a bolt guided in the tube and the locking members were designed as balls or rollers which can be displaced in the radial direction.
- AT 405 925 B has already proposed to store the balls in an expandable ring or in a ring consisting of segments.
- the ring or the ring segments formed a kind of ball cage, and this ring or the ring segments allowed the absorption of high locking forces without premature impairment of function.
- the design according to the invention essentially consists in that the locking members are formed by rings or ring segments, the essentially square or rectangular cross section of which is chamfered on its two inner sides to form surfaces which converge obliquely to the axis.
- rings or ring segments which, at least on their inside, have surfaces converging obliquely to the axis on both end faces, can ensure that, during the expansion of the rings or ring segments, surface contact is ensured, via which. Actuating forces or holding forces, which lead to a widening or compression of the rings or ring segments, can be absorbed without the risk of plastic deformation. Plastic deformations are thus reliably avoided even during the changeover process, and the inclined surfaces in the manner of wedge surfaces for moving the rings into the locking position are effective. At the same time, the number of components required is eliminated due to the omission of the balls and the fastening required for the balls.
- this training can also be used for several locking levels and in particular for the adjustment of movable switch frogs, in which high actuating forces and high locking forces have to be absorbed and the locking is required in two different positions. With such multiple locking levels, the improved stiffness and the improved section modulus of the inner tube due to the smaller cross-sectional weakening is of particular importance.
- a preferred embodiment of the device according to the invention • forming taken so that the arrival 'chamfering angle ( ⁇ ) of the conical inclined surfaces between 20 and
- the inward displacement of the rings or ring segments can be promoted by the use of springs which extend over the circumference of the ring segments.
- the inward movement may also be initiated by an analog outer chamfer ", where the configuration is devised so advantageously provided that the chamfer at the inner and outer circumference of the rings or ring segments is provided'.
- the rings or ring segments can be designed to be expandable against the force of a spring.
- the design is such that the expandable ring consists of at least 3, preferably 4, segments connected by a circumferential tension spring.
- rings or ring segments which can be expanded outwards against the force of a spring, in such a way that the end faces, which are essentially normal to the closure axis, or the flanks of the inclined surfaces in the respective outer or inner position of the Segments are in surface contact with the counter abutment surfaces of the pipes and / or rods which are displaceable relative to one another, whereby, as already mentioned, inclined surfaces can also be used in the outer layer.
- Optimal surface contact between the ring or the ring segments and the rod is achieved in that the curvature of the inner surfaces of the rings or ring segments corresponds to the curvature of the outer rod diameter.
- a further improvement is' when, as it corresponds to a preferred development, at least partially corresponds to the curvature of the outer surfaces of the rings or ring segments to the curvature of the inner diameter of the réellerohrers.
- FIG. 1 shows a first displacement position of rings or ring segments with the locking of an end position on the right in the drawing
- FIG. 2 shows the design according to FIG. 1 during the changeover process
- FIG. 3 shows the locking in FIG the left end position, as is required for switch frogs
- FIG. 4 showing a section along the line IV-IV through locking members designed as ring segments.
- an inner tube 2 and a rod 3 are guided in an outer tube 1 so as to be movable relative to one another.
- the inner tube 2 has radial openings 4.
- grooves 5 are provided, into which rings or ring segments 6 are immersed in the locking position.
- the ring segments 6 are shifted outwards, they run up on a section 7 of the inner rod 3 which is designed with a larger diameter and are shifted outwards in this way and are immersed in a first groove 5 of the outer tube 1.
- the rod 3 has turned-out areas 8, into which the rings 6 can dip during the adjustment process and in this way become disengaged and thus get into a position into which displacement can take place without locking. This is illustrated in Fig. 2.
- Fig. 3 the displacement of the rod 3 relative to the tube 2 is shown in the second end position, in which the locking members 6 have been moved into the corresponding second groove 5 of the outer tube.
- the adjustment process and thus the widening or the inward displacement of the ring segments 6 or the elastic ring 6 is achieved via inclined surfaces 9 on the end faces of the rings, which interact with corresponding inclined surfaces 10 of the rod or 11 in the recesses in the outer tubes 1.
- a surface contact is maintained along each of these conical inclined surfaces 9, 10 and 11, the chamfering angles ⁇ being chosen such that a corresponding inward or outward displacement is easily accomplished.
- the rings can be designed as ring segments, as shown in FIG.
- the curvature of the inner surfaces 13 of the rings or ring segments is adapted to the curvature of the outer rod diameter. Existing holding and vibrating forces can thus be absorbed in a way that is gentle on the components.
