Definitions
- the invention relates to an elevator installation according to the preamble of claim 1.
- Elevator systems are usually installed in a shaft of a building and are used to transport people or goods.
- the cabin movable in the vertical direction in the shaft is carried by suspension means, for example in the form of ropes or belts, the suspension means being connected to a drive for moving the cabin.
- the cabin and / or a counterweight connected to the cabin via the suspension element is connected to the suspension element via one or more deflection units.
- the car is assigned one or two deflection units and the counterweight is assigned a deflection unit.
- WO 2010/103165 AI a deflection with a freely rotatable about a rotation axis, mounted on an axis on a support pulley has become known, which - with respect to a central plane which is vertical to the axis of rotation of the pulley - a mirror-symmetrical design of the axis having.
- the axis formed by a cylindrical body has grooves on both sides, in which the carrier engages directly or indirectly via a holding part fixed to the carrier.
- the peripheral surface of the axis is interrupted by an outer adjacent to the respective groove planar portion which is supported on a bolted to the carrier, formed by a plate securing member.
- the safety elements have the purpose of ensuring a rotationally secure mounting of the axle.
- 2010/103165 allow the axis held in the support via the grooves to rotate the axis.
- the desired axial securing is not given, inadequate or achievable only by complex design solutions.
- the deflection unit for the elevator system should continue to be simple in design and manufacture and are characterized by a robust design.
- the axle arrangement and fastening according to the invention is used in the deflection unit assigned to the counterweight.
- the retaining means is formed on one side by an axle head integrally formed on the axle to form a shoulder-like abutment for the wearer.
- another holding means is used on the opposite side.
- the axis with the axle head is preferably made monolithic and consists for example of a metallic material.
- the axle may be a substantially rotationally symmetrical steel axle body.
- the axle thus has a mushroom-shaped configuration, the axle comprising the abovementioned axle head ("mushroom shield"), which is adjoined by an axial shaft in the axial direction such a rigidly connected to the axis holding Medium leads to a particularly high stability of the axle attachment.
- the axle head can simply be dimensioned so that a break or other destruction of the axle head is virtually impossible even with extremely strong mechanical stresses during operation of the elevator.
- the axle assembly with the mushroom-shaped axle body is easy to handle and allows easy and quick assembly and disassembly.
- At least the axle head and / or the holding means (arranged on the opposite side) for a rotationally secure mounting of the axle in a first life cycle can be fixed in a rotationally fixed manner with respect to the carrier by means of an anti-rotation means.
- the respective deflection unit can be operated optimally at least in the first life cycle.
- the deflection roller can be turned with low noise and with little wear.
- it may of course also be sufficient if the axle which is fitted in bearing receivers of the carrier is prevented from rotating during normal operation due to the significantly higher axle-carrier friction (in comparison with the rolling bearing arrangement, for example).
- At least one deflection unit is designed such that when a certain torque between the deflection roller and axis exceeds the anti-rotation means releases the corresponding (or the anti-rotation means associated) holding means and the axis in a second life cycle rotatable in the carrier between the holding means is stored.
- the lifetime of the axle attachment of the deflection unit is thus characterized by two life cycles. In the first life cycle, which roughly corresponds to a normal state, the axis in the carrier can not be rotated. In the subsequent second life cycle, which corresponds approximately to an emergency operating state, the axle can be rotated in the carrier, whereby the axial securing of the axle in the carrier is still ensured.
- the diverter unit By dividing the service life into two cycles, the diverter unit can also be better monitored. In the second life cycle, it may happen that the axle eats itself by wear in the carrier and a more or less vertically extending slot in the carrier arises. This phenomenon is easily observed, which simplifies monitoring of the diverter for maintenance personnel.
- the anti-rotation means could for example have an action mechanism that can be triggered when exceeding the aforementioned excessive torque and thus releases the retaining means. But it may be particularly advantageous if the anti-rotation means is designed as a predetermined breaking element.
- Such an anti-rotation means may comprise, for example, a comparatively tightly dimensioned screw which breaks under the action of high shear forces when the predetermined torque between deflection roller and axle is exceeded. Of course, however, other predetermined breaking elements would be conceivable.
- the axle head has a preferably predetermined by a flat surface anti-rotation portion which is supported on a securing member secured to the carrier.
- the anti-rotation portion may be arranged in the peripheral region of the axle head.
- the axle head may also have a projecting in the radial direction anti-rotation portion, which is fixed for example by means of a screw on the carrier.
- the securing member may be a preferably formed by a plate body which is attached via at least one screw on the carrier.
- This screw can be designed as a predetermined breaking element, which break under the action of excessive shear forces and so the rotation of the axle can be lifted.
- the securing member is secured by a single screw on the carrier.
- the single-screw arrangement makes it particularly easy to set the desired breakaway value at which the anti-rotation lock is to be removed.
- the screw can be aligned so axially parallel to the axis that at least for a first life cycle, in which the axis is arranged rotationally fixed in the carrier, screw and axis lie on a surface normal of the anti-rotation portion. Further, it may be advantageous if the holding means is formed on at least one side by a separate component. A simple assembly and disassembly of the deflection is ensured in this way.
- the holding means may be formed on at least one side by a holding part surrounding the axis in the radial direction.
- the holding part surrounding the axle can be simply applied to the axle and removed again. It may be particularly advantageous if the holding part is designed horseshoe-shaped or annular.
- the horseshoe-shaped holding part can have plane flanks and the axis running complementary to the flanks and preferably provided by chamfering form-fitting sections.
- the horseshoe-shaped holding part can be easily applied from the outside in the radial direction on the axis.
- the axle may have a groove for receiving the horseshoe-shaped holding part.
- the groove ensures precise positioning of the holding part on the axle.
- the holding part may be provided a surrounding the axis in the radial direction securing part, which is preferably connected by screws to the holding part.
- the securing part can be designed annular.
- FIG. 1 shows a simplified representation of an elevator installation in a side view
- FIG. 2 shows a detail of a cross section through a deflection unit of the elevator installation according to FIG. 1,
- FIG. 3 shows a perspective view of one side of the deflecting unit from FIG. 2 in a partially exploded view, the other side of the deflecting unit from FIG. 2, and
- FIG. 5 shows an exploded perspective view of the axle arrangement for the deflecting unit according to FIG. 2.
- FIG. 1 shows a generally designated 1 elevator system in a highly simplified and schematic representation.
- the elevator has a vertically up and down movable cabin 2 for the transport of persons or goods.
- Supporting means 5 for supporting the car and a counterweight 4 may be a rope or a plurality of ropes. Of course, other support means are conceivable, for example in the form of belts.
- the car 2 and the counterweight 4 are each connected via deflection units 7, 8, 9 with the support means.
- a drive 6, for example a traction sheave drive is used, which is arranged by way of example in a separate machine room in the region of the shaft head.
- the elevator installation 1 shown in FIG. 1 is designed in a 2: 1 suspension configuration.
- other suspension variants for example, 1: 1, 4: 1, etc.
- a deflection unit could also be arranged in the region of the car roof.
- FIG. 2 shows the region of the axis of rotation of the deflection unit 9 associated with the counterweight, on which the counterweight (not shown here) is suspended via the carrier 13.
- the deflection unit shown here could also be associated with the car (7, 8, see Fig. 1) or even be arranged at another location in the elevator installation.
- the deflection unit 9 comprises a deflection roller 11, on the circumference of which the support means (not shown here) is guided and deflected.
- the deflection roller 11 is connected via a bearing 12 with an axis 10 and freely rotatably supported on the axis 10.
- the bearing 12 may include one or more rolling bearings as required.
- the axle 10 is fixed to a carrier 13.
- the carrier 13 is connected to the (not shown) counterweight.
- the carrier 13 has two mutually opposite walls 25 and 26, which are each provided with a bearing receptacle, through which the axis 10th is performed.
- the axle 10 is secured in the axial direction on both sides.
- the holding means for axially securing the axle to the carrier is formed by an axle head 15 integrally formed on the axle 10, which defines a shoulder-like stop.
- the axial securing is achieved by a holding part 14 attached to the axle.
- the securing part designated 20 is used for securing the holding part 14 in the position shown.
- the axis 10 is rotatably connected to the carriers 13, wherein the rotation only acts on one side of the axle. This rotation ensures the designated 16 fuse element, which is bolted to the carrier 13.
- the axle head 15 has a predetermined by a flat surface Vermostechnischsabschmtt 21, which is supported on a securing member 16.
- the securing member 16 is secured to the carrier 13 via a screw connection.
- the holding part 14 is designed in the shape of a horseshoe.
- the horseshoe-shaped holding part 14 has mutually opposite, parallel flanks 18, which cooperate with complementary form-shot portions 19 and thus ensure a rotationally fixed fixation of the holding part 14 in the finished assembled position.
- the holding part 14 surrounds the axis 19 with respect to the radial direction predetermined by the axis.
- the securing part 20 is designed annular and contains four to the threaded holes 27 corresponding through holes 28 through which the screws 23 are inserted.
- the holding part 14 is provided with threaded holes designed as receptacles for mounting screws 23.
- the holding part could be ring-shaped and the securing part horseshoe-shaped.
- the securing member 16 is formed by a plate-like body. Instead of the illustrated in a plan view square plate also other shapes for the component 16 could be selected. It should be noted that the securing member 16 has an edge or portion which cooperates with the anti-rotation portion 21 of the axis 10 and rests against this. The securing member 16 has a hole 30 through which the screw 17 can be inserted and then screwed into the threaded bore in the wall 26 of the carrier 13. The substantially cylindrically shaped axle head has an anti-rotation portion 21 created by chamfering.
- the screw 17 is a predetermined breaking element, which under the influence of excessive shear forces, for example, when the pulley suddenly and unforeseen can not turn and a certain torque between pulley and axle is exceeded, breaks and thereby the rotation of the axle 10 is released ,
- the mentioned torque can be easily adjusted by the choice and dimensioning of the screw 17. Thanks to the two lateral holding means, ie the axle head 15 on one side and the holding part 14 on the other side, the axle is still secured against undesired movement in the axial direction. When the service person discovers the axle rotating in the carrier, it can take repair or repair measures. After the release of the rotation, the axis 10 is thus rotatably received in the carrier in a second life cycle of the deflection.
- the axle head could also have a rotation-preventing section projecting in the radial direction or a special shaping in the circumferential area.
- the plate body designated by 16 in FIG. 4 could be welded to the axle head.
- This anti-rotation means integrated with or in the axle head would have to be fastened to the carrier only by means of a screw, analogously to the exemplary embodiment according to FIG.
- the special anti-rotation means exemplified in FIG. 4 are not required. Because it may be sufficient if the fitted in bearing mounts of the carrier axis is prevented due to the much higher friction between the axle and carrier, to rotate during normal operation in a cabin ride.
- the axle head of the embodiment according to Figure 4 could in this case a cylindrical outer shape without chamfering and the bearing unit would have no securing member. After a bearing defect, the friction in or in the rolling bearings would be greater than that between the axle and the carrier, whereupon the axis in the Can turn carrier. Screw 17 and axis 24 lie on a surface normal of the anti-rotation portion
- FIG. 5 shows the individual components of the axle arrangement including the axle 10 with the axle head 15 formed on the axle, the securing member 16, the holding part 14 and the securing part 20 designed as a plate.
- the axle 10 is evidently designed mushroom-shaped, the axle head 15 being the "
- the axle shaft 24 adjoining the axle head in the axial direction has a smaller diameter D1 than the diameter D2 of the axle head 15.
- the axle shaft 24 can be fitted in corresponding bearing receptacles of the support easily made of a metallic material (eg steel) by machining processes (turning, milling, etc.).
