Definitions

  • the invention relates to a power transmission element for a drive on a sliding gate in the form of a rack for the engagement of a pinion of the drive motor, according to the features of the preamble of claim 1.
  • toothed racks made of steel have previously been used, in which lubrication had to be provided for corrosion protection reasons, so that constant maintenance was required.
  • a sliding device for a gate which has a motor which drives a pinion which engages in a toothed rack which is fastened to a gate by means of a sliding profile.
  • the invention has for its object to design a power transmission element of the type described above so that it is practically maintenance-free.
  • This arrangement not only has the advantage that by using a corrosion-resistant material for the tooth element maintenance is reduced, but also the advantage that a configuration can be created in which the tooth element is detachably connected to the carrier element, so that the tooth element can be replaced after a corresponding operating time. It is particularly expedient if the tooth element is divided into several sub-elements. This offers the possibility of providing a basic profile for the carrier element, for example an extruded or bent profile of a commercial type and length, so that this profile only needs to be cut to length for the respective application. By subdividing the tooth element into sub-elements of, for example, 15 cm, it is then possible to also produce force transmission elements of any length using standard elements within the grid predetermined by the length of the sub-elements.
  • the tooth element consists of an impact-resistant and abrasion-resistant plastic. This provides not only the required corrosion resistance, but also the required freedom from maintenance, since such plastic toothed elements can engage either with a corresponding plastic or metal pinion, without the need for lubrication. Another advantage is that the manufacture is simplified if injection-moldable and / or pourable plastics are used, since this enables the cost-effective production of partial elements in large quantities. Examples of suitable plastics here are polyacetals (POM), polyamides, polyurethane (PUR), polytetrafluoroethylene (PTFE) or plastics with comparable technical properties.
  • POM polyacetals
  • PUR polyurethane
  • PTFE polytetrafluoroethylene
  • the tooth element has a base to which the teeth are connected and that the base the teeth laterally limiting and firmly connected to these webs.
  • the lateral webs connected to the teeth result in a high level of structural stability, since the force is transmitted not only via the tooth base but also via the webs connected laterally to the teeth. This makes it possible to use smaller toothed elements with the same load capacity in terms of dimensions.
  • the base of the tooth element is provided on its side facing away from the teeth with a back groove running in the longitudinal direction. This results not only in a reduction in material consumption without impairing the strength, but also in the possibility of creating space for the arrangement of fastening means on the carrier element through this groove.
  • the carrier element is designed as a C-profile and that the tooth element is fastened in the C-profile.
  • the C-profile of the carrier element is provided at both ends with stop pieces for the tooth element and that at least one stop piece is designed to be braced in the longitudinal direction.
  • This configuration has the advantage in particular when using a plurality of sub-elements that the tooth element or the sub-elements only need to be inserted loosely into the C-profile and are then firmly clamped in the longitudinal direction via the stop pieces in the C-profile.
  • This also has the advantage that if the tooth element or a partial element is damaged, the partial elements can be pulled out in a simple manner by loosening a stop piece and replaced with new ones.
  • the C-profile is provided on its back side with through holes for screw bolts and that the width of the back groove of the tooth element corresponds to the width across flats of the head of the screw bolts to be used.
  • the bolts are pushed through from the open side of the C-profile and then the sub-elements are inserted, the back groove encompassing the head of the bolt used in a form-fitting manner.
  • This not only reduces the overall height of the C-profile to be used, but also creates an assembly aid, since the tooth element used also serves as a torque holder for the screw bolt, so that the required assembly nuts can be easily screwed on here.
  • the carrier element is provided on its side facing away from the tooth element with a hollow rail, on which electrical control lines are arranged and in which a sliding part is guided, which projects outwards through a longitudinal slot with a shoulder, the Approach can be attached to a fixed gate part and serves as a connection element for the control lines between the movable and the fixed gate part.
  • the carrier element is designed so that on the one hand the tooth element, but on the other hand also the control lines for such switching devices are arranged in one component, there is the possibility of a workshop pre-assembly, so that only the support element is screwed on site and the necessary Connections must be made. This also allows repairs to be carried out very quickly by replacing the complete assembly. Since the door part moves together with the support element, while the sliding part is fixed with its attachment serving as a connecting element, a possibility for a length compensation possibility corresponding to the length of movement of the door part must be given for the control lines accommodated in the hollow rail. This can either be caused by the control line being helically wound during manufacture, so that the control line can be elastically pulled apart in the manner of a coil spring and the required change in length between the movable gate part and the fixed extension part is ensured.
  • guide means for the in the hollow rail Control lines are arranged.
  • Such guide means can be formed, for example, by so-called cable drag chains, which are guided in the hollow profile.
  • the hollow rail is designed to be longitudinally divisible and part serves as a cover. This arrangement offers the possibility that there is free access to the control lines or the guide means for the control lines in the hollow rail even without having to dismantle the entire power transmission element, so that faults can be easily eliminated on site.
  • a sliding gate essentially consists of a gate element 1, which is guided in a sliding bearing arrangement (not shown here) and which is connected to a force transmission element 2.
  • the power transmission element 2 is designed as a rack and is connected to the pinion 3 of a drive motor 4.
  • a safety device for example in the form of a contact rail, by means of which it must be ensured that the drive motor is switched off immediately when the sliding gate closes as soon as the gate hits an obstacle.
  • the gate element 1 bears against a corresponding fixed pillar 6.
  • the cross section acc. Fig. 2 shows a preferred embodiment for the power transmission element.
  • the force transmission element 2 consists of a carrier element 7 in the form of a C-profile made of metal, preferably a stainless steel, which is firmly connected to the gate element 1 via screw bolts 8 and a shoulder 9.
  • a tooth element 10 is inserted into the carrier element 7, which is designed as a C-profile.
  • the tooth element 10 has a base 11 to which the teeth 12 are connected.
  • the teeth 12 laterally bounding webs 13 are connected, which are also integral with the end faces of the teeth 12, so that, as the perspective view in Fig. 4 shows, the base 11 with the side webs 13 and Teeth 12 form a box-like profile.
  • the teeth 12 are thus not only firmly connected to the base 11 with their base but also with their end faces, so that there is a high level of structural strength.
  • a back groove 14 (FIG. 4) which is formed by two longitudinal webs 15 in the illustrated embodiment.
  • the width of the back groove 14 is dimensioned such that it corresponds to the width across flats of the screw head 16 of the screw bolt 8.
  • the power transmission element is now constructed so that first the necessary through holes for the bolts 8 are drilled at the desired intervals, then the bolts 8 are inserted and then the tooth element 10 is inserted.
  • the tooth element 10 can be formed in one piece and inserted over the full length of the C-profile 7. However, it is cheaper to divide the tooth element into individual sub-elements that are inserted one after the other into the C-profile.
  • the inserted tooth element 10 then secures, as shown in FIG. 2, the screw head 16 of the screw bolt 8 both against falling out and against rotation, so that the fastening nuts shown can then be screwed on and tightened without auxiliary tools.
  • the C-profile 7 of the support element is provided at both ends with stop pieces 17 and 18 which are screwed into the profile and are firmly connected to the C-profile 7 via transverse screws 19.
  • the stop piece 17 is inserted and fastened first.
  • the bolts 8 and the sub-elements of the tooth element 10 are inserted into the C-profile in the manner described above.
  • a pressing piece 20 is inserted and then the stop piece 18 is connected to the C-profile.
  • the stop piece 18 is provided with an axially guided clamping screw 21, by means of which the partial element forming the tooth element in the C-profile can be firmly clamped via the pressing piece 20.
  • Fig. 3 also shows that without having to detach the support element from the gate part, simply by loosening the stop piece 18, the tooth element or individual sub-elements can be pulled out of the C-profile at any time and replaced by new ones.
  • Fig. 4 shows that the sub-elements for the tooth element are cast or injection molded from a plastic.
  • plastics such as polyacetals, polyamides, polytetrafluorethylene or even polyurethanes are particularly suitable, which have the required high strength but also good uniform properties.
  • the partial element which is in engagement with the drive pinion 3 when the sliding gate 1 is in the closed position consists of a metallic material.
  • the sub-element 22 in question is hatched. Since the drive motor 4 is designed as a worm gear motor and is therefore self-locking, the sliding gate cannot be moved against the motor by hand.
  • the arrangement of a metallic sub-element 22 also offers a gate lock for the area of the closed position, since it is only very tight It is difficult to destroy the toothing between the metallic tooth element and the metallic drive pinion even with a large lever tool.
  • Fig. 5 shows in a cross section a further embodiment for the power transmission element.
  • a hollow rail 23 is molded onto the C-profile 7, which is produced, for example, as an extruded profile.
  • the hollow rail 23 is designed to be longitudinally divisible, so that a removable cover part 24 is provided, which offers free access to the interior of the hollow rail.
  • the cover part 24 is designed so that a longitudinal slot 25 remains free, through which an extension 26 of a sliding part 27 is passed to the outside.
  • the approach 26 here forms a connection element for a control line which is guided in the hollow rail 23, which is connected to the contact rail 5 of the door on the one hand and via the approach 26 connected to a fixed gate part to a control and switching device connected to the drive motor 4 .
  • the hollow rail 23 can also have an essentially circular cross section with a longitudinal slot, so that the control line can be inserted directly into the hollow rail 23 as a helically-spring-wound element. In the closed position, the resilient winding is pulled apart, while in the open position, the resilient winding is contracted.
  • the C-profile 7 also offers the possibility of providing the pinion 3 of the drive motor 4 with at least one track and / or support rim 29 which bears against an edge 30 of the C-profile.
  • the drive motor 4 is mounted on a rocker so that the pinion 3 with its track edge is pressed against the C-profile with a pressure spring.
  • a stop on the rocker ensures that a minimum engagement between the pinion and the tooth element is retained.
  • a modified counter wheel can also be assigned to the pinion in this modified form, which runs on the upper side of the C-profile if the fastening means for the carrier element are designed accordingly.
  • the C-profile is "clamped" between the pinion and counter wheel, so that the motor mounted on the rocker and also connected to the counter wheel is always tracked by the counter wheel when, for example, the sliding gate is at a somewhat higher level due to deposits or ice formation on its running rails running.
  • the pinion is always in precisely defined engagement in the tooth element.
  • the tooth element is enclosed by the C-profile including the teeth in the illustrated embodiment and thus largely protected.
