Definitions
- the invention relates to a sliding guide shoe for an elevator for transporting people or goods according to the preamble of claim 1.
- Slide guide shoes are often used to guide elevator cars. Elevator systems in buildings generally have a vertical elevator shaft in which a guide rail is arranged on each of the shaft walls lying opposite one another. Slide guide shoes arranged on the elevator car have slide surfaces facing the guide rail, which slide with little play along the guide rail. Sliding guide shoes which have inserts with sliding surfaces are known and in use, the inserts often being designed as profiles with a U-shaped cross section.
- a sliding guide shoe with a guide shoe housing and a two-part insert inserted in the guide shoe housing is known.
- the insert has truncated cylindrical pins which engage in bores in the guide shoe housing and thus secure the insert in terms of its position.
- the sliding guide shoe for an elevator for transporting people or goods essentially comprises the following two components: a guide shoe housing and an insert for guiding an elevator car or a counterweight.
- the guide shoe housing serves, on the one hand, to hold the insert and, on the other hand, to connect it to the elevator car or to the counterweight.
- the guide shoe housing has, for example, openings through which fastening screws can be passed, with which the guide shoe housing can be screwed to the car or to the counterweight.
- the guide shoe housing can comprise a channel-like receptacle in which the insert, which at least in the inserted state is designed as a profile with a U-shaped cross section, is inserted or insertable.
- the guide shoe housing can have two mutually opposite, parallel side wall sections and a bottom section connecting the side wall sections.
- the bottom section and the side wall sections protruding away from the bottom section at a right angle form a “U” in section.
- the guide shoe housing can thus be formed by a U-shaped profile.
- the guide shoe housing can, however, also have other shapes.
- the common shape known from DE 203 15 915 Ul for example, with a plate-like housing base and the two side wall sections protruding approximately centrally from the housing base and forming a groove to form the channel-like receptacle can also be used for the guide shoe housing.
- the guide shoe housing can consist of a metallic material (e.g. steel). It is also conceivable to manufacture the guide shoe housing from a high-strength plastic material e.g. PE, PP, PA, PS, PES, POM, PEEK, TPEs or fiber-reinforced plastic.
- a high-strength plastic material e.g. PE, PP, PA, PS, PES, POM, PEEK, TPEs or fiber-reinforced plastic.
- the insert which is inserted or can be inserted in the guide shoe housing, is used to guide the elevator car along one that extends in the travel or longitudinal direction Guide rail or for guiding the counterweight along a guide rail extending in the travel or longitudinal direction.
- the guide shoe housing has at least one bore.
- the insert has at least one pin which corresponds to the bore, engages in the bore or is received therein in a form-fitting manner.
- a hole is understood here to mean a round or possibly non-round recess or opening in the guide shoe housing.
- the bore does not necessarily have to be created by drilling or another machining process.
- the bore could, for example, also be created during casting or another primary molding process during the manufacture of the guide shoe housing.
- the at least one bore can preferably be provided or attached to one and particularly preferably to each side wall section.
- the insert can thus preferably have at least two pegs, with one peg in each case being positively received or receivable in a respective bore of a side wall section.
- a profiled pin is provided as the pin to achieve a buffer function, the undesired vibrations described at the beginning can be efficiently absorbed, which has a positive effect on driving comfort.
- the insert can still be produced easily and inexpensively. Another advantage is that the effort for assembling and disassembling the novel insert with respect to the guide shoe housing remains small, even in comparison to conventional inserts. Existing sliding guide shoes can also be easily retrofitted, since only the previous insert has to be replaced with the new insert with the profiled pins.
- the insert is preferably designed in several parts, the multi-part insert comprising a sliding element provided for sliding contact with the guide rail and a damping element.
- the profiling of the profiled pin is assigned to the damping element.
- the sliding element is that element which is used for the actual guidance of the elevator car or the counterweight along the guide rail.
- the sliding element can have sliding surfaces or areas which, when the sliding guide shoe is installed in the elevator and ready for use, slide along the guide rail with little play when traveling in the cabin. To optimize driving comfort, it is advantageous if the aforementioned damping element is arranged between the guide shoe housing and the sliding element.
- an elastic plastic in particular a thermoplastic elastomer (TPE) or a plastic made of crosslinked elastomers, can be used for the damping element.
- TPE thermoplastic elastomer
- the damping element can be made of SBR, TUR, EPDM, NBR, NR, for example.
- the damping element itself already has damping properties due to the appropriate choice of material, which promotes low-vibration and low-noise travel in the cabin. The particularly good insulation results that have now been achieved, however, are mainly due to the profiling of the pin.
- the sliding element can preferably be made of a plastic which is characterized by a low coefficient of friction with regard to the sliding function. In addition to good sliding properties, the plastic should preferably also have sufficiently high strength, rigidity and hardness for the sliding element.
- the sliding element can be made from POM or UHMW-PE, for example.
- the guide rails are usually moistened with oil or another lubricant to ensure safe and trouble-free operation of the elevator.
- sliding guide shoes with sliding elements made of POM or UHMW-PE thanks to the good dry-running properties of these plastics, it is even possible to dispense with lubrication of the guide rails if necessary or, in special situations, at least temporarily without lubrication. Sliding elements with particularly good sliding properties also ensure a jolt-free approach to the elevator car and almost noiseless running during a car journey.
- the at least one pin can have a profiled outer contour created by indentations and / or elevations.
- the pin has an advantageously increased local elasticity in the contact area with the guide shoe housing.
- the vibration isolation achieved thanks to the pin profiled in this way has a positive effect on driving comfort when traveling in the cabin.
- the at least one pin for forming the profile has a star-shaped cross section. It has surprisingly been found that the star-shaped geometry of the tenon construction is particularly good is suitable for preventing structure-borne noise from the insert on the guide shoe housing.
- the at least one pin for forming the profile has a knurling on its outer surface.
- punctiform elevations elongated elevations can also be advantageous.
- the pin can each extend in an axial direction.
- the profiling of the pin likewise extends in the axial direction.
- the star-shaped buffer described above can be formed in the pin.
- the profiling of the pin can, for example, have a straight or helical course.
- the at least one pin can have ribs or webs directed radially outward, preferably evenly distributed over the circumference, in order to form the profiling.
- ribs or webs that are created by comparatively thick-walled elevations, it would also be conceivable that the profiling could have a lamellar structure.
- the ribs or webs can each have a trapezoidal shape in cross section.
- the cross-sectional shape for the ribs or webs can preferably be an essentially isosceles trapezoid.
- the long base side of the trapezoid can be arranged on the inside in the radial direction and the short base side can be arranged on the outside.
- the ribs or webs could also have rectangular or triangular or other shapes in cross section.
- the ribs or webs can each have two opposing side flank sections and head sections connecting the two side flanks to one another, the side flank sections being straight in cross section, but possibly also convex or even concave can.
- the ribs or webs can each have an arcuate cross-section radially towards the outside.
- the aforementioned head sections can thus have an arc shape in cross section.
- the arch shape ensures that the pin fits perfectly into the bore of the guide shoe housing.
- the at least one pin can be chamfered or rounded in the area of its front edge for easy insertion into a bore in the guide shoe housing.
- the at least one pin can be designed essentially as a hollow cylinder or tubular.
- the profiling for the pin could be created by an essentially hollow cylindrical or tubular component, e.g. by an annular, externally profiled separate buffer element.
- the sliding guide shoe comprises a two-part insert.
- the two-part insert consists of a sliding element and a damping element. Both the damping element and the sliding element can each be produced using injection molding processes. However, other manufacturing processes, such as machining processes, are also conceivable.
- the damping element can have an annular buffer element, on the outside of which the profiling is provided and on the inside of which a hole is provided.
- the sliding element can accordingly have a holding cam, which is preferably designed as a solid cylinder and which is received or receivable in the hole.
- Such a sliding guide shoe is characterized by an optimal combination of sliding and vibration isolation properties.
- the buffer element can preferably be an integral part of the damping element and form a one-piece component with it.
- the ring-shaped buffer element can be molded onto a U-shaped profile body and monolithically connected to it.
- FIG. 1 shows a perspective view of a device according to the invention
- FIG. 2 shows a damping element of the sliding guide shoe according to FIG. 2 in an enlarged perspective illustration
- FIG. 3 shows a plan view of a pin, received in a bore of a guide shoe housing, of an insert of the sliding guide shoe according to FIG. 1 in a greatly enlarged partial view.
- the elevator can be an elevator car which is guided vertically up and down in an elevator shaft between two guide rails (not shown) as finear guides. At least the slide guide shoe described in detail below for guiding the elevator car can be arranged on each side of the elevator car. For optimal guidance, elevator cars generally have four (two on each side) or more sliding guide shoes.
- a counterweight also not shown, which is connected to the elevator car via suspension means in the form of ropes or belts, can have these sliding guide shoes for guiding the counterweight on counterweight guide rails.
- the sliding guide shoe assigned to the elevator car or the counterweight can have a groove for the guide which surrounds a tongue of a guide rail assigned to the elevator shaft.
- This spring can be an extension of a profd.
- the guide rail can be formed by a T-profile.
- the T-profile can, for example, be a full-walled steel profile manufactured by rolling.
- the guide rail can also consist or have other metallic materials (eg aluminum), manufacturing processes or profile shapes. For example, metal profiles manufactured using the extrusion process or rails bent from sheet metal can be used as guide rails.
- the sliding guide shoe 1 comprises a one-piece guide shoe housing 2 and an insert 3 inserted therein.
- the insert 3 is constructed in two parts and has a sliding element 5 facing the guide rail as the inner insert part and a damping element 4 as the outer insert part.
- the sliding element has sliding surfaces or areas which slide with little play along the guide rail when the cabin is in motion.
- the sliding element 5 is designed to be stiff compared to the damping element 4.
- it is made of a plastic that is characterized by a low coefficient of friction such as PTFE, UHMW-PE. A material with a low stick-slip tendency is preferred, i.e. a small or minimal difference between sliding and static friction.
- Such sliding elements could also be used as guide rails in the case of rails with little or no oil, and in particular sheet metal rails.
- an elastic plastic in particular a thermoplastic elastomer (TPE) or a plastic made of crosslinked elastomers
- TPE thermoplastic elastomer
- the damping element 4 can be made of SBR, TUR, TPU, EPDM, NBR, NR, for example. It is also conceivable to use foamed damping elements.
- the guide shoe housing 2 in which the previously mentioned channel-like receptacle forming the channel-like receptacle 3 is inserted, is connected to the elevator car or the counterweight.
- the guide shoe housing 2 is designed as a comparatively simply designed metal profile with a U-shaped cross section.
- the guide shoe housing 2 has two mutually opposite, parallel side wall sections 17 and a bottom section 18 connecting the side wall sections.
- the bottom section 18 and the side wall sections 17 protruding away from the bottom section at right angles can be seen to form a “U” in section.
- one of the side wall sections 17 for forming a fastening area 19 with regard to the connection to the elevator car or to the counterweight is extended.
- the guide shoe housing could, however, also have other shapes; For example, housing shapes as they are known and familiar to the person skilled in the art, for example from DE 203 15 915 U1.
- the guide shoe housing 2 has two bores 7, which are located opposite one another and which are arranged in the parallel side wall sections 17 of the guide shoe housing and into which each pin 6 engages.
- the pin 6 consists of an annular buffer element 8 assigned to the damping element 4 and a retaining cam 13 assigned to the sliding element 5, the retaining cam 13 being received in the hole of the buffer element 8 designated by 12.
- the buffer element 8 of the pin 6 has a profiled outer contour that is created by elevations and forms a star. The vibration isolation achieved with these profiled pins 6 can meet high demands in terms of driving comfort in a simple and inexpensive manner.
- the profiled pin 6 described in detail below is not only advantageous for two-part inserts for sliding guide shoes.
- a pin 6 profiled in this way or similarly could also be used in sliding guide shoes with one-piece inserts, i.e. in inserts which only consist of the sliding element and do not require a damping element.
- the sliding element would be equipped with the profiled pins.
- the damping element 4 has a U-shaped profile body 10.
- the damping element 4 can, for example, be an injection molded part.
- Two buffer elements 8 are formed on the profile body 10, which form a one-piece, monolithic component with it.
- the respective pin 6 has a star-shaped cross section to form the profile.
- the profiling of the pin 6, which extends in an axial direction, has webs 11 which are evenly distributed over the circumference and are directed radially outward.
- the webs 11 extend in the axial direction.
- the webs 11 and thus the profiling could also have a helical course.
- the pins 6 are chamfered for easy insertion into the bores 7 in the region of its front edge.
- the webs 11 of the star-shaped buffer are each in Cross-section have a trapezoidal shape.
- the trapezoid is obviously an isosceles trapezoid.
- the webs 11 each have two mutually opposite side flank sections 14 and head sections 15 which connect the two side flanks 14 to one another and which define the short base sides of the trapezoids.
- the head sections 15, however, are not straight in cross-section, but have a complementary arc shape for a favorable, form-fitting reception in the round bore 7.
- the holding cam 13 of the sliding element 5 is designed as a solid cylinder in the present case.
