Definitions
- the invention relates to a drive belt according to the preamble of claim 1.
- Drive belts are used in many applications and areas to drive and transmit power in work machines, means of transport, vehicles, etc., both as revolving drive belts in a pull belt drive and as drive belts of finite length in a linear drive or in an elevator system.
- parts of the respective device are moved with the help of the drive belts used there, for example in the case of a carriage of a work machine that moves in several directions, such as a milling machine, a stacker crane or even a driven print head of a 3-D printer.
- a so-called “cable drag” is also carried, essentially between the moving part of the machine and the drive or the central control device, which also carries the signals from the fixed operating devices connected there are processed.
- the term “cable drag”, originally a company name, is now used in the sense of a generally understandable generic name and refers to an energy chain with which longer cables, energy supplies and control lines are tracked on supporting, movable, chain-like holders of a moving machine or a mobile device.
- the cable drag here travels with the moving part of the machine, may also have to be redirected and requires appropriate installation space.
- various embodiments of sliding contacts can be used, for example in the form of current-carrying rails. Sliding contacts are particularly sensitive to contamination, which is why maintenance of the sliding contacts for reliable power and/or signal transmission is very complex and expensive.
- EP 3 462 055 B1 discloses an elevator system with a carrying belt as a drive belt with tension members for signal or data transmission.
- the signals or data are fed in or read out between signal line elements and further lines or signal processing devices via contacts at the respective end connection or fastening points of the signal line elements via a cable clamp.
- the method for contacting the tension members is very complex, since each individual tension member must be manually freed from the surrounding elastomeric material before electrical contact is made with the cable clamp. Such complex contacting of the tension members leads to correspondingly high manufacturing costs.
- the invention is based on the object of providing a drive belt in which the tension members are contacted quickly and/or cost-effectively and/or can be automated.
- the present application relates to a drive belt, comprising a first line element embedded in a polymeric material for transmitting electrical energy, the first line element being formed by at least one tension member extending in the longitudinal direction of the drive belt, preferably a plurality of tension members arranged parallel to one another extending in the longitudinal direction of the drive belt is formed.
- the drive belt can be designed, for example, as a toothed belt, flat belt, V-belt or V-ribbed belt.
- the drive belt may be an open drive belt with a predetermined length and two ends. In a particularly advantageous manner, the drive belt can be provided in any length by cutting, without incurring costs for individual tools for the production of a length-specific drive belt.
- the tension member which can be made of an electrically conductive material, preferably metal, can also carry current in addition to the actual task of power transmission.
- power can be conducted from an energy source via the drive belt to a consumer, for example an electric motor of an actuator, without the need for additional cables to carry power.
- the drive belt may preferably be formed as a finite section having a predetermined length with a first end and a second end.
- the polymeric material of the drive belt is a polyurethane.
- the drive belt can be designed as a toothed belt, V-belt or V-ribbed belt.
- the drive belt has at least one contacting element to which the first line element is electrically connected at the end.
- the drive belt can preferably have the contacting element at the first end and at the second end. It turns out to be particularly advantageous that the contacting element provides electrically conductive contacting of the tension member can be done without manually stripping the tension member from the polymeric material surrounding the tension member. It also proves to be advantageous that an interface can be provided via the contacting element, with which the first line element or the tension member can be connected in an electrically conductive manner to further devices for feeding in and/or drawing current.
- the contacting element has at least one pair, preferably a plurality of pairs arranged in the transverse direction with fork-shaped tines extending in the vertical direction for receiving at least one tension member extending in the longitudinal direction of the drive belt, preferably a plurality in the longitudinal direction of the drive belt extending tension beams arranged parallel to one another.
- the contacting element is inserted into the polymeric material in a vertical direction. Preferably it can
- Contacting element have pairs of fork-shaped prongs in the number of tension members present.
- the contacting element can be electrically conductively connected to the tension member of the drive belt without the tension member having to be freed from the polymeric material of the drive belt.
- the distance between two fork-shaped tines of a pair in the transverse direction from one another can at most correspond to the diameter of the tension member.
- the distance between two fork-shaped tines of a pair in the transverse direction preferably corresponds to 80 percent of the diameter of the tension member.
- a particularly good electrically conductive contact can be established between the tension member and the contacting element when the distance between two fork-shaped prongs is smaller than the diameter of the tension member.
- a possible deformation of the tension member to the distance between the pair of fork-shaped tines between which the tension member can be accommodated advantageously increases the contact area between the tension member and the pair of fork-shaped tines of the contacting element.
- the pairs of fork-shaped tines can be arranged from one another at the distance between the tension members be. In this way it can be ensured that each pair of fork-shaped tines is assigned a feed carrier and/or the tension carrier is not damaged when the contacting element is inserted into the polymeric material, the drive belt is not damaged and/or the position of the tension carrier in the drive belt is changed.
- a pair of fork-shaped tines can also accommodate or contact several tension members.
- the polymeric material and/or the contacting element can be heated.
- the polymeric material can soften due to the influence of heat, which can reduce the resistance of the polymeric material to the insertion of the fork-shaped prongs of the contacting element.
- the fork-shaped prongs of the contacting element can have knife-like cutting edges, which additionally simplify penetration of the contacting element into the polymeric material.
- the contacting element has at least one cylindrical sleeve for receiving a tension member.
- the cylindrical sleeve is inserted in the longitudinal direction into the polymeric material and encloses the tension member over a partial length in the longitudinal direction, the cylindrical sleeve being pressed onto the tension member.
- the drive belt has cylindrical sleeves in the number of tension members present, so that each tension member has a cylindrical sleeve as a contacting element.
- the cylindrical sleeve can be electrically conductively connected to the tension member of the drive belt without the tension member having to be freed from the polymeric material of the drive belt.
- the polymeric material and/or the cylindrical sleeve can be heated.
- the polymeric material may soften under the influence of heat, which may reduce the resistance of the polymeric material to insertion of the cylindrical sleeve.
- the contacting element has at least one dome which is inserted into the tension member in the longitudinal direction.
- the polymeric material of the drive belt and/or the dome can be heated.
- the polymeric material can soften due to the influence of heat, which can reduce the resistance of the polymeric material to expanding the diameter of the tension member when the dome is inserted into the tension member.
- the dome is preferably designed with a tapered outer contour, for example conical, so that the force for inserting the dome into the tension member can be additionally reduced.
- the drive belt has domes in the number of tension members present, so that each tension member has a dome as a contacting element. It turns out to be particularly advantageous that the contact area between the tension member and the dome inserted therein is particularly large in order to form an electrically conductive connection. By inserting the dome into the tension member, all contact of the dome with the electrically insulating polymeric material of the drive belt can be avoided. In other words, the contact resistance between the dome and the tension member can be kept as low as possible, which means that electrical losses when carrying current can also be low.
- the contacting element has at least one clip, which is particularly U-shaped and is inserted into the polymeric material in a vertical direction and surrounds the tension member in a contacting manner.
- the contacting element can be designed as a U-shaped wire.
- the wire can be designed with a U-shaped radius that corresponds to the outer diameter of the tension member.
- the wire can be U shaped with a first wire end and a second wire end in a vertical direction in the polymer Material of the drive belt are introduced so that a tension member is received between the first wire end and the second wire end.
- the wire can pass through the drive belt in a vertical direction so that the first wire end and the second wire end protrude from the drive belt on the opposite side.
- the wire can be heated, for example by applying an electrical voltage, whereby the polymeric material of the drive belt can be softened or melted, whereby the U-shaped part of the wire can be moved with little effort through the polymeric material to the tension cord and an electrically conductive contact can be formed between the wire and the tension cord.
- the penetration point of the wire into the polymeric material of the drive belt can be resealed by heating the wire and the polymeric material surrounding the wire as previously described.
- the tension member can be connected in an electrically conductive manner via the first wire end and the second wire end to other devices for feeding in and/or drawing current.
- the drive belt has clips or wires equal to the number of tension members present, so that each tension member is assigned a clip or a wire as a contacting element.
- Figures 1 a and 1 b show a schematic representation of a drive belt according to the invention in cross section according to a first exemplary embodiment for contacting a first line element.
- Figures 2a, 2b and 2c show a schematic representation of a drive belt according to the invention according to a second exemplary embodiment for contacting a first line element.
- Figures 3a and 3b show a schematic representation of a drive belt according to the invention according to a third exemplary embodiment for contacting a first line element in a side view.
- Figures 4a and 4b show a schematic representation of a drive belt according to the invention in cross section according to a fourth exemplary embodiment for contacting a first line element.
- the above-mentioned figures are described in Cartesian coordinates with a longitudinal direction X, a transverse direction Y oriented perpendicular to the longitudinal direction Y is also referred to as width Y and the vertical direction Z is also referred to as height Z.
- the longitudinal direction X and the transverse direction Y together form the horizontal, X, Y, which can also be referred to as the horizontal plane X, Y.
- the longitudinal direction X, the transverse direction Y and the vertical direction Z can also be collectively referred to as spatial directions X, Y, Z or as Cartesian spatial directions
- Figure 1 a shows a first embodiment of the drive belt 1 according to the invention with a contacting element 12 with six pairs of fork-shaped prongs 14.
- the contacting element 12 is designed to be connected to the tension member 4 in an electrically conductive manner.
- the fork-shaped tines 14 extend in the vertical direction Z and are arranged in the form of six pairs in a transverse direction Y. In other words, the illustrated embodiment has six pairs or twelve fork-shaped tines 14.
- the drive belt 1 shown schematically has six tension members 4, which are embedded in a polymeric material 2, preferably polyurethane.
- the tension members 4 form a first line element 4 for power transmission and have a metallic material.
- the tension members 4 extend in the longitudinal direction X of the drive belt 1 and are arranged at a distance from one another in the transverse direction Y.
- the distance between two fork-shaped tines 14 of a pair in the transverse direction Y corresponds to 80 percent of the diameter of the tension member.
- the pairs of fork-shaped tines 14 are arranged at the distance between the tension members 4. That's how it is for every couple Fork-shaped tines 14 are assigned a feeder 4.
- the tension members 4 are not damaged when the contacting element 12 is inserted into the polymeric material 2 of the drive belt 1.
- the polymeric material 2 of the drive belt 1 and the contacting element 12 are heated by a heat source 5. The heating causes the polymeric material 2 to soften and provides less resistance to penetration of the contacting element 12 into the polymeric material 2, whereby the contacting element 12 can be inserted into the polymeric material 2 in the vertical direction Z with little effort.
- FIG. 1 b shows the drive belt 1 and the contacting element 12 from FIG. 1 a, the contacting element 12 being inserted into the polymeric material 2 of the drive belt 1 and being electrically conductively connected to the tension member 4.
- the pairs of fork-shaped tines 14 each accommodate a tension member 4 between them.
- the contacting element 12 can be electrically conductively connected to the tension members 4 of the drive belt 1 without the tension members 4 having to be freed from the polymeric material 2 of the drive belt 1. Because the distance between the pairs of fork-shaped tines 14 is smaller than the diameter of the tension members 4, the tension members 4 are deformed between the pairs of fork-shaped tines 14, whereby the contact area between the tension member 4 and the pair of fork-shaped tines 14 of the contacting element 12 increases .
- FIG 2a shows a further embodiment of the drive belt 1 according to the invention in the form of a toothed belt in a side view.
- the contacting element 12 is designed as a cylindrical sleeve 16 for receiving a tension member 4.
- the cylindrical sleeve 16 is inserted in the longitudinal direction X into the polymeric material 2 of the drive belt 1 and encloses the tension member 4 over a partial length in the longitudinal direction Sleeve 16 is heated by the heat source 5.
- Figure 2b shows the exemplary embodiment from Figure 2a shown in a cross section. It can be seen that each tension member 4 is assigned a cylindrical sleeve 16 as a contacting element 12.
- Figure 2c shows that the cylindrical sleeves 16 are plastically deformed in the vertical direction Z by the introduction of a force F into the drive belt 1 and are electrically conductively connected to the tension members 4. There is no polymeric material 2 in the contact area between the tension member 4 and the cylindrical sleeve 16.
- FIG 3a shows a further embodiment of the drive belt 1 according to the invention in the form of a toothed belt in a side view, the contacting element 12 being designed as a dome 18.
- the dome 18 is heated by a heat source 5.
- the polymeric material 2 can soften due to the influence of heat, which reduces the resistance of the polymeric material 2 to an expansion of the diameter of the tension member 4 when the dome 18 is inserted into the tension member 4.
- the diameter of the dome 18 expands in a cone shape, so that the force required to insert the dome 18 into the tension member 4 is additionally reduced.

- the tension member 4 has expanded in diameter in the area around the dome 18.
- the cathedral 18 is essentially surrounded by the tension beam. Due to the contact of the dome 18 with the tension member 4, an electrically conductive connection is formed between the dome 18 and the tension member 4.
- FIG. 4a shows a further embodiment of the invention
- the wire 20 is shaped as a U with a first Wire end and a second wire end are inserted in the vertical direction Z into the polymeric material 2 of the drive belt 1, so that a tension member 4 is received between the first wire end and the second wire end.
- the wire 20 passes through the drive belt 1 in the vertical direction Z, so that the first wire end and the second wire end protrude from the drive belt 1 on the opposite side.
- the wire 20 is heated, for example by applying an electrical voltage to the first wire end and the second wire end, whereby the polymeric material 2 of the drive belt 1 softens or melts, whereby the U-shaped part of the wire 20 passes through the polymer with little effort Material 2 is moved through to the tension cord 4.
