Description

Technical Field

[0001] This invention relates to wire guiding elements, brakes for braking shafts, and brake motors having brakes. Background Technology

[0002] As is well known, ferromagnetic magnets can be used as the coil core of an electromagnet, and the windings of an electromagnet can be wound onto a plastic coil frame. Summary of the Invention

[0003] The object of the present invention is to design wire guiding elements simply and cost-effectively, and to form electromagnetically operable brakes and brake motors having such wire guiding elements in a manner that is simple and cost-effectively manufactured.

[0004] According to the present invention, for wire guiding elements, this objective is achieved by the features given in claim 1, and for brakes and brake motors, this objective is achieved by the features given in claim 15.

[0005] For wire guiding elements, especially for coils having winding bodies and turns, an important feature of the present invention is:

[0006] The wire guiding element is force-locked and held in particular, wherein the wire guiding element is inserted into the radial gap of the winding body and is elastically preloaded and / or force-transmitted and held.

[0007] The wire guiding element has a first notch and a second notch, especially the notch that is open to the outside.

[0008] The first notch is configured to be parallel to the second notch.

[0009] The first notch is deeper and, in particular, longer than the second notch.

[0010] In particular, the width of the first notch is greater than the diameter of the winding wire, but less than twice the diameter of the winding wire, and especially less than 120% of the diameter of the winding wire.

[0011] In particular, the width of the second notch is greater than the diameter of the winding wire, but less than twice the diameter of the winding wire, and especially less than 120% of the diameter of the winding wire.

[0012] In particular, the winding body is the inner pole of the electromagnet, especially the inner pole of the electromagnet of the electromagnetically operable brake, wherein the winding is wound around the winding body.

[0013] The advantage here is that the different depths of the two notches allow for the shortest possible wire path, and the wire is introduced at the beginning of the winding and tangentially exited at the end. This maintains wire tension, ensuring that the wire guide element is pressed radially inward by the winding wire, thus preventing it from detaching from the radial gap.

[0014] In a favorable design, the wire guide element is U-shaped. The advantage here is that a preload is generated by the elastic offset of the two legs of the U-shape relative to each other, which then achieves a force-locked connection with the winding frame, especially the inner poles of the electromagnet or brake.

[0015] In an advantageous design, the wire guide element has a first leg that connects to a second leg of the wire guide element via a yoke region.

[0016] In particular, the notch is parallel to the leg orientation.

[0017] In particular, the wire guide element, together with its legs and yoke area, is integrally, especially in one piece, and / or is injection molded. The advantage here is that the wire guide element can be manufactured simply and cost-effectively, and can be easily and reliably fixed in the radial gap, and enables tangential introduction and tangential exit of the winding wire.

[0018] In advantageous designs, contact pins and / or material connections to contact pins are embedded in the yoke region of the wire guide element.

[0019] In particular, the wire guide element is integrally, especially as a single piece, and / or as an injection-molded part. An advantage here is that the wire guide element also additionally functions to retain a contact pin for connection or electrical connection with the winding.

[0020] In a favorable design, a first flange, particularly a protrusion, and a second flange, particularly a protrusion, are formed at the wire guide element to axially define it.

[0021] In particular, the first flange extends uninterruptedly from the first leg through the yoke region to the second leg.

[0022] In particular, the second flange is interrupted by the yoke region and extends on the first leg and on the second leg.

[0023] In particular, the corresponding flange is configured to widen the leg width of the corresponding leg. The advantage here is that the two flanges define the wire guiding element in one direction.

[0024] A key feature of brakes, especially those used for braking motors and for braking shafts, is that the brake has a magnet and an energized winding; the magnet has internal poles.

[0025] In particular, the inner poles are made of ferromagnetic material.

[0026] In this process, the windings—especially the direct windings—are wound around the inner poles.

[0027] The inner electrode has a first flange that protrudes radially at the inner electrode.

[0028] The first flange of the inner pole has a notch, particularly a radial gap, that opens outward, especially toward the outer side of the inner pole and / or radially outward, wherein the radial range covered by the notch overlaps with the radial range covered by the winding.

[0029] The aforementioned wire guide element is inserted into the notch.

[0030] In particular, the winding axis of the winding is oriented coaxially with the axis of the hollow cylindrical outer pole, and / or coaxially with the axis of rotation of the shaft.

[0031] The advantage here is that the wire guiding element can be inserted into the radial gap from the radial outside and is elastically compressed upon insertion, thereby force-locking the wire guiding element and guiding the wire introduced into and drawn out of the winding. For this purpose, the first notch is implemented to be deeper and, in particular, longer than the second notch, so that the introduced wire is guided radially deeper and, in particular, longer than the drawn-out wire. The two notches are parallel and separated only by a middle leg. Here, the middle leg is parallel to the first and second legs.

[0032] The width of the radial slot is slightly smaller than the extension dimension of the wire guide element measured in the tangential or circumferential direction.

[0033] In a favorable design, the magnet has an outer pole.

[0034] In particular, the outer pole is made of a ferromagnetic material.

[0035] The outer electrode is constructed in a hollow columnar shape, and / or the outer electrode is fitted onto the inner electrode, particularly in a manner with gaps.

[0036] The advantage here is that the coil frame does not need to be made of plastic because the inner pole itself provides the necessary winding space, so the winding is directly wound onto the inner pole. The inner pole has two flanges for axially defining the winding space, while in the radial direction, the winding space is defined radially inward by the inner pole and radially outward by the outer pole. The outer pole is fitted onto the inner pole in the axial direction and is axially limited by a second flange of the inner pole, wherein a shoulder is formed at the second flange, which centers the outer pole relative to the inner pole, in particular aligning the cylindrical axis of the outer pole with the winding axis and / or the axial direction of the winding, i.e., the direction of the axis of rotation of the shaft.

[0037] Although a radial gap is permissible between the outer pole and the first flange, this gap is insufficient to form an air gap that effectively prevents magnetic field penetration. Therefore, the second flange is implemented in a radially outward tapering manner, whereby this tapering region saturates at low winding currents and essentially functions as an air gap at rated currents. In this way, significant magnetic field penetration is prevented, especially preventing magnetic short circuits between the outer and inner poles.

[0038] In a favorable design, the inner pole is hollow, specifically in which the shaft passes through the inner pole axially. An advantage here is that, on the side of the brake facing away from the motor stator, the fan can be connected to the shaft in a manner that prevents relative rotation, thus further improving brake cooling. Alternatively, however, an angle sensor for detecting the rotational position of the shaft can also be arranged on the side of the inner pole facing away from the motor stator.

[0039] In a favorable design, the inner electrode has an electrically insulating layer, particularly in the region axially arranged between the first and second flanges.

[0040] In particular, the electrical insulation layer is either a varnish layer or a plastic encapsulation. The advantage here is higher insulation strength. Therefore, the self-insulated winding wires of the winding, especially the self-adhesive wires, are separated from the metal inner pole by another layer. This improves insulation strength. This layer specifically defines the winding, i.e., the insulation layer is arranged at least on the outer surface of the inner pole in the surface area arranged axially between the two flanges, on the side of the first flange facing the second flange, and on the side of the second flange facing the first flange. This layer can be easily and quickly made into a varnish layer. However, alternatively, a more expensive encapsulation can be made using plastic.

[0041] In advantageous designs, through holes and non-through holes, especially blind holes, are formed along the axial direction in the outer pole. The advantage here is that the spring element can be received into the blind hole, thus providing guidance for linear motion.

[0042] In a favorable design, the inner pole, apart from the hole and at least one notch, especially a radial slit, is primarily a body of revolution / rotationally symmetric body, the axis of symmetry of which is coaxially oriented with the axis of the hollow cylindrical inner pole.

[0043] In particular, the radial range covered by the notch overlaps with the radial range covered by the winding. The advantage here is that simple machining can be performed, and the electrical connection lines of the winding can pass through this radial gap.

[0044] In a favorable design, the inner electrode has: a first flange projecting radially onto the inner electrode; and a second flange spaced axially from the first flange, also projecting radially onto the inner electrode.

[0045] In particular, the inner electrode is integrally formed with the first and second flanges, especially as a single piece. The advantage here is that the winding space is defined axially by the two flanges, and potentially hazardous wiring is kept within the winding space. Furthermore, the inner and outer electrodes can be manufactured simply and cost-effectively, especially as machined parts.

[0046] In an advantageous design, the outer diameter of the second flange is larger than that of the first flange. This allows the hollow, cylindrical outer pole to be fitted onto the first flange during manufacturing, thereby abutting against the second flange, which thus serves as both a mating surface and an axial retainer. Furthermore, a threaded element passes through the second flange and the outer pole, allowing the outer pole to be connected to the second flange via the threaded element and a nut screwed onto it. The outer pole surrounds the first flange in a manner that forms a housing. Since the radially outer end region of the first flange is radially tapered outwards and therefore easily broken, this end region is arranged to be protected by the outer pole.

[0047] In a favorable design, the outer pole radially surrounds the first flange.

[0048] In particular, the radial region covered by the first flange is arranged radially inside the radial region covered by the outer pole.

[0049] The area covered by the outer pole along the axial direction includes the area covered by the first flange along the axial direction, or overlaps with the area covered by the first flange along the axial direction. The advantage here is that the outer pole protectively surrounds the first flange, along with the winding space, in a manner that forms a shell.

[0050] In a favorable design, the area covered by the outer pole along the axial direction is adjacent to, and in particular directly adjacent to, the area covered by the second flange along the axial direction.

[0051] Therefore, the outer electrode is particularly abutted against the second flange. An advantage here is that the outer electrode is spatially oriented relative to a flat surface section of the second flange, which in particular has a unique axial position.

[0052] In a favorable design, the inner electrode is made of a first material, and the outer electrode is made of a second material.

[0053] The first material has a lower saturation magnetic flux density than the second material. An advantage here is that two different materials can be used, thus allowing for optimization of material selection based on magnetic flux density and load force. Specifically, the force that loads the inner pole is transmitted to the inner pole via a spring, while the outer pole only conducts magnetic flux density and is not affected by such load forces.

[0054] In a favorable design, the primary material is gray cast iron and / or GGG cast iron and / or ferritic ductile iron, and the secondary material is steel. The advantage here is that simple and cost-effective manufacturing is achievable. In particular, the outer pole can be made into a simple machined part, and the inner pole can be made into a casting.

[0055] In an advantageous design, the wall thickness of the first flange, measured axially, decreases monotonically with increasing radial distance, particularly in the radially outer end region of the first flange, where it decreases strictly monotonically. This has the advantage that this end region saturates even at low magnetic flux levels, thus serving as an air gap for fluxes exceeding this low flux range. This prevents or at least minimizes magnetic short circuits between the first flange and the outer pole.

[0056] In an advantageous design, the first flange has a tapered surface section in the radially outer end region. The advantage here is that it enables simple manufacturing, particularly by allocating a flat surface section of the first flange with only a single axial position to the tapered surface section.

[0057] In a favorable design, a spring is received in a non-through hole on the outer pole, and this spring presses against the armature disc of the brake. The advantage here is that the spring can be easily guided and received.

[0058] In a favorable design, a through hole is formed axially in the second flange for a threaded element to pass through, the threaded element passing through the axial through hole of the outer pole.

[0059] In particular, it passes through the gap in the armature plate. This is advantageous.

[0060] In an advantageous design, the armature disk is connected to the magnet, particularly to the inner and / or outer poles, in a manner that prevents relative rotation, and is arranged to move axially. The advantage here is that friction can be introduced into the armature disk and then transmitted to the stationary components of the brake.

[0061] In a favorable design, the disc-shaped brake block carrier is connected to the shaft in a manner that prevents relative rotation, and is arranged to move along the axial direction.

[0062] In particular, the annular drive component is fitted onto the shaft and connected to the shaft in a manner that prevents relative rotation, especially through keying or press-fitting.

[0063] The driving component has an external toothed portion, and the internal toothed portion of the brake block carrier is fitted onto the external toothed portion. In particular, the brake block carrier and the driving component are connected in a manner that prevents relative rotation, and are arranged to be movable in the axial direction.

[0064] The armature disk is arranged axially between the magnet and the brake block carrier, and the brake block carrier is arranged axially between the components of the armature disk that have a braking surface.

[0065] In particular, the brake block carrier has brake blocks on both sides along the axial direction. This has the advantage of enabling cost-effective manufacturing of the brake. Furthermore, when the winding is not energized, the armature disc is pressed against the brake block carrier by a spring, causing the brake block carrier to press against the brake surface on its side away from the armature disc, thus automatically engaging the brake.

[0066] Optionally, the brake block carrier can also be implemented integrally with the brake block, i.e., as a single piece.

[0067] In this paper, the external toothed portion always includes an external polygonal structure, especially a hexagonal structure; in this paper, the internal toothed portion always includes an internal polygonal structure.

[0068] A key characteristic of brake motors is that they consist of a motor and a brake, with the shaft being the motor's rotor shaft.

[0069] In particular, the component is designed as a bearing cover or friction plate.

[0070] In particular, the component is connected to the magnet in a manner that prevents relative rotation.

[0071] The advantage here is that the brake motor can be manufactured simply and cost-effectively, for which the windings can be directly wound onto the inner poles, thus enabling the brake and therefore the brake motor to be implemented with the smallest possible structural volume and / or compactness. The outer poles, which can be made of steel, can be manufactured simply and cost-effectively by turning.

[0072] Further advantages are provided by the dependent claims. The invention is not limited to the combination of features of the claims. For those skilled in the art, particularly for purposes proposed and / or proposed by comparison with the prior art, other reasonable combinations of features of the claims and / or individual claims and / or description features and / or drawings are possible.

[0081] exist Figure 8 The wire guide element 50 is shown in a side view. Detailed Implementation

[0082] As shown in the figure, the magnet has an annular outer pole 2, which is pushed onto the inner pole 1 of the magnet.

[0083] Therefore, the magnet is implemented in two parts and different materials can be used.

[0084] In particular, the following material is used as the material of the outer pole 2, and the saturation magnetic flux density of the material is higher than that of the material of the inner pole 1.

[0085] Preferably, steel is used as the material for the outer electrode 2, and gray cast iron and / or GGG cast iron, especially ferritic ductile iron, is used as the material for the inner electrode 1. Therefore, machining can be easily performed.

[0086] The outer pole 2 is designed as a hollow column, wherein axial through holes and axial non-through holes, especially axial holes, are formed at intervals along the circumferential direction. A spring 3 is inserted into the axial non-through hole, i.e., blind hole, which is supported at the outer pole 2 and pressed against the armature disc 43 of the brake.

[0087] A bolt 4 passes through the axial through hole of the outer pole 2 and also through the notch of the armature disk 43, thereby allowing the armature disk 43 to be arranged axially movable and in a manner that prevents it from rotating relative to the outer pole 2. Alternatively or additionally, a guide pin may be provided, which passes through the notch of the armature disk 43 and is fixed to the outer pole 2.

[0088] An annular drive member 41 is fitted onto the shaft to be braked, particularly the rotor shaft. The drive member has external teeth and is connected to the shaft in a manner that prevents relative rotation, particularly by means of a key connection.

[0089] The disc-shaped brake block carrier 42 has its inner teeth fitted onto its outer teeth, wherein the inner teeth mesh with the outer teeth. Therefore, the brake block carrier 42 and the drive member 41 are connected in a manner that prevents relative rotation, but they can move in the axial direction.

[0090] A braking surface 40 is constructed on the side of the brake block carrier 42 that is axially opposite to the armature disk 43, particularly on the friction plate received in the housing 44 or at the bearing cover of the motor, which receives the bearing of the motor rotor shaft.

[0091] The armature disc 43 is arranged axially between the brake block carrier 42 and the outer pole 2. The brake block carrier 42 is arranged axially between the armature disc 43 and the brake surface.

[0092] An energized winding 5, especially a coil winding, is wound on the inner pole 1. When the winding is energized, the armature disk 43 overcomes the elastic force generated by the spring 3 and is attracted toward the magnet, especially toward the outer pole 2, thereby allowing the brake block carrier to get away from the brake surface.

[0093] When the winding 5 is not energized, the spring 3 presses the armature disc 43 against the brake block carrier 42, thus pressing the brake block carrier against the brake surface located on the side opposite to the armature disc 43. Therefore, frictional locking occurs axially on both sides of the brake block carrier 42, particularly frictional locking with the brake surface on one side and frictional locking with the armature disc 43 on the other side.

[0094] Preferably, the winding 5 is directly wound onto the inner pole 1, thus eliminating the need for a plastic component in the middle, and especially eliminating the need for a coil frame.

[0095] The inner pole 1 has: a first flange 31 projecting radially, which defines the winding 5 in the axial direction; and a second flange 32 projecting radially, which defines the winding in the opposite direction to the axial direction. The second flange 32 preferably projects further than the first flange 31, such that the hollow cylindrical outer pole 2 abuts against the axial end face of the second flange 32, and the first flange 31 is arranged radially inside the outer pole 2.

[0096] The area covered by the outer pole 2 in the axial direction includes the area covered by the first flange 31 in the axial direction, and in particular, it also includes the area covered by the winding in the axial direction.

[0097] The first flange 31 has a flat axial end face, which serves as the pole face 33.

[0098] The first flange 31 is tapered at its radially outer end region, such that the axial wall thickness of the first flange 31 decreases monotonically with increasing radial distance, and in particular, decreases strictly monotonically.

[0099] Therefore, the first flange 31 has a bevel 6, particularly a tapered surface, in the radial end region. Due to this tapered shape, the tapered region can achieve magnetic saturation even when a small current flows through the winding, and thus mainly serves as an air gap between the outer pole 2 and the inner pole 1. Nevertheless, axially defining the winding 5 is still achieved.

[0100] Here, the radial direction and radial spacing are always referenced to the axis of rotation of the shaft. The axial direction is parallel to the axis of rotation of the shaft, and the circumferential direction is referenced to the axis of rotation of the shaft. The winding axis of winding 5 is coaxial with the axis of rotation of the winding.

[0101] The area covered by the second flange 32 along the axial direction is adjacent to the area covered by the outer pole 2 along the axial direction.

[0102] The inner pole 1 and the outer pole 2 are made of ferromagnetic materials.

[0103] The bolt 4 passes through a notch arranged radially outside the first flange in the second flange and is aligned accordingly with a corresponding notch in the outer pole 2, and the bolt 4 also passes through the corresponding notch in the outer pole.

[0104] The notch 30 is formed in the second flange 32 as a radial gap, particularly a notch or radial recess, so that the connecting lines of the winding 5 can pass through. The radial range covered by the radial gap overlaps with the radial range covered by the winding 5 in the radial direction.

[0105] Except for the notch and notch 30 through which bolt 4 passes, the inner pole 1 is implemented as a rotating body.

[0106] In order to allow the shaft to be braked, especially the rotor shaft of a brake motor with a brake, to pass through the brake axially, the inner pole 1 is hollow. Therefore, the brake can be mounted on the motor of the brake motor, and an angle sensor for detecting the rotational position of the shaft and / or a fan can be arranged on the side of the brake axially away from the motor stator.

[0107] The pole face 30 is designed to be flush with the outer pole 2 along the axial direction, and in particular, the axial position of the pole face 30—especially in the axial direction—defines the area covered by the outer pole 2 along the axial direction.

[0108] like Figures 5 to 8 As shown, the wire guide element 50 is inserted into the notch 30, particularly into the radial slit.

[0109] The wire guide element 50 is U-shaped and has an additional intermediate leg. The first leg 61 and the second leg 60 of the wire guide element 50 are connected by the yoke region 64 of the wire guide element 50.

[0110] The two legs 60 and 61 have corresponding guide ramps on their outer sides. When the wire guide element 50 is inserted, the guide ramps are respectively attached to the notch 30, especially the edge of the radial gap. As the width of the guide ramps increases, the legs 60 and 61 are elastically offset, so that the wire guide element 50 is clamped in the notch 30, especially the radial gap.

[0111] A first notch 71, in particular a cut or a radially oriented first recess, and a second notch 70, in particular a cut or a radially oriented second recess, are formed in the yoke region 64 parallel to the legs 60, 61. The first and second notches are implemented parallel to each other and also parallel to the two legs 60, 61.

[0112] Therefore, the notches 70 and 71 are generally radially oriented, however, these notches have different radial depths. The two notches 70 and 71 open radially outward and have different minimum radial distances from the axis of rotation of the shaft. Thus, these notches cut into the yoke region with different radial depths, thereby forming the intermediate leg.

[0113] In this way, when winding the coil winding 5, the winding wire can first be guided through the first notch 71 into the winding space arranged between the two flanges 31, 32, and after winding the coil winding 5, it can be led out from the winding space through the second notch 70.

[0114] Metal contact elements 80, particularly contact pins, are embedded in the wire guide element 50. The ends of the winding wire are fixed to these contact elements to achieve contact with the electrical conductors. The corresponding stripped electrical conductors and the corresponding ends of the winding wires are electrically connected to the corresponding contact elements 80, particularly the contact pins.

[0115] The wire guide element 50 has a first flange 62, particularly a protrusion, at its axial rear edge region, which serves as an axial limiting member for the wire guide element 50. Here, the first flange 62 extends along the legs 60, 61 and along the yoke region 64. The first flange 62 extends uninterruptedly from the first leg 61 through the yoke region 64 to the second leg 60, and protrudes tangentially at the first leg 61 and in the opposite direction at the second leg 60.

[0116] The wire guide element 50 has a second flange 63, particularly a protrusion, at its axial leading edge region. This second flange serves, in particular, as an axial limiting member for the reverse direction of the wire guide element 50. Here, the second flange 63 extends along the legs 60, 61, but not along the yoke region 64. The second flange 63 is implemented intermittently and protrudes tangentially on the first leg 61 and in the opposite direction on the second leg 60.

[0117] Therefore, the wire guide element 50 is defined in two directions along the axial direction by two flanges 62 and 63.

[0118] In particular, the width of the first notch 71 is greater than the diameter of the winding wire, but less than 120% of the diameter of the winding wire. In particular, the width of the second notch 70 is also greater than the diameter of the winding wire, but less than 120% of the diameter of the winding wire.

[0119] Preferably, the wire guiding element 50 is made of plastic injection molded part.

[0120] In another embodiment of the invention, the pole face 30 protrudes axially, such that the area covered by the first flange 31 in the axial direction overlaps with the area covered by the outer pole 2 in the axial direction.

[0121] In another embodiment of the invention, the inner electrode 1 has an electrically insulating layer to improve insulation strength. The electrically insulating layer may be a varnish layer or a plastic encapsulation portion. Preferably, the contact surface facing the outer electrode 2 is configured to have no insulating layer.
