Definitions

  • the invention relates to a gear arrangement for the synchronized driving of an electrical switching contact and a signaling switch.
  • the patent specification DE 102 05 334 C1 an electrical switching arrangement with a first switching contact and a second switching contact can be removed.
  • the two switching contacts are each arranged to be linearly displaceable, with a movement being coupled to the two switching contacts via a rotatable connecting link.
  • the disclosure document DE 10 2013 213 303 A1 an electrical switch can be removed. On the electrical switch, a rotary movement is converted into an oscillating movement of a switch component.
  • a swivel arm is arranged on a motor shaft, which drives a carriage via a contact roller.
  • DE 10 2006 031 220 A1 discloses a gear arrangement for driving at least one electrical switching contact.
  • the transmission arrangement has a link arrangement which is connected to a link scanning element and can be moved relative to the link scanning element and has a link gear.
  • the link arrangement has at least a first and a second sub-element, which in each case partially define the link path that can be picked up by the link scanning element.
  • the object of the invention is to improve the drive and the signaling of the switching state of an electrical switching contact.
  • the transmission shaft is rotatable about a longitudinal axis of the transmission shaft by a motor.
  • the gate is rigidly connected to the transmission shaft and has a link gear with two end areas and a central area running between the end areas.
  • the sliding element can be moved linearly.
  • a sliding block guided through the link passage is arranged on the thrust element.
  • the eccentric is rigidly connected to the transmission shaft and has an eccentric nose through which the carriage can be linearly displaced between two end positions.
  • the link gear and the coupling of the eccentric lug to the carriage are designed in such a way that rotation of the transmission shaft causes displacements of the pusher element and the carriage when the sliding block has a position in the middle region of the link gear, and causes no displacements of the pusher element and the carriage when the sliding block has a position in an end area of the link passage.
  • the gear arrangement enables synchronized displacements of the carriage and the pusher element. Since the carriage can be coupled to the switching contact and the sliding element can be coupled to the signaling switch, the signaling switch can be informed of the current switching state of the switching contact via the sliding element be signalled.
  • the switching status can be output by the signaling switch, for example, to a field control device that switches a motor voltage of the motor so that the motor can be switched off when the switching contact has reached a defined switching status. This enables motor control without additional contactors directly based on the signal output by the signaling switch.
  • the motor can coast down without causing further movements of the carriage and the pushing element, since the sliding block has then reached an end area, so that further rotation of the transmission shaft does not cause any displacements of the pushing element and the carriage.
  • the motor coasts down and is stopped by its inertia alone, without the need for a mechanical or electrical motor brake to stop the motor, a complex gearbox or a special freewheel for the motor.
  • This reduces the costs of the gear arrangement compared to gear arrangements with such additional functions and simplifies and shortens the assembly of the gear arrangement, since no adjustment work is required for switching off the motor.
  • no direct current motor is required to brake the motor, so that the gear arrangement can also be used alone with an alternating current motor, as a result of which the gear arrangement can be used in a variety of ways.
  • each end area of the link gear runs along a circular path section of a circular path around the longitudinal axis of the transmission shaft. This prevents the sliding element from being displaced by rotations of the transmission shaft in a structurally simple manner when the sliding block is in a position in an end region of the sliding link gear.
  • the pusher element has a pusher element toothed rack for coupling to the signaling switch.
  • the pusher element can be coupled via the pusher element toothed rack to a signaling switch in particular, which has a signaling switch shaft with an in the push element rack has engaging signaling switch gear.
  • the transmission arrangement has an output shaft which can be coupled to the switching contact and on which an output shaft gear wheel is arranged, and a carriage rack which is arranged on the carriage and with which the output shaft gear wheel engages.
  • the transmission arrangement has a transmission spur gear rigidly connected to the transmission shaft for coupling the transmission shaft to the motor.
  • the transmission shaft can be driven by the motor via the transmission spur gear, for example by means of a motor spur gear that can be driven by the motor and interacts with the transmission spur gear.
  • the carriage has a carriage recess which is delimited by a recess edge against which the eccentric lug rests for moving the carriage and from which the eccentric lug is decoupled when the sliding block is in a position in an end region of the link path. This prevents the carriage from being displaced by rotations of the transmission shaft in a structurally simple manner when the sliding block is in a position in an end region of the sliding link gear.
  • the gate and the transmission shaft can be rigidly connected to one another in two different relative positions, with one side of the gate facing a different end of the transmission shaft in a first relative position than in the second relative position.
  • the gear assembly can be rebuilt, with the backdrop relative to the Transmission shaft is turned.
  • the gear arrangement can advantageously be adapted to a displacement direction which is dependent on the design of the signaling switch and in which the sliding element must be displaced in order to move the signaling switch from an on state to an off state, for example.
  • a reversal of the sense of direction of the movement of the transmission shaft or of the carriage or of the output shaft can be provided.
  • the assignment of its switching times relative to the transmission shaft or the carriage or the output shaft can be adjusted while retaining the signaling switch by controlling it.
  • the pusher element is preferably in the same position in both relative positions of the connecting link and the transmission shaft when the sliding block strikes the same end of the link path. This means that the thrust element can be displaced in the same way in both relative positions of the connecting link and the transmission shaft, with only the direction of rotation of the transmission shaft differing in the two relative positions for displacing the thrust element in a defined direction.
  • a switching device has an electrical switching contact, a motor, a signaling switch and a gear arrangement according to the invention, the transmission shaft of the gear arrangement being rotatable by the motor about the longitudinal axis of the transmission shaft, the carriage of the gear arrangement being coupled to the switching contact and the pushing element of the gear arrangement being connected is linked to the signaling switch.
  • the thrust element of the gear arrangement has a thrust element rack and the signaling switch has a signaling switch shaft on which a signaling switch gear wheel that engages in the thrust element rack is arranged.
  • the link gear of the gear arrangement can be designed in such a way that the amount of a rotation angle of a rotation of the transmission shaft, in which the sliding block crosses the central area of the link gear, corresponds to the amount of a rotation angle by which the signaling switch shaft is rotated during this rotation of the transmission shaft.
  • the link gear of the gear arrangement can be designed in such a way that the amount of a rotation angle of a rotation of the transmission shaft, in which the sliding block crosses the middle area of the link gear, differs from the amount of a rotation angle by which the signaling switch shaft is rotated during this rotation of the transmission shaft.
  • the transmission arrangement has an output shaft coupled to the switching contact, on which an output shaft gear wheel is arranged, and on the carriage of the transmission arrangement a carriage rack is arranged, in which the output shaft gear wheel engages.
  • a spur gear is arranged on the transmission shaft and the motor is coupled to the transmission shaft via the spur gear and a spur motor which can be driven by the motor and interacts with the spur gear.
  • the only figure shows a perspective representation of a gear arrangement 1 for the synchronized driving of an electrical switching contact (not shown) and a signaling switch 3.
  • the transmission arrangement 1 comprises a transmission shaft 5, an eccentric 7, a connecting link 9, a thrust element 11, a carriage 13, a transmission spur gear 15 and an output shaft 17.
  • the eccentric 7, the setting 9 and the transmission spur gear 15 are rigidly connected to the transmission shaft 5.
  • the transmission shaft 5 can be rotated about a longitudinal axis 19 of the transmission shaft 5 by a motor via the transmission spur gear 15 and a motor spur gear that can be driven by the motor and interacts with the transmission spur gear 15 .
  • the motor and the motor spur gear are not shown in the figure.
  • the gate 9 has a link gear 21 with two end areas 22, 23 and a central area 25 running between the end areas 22, 23.
  • Each end region 22, 23 runs along a circular path section of a circular path around the longitudinal axis 19 of the transmission shaft 5, the two circular paths running in a plane orthogonal to the longitudinal axis 19 and the circular path of a first end region 22 at a smaller distance from the longitudinal axis 19 than the circular path of the second End portion 23 has.
  • a sliding block 27 which is guided through the link passage 21 , is arranged on the sliding element 11 .
  • the thrust element 11 is linearly displaced when the transmission shaft 5 rotates about the longitudinal axis 19, orthogonally to the longitudinal axis 19, with the direction of this displacement depending on the direction of rotation of the transmission shaft 5. Due to the course of the end regions 22, 23 of the slideway 21 along circular path sections of circular paths about the longitudinal axis 19, a rotation of the transmission shaft 5 about the longitudinal axis 19 does not change the position of the sliding block 27 and therefore also does not cause any displacement of the pushing element 11 when the sliding block 27 moves a Position in one of the two end regions 22, 23 of the link gear 21 has.
  • the sliding element 11 is coupled to the signaling switch 3 .
  • the pusher element 11 has a pusher element rack 29, which runs orthogonally to the longitudinal axis 19 and parallel to a displacement direction of the pusher element 11, and the signaling switch 3 has a signaling switch shaft 31 that is arranged parallel to the transmission shaft 5 and on which a signaling switch gear wheel 33 that engages the pusher element rack 29 is arranged is.
  • This coupling of the sliding element 11 to the signaling switch 3 causes linear displacements of the sliding element 11 to rotate the signaling switch shaft 31.
  • the eccentric 7 has an eccentric nose 35 which, when the transmission shaft 5 rotates about the longitudinal axis 19 , moves on a circular eccentric path which runs about the longitudinal axis 19 in a plane orthogonal to the longitudinal axis 19 .
  • the carriage 13 is guided on two guide rails 37 and can be linearly displaced on the guide rails 37 orthogonally to the longitudinal axis 19 .
  • the carriage 13 is displaced simultaneously with the pusher element 11 by the eccentric nose 35 .
  • the carriage 13 has a carriage recess 39 which is delimited by a recess edge 41 on which the Eccentric nose 35 is applied when the pusher 11 is moved.
  • the carriage recess 39 has a recess opening 43, through which the eccentric lug 35 moves out of the carriage recess 39 when the sliding block 27 is moved from the middle region 25 of the slideway 21 into one of the end regions 22, 23, and through which the eccentric lug 35 moves into the carriage recess 39 moves in when the sliding block 27 is moved from one of the end regions 22, 23 of the sliding link gear 21 into the middle region 25.
  • the carriage recess 39 is designed in such a way that the eccentric lug 35, after moving into the carriage recess 39, contacts the recess edge 41 when the sliding block 27 enters the middle region 25 of the link passage 21 from one of the end areas 22, 23, moves the carriage 13 when the The sliding block 27 then passes through the middle region 25 to the other end region 22, 23 and is decoupled from the recess edge 41 when the sliding block 27 reaches the other end region 22, 23.
  • the sliding block 27 is located in the first end area 22. If the connecting link 9 is rotated counterclockwise from the position shown (according to the perspective shown), the eccentric lug 35 first moves towards the recess opening 43 and then through the recess opening 43 is moved through out of the carriage recess 39 . When the sliding block 27 reaches the central region 25 of the link passage 21, the eccentric nose 35 moves back into the carriage recess 39, contacts the recess edge 41 and displaces the carriage 13 as long as the pushing element 11 is moved. When the sliding block 27 finally reaches the second end area 23, the eccentric lug 35 decouples from the recess edge 41, so that the carriage 13 is no longer displaced. Correspondingly, the carriage 13 is shifted in the other direction when the sliding block 27 runs through the central area 25 starting from the second end area 23 to the first end area 22 of the link path 21 .
  • the movements of the carriage 13 are transmitted to the output shaft 17 .
  • the carriage 13 has a carriage rack 45 which runs orthogonally to the longitudinal axis 19 and parallel to a displacement direction of the carriage 13 .
  • An output shaft gear wheel 47 arranged on the output shaft 17 engages in the carriage rack 45 so that linear movements of the carriage 13 cause rotations of the output shaft 17 .
  • the output shaft 17 is coupled to the switching contact in such a way that rotations of the output shaft 17 in a first direction of rotation open the switching contact and rotations of the output shaft 17 in a second direction of rotation opposite the first direction of rotation close the switching contact, so that each of the two end positions of the carriage 13 corresponds to a switching state of the switch contact.
  • the gear arrangement 1 enables synchronized displacements of the carriage 13 and the pusher element 11, which cause synchronized rotations of the output shaft 17 and the signaling switch shaft 31, so that the two end positions of the signaling switch shaft 31 that correspond to an end position of the carriage 13 signal the switching state of the switching contact.
  • the signaling switch 3 has electrical components, not shown in detail, which are arranged in several switching levels arranged one behind the other along the signaling switch shaft 31 and to which the switching state of the switching contact is transmitted by the position of the signaling switch shaft 31 .
  • the electrical components can be contacted via terminal lugs 49 of the signaling switch 3, which are brought out of a housing of the signaling switch 3.
  • a signal can be output to a field control device by connection lugs 49, which switches a motor voltage of the motor so that the motor is switched off when the carriage 13 has reached an end position.
  • the motor can then run out without causing further movements of the carriage 13 and the pusher element 11, since the eccentric nose 35 is then decoupled from the recess edge 41 and the sliding block 27 has reached an end region 22, 23.
  • the connecting link 9 and the transmission shaft 5 can be rigidly connected to one another in two different relative positions, with one side of the connecting link 9 facing a different end of the transmission shaft 5 in a first relative position than in the second relative position.
  • the thrust element 11 is in the same position in both relative positions of the link 9 and the transmission shaft 5 when the link block 27 strikes the same end of the link passage 21 .
  • the figure shows a first relative position, in which a side of link 9 that is not visible in the figure faces transmission spur gear 15 . In the second relative position, this side of the connecting link 9 faces away from the transmission spur gear 15, that is to say the connecting link 9 is turned relative to the transmission shaft 5 in relation to the first relative position.
  • the central area 25 of the link gear 21 runs in the second relative position below the transmission shaft 5 when the sliding block 27 is in the link gear 21 at the position shown in the figure.
