Definitions

  • the present invention relates to an electromotive adjusting device, for instance, for doors, shutting flaps and for any other mechanism to be adjusted, whereby the rotary movement of the rotor is transformed into an axial reciprocating movement of an operating rod and furthermore, wherein this device is equipped with a magnet brake, as well as with means fora return of the operating rod into a safety position upon discontinuance of feeding of energy.
  • a weataher door in a mine must be capable of performing an automatic opening or also closing, if the mine ventilator becomes inoperative, or a brake must be applied, if the driving energy for a machine ceases, or even the doors of a bank should close automatically, if electric current feed discontinues.
  • the rotary locking of the ball-thread spindle can be brought about, for instance, in such manner that the opposite end of the spindle is formed with a polygon crosssection and is mounted in a corresponding guide of a motor housing extension formed'as a protecting cap, or
  • a danger occurs, that means, if the current fails, for instance, at the moment, in which the operating rod just opens the flap at the exit of a bunker, then, on the one hand, the motor loses its current and, on the other hand, the magnet brake opens up, so that in the present instance, return means formed as springs can be rendered effective, and move back the operating rod in axial direction, until the safety condition, that means, the original position, is assumed, and thus, the flap is closed again.
  • the friction of the ball-thread is so low thereby, that a return setting is possible without any diificulties.
  • the present invention provides, by using structurally simple means, a particw larly advantageous and economic adjusting apparatus, which even in the case of danger, for instance, in case of loss of current feed, is in position to return automatically to its original position, whereby the requirements of the practice are taken in account to the full extent.
  • the adjusting device comprises a housing 1, in which an electric motor with a stator winding 2 and a stator 3 is disposed, which electric motor starts rotation of the rotor 4 upon connection with the current source.
  • the motor can be a three phase current motor, an alternating current motor, an A.C./D.C.motor or a direct-current motor, for which reason, also for the different structural possibilities the brushes 5 and the collector 6 areshown. These parts can be omitted in case of a three-phase motor.
  • the rotor 4 has longitudinal bores distributed about its periphery, through which two flanged hollow shaft sections 8 and 9 are rigidly and concentrically connected by means of screw-bolts 7.
  • the sections 8 and 9 serve also the purpose of centering the inside of the shortcircuiting ring It worked to exact measurements and disposed on both sides of the rotor 4.
  • the hollow shaft section 8 includes a ball-thread, which has an appreciably smaller friction compared with a normalthread, because the threads are replaced by balls 11 rolling during the relative movement of the nut and the thread.
  • the threads of the operating rod 12 having circular crosssection form the other part of the ballthread, which operating rod 12 has a forked head 13 at its upper end. As much as this connection does not permit a rotation of the operating rod 12, the latter will reciprocate axially in either direction upon switching on the motor in dependency upon its direction of rotation.
  • the operating rod 12 be equipped with a longitudinal groove (not shown) over a wedge guide, which is arranged, for instance, in the washer member 14, and which prevents the rotation and, thereby, brings about the reciprocating movement of the operating rod 12. It is also possible to form the lower end of the operating rod 12 in the housing or protecting cap 15 with a square cross-section, and to arrange a corresponding guide in the housing 15, in order to bring about the same effect, whereby it has been found of advantage, that the outwardly projecting operating rod 12, due to the elimination of the longitudinal groove, can be more easily sealed relative to the housing 1 at the point of the washer member 14, in order to prevent the penetration of dirt into the housing 1.
  • the operating rod 12 is guided only in the ball-thread and can freely reciprocate otherwise, if the guiding by a guide wedge, or by a square cross-section of one end, is neglected, which operating rod 12, however, may be also designed for easy operation.
  • the hollow shaft section 9, having a radially extending flange 13 serves as a brake-disk of a magnet brake.
  • the magnet brake comprises, as is known, a field coil 17 disposed in an iron ring 18, which is rigidly secured in the motor housing 1.
  • the iron ring 18 receives inside thereof a roller bearing 19, in the same manner as on the opposite side a housing part or an annular member 20 connected with the housing 1 receives the roller bearing 21.
  • These two roller bearings 19 and 21 thus constitute the actual mounting of the motor.
  • the two thrust bearings 22 and 23 serve the purpose of absorbing the sliding pressure 'of the operating rod 12 upon the housing 1 and finally, its displacement (not shown).
  • annular disks 24 and 25 are disposed on the front and back side, respectively, of the annular magnet 18 with its field coil 1'7, which annular disks 24 and 25 are connected by means of bolts 26 distributed equally about the periphery.
  • a pressure spring 27 is arranged on each of the bolts 26, which pressure spring 27, supporting itself in its inoperative position on the bottom of the iron ring 18, retains the two connected annular disks 24 and 25 in the position shown in the drawing.
  • the brake, formed of the parts 16 and the annular disk 24 with the two brake coverings 28, is thus open or in its inoperative position.
  • the part 16 can rotate freely and the operating rod 12 moves in one direction depending upon the direction of rotation as long, till the collar cam 29 either engages the contact 30 or the contact 31, both of the cont-acts 30 and 31 being likewise disposed in the housing part 15, which contacts 30 or 31 interrupt the feeding of current to the motor through the circuit breaker of the motor.
  • the annular field coil 71 is connected with the phase voltage of the motor by means of the closing contacts of the circuit breaker With the help of a rectifier.
  • the magnet pulls the disk 25 at its front side and brings into engagement, thereby, the brake coverings 28, so that the operating rod 12 is likewise secured in its position by means of the retained rotor and the ball-thread.
  • a very suitable and useable application range for this embodiment is found, for instance, in the automatic operation of the hand brake of automotive vehicles. It is possible, without any particular additional circuits, to connect the motor of the device, designed in accordance with the present invention, to the battery of the vehicle by means of the ignition key, such that upon switched-on ignition, the hand brake is released. In this case, the motor has been put to rotation by the battery voltage, until it is switched off by the terminal contacts and the magnet brake is switched on at the same moment, which retains the operating rod 12 in the opening position for the hand brake.
  • An electromotive adjusting device comprising a housing
  • an electric motor including a rotor
  • a magnet brake disposed axially spaced apart from said rotor
  • At least one hollow shaft section having a flange disposed axially adjacent said rotor and mounted in said housing,
  • said hollow shaft section including along a part of its axial length a nut complementary to said ball receiving thread of said operating rod and receiving balls, said nut supporting said operating rod,
  • said one of said hollow shaft sections having a radially disposed flange carrying a layer of braking material on one of its faces
  • said electro-Inagnetic brake including a brake ring carrying a layer of braking material opposite said layer of said flange,
  • said brake ring cooperating with said flange and thus stopping the rotation of said one of said hollow shaft sections and, thereby, of said rotor.
  • the device as set forth in claim 1, which includes a protecting cap extending from one end of said operating rod extending beyond said housing into said protecting cap.
  • the device as set forth in claim 3, which includes a longitudinal potentiometer disposed in said protecting cap adjacent the end of said operating rod, and
  • the device as set forth in claim 3, which includes tension and pressure springs, respectively, disposed within said protecting cap and affecting the end of said operating rod guided in said protecting cap, and
  • tension and pressure springs causing a reciproeating movement of said operating rod into its original position during non-operativeness of said magnet brake and during non-feeding of said electric motor.
  • said springs comprise a first spring engaging said housing at one of its ends and said collar at the other of its ends, and
