Definitions

  • the invention relates to an electric train with the features of the preamble of claim 1.
  • Such a generic electric train is known from EU-PS 0077 890.
  • the armature shaft carries, on its side facing the transmission, a pinion which meshes with a spur toothing which is formed on the drive-side friction clutch element of the overload slip clutch.
  • the friction clutch element on the output side is connected in a rotationally fixed manner to an intermediate shaft which likewise rotatably carries a further gearwheel on which the power is tapped for transmission to the chain sprocket.
  • the two friction clutch members are by disc springs; which are supported on the one hand on the intermediate shaft and on the other hand on the driven friction clutch member, pretensioned in the frictional engagement position, to such an extent that, in the event of excessive torque as a result of an overload on the hoist, the friction clutch members rotate against one another.
  • the holding brake serves at stopped electric motor to prevent the armature shaft from rotating when the load on the hoist is striving to rotate the armature shaft in order to lower the load.
  • the holding brake is designed as a cone brake, the fixed part being anchored in the motor housing and the rotatable part sitting on the armature shaft.
  • the armature which is axially immovably mounted, contains a hollow shaft which rotates with the drive-side friction clutch member is coupled.
  • the friction clutch element on the output side is rigidly connected to an output shaft leading to the transmission and passing through the hollow armature shaft, a spring holding the two friction clutch elements together in the frictionally engaged position.
  • the friction clutch element on the output side carries an axially displaceable brake ring which can be braked against the motor housing with the aid of a brake plate. This plate is biased into the braking position by means of a lever and a spring, and the release takes place with the help of an additional magnet that overcomes the spring force.
  • a disadvantage of this arrangement is the additional magnet needed to release the brake when the hoist is to be raised or lowered.
  • DE-PS 691 893 an electric motor with a sliding anchor is shown, which carries the drive-side friction clutch member in a rotationally fixed manner on its armature shaft.
  • the friction clutch element on the output side is formed by a conical bell which sits on an output shaft which is axially displaceable in the motor housing.
  • This output-side friction clutch member is also the rotatable brake member, which is biased in the idle state by a spring in the direction of the armature and thus in the direction of a braking surface connected to the motor housing.
  • the torque transmission capacity of the slip clutch can be small if the friction clutch element on the drive side is connected directly to the armature shaft, since the smallest torques occur there.
  • the slip clutch can also be dimensioned accordingly small. The same applies analogously to the brake, which can be smaller the more it is geared to the motor.
  • the overall space requirements are particularly small and the manufacture is very simple if the friction clutch member on the output side and the rotatable brake member are integrally connected to one another.
  • the coupling of the brake member to the partial drive train on the output side takes place by means of a gearwheel that is connected to the brake member in a rotationally fixed manner and is connected to this partial drive train in a geared manner.
  • Another option is the drive power to pass through the brake member so that the brake member is in the power flow.
  • an electric chain hoist 1 is shown in a longitudinal slot. It contains an electric motor 2, a reduction spur gear 3, and an overload slip clutch 4, via which the mechanical power is transmitted from the electric motor 2 to the gear 3, and a brake 5.
  • the electric motor 2 has an approximately cup-shaped motor housing 6, which is flanged with its open front to an intermediate housing flange 7 by means of screws 8.
  • a stator winding 9 In the interior closed on all sides there is a stator winding 9 and a cone-shaped armature 12 which is seated in a rotationally fixed manner on an armature shaft 11 and is designed as a short-circuit rotor.
  • the motor housing 6 contains, in its end remote from the intermediate flange housing 7, a stepped bore 14, in which, seen from the outside inwards, are inserted: a shaft seal 14 and a deep groove ball bearing 16 in which, with the interposition of a sliding bush 17, the armature shaft 11 is rotatably and axially displaceably mounted is.
  • a compression spring 19 designed as a helical spring is supported at one end, the other end of which rests on the adjacent end face of the armature 12.
  • the armature shaft 11 is in this way by the compression spring 19 in the direction of Intermediate housing flange 7 too biased.
  • the other end of the armature shaft 11 is mounted in a stepped bore 22 which is formed in a wall 23 of the intermediate housing flange adjacent to the motor housing 6.
  • a shaft seal 24 and a needle bearing 25 are inserted, so that the armature shaft 11 is also axially displaceably and sealed in the intermediate housing flange 7.
  • a shell-shaped housing cover 26 is screwed on in a sealed manner, which together with the intermediate housing flange 7 forms a gear housing in which the spur gear 3 is accommodated.
  • a countershaft 27 and an output shaft 28 are mounted between the housing cover 26 and the intermediate housing flange 7 by means of roller bearings 29, 31 and 32, 33 held in a stationary manner parallel to the armature shaft 11.
  • the countershaft 27 carries a large spur gear 34 and a pinion 35 connected to it in a rotationally fixed manner, which meshes with a spur gear 36 which is non-rotatably wedged on the output shaft 28.
  • the output shaft 28 protrudes with a portion 37 through a bore 38 in the intermediate housing flange 7 below the motor housing 6 and carries a non-rotatably seated thereon Chain nut 39 for a chain, not shown.
  • the mechanical power is transmitted from the armature shaft 11 to the chain sprocket 39 via the slip clutch 4.
  • This slip clutch 4 is arranged together with the braking device 5, as shown in FIG. 2, in a cup-shaped recess 41 which is formed in the housing cover 26 in the direction of the intermediate housing flange 7 in the extension of the armature shaft 11.
  • the cylindrical recess 41 is provided in its recessed bottom wall 42 with a stepped bore 43 which is coaxial with the armature shaft 11 and which forms a seat for a shaft seal 44 arranged therein.
  • a shaft section 45 of the armature shaft 11 extends through this stepped bore 43.
  • a hub 48 is rotatably supported by two bushes 46 and 47 on the shaft section 45, which is smaller in diameter than the armature shaft 11 in the region of the needle bearing 25.
  • the hub 48 passes through the stepped bore 43 and is provided there with a cylindrical outer circumferential surface against which the shaft seal 44 lies sealingly.
  • the end of the hub 48 adjacent to the intermediate housing flange 7 is provided with a pinion toothing 49 and meshes with the large gear 34 of the countershaft 28 End of a recess 51, in which a further shaft seal 52 is inserted, which seals the hub 48 against the armature shaft section 45.
  • a circular disk 53 is rigidly fastened on the hub 48 and is equipped with a frustoconical outer peripheral surface 54 serving as a braking surface and a flat ring surface 55 pointing away from the bottom surface 42. Both surfaces are coaxial with the armature shaft 11, the latter serving as an output-side friction clutch member of the overload slip clutch 4.
  • the other drive-side friction clutch member consists of a circular, flat disk 56 which, opposite the friction surface 55, is mounted on a profile shaft section 57 in a rotationally fixed and axially displaceable manner.
  • the profile shaft section 57 is an integral part of the armature shaft 11 and it adjoins the armature shaft section 45 to the outside, and, as shown, protrudes a little to the outside beyond the friction clutch member 56.
  • On this protruding part are a number of disc springs 58, which are supported by means of a spacer 59, a washer 61 and a pressure screw 62 against the friction clutch member 56.
  • the friction clutch member which sits on the profiled shaft section 57 in a rotationally fixed and axially displaceable manner, is prestressed against the disk 53, which in turn is supported via the hub 48 against a shoulder 63 formed between the armature shaft section 45 and the region of the armature shaft 11 located behind it.
  • the conical brake surface 54 Opposite the conical brake surface 54 is the second brake member in the form of the conical brake ring 64, which is held in place by an insert 65 and by screws 66 in the cylindrical recess 41.
  • the holder 65 is finally closed by a detachable cap 67.
  • the smallest clear width of the conical brake ring 64 is slightly larger than the outer diameter of the flat disk 56 and also the conical braking surface 68 widens in the direction of the floor 42 in accordance with the diameter increase of the disk 53.
  • the electric cable 1 described works as follows: in the de-energized or idle state, the armature 12, together with the armature shaft 11, is pushed to the left by the compression spring 19 with reference to the figures, as a result of which the disk 53 with the conical braking surface 54 is held in the frictionally engaged position with the conical braking friction surface 68 . As a result, the countershaft gear 34, which meshes with the pinion 49, is braked and, via the further gear train, the output shaft 37 with the chain sprocket 39 is braked against rotation due to the attached load.
  • the holding force of the braking device 5 results from the material pairing of the brake ring 64 and the disk 53 in combination with the feed force of the compression spring 19.
  • the stator 9 pulls the armature 12 while reducing the air gap 13 against the action of the compression spring 19, as a result of which the armature shaft 11 rigidly connected to the armature 12 is also displaced to the right.
  • the abutting on the friction surface 55 de disk 56 presses the disk 53 to the right, whereby the two braking surfaces 54 and 68 are separated from each other.
  • the braking device 5 is released and no longer acts on the drive train between the armature shaft 11 and the output shaft 37. Since the armature 12 begins to rotate at the same time as a result of the current being switched on the output shaft 37 rotated and the lifting element, not shown, raised or lowered, depending on how the armature 12 runs.
  • the armature continues to rotate the disk 56 connected to it in a rotationally fixed manner, while the driven side of the slip clutch, namely the disk 53, remains stationary.
  • the torque which can be transmitted via the slip clutch 4 can be set in operation by turning the pressure screw 62 to a greater or lesser extent and is independent of the force which the displacement anchor can exert.
  • the armature shaft section 45 rotates within the hub 48 mounted on it, while the two braking surfaces 54 and 68 are held out of engagement by the axial component of the armature cable.
  • the compression spring 19 immediately presses the armature shaft 11 together with the armature 12 to the left until a further displacement movement is blocked by the form-fitting system between the braking surfaces 54 and 68.
  • the disk 53 is pushed forward due to the positive connection of the hub 48 to the ring shoulder 63.
  • the hub 48 also slides accordingly to the left, the pinion toothing 49 on the hub 48 correspondingly through the teeth of the gearwheel 34 slides in the tooth longitudinal direction.
  • the braking device 5 lies in the drive train between the clutch surface 55 and the output shaft 37, the pretension with which the disk 56 is pressed against the friction surface 55 of the disk 53 has no influence on the holding force or the braking torque which is generated by the braking device 5 acts on the output shaft 37 in accordance with the reduction.
