Definitions

  • the present invention relates to a drive for a working machine, in particular a press drive, according to claim 1, as well as a working machine, in particular a forming press, according to the preamble of claim 15.
  • a drive according to the prior art for a work machine in particular a press drive, essentially comprises an electric motor, a transmission and a brake. Since a flywheel is dispensed with, such a drive is also referred to as a "direct drive”. Drives for working machines that are equipped with a flywheel and / or driven by a belt drive are accordingly not called direct drives.
  • the electric motor including the gear is arranged on one side of the press housing and drives a press shaft.
  • the brake is located on the other side of the press housing and brakes the motor via the press stand as needed.
  • Such an arrangement has disadvantages. It is, for example, an extended press shaft necessary so that the brake can be flanged in a suitable manner. Also, a complete brake unit is necessary, which must be laboriously mounted on the press housing. Furthermore, an additional wiring for controlling the brake is provided, which must be laid according to the side facing away from the electric motor or gear side of the press housing. Furthermore, a protective device for the brake is to be provided.
  • the drive has an electric motor, a transmission and a brake arranged between the transmission and the electric motor.
  • the brake can be integrated into the drive, but at least not more than a separate part on the side opposite the electric motor or transmission side of the press housing must be arranged.
  • the brake housing can be designed much more material-saving, for example, because no completely enclosing brake housing is needed.
  • parts of the transmission or of the transmission housing and / or parts of the electric motor or of the electric motor housing can be used as a brake housing.
  • the drive is equipped with a drive shaft, wherein the drive shaft is provided at least between the electric motor and the transmission, wherein the drive shaft is passed through the brake and can be braked by the brake. It proves to be advantageous that the brake between the gearbox and the electric motor in relation to the gear ratio of the torque can be made smaller than a torque known from the prior art drive. This results in a considerable cost savings.
  • the drive has a housing, wherein the transmission, at least in sections, and the brake are accommodated together in the housing.
  • This compact design contributes to the fact that the drive has only a low weight and also occupies little space, whereby the proposed drive very well on one side of a working machine, in particular a forming press attach.
  • the housing has a transmission housing and a brake housing, wherein the transmission housing is equipped with a Pressengeratiusean gleichflansch and a Bremsengeratiusean gleichflansch, wherein the brake housing is equipped with a Getriebegephaseusean gleichflansch, and with a Elektromotoran gleichflansch.
  • the transmission is a planetary gear.
  • a planetary gear allows the necessary reduction of the rotational movement and takes only a small space.
  • the entire drive can be made very compact and in particular lightweight, which in particular in connection with the attachment of the drive including brake on only one side of the machine, in particular the forming press, is advantageous. For example, little space is given away next to the work machine, and the static weight load is the Working machine at least slightly lower, since the drive can already be made lighter.
  • the drive shaft is equipped with a second gear
  • the drive shaft is equipped with an adapter
  • the adapter is mounted on the hollow shaft, wherein the adapter in particular with a toothing is equipped, which is in engagement with the second gear of the drive shaft.
  • the adapter is a hollow cylinder which encloses at least one section of the drive shaft.
  • Another object of the present invention is to propose a working machine, in particular a forming press, comprising a press housing, a press shaft, as well as a drive for the press shaft, which can be designed more cost-effective and in which a part of the cable material, the Protective devices and the housing, which must be provided in a working machine according to the prior art, can be saved.
  • the drive is a drive according to one of claims 1 to 14. Due to the drive used, it can be dispensed with that a brake must be provided on the side of the press housing or the press shaft opposite the electric motor or the gearbox.
  • a brake must be provided on the side of the press housing or the press shaft opposite the electric motor or the gearbox.
  • part of the attachments such as a separate protection device for the brake.
  • a part of the housing material for the brake can be saved, since parts of the gear housing and the electric motor can be shared as a housing for the brake.
  • Fig. 1 is outlined a press or press drive according to the prior art.
  • the press has a press housing 4, on which both an electric motor 1 together with the gear 3 and a brake 2 is mounted.
  • the brake 2 and the electric motor 1 with the transmission 3 are arranged on opposite sides of the press housing 4.
  • a press shaft 5 is arranged between the brake 2 and the transmission 3 or electric motor 1.
  • the brake 2 should now be arranged between the electric motor 1 and the transmission 3 and in particular not separately at the end of the press shaft 5, which is opposite to the electric motor 1 and the transmission 3.
