摘要:
A rotor (10) for an electric motor has a force-transmission region (11) which is operatively connected to a motor shaft (12). A torque-transmission region (13) which is composed of fibre composite materials is adjacent to the force-transmission region (11). A magnetic connection region (14) and a region (15) for magnetic field guidance with magnets (16) are arranged on that side of the torque-transmission region (13) which is situated opposite the force-transmission region (11). The motor shaft can also be formed from fibre composite materials. Since the magnetic connection region (14) has a plastic which is provided with a magnetic or magnetizable filler, a rotor for an electric motor and also a motor shaft which interacts with said rotor which are of lightweight construction are provided, said rotor and motor shaft meeting the required performance criteria.

For a hydraulic device for supplying at least one load (30) with hydraulic medium on an injection molding machine for processing plastics, a temperature-control device for the temperature control of the hydraulic medium by means of a temperature-control medium is provided, said temperature-control device having a cooling line (15). The hydraulic medium is pumped to the load through at least one hydraulic line (12, 13) by means of a hydraulic pump (10), which can be temperature-controlled by the temperature-controlled hydraulic medium or by the temperature-control medium. A servomotor (20) for the hydraulic pump (10) is connected to the hydraulic pump (10). The hydraulic line (12') containing the temperature-controlled hydraulic medium and/or the cooling line (15) containing the temperature-control medium is led to said servomotor. Because the hydraulic line (12) and/or the cooling line (15) forms a cooling jacket for the hydraulic pump (10), favorable energy optimization is created for the temperature control of the hydraulic device.

The invention relates to a device for producing a three-dimensional object (50) from solidifiable material, which is present in a fluid phase, by the sequential discharging of droplets (70). Said device comprises at least one conversion unit for converting the solidifiable material to the fluid phase, at least one material store for the fluid phase, at least one pressure generating unit (60) which applies pressure to the fluid phase in the material store and at least one discharge unit (12) for discharging the solidifiable material through an exit opening in the direction of the three-dimensional object (50) to be produced. An object support (13) for the three-dimensional object (50) to be produced is movably guided on a bearing (40) so as to be mobile relative to the exit opening. According to the invention, the discharge unit (12) and the bearing (40) are non-rotatably connected, and the pressure generating unit (60) connected to the discharge unit (12) is movably mounted relative to the latter connection, thereby allowing the object to be produced with high precision.

The invention relates to a method and a device for producing a three-dimensional object (50) made of a material that can be solidified and that in the initial state is either present as a liquid or can be liquefied. For this purpose, the material that can be solidified is introduced into a material reservoir (18) in the liquid phase of said material. From there, the material is generatively discharged via an outlet opening of a discharge unit (12) in the direction of an object holder (13) for the three-dimensional object (50) to be produced. The object holder (13) or the three-dimensional object (50) and the discharge unit (12) can be moved relative to one another within the space. By feeding at least one continuous fiber element (61) at a distance from the outlet opening (12a) for the material that can be solidified to the object (50) and embedding said element at the three-dimensional object to be produced into the discharged material to be solidified simultaneously with discharging the material that can be solidified, the generative method provides for a method and a device for producing a three-dimensional object with improved material properties.
摘要:
A device for producing a three-dimensional object from hardenable material has a construction space (20) for constructing the object (50), a temperature control unit for controlling the temperature of the construction space (20), and a preparation unit (11) for preparing the hardenable material in such a way that the material is in the fluid phase. A pressure generation unit (10) applies pressure to the fluid phase in the preparation unit. A discharge unit (12) is provided for discharging the hardenable material through an outlet (12b) in the form of drops in the direction of the construction space (20). In order to optimize the energy required to control the temperature that promotes bonding of the material on the object (50), the temperature-controlled construction space (20) is surrounded by a construction space frame (18) in which at least the outlet of the discharge unit (12), the preparation unit (11), and the object support (13) for producing the object are accommodated.
