Abstract

Es wird ein geräuscharmes Hydraulikaggregat mit einer Motor-Pumpe-Gruppe beschrieben, die einen Elektromotor und eine von diesem angetriebene Hydropumpe aufweist. Die Hydropumpe ist an dem Elektromotor gehalten. Der Elektromotor ist an einem Motorträger gehalten, der über Dämpfungselemente mit einer Grundplatte verbunden ist. Um ein derartiges Hydraulikaggregat zu schaffen, für dessen Aufstellung nur eine kleine Grundfläche erforderlich ist, ist die Motor-Pumpe-Gruppe senkrecht zu der Grundplatte angeordnet, ist der Motorträger in Form eines Tisches ausgebildet, dessen Platte parallel zu der Grundplatte angeordnet ist und die sich über vier Beine an der Grundplatte abstützt. Die Platte ist mit einer Ausnehmung für die an dem Elektromotor gehaltene Hydropumpe versehen. Dabei ist die Motor-Pumpe-Gruppe so an der Platte gehalten, daß sich der Elektromotor oberhalb der Platte und die Hydropumpe unterhalb der Platte befindet. Das Hydraulikaggregat läßt sich in vorteilhafte Weise bei Werkzeugmaschinen einsetzen, bei denen nur eine kleine Grundfläche für die Aufstellung des Hydraulikaggregats zur Verfügung steht.

Figure 00000001
It describes a low-noise hydraulic power unit with a motor-pump group having an electric motor and a driven by this hydraulic pump. The hydraulic pump is held on the electric motor. The electric motor is held on a motor carrier, which is connected via damping elements with a base plate. In order to provide such a hydraulic unit, for its installation only a small footprint is required, the motor-pump group is arranged perpendicular to the base plate, the motor support is in the form of a table whose plate is arranged parallel to the base plate and the supported by four legs on the base plate. The plate is provided with a recess for the hydraulic pump held on the electric motor. The motor-pump group is held on the plate so that the electric motor above the plate and the hydraulic pump is below the plate. The hydraulic unit can be used advantageously in machine tools, in which only a small footprint for the installation of the hydraulic unit is available.
