A device for the production of moldings from a compressible mixture, vibrating table and vibration exciter

摘要

A device for the production of moldings from a compressible mixture, in which the compression takes place under the action of mechanical vibrations, comprises a vibration exciter with a vibration body (5), one on the latter about its longitudinal axis (l) rotatably mounted main shaft (6), a gyroscope (8), which is connected with the main shaft (6) and connected by a top spindle (k) is rotatable, wherein the top spindle (k) are not - parallel to the longitudinal axis (l) of the main shaft (6) is arranged, as well as drive means, around the main shaft (6) and the gyroscope (8) is set in rotation about the respective axis (l, k) to be displaced. In addition, a vibration exciter is proposed that the one or more imbalance masses (10) on its main shaft (6) comprises. Furthermore, a vibrating table is described, in the other be influenced by means of a gyroscope excitation. In all cases, in a simple manner through the oscillating behavior can be influenced, the speed of rotation of the gyro.
