Definitions
- Attenuation blocks also known as silent blocks, are known as
- the shock absorbing material is for example rubber or plastic foam and absorbs the transverse forces in the second spring element perpendicular to the drive shaft.
- the damping blocks are attached directly to the wall of a housing.
- Flat spring elements are inexpensive to produce in different materials and under tight geometrical and material tolerances. Most are spring steel or fiber reinforced plastic. The latter offers increased resistance to alternating stress while maintaining high strength and a low weight. In addition, the modulus of elasticity and thus the oscillation behavior of the leaf spring can be preselected by a suitable choice of the plastic.
- the flat spring elements show in the stress condition described an enormous longevity even under high alternating loads. They are also compact and lightweight compared to conventional coil springs.
- the design of the spring system of the inventive device allows greater forces and amplitudes of several millimeters at a frequency of up to 200Hz can be achieved.
- the apparatus can be used for mixing and homogenizing volumes on the order of 10O00L.
- the use of a permanent magnet or a magnetizable element as a counterpole to the electromagnetic drive can provide benefits depending on the application. With the use of a permanent magnet under otherwise identical conditions, the device according to the invention generates half the oscillation frequency with respect to the device with a magnetizable element. Especially at low operating frequencies, the use of permanent magnets can thus increase the drive efficiency, since the electromagnetic drive can usually be operated more efficiently at higher input frequencies. Also, the mechanical and thermal properties of the magnetizable element, usually consisting of ferritic material, or the permanent magnet, usually neodymium-iron-boron compounds can be advantageously used depending on the application requirements.
