Definitions
- the invention relates to a device for driving a screening machine having at least one screen body.
- the imbalance weights are arranged on two continuous shafts, wherein a transmission in addition to the oscillating part of the machine, for. B. the screen box, is fixed.
- the waves of the imbalance weights are connected by drive shafts or similar parts with the transmission outputs.
- the unbalance weights carrying continuous waves are designed as rigid or propeller shafts.
- a drive unit originating from the applicant includes a
- An unbalance drive for generating linear vibrations of large machine screens, wherein the vibration excitation takes place by so-called double unbalance transmission comprises two axially parallel in a housing mounted shafts with imbalance discs located thereon, whose oppositely directed rotational movement is synchronized by a pair of gears within the housing.
- the unit forms an imbalance module.
- One of the two shafts protrudes from the housing on both sides, is driven on one side and can drive another such unbalance module via the other end of the shaft.
- This drive unit contains sufficient to achieve this
- Oscillating power six unbalance modules mounted on the screen body are arranged in two paraxial groups on trusses. It is driven by a non-resonating stationary unit consisting of an electric motor and a strong synchronization gearbox next to the screening machine. This relatively large space on the screening machine is required and it is an unnecessarily high "dead" resonating mass of Imbalance modules, because of the existing in this additional synchronous gears, the oil lubrication and the necessarily massively built gear housing., Available.
- Task underlying to provide an imbalance drive for a strainer of a screening machine high throughput which does not have these disadvantages, but whose with the screen body mitschwingende mass exceeds the sum of its imbalance masses as little as possible and its imbalance mass can be changed modular.
- Axial direction of the waves between the imbalance elements exclusively bearing elements arranged on the shafts and the bearing elements are supported on a cross member connected to the side walls.
- imbalance modules groups of unbalance elements together with their bearings are combined to imbalance modules.
- Each of these imbalance modules can be surrounded by a housing and also the associated shaft section include. It is also conceivable to provide only parts of the imbalance and the bearing elements within a housing.
- Cardan shaft are in operative connection. This is where the
- the invention particularly relates to the generation of linear vibrations of the screen body, but is not limited thereto.
- Figures 1 and 2 a principle constructive structure of the inventive concept in different views
- Figures 3 and 4 a partial view of an imbalance module in different views
- Figures 5 and 6 a basic structure of the inventive concept, differently shaped storage area.
- Figures 1 and 2 show schematic diagrams of a screening machine 1.
- the screening machine 1 is driven by a drive motor V, which is connected via a drive shaft 2 with a synchronous transmission 3.
- the synchronous transmission 3 has two axis-parallel output shafts 4, 5.
- the screening machine 1 is here shown only partially and includes a
- the universal joint 10 engages the end region 11 of the first shaft section 8.
- the individual shaft sections 8 are connected via torsionally rigid compensation couplings 12 with each other.
- the reference numeral 13 the actual sieve is indicated.
- FIGs 3 and 4 show in different views a single unbalance module 7. It is a housing 14 is shown, which includes a portion of the imbalance module 7. Each unbalance module 7 includes three spaced unbalance elements 15, 16, 17 which are mounted on a shaft portion 8. Between individual unbalance elements 15, 16, 17 bearing elements 18, 18 'are positioned. In this example, the unbalance elements 15, 17 are arranged outside of the housing 14. Each imbalance module 7 includes attachment areas 22, by means of which it can be fastened to it in the region of the associated crossbar 21 (see also FIG. 2).
- FIGS 5 and 6 show once again the schematic structure and the function of the imbalance drive according to the invention. Shown are in an indicated form the screening machine 1, the Drive motor 1 ', the drive shaft 2 of the drive motor V 1, the synchromesh transmission 3 and its axis-parallel output shafts 4, 5.
- the synchronous transmission 3 includes at least one central gear 3' and two output gears 3 "In the field of screening machine 1, the side walls 6" Traverses 21 and imbalance modules 7 can be seen, which are each provided on a shaft section 8. Also visible are the provided on the first unbalance module 7 joints 9, 10 and arranged between the imbalance modules 7 torsionally rigid compensation clutches 12.
- the difference between the figures 5 and 6 is that at
- the reduced space requirement allows (with the same outer dimensions) the adaptation of significantly increased "active" imbalance masses and significantly less resonant "dead mass”. This allows alternatively longer sieve trays, higher throughput or smaller screening machines at the same throughput. This is cost-cutting and allows by minimizing the total weight and external dimensions of the Road transport also of screening machines with higher throughput than before.
- the device according to the invention is also readily applicable to conveyors, vibratory conveyors, Scrissalrinnen or similar devices.
