Definitions
- the present invention relates to a screening machine for dewatering and / or classifying granular Materials such as gravel, coal or ore, with one Screen frame held on a machine frame is, and with an elliptical vibration drive with two eccentric shafts, the different imbalances and synchronously and in opposite ways be driven by the drive.
- a screening machine is known from US 3,226,989.
- a screening machine with these features is out the publication "screening machines with elliptical Vibration and dynamic drive ", treatment technology No. 7/1982, pages 367 to 372, which is a linear actuator for draining and classifying of gravel, sand and the like.
- This Machine sit on two waves causing imbalance Masses.
- These eccentric shafts are at an angle from 40 ° to 50 ° to the main vibration direction arranged and synchronized via gear transmission.
- the main swing can be the same or unequal masses in their linear or elliptical Change shape and size.
- the most essential Disadvantage of this known embodiment is in that during synchronous running very high tooth flank forces hammering in positive and negative direction, whereby the smoothness is impaired and also a increased temperature in the transmission occurs.
- Another major disadvantage is that an expensive Special gear is needed, its susceptibility and default rate is very high.
- When changing the Eccentric shaft spacing is also another Transmission necessary.
- From DE-23 56 542 B2 is a screening machine with a three-shaft drive known in which the main swing direction through the axis of the third, centered arranged wave runs.
- the invention is based on the object, a Vibration drive of the type mentioned so form that while maintaining a low height the machine different vibration patterns set and the swing direction to be changed can, in particular also operating noise and Temperatures are reduced.
- An advantageous embodiment is that the inertial forces of the imbalances are adjustable.
- Keii or Timing belt on a motor console stationary between the motors are attached.
- An advantageous embodiment provides that the eccentric shafts are driven via countershaft, the straps being mounted between the countershafts are.
- the invention brings in particular the advantage that the synchronization forces on the belts are close to zero, so that a flutter of the Drive is eliminated.
- Another significant advantage is that after starting the smaller Engine can be turned off and the residual forces the smaller imbalance masses taken over by the big engine which results in energy savings results. Such an energy saving also results due to the reduced temperatures and running noise.
- With a change in the axle distance of the eccentric shafts are no new drive parts (eg gearbox) required, whereby the drive is simplified as a whole is by adding no additional drive units or a turbo coupling are required.
- the used Belts cause by their spring action a Damping. Pollution, such as Oil leakage can be avoided.
- the vibration drive shown in Figures 1 to 3 is on a screening machine with a sieve box 1, Siebbelägen 2 and elastic bearings 3 appropriate.
- the actual vibration drive consists of two unbalances 7, 8, over unbalanced shafts or Eccentric shafts 14, 15 are mounted on the sieve box 1.
- the propeller shafts 5, 6 and thus also the Eccentric shafts 14, 15 are synchronized, namely via synchronous shafts 11, which via belt 12, 13 with the motor drives 9, 10 are connected.
- the engine console 20 is arranged on a motor stand 4. Continue to sit on both sides of an eccentric shaft 14 and 15 an imbalance 7 and 8, respectively.
- the eccentric shafts 14, 15 as close to the center of mass as possible 16 of the screening machine are arranged.
- the imbalances 7 and 8 rotate in opposite directions and it is due to the force diagram a swinging motion of the sieve box according to the illustrated ellipse ( Figures 1 and 5), wherein the main vibration direction 18 with the longitudinal axis 19th the ellipse 21 coincides.
- the connecting line through the center of the eccentric shafts 14, 15 is the zero line 17, where in addition the resultant of the mass vibration forces is lowest.
- the angle ⁇ between this line 17 and the line 18 is preferably 90 °, with still satisfactory results in the Range can be achieved up to 60 °.
- In the "zero position" lie the imbalances 7, 8 on the zero line 17, i. the connecting line the axes of the eccentric shafts 14, 15, opposite each other, i. rotated by 180 °, so that no angular accelerations or angular delays the imbalance masses occur.
- Fig. 5 the force diagram is shown.
- the two dotted circles symbolize the circulating Imbalances 8 and 7, wherein the imbalance 7 in two Dimensions is shown, namely as smaller Imbalance 7 and dash-dotted as a larger imbalance 7 '. Accordingly, then there is an ellipse 21 or an ellipse 21 'at the larger imbalance 7'.
- Based of the parallelogram of forces can be the resultant generate whose locus is the ellipse 21.
- Some Points of the unbalance positions are indicated, and although the points 0 to 6 or 0 'to 6'. From the presentation is readily apparent that the angle between the large ellipse axis 19 and the zero line 17 is 90 °.
- the Eccentric shafts 14, 15 can be driven via countershaft, wherein the corresponding drive belts then between the Countershafts are attached.
