Definitions
- the present invention relates to a screening machine for dewatering and / or classifying granular substances such as gravel, Coal or ore, with a sieve frame attached to a machine frame is held, and with an elliptical vibration drive with two eccentric shafts that have different imbalances have and the synchronous and counter-rotating by means of the drive are driven.
- a screening machine with these features is from the publication "Screening machines with elliptical vibration and dynamic Drive ", preparation technology No. 7/1982, pages 367 to 372, known that a linear drive for dewatering and classifying of gravel, sand and the like. With this machine the masses producing the unbalance sit on two shafts. This Eccentric shafts are at an angle of 40 ° to 50 ° to the main direction of vibration arranged and synchronized via gear transmission. The main range can be the same or unequal masses in their linear or elliptical form and change size.
- the main disadvantage of this known Embodiment is that very synchronous hammer in high tooth flank forces in positive and negative direction, which affects the smoothness and also a increased temperature occurs in the gearbox. Another essential one The disadvantage is that an expensive special gear is used is, its susceptibility to failure and failure rate very is high. When changing the eccentric shaft distance is above another gearbox is necessary.
- DE-23 56 542 B2 describes a screening machine with a three-shaft drive known in which the main swing direction by the axis of the third, centrally arranged shaft runs.
- the invention has for its object a vibration drive of the type mentioned in such a way that in compliance a low overall height of the machine Vibration patterns set and the direction of vibration changed can be, in particular also operating noise and temperatures can be reduced.
- immediate proximity means that the Resultant of the mass forces of the unbalance so close to the center of mass the sieving machine attacks that by the deviation caused seesaws of the screening machine their own damping does not exceed.
- An advantageous embodiment is that the mass forces the unbalance are adjustable.
- eccentric shafts by means of V-belts or timing belts can be synchronized.
- V-belts or timing belts fixed to a motor console between the motors are also proposed.
- An advantageous embodiment provides that the eccentric shafts are driven by countershaft, the belt between the countershafts are attached.
- the invention has the particular advantage that the synchronization forces close to the belts or electrical components Are zero so that the drive does not flutter. Another The main advantage is that after starting the smaller motor can be switched off and the remaining forces the smaller unbalanced masses are taken over by the large motor, which results in an energy saving. Such energy saving also results from the reduced temperatures and running noise.
- the center distance of the eccentric shafts changes no new drive parts (e.g. gearbox) are required, the drive is also simplified overall by no additional drive units or a turbo coupling required are.
- the straps used cause by their Spring action damping. Pollution, such as can be avoided by oil leakage.
- the vibration drive shown in Figures 1 to 3 is on a sieving machine with a sieve box 1, sieve covers 2 and elastic bearings 3 attached.
- the actual vibration drive consists of two imbalances 7, 8, the unbalanced shafts or eccentric shafts 14, 15 am Sieve box 1 are stored.
- the drive of these eccentric shafts 14, 15 takes place via cardan shafts 5, 6, that of motors 9, 10 are driven on a stationary engine console are supported.
- the cardan shafts 5, 6 and thus also the eccentric shafts 14, 15 are synchronized, using synchronous waves 11, the belts 12, 13 with the motor drives 9, 10 are connected.
- the engine console 20 is on an engine stand 4 arranged. Furthermore, an eccentric shaft sits on both sides 14 or 15 an unbalance 7 or 8.
- the eccentric shafts 14, 15 as close as possible to the center of mass 16 of the screening machine are arranged.
- the unbalances 7 and 8 continue to rotate opposite and it results from the force diagram a swinging movement of the screen box according to the illustrated Ellipse (Fig. 1 and 5), the main swing direction 18 coincides with the longitudinal axis 19 of the ellipse 21.
- 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 vibratory forces is the least.
- the angle ⁇ between them Line 17 and line 18 is preferably 90 °, being still satisfactory results in the range up to 60 ° can be achieved.
- the unbalances 7, 8 are on the Zero line 17, i.e. the line connecting the axes of the eccentric shafts 14, 15, facing each other, i.e. against each other by 180 ° twisted so that no angular accelerations or Angular delays of the unbalanced masses occur.
- the synchronization takes place of the two cardan shafts 5, 6 via a single one Synchronizer shaft 11 and a single belt 12 of the motors 9, 10 and the synchronous shaft 11 connects.
- FIG. 5 shows the force diagram.
- the two dashed circles symbolize the circumferential unbalance 8 or 7, with the unbalance 7 shown in two dimensions is, namely as a smaller unbalance 7 and dash-dotted as greater unbalance 7 '. Accordingly, there is a Ellipse 21 or an ellipse 21 'for the larger unbalance 7'.
- the resultant can be calculated using the parallelogram of forces generate whose locus is the ellipse 21.
- Some points of the Unbalance positions are shown, namely points 0 to 6 or 0 'to 6'. From the illustration it can easily be seen that the angle between the large ellipse axis 19 and the zero line 17 is 90 °.
- the mass forces can be changed by changing the unbalance set the required shape, as well as the angular position Main vibration direction 18, either manually or electrically.
- the synchronization of the two eccentric shafts 14, 15 can also through an electrical synchronization synchronization control respectively.
- the eccentric shafts 14, 15 can also be provided with a countershaft drive, with the appropriate drive belts then are attached between the countershafts.
