Definitions

  • the invention relates to a displacement machine for compressible Media, especially dry-running vacuum pump, with at least two shafts with rotors, which are designed as profile bodies and their profiles are gear-like when rotating intermesh and run without contact to each other, whereby the shafts are each driven by their own electric motors be, the angular positions of the shafts with resolvers the motors are determined on the basis of their signals be electronically synchronized, and being the waves Have gears that mesh and their angular play is smaller than that of the profile body.
  • the object of the invention is a displacement machine to create the type mentioned, in which the "Zeroing" the rotors and gears easily, quickly and can be set exactly with the help of the resolver.
  • the solution according to the invention is that at least one the gears directly with the resolver's rotor Axis and both together as a unit detachable with the shaft are connected.
  • the "zero position" or backlash is set according to the invention in the following way. It will be first a rotor to which the gear and the resolver are releasably attached is held. The gear can rotate run relative to the axis of this one rotor. The other rotor will then turn in either direction up to one Position rotated in the flanks of the profile body touch. The two contact angles are measured, and the rotor with its gear attached to it Set the middle position between these two angles and captured.
  • the first rotor is also still held. It but now the gear of the first rotor in both directions each up to the point of contact with the gear of the other rotor rotated. The contact angles are also found again. Then the gear is on the Set the mean of these two points of contact and firmly connected to the corresponding shaft, in particular clamped by tightening screws. Both the rotors or profile body as well as the gears exactly in the middle position between the two positions, where they touch or would touch. this is the Reset, with the value of which the synchronization is then carried out by carrying out the regulation so that the relative position of the two shafts, rotors and gears corresponds to this value as far as possible during operation.
  • the gears are advantageously attached to one shaft end, because they are particularly easy to access what attaching the initially loosened gear to its shaft facilitated.
  • the displacement machine advantageously has a differential control for the speed of the motors.
  • Synchronization with the setting of the backlash or the "zero position" is already a well synchronized Operation reached.
  • the operational behavior is still improved, if both rotors are not set to one independently Setpoint to be synchronized, but the synchronization primarily due to differences in angular positions he follows. For example, liquid penetrates the Pump room one, because of the opposite gases the rotors strong a thousand times higher density of the liquid braked, but the braking for both rotors approximately done immediately. Any differences that may exist then be compensated for by the synchronization. This would be not the case when the synchronization is from outside predetermined value would take place. Of course you will find but also an additional regulation from the outside instead to the to be able to enter the desired speed. This regulation, that works in the same sense on both motors, but is proportional slow so that rapid speed differences be eliminated by the difference control.
  • Fig. 1 there are one of several Parts of assembled pump housing 1 with bearings 2 two shafts 3 stored on which profile body 4 are attached, which interlock and in the pump chamber 5 through a connection 13 that Suck the medium to be pumped from above and not through the bottom Eject the openings shown.
  • the waves 3 and the profile body 4 are driven by electric motors 6, whereby for each shaft 3 a separate electric motor 6 is provided.
  • the motors 6 are made using resolvers 8 electronically synchronized. In adverse operating conditions, if the electronic synchronization is not sufficient, first touch the gears 7 because they are less Have angular play as the rotors 4. Usually touch but not the gears 7, so that lubrication these gears can be dispensed with.
  • Fig. 2 shows a section of the illustration of Fig. 1 in enlarged scale.
  • the gear 7 connected to the resolver rotor 9, which is opposite the shaft 3 is rotatable.
  • the gear 7 can in turn with the help of Clamping element 13 are fixed on the shaft 3.
  • the rotor 11 of the resolver 8 is arranged while the stator 12 of the resolver 8 is arranged fixed to the housing.
  • both the rotors 4 and the gears 3 is first in 1 right rotor 4 with its shaft 3, the screw 10 is loosened so that the right gear 7 can rotate.
  • the left wave 3 is then in rotated in both directions until the rotors 4 touch, taking these two contact angles using the resolver 8 can be determined.
  • the left wave 3 will then to the mean between these two points of contact set.
  • the right shaft 3 of the right rotor continues captured. It will then be the one on the right Gear 7 moves in both directions until it is touches left gear.
  • the two contact angles are with the right resolver 8 measured.
  • the gear 7 is then on set the mean between these two angles and is tightened with the screw 10. Both rotors 4 and both gears 3 are thus in the middle position between the points of contact. At this value the relative angle the operation is then synchronized.
