Definitions

  • the invention relates to a turbomolecular pump according to the preamble of claim 1.
  • the active pump elements of a turbomolecular pump consist of with blades provided rotor and stator disks, which are arranged alternately one behind the other are.
  • the rotor and stator disks generally each have an inner one Support ring, which is equipped with blades on the outside.
  • the shovels of the Rotor disks that rotate at high speed result in interaction with the stator blades the pump effect.
  • spacer rings which on outer circumference between the stator disks, they are spaced maintained that the rotor disks can rotate between them without contact.
  • Stator disks and spacer rings together form the stator through the inner wall the pump housing is centered and z. B. with springs additionally axially is pressed together in such a way that the stator disks and the spacer rings form a firm Form a network.
  • the stator disks are divided into two for reasons of assembly and thus consist of two half disks.
  • the object of the invention is to present a turbomolecular pump, where the number of components is clear compared to conventional designs is reduced. This should reduce manufacturing costs and assembly times as well the maintenance work is simplified. Avoiding leaks within the pump, which is due to the division of the stator disks, belongs also for the task. An improvement in the heat conduction from the inside of the pump externally, what is strived for is the safety of pump operation contributes.
  • the arrangement according to the invention increases the number of components of a turbomolecular pump significantly reduced. This can simplify production and easier, time-saving assembly is made possible. Compliance with the necessary Tolerances are made considerably easier by the reduced number of components.
  • the radial centering and the axial fixation of the stator washers given by the invention per se and require no further adjustment work.
  • the heat generated during operation of the pump can be transported to the outside due to a compact design and the avoidance of heat conduction inhibitors Transitions between the parts of conventional construction significantly improved become.
  • by attaching cooling or heating elements in the area of the stator elements a very effective temperature control of the whole Pump structure, but especially the pump-active parts, depending depending on the operating conditions of the pump.
  • the suction opening is 1 and Gas outlet opening designated 2.
  • the rotor shaft 4 is fixed in bearings 8 and 9 and is driven by the motor 6.
  • the rotor disks are on the rotor shaft 4 10 attached with clamps 24.
  • the one-piece stator elements 12 comprise each a part 17 of the cylindrical housing, the stator disks 14 and the spacer rings 16, which fix the distance between the stator disks. Between the individual stator elements 14, which one on the other in the axial direction are layered, there are sealing elements 20.
  • the stator elements become axial held together by means of screw connections 18 and on the lower part 22 of the Pump attached.
  • the rotor disks 10 are by means of clamping devices 24 attached to the rotor shaft 4.
