Abstract
A rheometer has a rotor comprising a shaft which is seated with play in a recess of a bearing block and is supported contact-free in a radial and/or axial direction by an external air cushion which acts in a bearing section. To provide for simple and inexpensive production of an air bearing having a high loading capacity, the wall of the recess in the bearing section is continuous without bore-holes, and consists of air-permeable material. The bearing air loads the side of the wall facing away from the shaft and penetrates through the wall.
Claims11
A rheometer comprising:
- a bearing block having a continuous wall section, without bore-holes, made from an air-permeable material, said continuous wall section defining a recess;
- a rotor having a shaft, said shaft disposed with play in said recess of said bearing block;
- and
- means for applying pressurized bearing air to a side of said wall section facing away from said shaft, wherein said bearing air penetrates through said wall to form an external air cushion within said recess for supporting said shaft in a contact free, radial and/or axial direction.
