Abstract
A chucking apparatus for chucking an object contains a basic body which has a receiving space in which the object can be disposed. A chucking device is provided with a chucking nut which is screwable onto the basic body and by the chucking nut being screwed onto the basic body the object disposed in the receiving space can be chucked non-rotatably. The chucking nut has a plurality of roller bodies having a defined roller engagement structure. The roller bodies are held in an axially rotatable manner on a chucking body of the chucking nut and are arranged distributed in the circumferential direction on the chucking nut. The rollers by their roller engagement structure are in engagement with the basic body engagement structure of the basic body.
Claims21
A chucking apparatus for chucking an object, the chucking apparatus comprising:
- a basic body having a receiving space formed therein in which the object can be disposed;
- a chucking device having a chucking nut being screwable onto said basic body and by said chucking nut being screwed onto said basic body the object disposed in said receiving space is chuckable non-rotatably, said chucking nut having a sleeve-shaped chucking body and a plurality of cylindrical roller bodies each with a defined roller engagement structure defined by grooves formed in each of said roller bodies, wherein:
- said plurality of cylindrical roller bodies are held in an axially rotatable manner on said sleeve-shaped chucking body of said chucking nut and are disposed distributed in a circumferential direction on said chucking nut, or
- said plurality of cylindrical roller bodies are held and are disposed in an axially rotatable manner and distributed in the circumferential direction between said sleeve-shaped chucking body of said chucking nut and said basic body;
- said basic body having at least one basic body engagement structure formed therein, wherein said cylindrical roller bodies by means of said defined roller engagement structure are in engagement or can be brought into engagement with said at least one basic body engagement structure of said basic body;
- and
- said chucking nut is screwable onto said basic body and is unscrewable from said basic body by means of said at least one basic body engagement structure and said defined roller engagement structure which are in engagement with one another.
