Abstract
A device for receiving and separating chips and coolant discharged from machine tools having a filter drum that has an internal bearing ring on each of its two ends, which each engage in an external bearing ring so that they rotate together. Spring elements, which run parallel to the axis of the filter drum, may be provided which are supported on one side on the internal bearing ring and on the other side on the external bearing ring. Sealing elements may be provided to prevent undesired flow of unfiltered coolant.

1-6. (canceled)
A device for receiving and separating chips and coolant, comprising a filter drum rotatably mounted in a housing, the filter drum comprising:
- a. an internal bearing ring on each of two ends of the filter drum, each internal bearing ring engaging a corresponding external bearing ring so that the internal bearing ring and the external bearing ring rotate together;
- and
- b. at least one spring element that runs parallel to the axis of the filter drum and is supported on one side on the internal bearing ring and on the other side on the external bearing ring.
The device of claim 1 1, wherein the spring element is seated in the bore.
A device for receiving and separating chips and coolant, comprising a filter drum rotatably mounted in a housing, the filter drum comprising:
- a. an internal bearing ring on each of two ends of the filter drum, each internal bearing ring engaging a corresponding external bearing ring so that the internal bearing ring and the external bearing ring rotate together;
- b. at least one bearing shell fixed to the housing, the bearing shell having a surface against which a surface of the external bearing ring slides;
- and
- c. means for compensating for wear between the external bearing ring and the bearing shell.
The device of claim 19, wherein the spring element is seated in the bore.
A device for receiving and separating chips and coolant, comprising a filter drum rotatably mounted in a housing, the filter drum comprising:
- a. an internal bearing ring on each of two ends of the filter drum, each internal bearing ring engaging a corresponding external bearing ring so that the internal bearing ring and the external bearing ring rotate together;
- b. a bearing shell in which the external bearing ring is seated;
- the bearing shell being fixed to the housing;
- and
- c. means for sealing the filter drum to prevent unfiltered coolant from passing into the interior of the filter drum.
