Abstract
The invention relates to a protection device for a motor spindle (1) arranged in a housing (2), particularly of a machine tool, having an inner ring (6) fixedly joined to the motor spindle (1) and an outer ring joined to the housing (2). The inner ring (6) is arranged in the outer ring (7) in a way permitting axial motion and a tilting motion, and is placed under elastically resilient preload against the outer ring (7) by means of preloading members (8).
Claims10
A protection device for a motor spindle, the motor spindle arranged in a tool housing and rotatable about a central axis that defines an axial direction and a radial direction, the protection device comprising:
- an inner ring fixedly joined to the motor spindle;
- an outer ring joined to the housing;
- preloading members applying an elastically resilient axial preload in the axial direction to the inner ring against the outer ring;
- and
- radial damping elements arranged between the inner ring and the outer ring and providing a dampening force in the radial direction operative to dampen vibrations,
- wherein the inner ring is arranged in the outer ring in a way permitting axial motion of the motor spindle along the central axis and a tilting motion of the motor spindle radially away and toward the central axis.
