Abstract
A sleeve is provided with a clamp for removably clamping the sleeve on a mandrel. A rigid ring is mounted inside of the sleeve at each end of the sleeve. Each ring has a generally cylindrical inside surface which includes a curved contact portion which extends for less than 180 degrees and which is engageable with the outside surface of the mandrel. A curved clamp arm is pivotally secured at one end thereof to each ring. An eccentric shaft extends through an opening in the other end of the clamp arm. Rotation of the eccentric shaft moves the clamp arm toward the contact portion of the ring so that the mandrel can be clamped between the clamp arm and the contact portion.
Claims11
A sleeve assembly adapted to be mounted on a mandrel comprising:
- a tubular sleeve having a pair of ends and inner and outer surfaces,
- a ring secured to the inner surface of the sleeve adjacent one end thereof, the ring having an inside surface with a contact portion which is adapted to locate a cylindrical mandrel extending through the ring,
- a clamp arm movably mounted on the ring, the clamp arm having a contact portion which is spaced from the contact portion of the ring and which is adapted to engage a mandrel extending through the ring, the clamp arm being movably mounted on the ring so that the contact portion of the clamp arm is movable toward the contact portion of the ring whereby a mandrel can be clamped with repeatable preload between the contact portions of the ring and the clamp arm.
