Mounting adapter having locking taper removal arrangement
First Claim
1. A mounting adapter for a centrifuge rotor, the mounting adapter being receivable on the end of the drive spindle itself having a threaded bore therein and a frustoconical locking taper surface thereon, the mounting adapter comprising;
- a spud member having an internal chamber therein, the chamber being defined in part by a first, locking, surface and a second, lifting, surface, the spud member having an threaded access bore and a mounting bore extending therethrough, the mounting bore being bounded by a tapered surface corresponding in shape to the frustoconical locking taper surface on the spindle, both the access bore and the mounting bore being in communication with the internal chamber; and
a connecting member having a head and a threaded shank thereon, the head being confined within the internal chamber with the shank extending into the mounting bore, the connecting member being rotatable in first and second opposed angular directions by a tool extendable through the access bore into engagement with the head of the connecting member,rotation of the connecting member in the first angular direction threadedly engaging the shank with a threaded bore disposed in a drive spindle and bringing the head into abutting contact with the locking surface thereby to impose a locking force acting in a first direction on the spud member to hold the mounting surface thereon and the frustoconical surface on the spindle in locking engagement,rotation of the threaded member in the second angular direction unthreading the shank from the threaded bore in the spindle and causing the head to abut against the lifting surface thereby to impose a lifting force acting in a second, opposed, direction on the spud member to assist in separating the mounting surface on the spud member from the frustoconical surface on the spindle.

Abstract
A mounting adapter for a centrifuge includes an internal chamber having a lifting and a locking surface therein. The head of a connecting member is captured in the chamber and is rotatable by a tool insertable through an access bore in opposed angular directions. Rotating the connecting member in one direction brings it into abutting contact with the locking surface to hold tapered surface surfaces on the adapter and on the spindle in locked engagement. Rotation of the connecting member in the opposed direction causes the same to abut against the lifting surface to assist in separating the tapered surface from each other.

5. A mounting adapter for a centrifuge rotor, the mounting adapter being receivable on the the end of the drive spindle itself having a threaded bore therein and a frustoconical locking taper surface thereon, the mounting adapter comprising:
a spud member having an internal chamber therein, the chamber being defined in part by a first, locking, surface and a second, lifting, surface, the spud member having an access bore and a mounting bore extending therethrough, the mounting bore being bounded by a tapered surface corresponding in the shape to the frustoconical locking taper surface on the spindle, both the access bore and the mounting bore being in communication with the internal chamber, the spud member itself comprising; an outer shell having a threaded cavity therein, the lifting surface theron and the access bore therethrough; an insert receivable in the cavity in the outer shell, the insert having the locking surface thereon and the mounting bore therethrough, and a clamp ring engaging the threads in the outer shell to secure the insert within the outer shell; and a connecting member having a head and a threaded shank thereon, the head being confined within the internal chamber with the shank extending into the mounting bore, the connecting member being rotatable in first and second opposed angular directions by a tool extendable through the access bore into engagement with the head of the connecting member, rotation of the connecting member in the first angular directin threadedly engaging the shank with a thread bore disposed in a drive spindle and bringing the head into abutting contact with the locking surface thereby to impose a locking force acting in a first direction on the spud member to hold the mounting surface thereon and the frustoconical surface on the spindle in locking engagement, rotation of the threaded member in the second angular direction unthreading the shank from the threaded bore in the spindle and causing the head to abut against the lifting surface thereby to impose a lifting force acting in a second, opposed, direction on the spud member to assist in separating the mounting surface on the spud member from the frustoconical surface on the spindle.
