TORQUE TRANSFER APPARATUS AND METHODS OF USE

A torque transfer apparatus and method of use is described. The apparatus (60) comprises a plurality of elements (62) assembled together to form a ring structure oriented in a plane around a longitudinal axis. The ring structure defines a first engagement surface. A structure (56) defining a second engagement surface is rotatable with respect to the ring structure. The ring structure is operable to be moved between a collapsed condition and an expanded condition by movement of the plurality of elements, and movement between the collapsed condition and the expanded condition engages or disengages the first and second engagement surfaces. The apparatus can be configured to transfer a driving torque (e.g. a clutch) or a braking force (e.g. a torque brake).

RELEASING LINEAR ACTUATOR

... 90R041 The present invention is useful for quickly releasing an object which is being moved by an actuator. Generally actuators of the piezoelectric type move objects slowly. For applications where an object must be quickly moved such as when releasing brakes or reinserting a control rod in a reactor core an actuator should have a quick release feature. The invention uses a set of actuators which contact a bolt and moves the bolt with smooth walking motion. The bolt in turn is driven by the actuators such that it engages an object with smooth walking motion to move or position the object. When the object is to be released the actuators are removed from contact from the bolt thereby releasing the object. 0013S ...

Patent JPH0568194B2

PURPOSE:To improve the braking effect with a simple construction by producing a frictional force between a rod and an electrostrictive element by the increase in the volume of the element. CONSTITUTION:When a piston 28 is stopped, positive voltage is applied from lead wirings 44 to an electrode plate 40, and a negative voltage is applied from the lead wirings 46 to an electrode plate 42. Thus, a radial displacement is induced in a laminated ring-shaped electrostrictive element 36 to press a brake element 36. Accordingly, the element 36 presses the peripheral surface of a piston rod 26, thereby stopping the reciprocating operations. Since the radial displacement of the element 38 instantaneously occurs, the brake operation is performed substantially the same time as the application of the voltage.
