Abstract
An extremely simple Permanent Magnetic Linear Shaft Coupler is presented that would magnetically couple the linear motion of a hermetically sealed shaft with an Actuator that operates in ambient conditions. The proposed Coupler will eliminate potential leak paths for the cryogenic valves at the Kennedy Space Center. The Coupler consists of only three parts and is based upon permanent magnets acting through a non-magnetic medium. The Coupler utilizes an outer and inner set of many flat, washer-shaped permanent magnets. The inner magnets easily fit within the hole of the outer magnets. A leakproof Linear Shaft Coupler that can withstand adverse conditions is immediately needed in the hazardous chemical, cryogenic and nuclear Industries.
