Abstract

The backstop screw used in the wire actuator shown in [*] should be mad of a hard non-magnetic material in order to prevent a breakdown of the device after lengthy operations. This is due to the large amount of force with which the actuator strikes the backstop.

Satellite Insert for Actuator Backstop

The backstop screw used in the wire actuator shown in [*] should be mad of a hard non-magnetic material in order to prevent a breakdown of the device after lengthy operations. This is due to the large amount of force with which the actuator strikes the backstop.

The figure shows the backstop consisting of a screw portion 10 of non- magnetic material, such as stainless steel, and a stellite material insert 12 brazed against the screw. The insert 12 can also be press fit or bonded to the screw portion 10. When the actuator strikes the stellite insert, its high strength prevents the backstop from breakdown. Reference [*] L. R. Siegl, ""Magnetic Shielding of Print Wire Actuator,'' IBM Technical Disclosure Bulletin 23, 3545 3546 (January 1981).
