Filed:

Dec 22, 1986

Appl. No.:

6/944927

Inventors:

Daniel R. Dobbs - Sunnyvale CA

Assignee:

Sundstrand Corporation - Rockford IL

International Classification:

F42B 1901

US Classification:

114 23

Abstract:

An interior actuation system for controlling an exterior control surface of a torpedo or the like which has an afterbody with radial inlet vanes defining inlet liquid passages to the propellers of the torpedo. A linear actuator is mounted in the afterbody. A bell crank is connected at one end to the linear actuator and extends radially outwardly therefrom through one of the inlet vanes. A driving connection, including a link arm connected at one end to the opposite end of the bell crank, extends longitudinally from the bell crank through the afterbody outside the liquid passages and operatively interconnects the control surface to the linear actuator.

Abstract:

Unequal loading in multiple load path transmissions having independent gear trains 18, 20, interconnecting an input and an output shaft 12 and 14, respectively, is avoided through the use of a torsionally compliant gear 22 located in each gear train 18 and 20. Each torsionally compliant gear 22 includes a hub 40 and a ring 46 having external gear teeth 48 about the hub 40 in concentric spaced relation. A body 50 of elastomeric material is disposed between the hub 40 and the ring 46 and spring fingers 68 carried by the ring 46 at least somewhat radially extend toward the hub 40. Stops 84 are carried by the hub 40 and are positioned to be normally spaced from the spring fingers 68 when low loads are transmitted by the gear and to engage the spring fingers 68 when predetermined higher loads are to be transmitted by the gear.
