Abstract
A setting device for the control surface of a projectile, which includes a drivable spindle or actuated screw which is screwed through the intermediary of a nut which is secured against rotation. Included are end stops for limiting the axial extent of displacement of the nut when stop surfaces which rotate in conjunction with the spindle contact in the direction of rotational movement, a stop against a stop surface axially-parallel protruding from a single-threaded helicoid surface on one or the other end face of the nut.
Claims9
Setting device for the control surface of a projectile, including a drivable spindle;
- a nut secured against rotation having said spindle screwed therethrough, end stops arranged on said spindle secured against rotation and being axially adjustable along said spindle, each said end stop consisting of two mating parts so as to form a locknut structure for limiting the axial extent of displacement of the nut, each said end stop including a contact surface rotatable with the spindle so as to contact in the direction of rotational movement against a contact surface formed from a single screwthread and axially projecting from one or another opposite end surface of the nut, contact surfaces on the ends of the end stops facing said nut which are complementary to the contact surfaces of the nut and which, upon contact between one of the contact surfaces and complementary contact surface, engage with an adjacent end surface of the nut.
