Rudder angle detecting device of steering gear

摘要

The inner cylindrical body (1) is mounted on the top surface of the rudder-stock (62); the outer cylindrical body (2) is put on the inner cylindrical body exteriorly; the gudgeon pin (2b) provided on the top reverse surface of the outer cylindrical body is inserted into the gudgeon (1c) provided on the top surface of the inner cylindrical body; the pin protruded on the top surface of the outer cylindrical body is inserted into the chest (3) fixated to the supports; the rotational movement checking device (34), that obstructs the pin to rotate, and at the same time, permits it to be displaced in the radial direction, is provided inside the chest; the scale (6) is provided on the outer circumferential surface of the inner cylindrical body; and, the rudder angle detecting optical sensors (7) facing the scale are mounted on the inner circumferential surface of the outer cylindrical body.
