Abstract

A rudder (100) for watercraft (10), in particular for ships (11), is proposed, comprising a rudder shaft (14) arranged in a trunk pipe (12), a rudder blade (16) connected to the rudder shaft (14) anda bearing bushing (32) arranged between trunk pipe (12) and rudder shaft (14) as well as a bearing clearance measuring device (25), wherein the bearing clearance measuring device (25) comprises at least one sensor (26, 26a) for abrasion-free measurement of a bearing clearance.

Description

technical field [0001] The invention relates to a rudder for watercraft, in particular for ships, comprising a rudder shaft arranged in a main pipe, rudder blades connected to the rudder shaft, a bearing arranged between the main pipe and the rudder shaft Bushing and bearing clearance measuring device. The invention also relates to a measuring method for bearing play in a rudder and a bearing play measuring device for a rudder. Background technique [0002] Rudders for marine craft, in particular for ships, comprise rudder blades fixed to the rudder shaft. The rudder shaft is usually guided rotatably about a rudder shaft axis arranged in a main tube at the stern. At least one bearing bush is provided for mounting the bearing shaft in the main pipe, which bearing bush is preferably arranged in the region of the lower end of the main pipe. [0003] Due to the high forces generated during operation, the bearing bushes are subject to severe wear, which can lead to damage to t...
