The article deals with the structure of the tangent-type mechanism used in modern ship hydraulic ram-type steering gears. A structural analysis of the FLUTEK-KAWASAKI FE 21-243 steering gear mechanism with roller rams-to-tiller connection was performed. As a result, it is shown that the mechanism of this machine contains 16 redundant constraints. It is shown that the reasons for the occurrence of these constraints are the necessity to prevent the rams rotation around their own axes (for this purpose, the FLUTEK-KAWASAKI machine uses guide beams installed parallel to the rams) and the load transfer from the rams to the tiller in two streams (for which two rollers with both sides of the plungers are installed). The main directions for improving the structural perfection of the steering gear mechanism are proposed. Proposed the new structural diagram of the tangent-type steering gear mechanism, where it is possible to reduce the number of redundant constraints more than twice (from 16 to 6) through the guide beam excluding and one stream working force transfer from plungers to tiller.
