【 摘 要 】

In this article the authors solve the problem of determining a stiffness coefficient of stern shaft bearing with mechanical and geometrical parameters of the ship shafting and stern bearings. The influence of the stiffness coefficient on transverse and parametric vibrations is investigated. The dependence of the Ship's Shafting of tension state and deformation of stern bearing is shown. The equation for determining the stiffness coefficient is obtained. The numerical value of the stiffness coefficient of feed bearings of some types of vessels is presented.
