Turning gear for ship having helical planetary reducers, design methods thereof and, computer readable recording medium having computer programs executing the design methods

摘要

The turning gear according to the present invention is made of a helical planetary reducer, but since the bite rate of the helical gear is a positive integer, shock, vibration, and noise can be reduced. Since the main shaft is integrally formed, the manufacturing process is simple. It is characterized in that the support member is fastened by a spline and the support member is supported by a tapered roller bearing. In addition, in the turning gear according to the present invention, since the gear twist of the sun gear of the third planetary reduction part, the planetary gear and the ring gear is formed in the opposite direction to that of the sun gear, the planetary gear and the ring gear of the first and second planetary reduction parts, the axial direction The load can be reduced, and accordingly, the existing shaft can be used as it is and a tapered roller bearing having a smaller size can be installed.
