Research on Contact Strength between Roller Screw Pair on Hoisting Mechanism Applied in Deep Sea Crane

Abstract:

Roller screw pair is the major part of the rope guiding device that used in deep-sea hoisting mechanism. This paper focuses on the contact problems of the roller screw pair. The hoisting mechanism used in the deep sea engineering has the rope with large diameter, sustaining the great rope tension force. So its important to research the contact stress of the roller screw, This paper study the impact of surface hardness of the roller on the performance of the roller screw, sums up the effect of hardness on the bearing capacity of the roller, and provides the theoretical support and references for the designing and application of this new type of roller screw in marine engineering.
