Design and Manufacture Research of Jack-up Platform Jacking System

Abstract

The self-promotion platform jacking system has been dependent on imported equipment for a long time, independent research and development made the jacking system. According to the characteristics of operating conditions, the static bending strength of the tooth root of the climbing gear under the storm maintenance load was checked, and the calculation results of the three strength checking methods were given and compared. The gear material is made of high-quality alloy steel 40CrNiMo, which guarantees the good comprehensive mechanical properties after the heat treatment. By improving the CNC cutting machine, CNC flame cutting process produced crude tooth, adopting the precision CNC gear milling process made of refined tooth.
