水下工程用液压绞车的研究和设计

Design of Hydraulic Winch for Underwater Engineering

用液压马达拖动的绞车,在船舶甲板设备及地面工程设备中,已经得到了成功的应用。在理论上及实践中出现的问题亦得到比较完满的解决。但是,把同样的结构移到海水中,特别是在深海作业的海洋工程设备中工作,就出现了一些新的问题。主要是密封问题及防腐蚀问题。

This paper copes with the sealing and corrosion-protection of hydraulic winch and problems met in its design and type selection in regard to the friction between the ball and the plunger socket, the contact strength between the ball and the cam, and the calculation of cam curves.
