Abstract: In China, the rudder stock and tiller often utilize the hydraulic cone pressing method, which has the characteristics of simple construction and design, and high oil pressure. With the recent trend of the large-scale ships and the speeding up of the sea trails in the channel near the North Pole, the torque and the rudder force transferred between the tiller and the rudder stock have become larger and larger. It will increase the technical risk of the potential slip between the rudder stock and the tiller, resulting in the accidents of slip between the rudder stock and the tiller during the actual operation. The key hydraulic cone connection method has been innovatively utilized for the connection of the rudder stock and the tiller. The calculation method and the technical difficulties of the key hydraulic cone connection method are introduced and analyzed in detail, which can provide reference for the similar designs in future.

Key words: rudder stock, tiller, key hydraulic connection, calculation method, construction and cost

摘要： 目前国内舵杆与舵柄采用液压锥形压装方式,该方式具有施工及设计简单、压入油压高的特点。随着近年来船舶大型化和北极附近航道的船舶试航步伐加快的趋势,而舵柄和舵杆之间传递的扭矩和舵力越来越大,舵杆与舵柄发生潜在滑移的技术风险增大,在实际营运过程中会发生舵杆与舵柄滑移事故。文中将舵柄与舵杆创新地采用有键液压锥形连接方式,并就该种连接方式的计算方法、技术难点进行详尽分析介绍,为今后类似设计提供一些参考。
