一种船舶舵系间隙的测量方法
摘要：
本发明公开了一种船舶舵系间隙的测量方法，具体包括以下步骤：在舵叶的左、右两侧分别固定一个手拉葫芦；在舵叶的一个侧面上安装百分表；通过左侧的手拉葫芦拉动舵叶，当百分表读数不变时，读取百分表读数a；通过右侧的手拉葫芦拉动舵叶，当百分表读数不变时，读取百分表读数b；根据读数a和读数b，计算出舵系总间隙。本发明操作简单、使用方便，解决了舵杆筒衬套下方设置有阻水装置的船舶的舵系间隙无法测量的问题，本方法的测量误差小，测量数据精确。
摘要（英）：

The invention discloses a measurement method for a gap of a rudder system of a ship. The method concretely includes the following steps: respectively fixing a chain block on left and right sides of arudder blade; installing a dial indicator on one side surface of the rudder blade; pulling the rudder blade through the chain block on the left side, and reading a reading a of the dial indicator whena reading of the dial indicator does not change; pulling the rudder blade through the chain block on the right side, and reading a reading b of the dial indicator when the reading of the dial indicator does not change; and calculating a total gap of the rudder system based on the reading a and the reading b. The method has the advantages of simple operation and convenient usage, solves the problem that the gap of the rudder system of the ship provided with a water blocking device below a rudder trunk bushing cannot be measured, is small in measurement error, and is accurate in measurement data.
