Make one line as figure 3 to decide the zero point and the length l0. 3. 压装 Assembly 3.1  打开A阀，启动轴向、径向手动泵开始压装，压装过程中应注意径向油压不可上升过快，以免漏油。 Open A valve ,start the axial/radial pump to push up rudder stock, the radial pressure don’t raise too fast to avoid the oil leakage during assembly. 3.2 在轴向及径向同时加压使之将锥度压入长度至12.0mm 。压入力估算值轴向为650-690bar, 径向为670-710bar。装配时以压入距离为准，压入力仅做参考。但不要超过最大的涨毂压力。在加压过程中对每推进1mm压入长度做记录。 Raise the axial & radial pressure to push-up length 12mm .axial pressure is about 650-690bar , radial pressure is about 670-710bar .the push up distance is important for operation and the pressure is only for reference  during assembly .but don’t exceed the max. widening pressure .record the pressure with each 1mm push up distance. 3.3关闭A阀，百分表不动，泄掉径向压力，30分钟后若百分表读数无变化，泄掉轴向油压。 Shut off A valve to release the radial pressure . if the reading of dial guage don’t change ,release the axial pressure . 3.4拆除百分表、软管、液压泵； Remove the dial guage 、hose 、hydraulic pump 3.5上紧螺母 ，安装螺母止动条。止动条尺寸为220x30x700mm 。 Tighten the hydraulic nut and install the securing bar .the securing bar dimensions is 220x30x700mm . 五、舵杆与舵柄船上安装： Installing the rudder stock & tiller on board 舵杆与舵柄按制造厂所示标记在船上进行安装。 Rudder stock & tiller assembly on board according to the mark of the maker made 1. 压装准备 Prepare for assembly 1. 1认真检查液压螺母的螺纹及舵杆螺纹，如有硬伤、飞刺及高点等缺陷，应用        油石进行仔细修研直至螺纹表面光顺为止； Checking the screw of hydraulic nut & rudder stock ,if having scrape 、 edge sharp 、ridge etc., we should grind the screw smoothly by using hone 1. 2将舵柄锥孔及舵杆锥体部位进行彻底的清洁； Cleaning the cone hole of tiller and taper part of rudder stock throughly 1. 3吊舵柄至舵杆上，将其推靠； Lifting the tiller to the rudder stock 1. 4将液压螺母和舵杆螺纹清洁好并喷涂适量MoS2润滑剂，然后将液压螺母吊装到舵杆上，并旋紧； Cleaning the hydraulic nut and the screw of rudder stock , apply any MoS2 on the screw and lift the hydraulic nut to the rudder stock and tighten it . 1.5 按示意图一安装轴/径向液压泵及其软管； Installing the axial/radial direction hydraulic pump and hose according to attached drawing 1.6 排除液压系统中的空气。 Remove the air of the hydraulic system 2．舵柄安装（参见示意图二及示意图三） Tiller assembly ( see attached drawing 二 and drawing 三) 2. 1“0”位确定(与舵杆“0”位确定相同) Decide the “0” point (same as deciding the zero point for rudder stock) 2.2 压装（参见示意图二）。Assembly (see attached drawing 二 )。 a. 打开A阀，在轴向及径向同时加压使之将锥度压入长度至9.5 mm（参见示意图三），压入力估算值4305KN。装配时以压入距离为准，压入力仅做参考。在加压过程中对每推进1mm压入长度做记录。 Open the A valve , raise the axial / radial pressure at the same time until the push-up length to the 9.5 mm (see attached drawing 三) the pressure is about 4305KN .the push-up distance is important ,the pressure is only a reference value ,record the push-up distance with each 1mm during the assembly 继续阅读
