舵和螺旋桨0.docx

7舵和螺旋桨构造(RudderandScrewPropeller)舵和螺旋桨是船舶的重要操纵设备。舵的作用是改变船的航向，螺旋桨的作用是产生推动船前进的动力。7.1各种类型舵的结构图7.1.1舵的类型typesofrudder(I)半平衡舵semi-balancedrudder(II)悬挂舵spaderudder(III)多支承舵multi-pintlerudder(IV)三支点平衡舵threebearingbalancedrudder(V)穿心舵轴平衡舵penetratingspindlebalancedrudder（I）（II）（III）（IV）（V）图7.1.1舵的类型图7.1.2平板舵结构(不平衡舵)singleplateruddereq\o\ac(○,1)上舵杆upperrudderstockeq\o\ac(○,2)连接法兰jointflange,couplingflangeeq\o\ac(○,3)上舵销upperrudderpintleeq\o\ac(○,4)舵钮ruddergudgeon,rudderbraceeq\o\ac(○,5)舵臂rudderarmeq\o\ac(○,6)中舵销intermediaterudderpintleeq\o\ac(○,7)下舵杆lowerrudderstockeq\o\ac(○,8)舵板rudderplateeq\o\ac(○,9)下舵销lowerrudderpintleeq\o\ac(○,1)eq\o\ac(○,2)eq\o\ac(○,3)eq\o\ac(○,4)eq\o\ac(○,5)eq\o\ac(○,6)eq\o\ac(○,7)eq\o\ac(○,8)eq\o\ac(○,9)图7.1.2平板舵结构图7.1.3流线型舵结构（平衡舵）streamlinedrudderconstructioneq\o\ac(○,1)舵杆rudderstockeq\o\ac(○,2)舵面板ruddersurfaceplateeq\o\ac(○,3)水平肋板horizontalflooreq\o\ac(○,4)焊接衬板weldbackingeq\o\ac(○,5)垂直舵板verticalrudderplateeq\o\ac(○,1)eq\o\ac(○,2)eq\o\ac(○,3)eq\o\ac(○,4)eq\o\ac(○,5)图7.1.3流线型舵结构图7.1.4流线型舵装置streamlinedruddergeareq\o\ac(○,1)舵杆rudderstockeq\o\ac(○,2)吊环眼hoistingringeyeeq\o\ac(○,3)舵顶板ruddertopplateeq\o\ac(○,4)水平法兰接头horizontalflangejointeq\o\ac(○,5)垂直法兰接头verticalflangejointeq\o\ac(○,6)上舵轴衬套upperrudderaxlesleeve(liner)eq\o\ac(○,7)上轴承upperbearingeq\o\ac(○,8)舵面板ruddersurfaceplateeq\o\ac(○,9)中间舵轴衬套middlesleeve(liner)eq\o\ac(○,10)横向肋板transverseflooreq\o\ac(○,11)下舵轴衬套lowerrudderaxlesleeve(liner)eq\o\ac(○,12)下轴承lowerbearingeq\o\ac(○,13)衬套sleeve,linereq\o\ac(○,14)舵轴承座rudderaxlesupporteq\o\ac(○,15)舵底板rudderbottomplateeq\o\ac(○,16)竖向肋板verticalflooreq\o\ac(○,17)舵底塞plugeq\o\ac(○,18)舵轴rudderaxleeq\o\ac(○,19)圆螺母circularnuteq\o\ac(○,1)eq\o\ac(○,5)eq\o\ac(○,2)eq\o\ac(○,3)eq\o\ac(○,4)eq\o\ac(○,6)eq\o\ac(○,7)eq\o\ac(○,8)eq\o\ac(○,9)eq\o\ac(○,10)eq\o\ac(○,11)eq\o\ac(○,12)eq\o\ac(○,13)eq\o\ac(○,14)
