輪舵機(jī)修理工藝(附圖)

1、mv *procedure specification of steering gear repair 1，修理前先進(jìn)行舵機(jī)運(yùn)轉(zhuǎn)試驗(yàn)檢查運(yùn)動(dòng)部件的運(yùn)行情況。before repair, we will do the steering gear running test to check the running condition.2，進(jìn)塢后先測(cè)量上下舵鈕的間隙，上舵承間隙測(cè)量，數(shù)據(jù)記錄。舵桿與舵葉聯(lián)接平面檢查，緊配螺栓檢查，確定舵桿與舵葉的聯(lián)接情況。測(cè)量重磅平面至撞桿柱塞中心線的高度數(shù)據(jù)記錄。測(cè)量撞桿柱塞與十字頭的間隙a、b兩位置。測(cè)量舵葉與假舵的間隙c、d兩位置。測(cè)量舵桿中心至撞桿柱塞銷(xiāo)的距

2、離。（如圖1）.after drydocking, measure and record rudder pintles clearances and rudder carrier clearances, check the condition of flanges & bolts that connect rudder stock and rudder blade to know how about the connection, measure and record the distance between ram center line and foundation flange surf

3、ace, measure and record upper clearance & lower clearance ab between ram and tiller fork, measure and record the jumping clearances cd, measure and record the distance between rudder stock center line and ram pin.圖1. 原始數(shù)據(jù)測(cè)量示意圖 (drawing for measurement)3，拆除上下舵鈕，拆除舵桿與舵葉平面聯(lián)接緊配螺栓。舵葉吊離船體放妥。dismantle rudd

4、er pintles, and dismantle the bolts connecting rudder stock flange and rudder blade flange, then lift rudder blade away.4，拆除轉(zhuǎn)舵十字頭，拆除轉(zhuǎn)舵軸承總成。測(cè)量舵桿軸徑，軸承直徑，檢查平面軸承的貼合面，平面軸承包扎好吊車(chē)間放妥。dismantle rudder tiller and ruuder carrier assembly, measure and record the diameters of rudder stock and rudder carrier bush

5、, check the condition of plane bearing, then pack the plane bearing and transport it to workshop.5，塢修鉗工用拉線方法測(cè)量假舵上平面至重磅法蘭底座的距離允許誤差1mm。measure and record the distance between upper surface of rudder horn and foundation flange by drawing wire, allowed error is within 1mm.6，輪機(jī)鉗工測(cè)量左、右液缸柱塞與壓緊密封函法蘭的間隙數(shù)據(jù)記錄。

6、以四周壁拉出液缸柱塞的十字線。measure and record clearance between rams (both sides) and stuffing flanges. to position 4 reference points on 4 sides wall by drawing wire, and mark them, that will be used for positioning the steering gear when refit them later.7，轉(zhuǎn)舵液缸地座前割除前，必須進(jìn)行加強(qiáng)用。133mm的管子，橫向燒焊加強(qiáng)。before cutting the

7、 steering gear with its foundation frames (both sides), we will weld pipes (dia, 133mm) to the both sides frames to strengthen the whole set to prevent deformation.8，轉(zhuǎn)舵液缸底座焊縫烊掉后，輪機(jī)鉗工復(fù)測(cè)左、右液缸柱塞與壓緊密封函法蘭的間隙前后數(shù)據(jù)比對(duì)。轉(zhuǎn)舵液缸總成連底座一起移至船體可施工即可。after cutting the steering gear with frames, measure and record cleara

8、nce between rams (both sides) and stuffing flanges again, compare these new data with that of point 6. the steering gear with frames will be removed aside until we have enough space to do the steel job.9，船體可以進(jìn)行舵承甲板換板工程。并新制平面軸承重磅法蘭底座。now we will start the deck plate renewal, and fabricate new foundat

9、ion flange.10，通過(guò)拉線初步確定重磅法蘭底座的位置，應(yīng)考慮法蘭平面的機(jī)加工的切削余量加上先前測(cè)量的重磅平面至撞桿柱塞中心線的高度及a、b兩點(diǎn)的間隙及舵葉與假舵的間隙c、d兩位置數(shù)據(jù)，通過(guò)分析計(jì)算最后確定高度。拉線方法可以把上下舵鈕作為基準(zhǔn)參照，但前提條件是上下舵鈕軸承不能磨損太多，否則就要破壞軸承以本體孔為標(biāo)準(zhǔn)。正確的拉線方法是以尾軸中心線為基準(zhǔn)點(diǎn)過(guò)上下舵鈕中心引上去的一根直線。（根據(jù)具體情況再確定）do calculation according to data of point 2 and point 5, we will position the new foundation

10、 flange roughly by drawing wire, and we can ascertain processing margin of new foundation flange and final distance between ram center line and foundation flange surface. if the condition of pintles bushes is available, we can consider pintles as benchmark to draw wire, otherwise we have to take the

11、 houses of pintles bushes as benchmark. the right way for alignment is to take the cross point of tailshaft center line and the pintle holes center line as benchmark to draw wire upwards. ( we will do it on spot).11，重磅法蘭底座初定位后，船體可進(jìn)行施焊，要盡量減少施焊所造成的變形。after position the foundation flange roughly, we wi

12、ll start the welding job, and will do our best to reduce deformation.12，施焊工程結(jié)束后，機(jī)加工鏜重磅法蘭底座平面，保證法蘭平面與舵桿理論線相垂直，同時(shí)平面與撞桿柱塞的中心線高度應(yīng)該是初定位時(shí)計(jì)算的高度減去加工的切削量。（如圖2）after welding, we will machine the flange surface plumb to the rudder stock center line, after deduct the processing margin, we will ascertain the fin

13、al distance between ram center line and foundation flange surface as mentioned in point 10.圖2. 底座法蘭示意圖 (drawing for rudder carrier foundation flange)13，裝上平面軸承調(diào)整平面軸承，按照舵桿理論線調(diào)整平面軸承座的位置，使舵桿上軸承孔與上下舵鈕孔在同心位置，并用非緊配螺絲4個(gè)進(jìn)行固定。用角尺檢查平面軸承與理論線的垂直度。refit the ruuder carrier assembly, and adjust its positon accordin

14、g to the rudder stock center line to make the center of rudder carrier be at the same line with the centers of upper and lower pintles. then temporarily fix rudder carrier asembly to foundation flange using bolts in clearance fit, and check verticality of plane bearing and rudder stock center line.1

15、4，對(duì)稱打上定位銷(xiāo)確定平面軸承座位置，并按照平面軸承座孔劃線，移除軸承座，進(jìn)行鉆孔。if everything is ok, we will symmetrically fit position pins to fix the rudder carrier, and mark the foundation bolts position, then remove the ruuder carrier assembly, and drill holes on foundation flange according to the marks.15，軸承座地腳螺栓孔鉸制配緊配螺栓。軸承座裝復(fù)。（如圖3

16、）finally finish the holes and fabricate new bolts of interferencefit, then refit the ruuder carrier assembly.圖3. 軸承座安裝示意圖 (drawing for installment)16，裝復(fù)舵桿、舵葉。測(cè)量上、中、下三個(gè)軸承的間隙，平面軸承進(jìn)行藍(lán)油著色試驗(yàn)要求貼合面積大于90%以上。refit rudder stock & rudder blade, measure rudder pintles clearances and rudder carrier clearances ag

17、ain. dye check the plane bearing with blue oil, touched area should be more than 90% of total area.17，轉(zhuǎn)舵液缸總成連底座的定位，根據(jù)舵桿的十字中心及先前所測(cè)量的重磅法蘭底座至撞桿中心線、舵桿中心至撞桿柱塞銷(xiāo)的數(shù)據(jù)，進(jìn)行調(diào)整定位。（如圖4）to position the steering gear with frames according to data of point 2, point 5, point 10. 圖4. 撞桿定位示意圖18，施焊前鉗工要測(cè)量左、右液缸柱塞與壓緊密封函法蘭的間隙，或在左、右柱塞液缸上放百分表進(jìn)行觀察控制并延續(xù)到施焊工程結(jié)束。一經(jīng)發(fā)現(xiàn)有變化立即停止施焊通知技術(shù)部。 before welding, measure cle
