BEVEL GEAR ASSEMBLE AND ADJUSTMENT
1. Follower bevel gear assembly and adjustment
Follower bevel gear and bearing assembly complex. Assembly, the first beari-ng seat outside the circle painted machine bearing oil into the hole, after the beari-ng inner ring will be pressed into journal so that the Department close to the big
gear, painted with oil, will take the initiative to gear into the bearing cone, follow-ed by fitted with gaskets to adjust, the former bearing inner ring, gaskets, flanges,
flat washer, and finally installed in accordance with the provisions of Slotted Nut
Slotted nut tightening torque. Active degrees bevel gear bearing preload adjustment. Bevel gear assembly quality initiative good or bad, the key is to take the initiative to predegree cone gear bearings whether it is suitable to take the initiative to the main bevel gear reducer bearing pretightening same adjustments are an increase or decrease the use of the two frontend between the tapered roller bearing of the adju-sted to achieve the thickness of shim adjustment. Evaluation of active bearing pretightening degree bevel gear is appropriate, usually to take the initiative to bevel gearbearing shell loaded with complex, nonloaded oil seal, and a certain tightening torq-ue trough flange nuts, nut in the tightening should be tightened while edge Bearingshell rotation, so that roller bearings with outer ring in a proper position, in the ca-se of lubrication ministries, according to laps clockwise rotation, the measurement
of the initiative of the bevel gear bearing rotating torque to determine the suitabilityof predegree. Measurement method is that the shell bearings tiger caught in the pin-cers of Taiwan, and with the spring, said hook holes in the flange edge, along the tangent direction of said pulling spring. Measurement of rotating shaft bevel gear n-eeded to take the initiative to pull the size, take the initiative to rally the necessaryaxis should be consistent with the original, if the pulling force greater than the spe-cified value should be increased between the first two bearing adjustment shim thic-kness, tension should be reduced less than the specified value adjust the thickness of the gasket to adjust to the pass so far.
2.Owners, the driven bevel gear meshing with the meshing clearance checks
imprinted with the adjustment.
Lord, the driven bevel gear meshing of the check mark. Driven bevel gear b-earing predegree, after a good tune, good tune to take the initiative into the main
bevel gear reducer shell assembly. Attention when installed in the appropriate place between the two joints to adjust the thickness of the gasket, in accordance with the provisions of the fixed bolt tightening torque, and then coloring in the circumstan-ces, nonload the main bevel gear meshing driven situation. Inspection, the first driv-en bevel gear in 120 degrees of adjacent three teeth each from 2-3 in the tooth su-rface coated with thin uniform Hongdan oil, and then to the driven bevel gearresistance, rotating cone initiative bevel gear driven gear to drive laps, and then stopped to observe the follower bevel gear on the pressure of the blot, with the original r-equest. Lord, the driven bevel gear meshing clearance method. Inspection, first dial indicator fixed seat, so that contact dial indicator perpendicular to the driven bevel gear on the big end of the convex resist, table for zero, take the initiative to hand bevel gear fixed, and the other hand gently push back and forth driven bevel gear, the list of indicators by which the value of their engagement gap. Imprinted mesh
correct. Imprinted mesh design of the factory have a clearly defined, you can refer to the use of manuals, Western engagement in the teeth located in the central recta-ngle Xiaoduan bias away from the edge of Xiaoduan 2 4mm, high gear is located
in the central direction of bias from the tooth tip 0.8 -1.6mm, mesh gear is negative imprinting seek the same adjustment, if there are contradictions between the two should be a positive engagement, but the negative to ensure that the principle can work properly, otherwise there should be gear grinding or replacement. Lord, the d-riven bevel gear meshing blot, mesh gap adjustment. Lord, the driven bevel gear
meshing and mesh imprinting of the adjustment is the use of space to change the
center distance of two gear assembly to achieve in changing the mating contacts at Western will also change in space, they are interrelated and mutually contradictory, in the adjustment often occur when the value of space to meet the requirements,
the provisions do not conform to Western society. Tooth surface as a result of Western contact with the good or bad, is to determine tooth contact area, the assembly centers, such as distance and profile is an important basis to meet the requirements.Therefore, when imprinted with the meshing engagement gap adjustment of disputes,conflicts mesh imprinting is the major aspects of Western engagement should ensurethat the main gap may be more appropriate to enlarge, but not more than its limit,adjusting the methods for simplifying the formula: " Dajin from small out from the,into the main items, the main root. " If contact with the driven bevel gear in the
imprinting of the big-time, should be driven bevel gear bevel gear to take the initiative by the disturbance, if the meshing of space, therefore too small bevel gear can take the initiative to move out, when in contact with Western follower Xiaoduan
bevel gear, the driven bevel gears should be adjusted to take the initiative to leave the bevel gear. If the gap arising from the meshing is too large, can take the initiative to move inward bevel gear. When exposed to Western in the top of the drivenbevel gear, it will take the initiative to adjust the bevel gear to the bevel gear driven by the disturbance, so the meshing of smaller gap can be adjusted from the dynamic relocation of bevel gears, when the driven cone in contact with Western when the roots of gear, bevel gear can be adjusted to take the initiative to leave the fo-llower bevel gear, and if this result is too large gap meshing gears, bevel gears can be adjusted from moving inward movement. Twostage in the adjustment of the m-ain reducer, and the main follower bevel gear meshing and mesh imprinting gap di-fferential after adjustment should be carried out. Adjustment, simply adjust the diff-erential bearing caps at both ends of the ring nut, in order not to change the diffe-rential bearing preload, the adjustment to make the main, is driven cylindrical gear on, and the whole long tooth meshing, the meshing clearance checks should be 0.1-0.7mm, the maximum should not exceed 1mm.
圓錐齒輪的裝配和調(diào)整
1.從動(dòng)圓錐齒輪的裝配與調(diào)整
從動(dòng)圓錐齒輪的裝復(fù)。將軸承內(nèi)圈壓到中間軸軸頸上，涂上機(jī)油，將鉚好從動(dòng)齒輪的中間軸裝入主傳動(dòng)器中殼體內(nèi)，將軸承外圈壓入側(cè)蓋，先按分解記錄的調(diào)整墊片數(shù)量分別用螺栓套在左右側(cè)蓋上連側(cè)蓋一起裝上，注意側(cè)蓋與主減速器接合面處應(yīng)加密封墊，靠近從動(dòng)圓錐齒輪一側(cè)調(diào)整墊片可適當(dāng)厚些，以防下一步調(diào)齒輪嚙合問(wèn)隙時(shí)齒隙過(guò)小而卡住，按規(guī)定力矩?cái)Q緊左右側(cè)蓋固定螺栓。從動(dòng)圓錐齒輪軸承預(yù)緊度的調(diào)整。從動(dòng)圓錐齒輪軸承預(yù)緊度的檢查方法，用百分表測(cè)量，測(cè)量時(shí)將百分表固定于主減速器殼上，表觸頭抵住從動(dòng)錐齒輪的背面，左右撬動(dòng)從動(dòng)錐齒輪，表上所指最大與最小數(shù)值之差即為軸向移動(dòng)量，一般應(yīng)不大于0．05mm，最大不得超過(guò)O．10mm。檢查時(shí)，如果軸向間隙值大于規(guī)定，則減少任意一邊側(cè)蓋下調(diào)整墊片的厚度，如若軸向間隙小于規(guī)定值或轉(zhuǎn)動(dòng)從動(dòng)錐齒輪阻滯不靈活，則應(yīng)增加任一邊測(cè)蓋下調(diào)整墊片的厚度，直至檢查合格為止。
2.主、從動(dòng)錐齒輪嚙合印跡與嚙合間隙檢查與調(diào)整
主、從動(dòng)錐齒輪嚙合印痕的檢查。從動(dòng)錐齒輪軸承預(yù)緊度調(diào)好之后，把調(diào)好的主動(dòng)錐齒輪總成裝入主減速殼內(nèi)。注意裝時(shí)，在兩接合面間放適當(dāng)厚度的調(diào)整墊片，用螺栓固定并按規(guī)定力矩?cái)Q緊，然后用涂色法在無(wú)負(fù)荷情況下檢查主從動(dòng)錐齒輪嚙合情況。檢查時(shí)，首先在從動(dòng)錐齒輪相鄰120度三處每處取2-3輪齒，在齒面薄而均勻的涂上紅丹油，然后對(duì)從動(dòng)錐齒輪略施阻力，轉(zhuǎn)動(dòng)主動(dòng)錐齒輪帶動(dòng)從動(dòng)錐齒輪轉(zhuǎn)幾圈，然后停止下來(lái)，觀察從動(dòng)錐齒輪上壓出的印跡，是否符合原廠要求。主、從動(dòng)錐齒輪嚙合間隙的檢查方法。檢查時(shí)，首先將百分表座固定，使百分表觸頭垂直于從動(dòng)錐齒輪大端的凸面上抵住，表針對(duì)零，手握主動(dòng)錐齒輪不動(dòng)，另一手輕輕來(lái)回推動(dòng)從動(dòng)錐齒輪，表上所指示數(shù)即為其嚙合問(wèn)隙值。正確的嚙合印跡。嚙合印跡各制造廠設(shè)計(jì)時(shí)都有明確規(guī)定，可以參閱使用說(shuō)明書(shū)，嚙合印跡在齒長(zhǎng)方位于中部偏向小端，距小端邊緣2 4mm，齒高方向位于中部偏向齒項(xiàng)距齒頂0．8-1．6mm，齒輪正反面嚙合印跡力求一致，調(diào)整時(shí)，如果二者有矛盾應(yīng)以正面嚙合為主，但反面要保證能正常工作為原則，否則應(yīng)進(jìn)行修磨或更換齒輪。主、從動(dòng)錐齒輪嚙合印跡，嚙合間隙調(diào)整。主、從動(dòng)錐齒輪嚙合印跡和嚙合間隙的調(diào)整都是利用改變兩齒輪裝配中心距來(lái)實(shí)現(xiàn)的，在改變接觸印跡時(shí)嚙合間隙也會(huì)隨之變化，它們是相互聯(lián)系又相互矛盾的，在調(diào)整時(shí)往往會(huì)出現(xiàn)間隙值符合要求，印跡卻不符合規(guī)定的矛盾。由于齒面接觸印跡的好壞，是判斷齒面接觸面積，裝配中心距離和齒形等是否符合要求的重要依據(jù)。因此，當(dāng)嚙合印跡與嚙合間隙調(diào)整中出現(xiàn)矛盾時(shí)，嚙合印跡是矛盾的主要方面，應(yīng)保證嚙合印跡為主，間隙可適當(dāng)放大些，但也不得超其極限值，調(diào)整方法簡(jiǎn)化口訣為：“大進(jìn)從，小出從，項(xiàng)進(jìn)主，根出主”。若接觸印跡在從動(dòng)錐齒輪的大端時(shí)，應(yīng)將從動(dòng)錐齒輪向主動(dòng)錐齒輪靠擾，假如因此而使嚙合間隙過(guò)小，可將主動(dòng)錐齒輪向外移動(dòng)，當(dāng)接觸印跡在從動(dòng)錐齒輪小端時(shí)，應(yīng)將從動(dòng)錐齒輪調(diào)整使其離開(kāi)主動(dòng)錐齒輪。若因此而出現(xiàn)嚙合間隙過(guò)大，可將主動(dòng)錐齒輪向內(nèi)移動(dòng)。當(dāng)接觸印跡在從動(dòng)錐齒輪的頂端時(shí)，將主動(dòng)錐齒輪調(diào)整向從動(dòng)錐齒輪靠擾，因此而使嚙合間隙變小，可將從動(dòng)錐齒輪調(diào)整外移，當(dāng)接觸印跡在從動(dòng)錐齒輪根部時(shí)，可將主動(dòng)錐齒輪調(diào)整，使其離開(kāi)從動(dòng)錐齒輪，如果因此而使齒輪嚙合間隙過(guò)大，可將從動(dòng)錐齒輪調(diào)整向內(nèi)移動(dòng)。雙級(jí)主減速器在調(diào)整好，主從動(dòng)錐齒輪嚙合印跡和嚙合間隙之后還應(yīng)進(jìn)行差速器調(diào)整。調(diào)整時(shí)，只需調(diào)整差速器軸承蓋兩端的環(huán)形螺母，為了不改變差速器軸承預(yù)緊度，調(diào)整使主、從動(dòng)圓柱齒輪對(duì)正，并全齒長(zhǎng)嚙合，嚙合間隙檢查應(yīng)在O.1-0.7mm，最大不得超過(guò)1mm。
