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.

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

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

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.

从动圆锥齿轮的装复。将轴承内圈压到中间轴轴颈上，涂上机油，将铆好从动齿轮的中间轴装入主传动器中壳体内，将轴承外圈压入侧盖，先按分解记录的调整垫片数量分别用螺栓套在左右侧盖上连侧盖一起装上，注意侧盖与主减速器接合面处应加密封垫，靠近从动圆锥齿轮一侧调整垫片可适当厚些，以防下一步调齿轮啮合问隙时齿隙过小而卡住，按规定力矩拧紧左右侧盖固定螺栓。从动圆锥齿轮轴承预紧度的调整。从动圆锥齿轮轴承预紧度的检查方法，用百分表测量，测量时将百分表固定于主减速器壳上，表触头抵住从动锥齿轮的背面，左右撬动从动锥齿轮，表上所指最大与最小数值之差即为轴向移动量，一般应不大于0．05mm，最大不得超过O．10mm。检查时，如果轴向间隙值大于规定，则减少任意一边侧盖下调整垫片的厚度，如若轴向间隙小于规定值或转动从动锥齿轮阻滞不灵活，则应增加任一边测盖下调整垫片的厚度，直至检查合格为止。　　

主、从动锥齿轮啮合印痕的检查。从动锥齿轮轴承预紧度调好之后，把调好的主动锥齿轮总成装入主减速壳内。注意装时，在两接合面间放适当厚度的调整垫片，用螺栓固定并按规定力矩拧紧，然后用涂色法在无负荷情况下检查主从动锥齿轮啮合情况。检查时，首先在从动锥齿轮相邻120度三处每处取2-3轮齿，在齿面薄而均匀的涂上红丹油，然后对从动锥齿轮略施阻力，转动主动锥齿轮带动从动锥齿轮转几圈，然后停止下来，观察从动锥齿轮上压出的印迹，是否符合原厂要求。主、从动锥齿轮啮合间隙的检查方法。检查时，首先将百分表座固定，使百分表触头垂直于从动锥齿轮大端的凸面上抵住，表针对零，手握主动锥齿轮不动，另一手轻轻来回推动从动锥齿轮，表上所指示数即为其啮合问隙值。正确的啮合印迹。啮合印迹各制造厂设计时都有明确规定，可以参阅使用说明书，啮合印迹在齿长方位于中部偏向小端，距小端边缘2 4mm，齿高方向位于中部偏向齿项距齿顶0．8-1．6mm，齿轮正反面啮合印迹力求一致，调整时，如果二者有矛盾应以正面啮合为主，但反面要保证能正常工作为原则，否则应进行修磨或更换齿轮。主、从动锥齿轮啮合印迹，啮合间隙调整。主、从动锥齿轮啮合印迹和啮合间隙的调整都是利用改变两齿轮装配中心距来实现的，在改变接触印迹时啮合间隙也会随之变化，它们是相互联系又相互矛盾的，在调整时往往会出现间隙值符合要求，印迹却不符合规定的矛盾。由于齿面接触印迹的好坏，是判断齿面接触面积，装配中心距离和齿形等是否符合要求的重要依据。因此，当啮合印迹与啮合间隙调整中出现矛盾时，啮合印迹是矛盾的主要方面，应保证啮合印迹为主，间隙可适当放大些，但也不得超其极限值，调整方法简化口诀为：“大进从，小出从，项进主，根出主”。若接触印迹在从动锥齿轮的大端时，应将从动锥齿轮向主动锥齿轮靠扰，假如因此而使啮合间隙过小，可将主动锥齿轮向外移动，当接触印迹在从动锥齿轮小端时，应将从动锥齿轮调整使其离开主动锥齿轮。若因此而出现啮合间隙过大，可将主动锥齿轮向内移动。当接触印迹在从动锥齿轮的顶端时，将主动锥齿轮调整向从动锥齿轮靠扰，因此而使啮合间隙变小，可将从动锥齿轮调整外移，当接触印迹在从动锥齿轮根部时，可将主动锥齿轮调整，使其离开从动锥齿轮，如果因此而使齿轮啮合间隙过大，可将从动锥齿轮调整向内移动。双级主减速器在调整好，主从动锥齿轮啮合印迹和啮合间隙之后还应进行差速器调整。调整时，只需调整差速器轴承盖两端的环形螺母，为了不改变差速器轴承预紧度，调整使主、从动圆柱齿轮对正，并全齿长啮合，啮合间隙检查应在O.1-0.7mm，最大不得超过1mm。
