1、附录A：BEVEL GEAR ASSEMBLE AND ADJUSTMENT1. Follower bevel gear assembly and adjustmentFollower 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
2、 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 tig
3、htening 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 adjustme
4、nts 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 w
5、ith 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
6、, 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 p
7、ulling 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 adj
8、ustment 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 ma
9、rk. 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 fixe

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 be
11、vel 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 c
12、ontact 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. Imprinte
13、d 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
14、 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 ge
15、ar 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 c
16、ontradictory, 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
