1) The assembly and adjustment of the bearings 27310 and 27311 on the driving spiral bevel gear shall in SINOTENG loaders meet the following requirements:
Under the condition that the driving spiral bevel gear is not meshed and not equipped with the oil seal and the oil seal cap, adjust the spacer in a gradually thinning method so that the castle nut is hooked into the assembly hole of the input flange with the tension meter under the locking force of 35-40 kg·m. Pull the tension meter toward the tangent direction so that the reading of the tension meter is 4-5 kg when the input flange begins to rotate. The castle nut need the locking force of 35-40 kg·m during final assembly.
2) The assembly distance of the spiral bevel gear must be adjusted to be correct to ensure that the gear is correctly meshed. The contact surface and the correct gear side clearance can be achieved by adjusting the nut and the spacer. The meshing of the driving and driven spiral bevel gears shall be inspected in a staining method. The contact spot is about 30%-50% along the gear length, 50% along the gear height and keeps the meshing clearance of 0.2-0.25 mm.
3) The meshing clearance between the half axle gear and the bevel gear of the differential is 0.1 mm to ensure that the half axle gear and the bevel gear can be rotated easily by hand without blocking.
4) The bearing 7515 is adjusted with the adjusting nut to ensure that the clearance is kept within 0.03-0.05 mm.
5) When repairing and replacing the wheel speed reducing gear, check the contact condition in a staining method, the contact spot is not less than 40% along the gear height and not less than 50% along the gear length. When replacing the planetary gear roller pin, match all roller pins in groups to ensure that the internal diameter allowance of the same group does not exceed 0.005 mm. The ellipticity and taper are smaller than 0.003 mm, and the radial fit clearance between the roller pin inner hole and the pin is 0.015-0.03 mm.
