Rolling mill reducer lifting, transportation and installation

Page view
[Abstract]:
If R BBB 0 200mm is needed, the axial runout value can be increased accordingly.
7. Input and output shaft couplings must be installed in accordance with their standards. It is not allowed to force 
1. The lifting hole of the lower box body must be used when lifting the whole box, and the lifting hole of the upper box body shall not be used.
 
 
2. Gear box shall be placed horizontally during transportation and storage and fixed on the support.

 3. Do not drag and pull the gear box to avoid damage to the bottom surface. At the same time, do not drag, grab, pull and shake each oil pipe to avoid causing deformation and oil seepage of the oil pipe.

 
 
4. Sufficient stiffness is required for gear box mounting foundation, and there should be spacer under the box body, and the level of foundation mounting surface should be 0.05/1000(mm).
 
 
5. After the anchor bolts are tightened, check them near the bolts with a dial gauge. When the bolts are relaxed, the box body moves, indicating uneven foundation or incomplete gasket, which should be corrected.

 6. After adjusting the gear box level, the input shaft connected with the main motor must be concentric with the motor shaft when running. In order to meet this need, its axial and radial runout must be measured with a special measuring device, as shown in the figure below:

 If R BBB 0 200mm is needed, the axial runout value can be increased accordingly.7. Input and output shaft couplings must be installed in accordance with their standards. It is not allowed to force the coupling sleeve into the input and output shaft of the gear box, which will damage the bearing and other parts of the input and output shaft system. Coupling shaft sleeve heating rooms must be set on the input and output shaft of the gear box, to control the heating temperature not over 200 ℃, when baking set to measure the size of the match first, whether there is enough clearance, avoid set the temperature drop and jammed half; At the same time, pay attention to the input and output oil seal (if there is) cooling protection, otherwise the oil seal under thermal deformation will lead to oil leakage.
