Elastic cushion structure thrust bearing installation process

Thrust bearing installation process 2019 - elastic cushion structure 07 - Thrust bearing structure as shown in figure 15 elastic cushion structure: installation steps are as follows: ( 1) Thrust bearing for the elastic cushion support structure, under the frame of pit with high level requirements, so the frame in the pit pre-installed, frame thrust bearing surface level must be controlled under 0. 02 mm/m. （ 2) Formal when installation, gaskets and elastic cushion block is to install according to the drawing, and then put the elastic cushion standard parts. According to the number symmetry back thrust tile, check inside and outside and limit pin on both sides and thrust wazhou gap to meet the requirements of the drawings. （ 3) High precision level measuring each piece of tile flatness in 0. 02 mm/m, the maximum height allowed for all thrust tile surface error is 0. 05mm。 If overweight, according to the measured results calculated thrust tile tear the adjustment of the cushion thickness, hanging open needs adjustment of thrust tile. （ 4) The arrival of the goods of adjusting shim a total thickness of 3. 2 mm, the thickness of each piece of 0. 05mm。 Generally take step by step a tear of cushion thickness reduction pad, tear after can't stick back, so in the process of construction shall ensure the accuracy of the measurement data. （ 5) Back pack elastic cushion block, the elastic cushion and thrust tile, retest all thrust tile level should be zero. 02 mm/m, the maximum height allowed for all thrust tile surface error is 0. 05mm。 （ Source: mechanical and electrical craftsman)
