Made by Shuangzheng Machinery: Three Row Roller Slewing Bearing For Tunneling Shield Machine
The three-row roller type slewing bearing has three races, and the upper and lower and the radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can withstand various loads at the same time, and it is the one with the largest bearing capacity among many products. The shaft and radial size are large and the structure is firm, which is especially suitable for heavy machinery requiring large diameter.
The basic working principle of the shield machine is that a cylindrical steel component is pushed forward along the axis of the tunnel to excavate the soil. The housing of the cylindrical assembly is a shield that temporarily supports the excavated unlined tunnel section, withstands the pressure of the surrounding soil layer, and sometimes withstands groundwater pressure and blocks the groundwater. Excavation, earthmoving, lining and other operations are carried out under the cover of the shield.
The working conditions are complex, so the requirements for the slewing bearing are relatively high. The slewing bearings used on the general shield machine are all three rows of rollers.
