摘要
The present invention has an annular receiving space (110) , the bearing housing (11) having a first pitching protrusion (112) formed on the bottom surface (111) of the receiving space (110) ; The first pitch is provided to be seated on the projection 112,the first pitch of the projections can be of a lower leveling plate 12 is a state around the pitching 112; An upper leveling plate 13 disposed between the lower leveling plates 12 ; Being the second pitching projection 141 on a lower surface formed, and the second pitching projection 141 is the upper leveling plate and capable of installation doemeurosseo pitching to be secured to the 13 state, the one side formed with an oil supply port (143) The upper surface of the present invention relates to a thrust bearing for a reactor coolant pump, comprising a plurality of thrust shoes 14 having an annular oil groove 144 communicating with the oil supply port.;Moreover, this invention is the process of cut | disconnecting plate-shaped raw material in ring shape (step 1) ; Heat-treating the cut ring (step 2) ; Blasting to remove the oxide layer formed on the ring surface due to the heat treatment (step 3) ; Roughing the surface of the ring (step 4) ; Depositing a Babbitt layer on the use surface of the ring by gravity casting (step 5) ; Cutting the ring into segments ( step 6) ; Removing the babybit outside the use surface of the segment (step 7) ; Roughing the Babbitt layer of the segment (step 8) ; First step of checking the binding degree between the segment of the segment and the body of the segment (step 9 ) ; Finishing the Babbitt layer of the segment (step 10) ; And a second step of inspecting the degree of binding between the segment of the segment of the segment and the body of the segment (step 11) .;Thrust bearings for reactor coolant pump, self-leveling
