Government's roller press cone bearing installation

1, for cone bearing and taper is commonly large taper 1:12 and small 1:30 taper two kinds, the first test and bearing, bearing the vertical lift, cooperate on the taper shaft, slowly taper shaft with red lead powder in advance along the axial daub a few test mark, and then put the bearing left, observe the red lead powder contact traces, ensure contact area over 75%, otherwise the grinding shaft until matching area is reached. 2, continuing with cone bearing, install the bearing to the shaft, measure the bearing inner end face with roller press roll body size of shoulder, need accurate measurement, use block gauge and feeler, circumferential direction measurement for 4 points, take the average hypothesis for R. Because between bearing the inside end face and roll shaft shoulder need to have a seal ring in the actual assembly, width is r, so you need to grinding spacer ring width, and relationship between r = r - A, in which a is axial advance amount. 3, axial push a need to conform to the technical requirement schedule. 4, will be in a bearing seat, bearing assembly on the taper shaft bearing assembly, through the bearing outer end and shaft gland the step size to measure the axial amount of advance, the advance amount is also a value (above The axial advance amount) 。 5, ensure the bearing axial type a propulsion in place, the inside of the bearing and seal ring insulation clingy together, and the inner ring expansion volume and the rest of the clearance in line with the government's recommended value.
