Question:

How are sliding bearings and rolling bearings assembled?

I mean, how do you install the large equipment? Can you tell me in detail?

Answer:

1, the sliding bearing assembly method:(1) the first to remove the sliding bearing assembly for sealing the protective rust agent (closed bearing installation, except) can use hydraulic method of bearing inner ring applied no impact loads will be fitted to the shaft bearing qualified bearing block, if there are no conditions can also use Pratia gently on bearing the inner ring is mounted, ordinary bearings allow color thermal sleeve method, but the heating temperature not exceeding 100 degrees, and the bearing should be relatively uniform for heating.(2) the sliding bearing assembly and bearing must be on the same plane, the same line, the same axis, the bearing must be parallel mutually in the same plane parallel to each other, and the corrected assembly gap, the parallelism and beat meets the design requirements, ensure the smooth sliding equipment.
First of all, rolling bearings are easy to slideRolling into the general bearing position to be in place.Large equipment, plain bearings, very precise. First painted look and the axis of the contact pressure is required to do according to the clearance bearing and shaft in general adjustment times.If you haven't done it, you'd better ask someone to do it. If your head once afraid not this kind of equipment is very expensive. The motor and the machine are to be connected by meter.Bearings are now generally not adjusted by scraping pads.
2, rolling bearing assembly method:(1) with copper or aluminum bar mat, hammer uniform light on the inner ring and the outer ring, the holder can not knock bearing.(2) made of mild steel or copper special sets of cushion, hammer light and uniform type.(3) when the interference fit is large, mechanical press assembly can be adopted. Usually performed on an oil press or a screw press.(4) the assembly of temperature difference is composed of the principle of expansion and contraction. The heating assembly is to heat the bearings in the oil at 80~100 degrees before the bearings are mounted on the shaft and then assemble them. It can also be cold assembled, and the bearings are placed in -40 - 50 industrial refrigerators or cooled with dry ice before the bearings are loaded into the housing.
