1. Install

Typically inner and outer rings inseparable radial bearings, inner ring and the shaft often using relatively tight fit; the outer ring and housing bore is used relatively loose fit. Available at this time the pressure will be pressed on the shaft bearing, and then together with the shaft bearing load bearing hole. When the press-fit assembly adopted a sleeve made of soft metal such as copper or soft steel can be. Shaft diameter slightly larger than the inner diameter of the sleeve, an outer diameter slightly smaller than the bearing inner wall. When load the shaft and the bearing seat must hole between the sleeve and the bearing end faces plus a plate simultaneously. Pore ??size slightly larger than the shaft diameter, an outer diameter slightly smaller than the outer diameter of the bearing. Its role is to prevent the bearing outer ring deflection or jammed seat hole. Pressure exerted on the sleeve may be mechanical, but also hydraulic. But definitely not directly hammer ring face. Because the rings belong hardened thin-walled parts, hammering easy to produce surface cracks.

2. heating installation

Installation interference rings and bearing the force required to increase the size and amount of interference with the size. For large amount of interference, the large bearings, often using heating installation methods. Before the thermal loading of the bearing into the tank uniformly heated to 80 ℃ ~ 100 ℃, then remove from the oil onto the shaft. Bearings should not be placed on the bottom when heated to prevent precipitation of impurities into the bearing. And should strictly control the oil temperature must not exceed 100 ℃. The bearing batch size can also use other electrical heating methods such as induction heaters, electric hot plate and electric furnace.

3. Remove

Removing the inner ring and the shaft tight fit, loose outer ring and housing bore bearings can not be separated, the first shaft together with the bearing removed from the bearing hole, and then remove the bearing from the shaft. Removing the inner and outer rings separable bearings, first remove the shaft together with the inner ring, the inner ring and then remove it from the shaft; the outer ring from the bearing hole split out. Remove the bearing from the shaft to remove the shaft or the bearing inner ring by the press are available. Screw mechanism can also be used. When the outer ring of the seat hole with a tight, pressure mechanism available to press out the outer ring.
