Cylindrical hole centripetal bearing loading and unloading steps

1. Install inner and outer ring usually inseparable centripetal bearings, inner ring and the shaft is often use a tight fit; A loose fit will be used on outer ring with a hole. Available at this time the pressure will first pressed on the shaft, bearing and the bearing coaxial connected load bearing hole. When being connected with assembly sleeve with a soft metal, such as copper or mild steel. The sleeve diameter slightly greater than the diameter of axle, outside diameter is slightly less than the bearing inner ring guard. Bearings shall be loaded at the same time when the shaft and hole, between the sleeve and bearing end face plus a clamp. Slightly smaller than the aperture is slightly greater than the diameter of axle, diameter of bearing outside diameter. Its role is to prevent the bearing outer ring hole deflection or stuck here. Pressure on the sleeve can be mechanical, but also the hydraulic. But absolutely not directly hammer ring width. Because the ring is a hardened thin wall parts, hammer easy to produce surface crack. 2. Heating installation install interference ring the force required to add the bearing size and cooperate with related to the size of the amount of interference. For larger amount of interference in medium and large bearing, often adopt the method of heating installation. Hot charging bearing in the front of the tank evenly heated to 80 ℃ ~ 100 ℃, and then from the oil on the shaft. Heating of the bearing should not be placed on the bottom to prevent precipitation impurities into the bearing. And should strictly control the oil temperature shall not exceed 100 ℃. According to the bearing batch size can also be other ways of electric heating, such as induction heater, electric heating plate and the electric furnace, etc. 3. Remove remove them ring and shaft is relatively tight fit, outer ring and a hole is loose fit inseparable bearing, shaft with bearings from the bearing hole first, then from the bearing on the shaft will be removed. Remove the inner and outer circle can be divided into bearing, axis, together with the inner ring will be removed first, and then from the inner ring on the shaft will be removed. Outer ring out of the bearing hole demolition. Detached or bearing from a shaft bearing inner ring by shaft removed available press. Screw mechanism is also available. When the outer ring here with a tight hole, the available pressure mechanism of outer pressure.
