INA bearings cylindrical hole installation method

INA bearing installation and removal methods, should according to INA bearing structure, size, and cooperate with INA bearing parts of nature. Installation, remove the pressure should be directly in the tight fit archives circle on the face, not through the transfer roller pressure, because it will cause indentation in the INA bearing working surface, affect normal work INA bearing, and even make the INA bearing damage. INA bearing cage, sealing ring, dust cover and so on parts is easy to deformation, install or remove the INA bearing pressure added on these parts. ( 1) INA bearing inner ring and the shaft is a tight fit, outer ring and shell as a loose fit, available press will first pressed on INA bearings, INA bearing and axle load along with INA bearing shell, when pressed on the INA bearing face a soft pad metal materials assembling casing ( Copper or soft steel tube) 。 Assembling casing inside diameter should be slightly larger than the diameter of a journal, outside diameter should be less than the rim diameter of INA bearing inside diameter, to avoid pressure in keeping the frame. When installing the INA bearing large can add a handle on the casing. INA bearing installation to make the INA bearing hole and the shaft centerline. INA bearings relative axial skewed installation difficulties not only, and will cause the indentation, shaft bending, and even can make the INA bearing inner ring fracture. Where the missing or cannot use press, assembling casing and small hammer can install INA bearings. Hammer force should be evenly spread to INA bearing ring end face of the whole on the circumference of a circle, therefore assembling casing under the hammer face should be made into spherical. ( 2) INA bearing outer ring and shell holes for tight fit, inner ring and the shaft for a loose fit, INA bearings can be pressed into the housing first, then assembling casing diameter should be slightly less than the diameter of the shell hole. ( 3) INA bearing inner ring and the shaft, the outer ring and shell holes are tight fit, assembling casing can end should be made at the same time pressure INA bearing inner and outer ring width of the circle, or use the disc and assembling casing, make the pressure at the same time to the inside and outside the circle, the INA bearing pressure into the shaft and housing. This installation method is particularly suited to automatically adjust heart to the heart of the spherical bearing installation. ( 4) Installed heating, INA bearing the force required to INA bearing size and cooperate with related to the size of the amount of interference, the interference to the large amount of medium and large INA bearings commonly used the method of hot charging. The INA bearing before hot charging or separable INA bearing ring into the fuel tank or dedicated heater evenly heating to 80 ~ 100 ℃ ( Should not exceed 100 ℃) 。 The skilled operation skills are needed for hot charging INA bearings. When INA bearings after removed from the heating in the fuel tank or heater, should immediately with a clean cloth ( Can't use cotton yarn) Wipe grease stain on the surface of the INA bearing and attachments, and then put forward, on the surface of the INA bearing in an operation to resist the position of the shoulder. ( 5) Should always push tight in the cooling process, or with a small hammer by assembling casing tap INA bearings make it tight. When installation should be slightly twisted INA bearings, in case the installation tilt or jammed. INA bearing outer ring and shell holes for tight fit when also can put the shell after heating into INA bearings. Especially in light metal manufacturing INA bearing under the condition of the tight fit, may damage due to press the INA bearing outer ring into the blend surface, at this time should be INA bearing heating.
