Bearing installation method

Should be taken before the installation of the bearings with petrol or kerosene wash clean, dry after use, and to ensure good lubrication, grease lubrication bearing general use, also can use oil lubrication. Using grease lubrication, should choose without impurities, antioxidant, antirust, superior performance, such as extreme pressure grease. Grease filling quantity for bearings and bearing box - 30% of the volume 60%, unfavorable and overmuch. With sealing structure of double row circular cone roller bearings had been filling grease, users can directly use, not for cleaning. Bearing installation, it must be in the ring width on the circumference of a circle of equal pressure, to press the ring into, can not use ð ¨ +  top tools directly on bearing face, in order to avoid damage In the case of a small amount of interference, but at room temperature with the sleeve pin on the ring width, with a ð ¨ +  head banging on sleeve, through the sleeve ring and balanced If large quantities of installation, can use hydraulic press. Fashionable, should guarantee the outer end face and the shell shoulder end face, inner ring end face and the shaft shoulder end face pressure, there is no gap. When large amounts of interference, can use oil bath heating or sensor heating method to install the bearing, the heating temperature range of 80 ℃ - More than 129 ℃, 100 ℃, the highest can't. At the same time, nut or other appropriate method is applied to tighten the bearing, in order to prevent the bearing width after cooling contraction and make the clearance between the ring and the shaft shoulder. Choosing cooperation should focus on the following four: ( 1) Freedom end bearing must be able to adapt to changing with the length of the shaft and bearing seat holes, which must have to adapt to the axial location within a certain range of swimming ability. ( 2) Must pay attention to the bearing installation and easy disassembly, saving time and expenses for the province. ( 3) Bearing ring circumferential surface should have good bearing and force uniform, in order to reduce the deformation, and can give full play to the bearing capacity of the bearing. ( 4) Ring in its surface can't slide along the tangent direction, otherwise it will damage the mating surface.
