SKF bearing storage, installation and test

A, SKF bearing storage: SKF bearing and seal storage conditions may have a negative impact on performance. Inventory control is also an important role on its performance, especially for the seals. Therefore, SKF bearing recommendation is to follow 'first-in, first-out' principles of inventory. Second, SKF bearing installation steps: 1, to ensure the work area clean. Check to ensure that the SKF bearing a precise size and shape. Should according to h9 / IT5 tolerance machining shaft, in order to install set of. 2, check to make sure that the bearing surface roughness for Ra 12 or less. 5 microns. Plane ( Flatness) Tolerances shall be IT7. To ensure the installation surface clean. If you use the gasket, the entire surface must cover gasket. The installation surface ( Structure) Design must be able to bear the actual load, vibration, and is suitable for assembly. 3, installed on the shaft between the two bearing seat of all parts. 4, if the SKF bearing is installed on the set set, to determine their relative to the position of the bearing. For outer ring with lubrication groove and three lubrication holes on spherical roller bearings, SKF recommended additional lubrication hole bearing center. Needs to add lubrication from SKF bearing side, for example, to the toroidal roller bearings or added since the self-aligning ball bearing lubrication, must pay attention to the position of the bearing, the grease nipple is located in the opposite side of the lock nut. When the bearing seat is located in the shaft end, grease should be at the side of the end cover to join. 5, place the SKF bearing in the bearing surface, mount connection bolt, but do not tighten. 6, in the shaft on the correct position of the first installation labyrinth seal. 7, SKF bearing installed on the shaft - — Directly on the ladder shaft or the use of set. Completely fill the bearing with grease. The rest of the grease is recommended should be put in on both sides of the bearing base. ( Table 1. ) 8, the correct position on the shaft is installed on the second circle of labyrinth. ( If you use the ladder shaft, first distance ring) 。 If the bearing is used in the shaft end, leave out the second seal, and insert an end cover on the bearing base. 9, according to the above four to eight steps to install the second SKF bearing and bearing seat. 10, will be equipped with two SKF bearing and labyrinth ring shaft in two and the base of the bearing. 11, for positioning end bearing configuration, and use the toroidal roller bearing configuration, on the each side of the bearing in a locating ring. 12, carefully on the bearing base. Both end and middle bearing base side vertical markers can be convenient to. Then, gently twist on two connecting bolts on the bearing seat. 13, put the two bearing seat cover in their base, and according to the ( Table 2. ) Specified torque tighten the cover bolts ( Connected to the top and bottom) 。 A bearing on the top and bottom not interchangeable with other on top and bottom of the bearing. Should check each bearing seat on the top and bottom and confirm them at the same serial number. 14, check the two in the case of the bearing, minimize is wrong, and fully tighten the two bearing seat at the base of the bolt connection. Recommended tightening torque (see Table 2. ) 。 15, finally synthesize hollow o-ring rubber belt embedded labyrinth ring groove. This step can use a screwdriver to complete while axis of rotation. Three, SKF bearing installation quality inspection methods, such as: 1, SKF bearing radial clearance reduction is upright; 2, measuring the initial radial clearance; 3, determine the clearance reduction is ( The initial clearance value - Clearance reduction is = final clearance value) ; 4, installation SKF bearing; 5, check in the process of SKF bearing drive radial clearance value finally. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
