Imported bearing installation and disassembly techniques

Manner using copper bar installed and manual 'this is a simple method of small and medium-sized import bearing. When the bearing inner ring is tight fit, a loose fit for outer ring, the copper rod bearing inner ring end face and directly with hammer percussion tongbang, through tongbang force, will slowly loaded on the shaft of the bearing. Bearing inner ring is larger, can use copper bar around the bearing inner ring end face even hitting, avoid by all means just knocking on one side, also can't overexert, symmetrical knock, knock on slowly, gently to avoid inclined crack bearing. 2. Using this method and use of copper rod sleeve installation imported bearing point is the same. It is a direct pressure on the bearing face the sleeve ( When the bearing is installed on the shaft pin inner ring end face; In a shell hole pressure within the outer end face) , hammer percussion force can be evenly distributed in the installation of the bearings on the ring width, and can be used together with the press, easy installation time and reliable in quality. Install the sleeve should be used in the soft metal manufacturing ( Copper or low carbon steel tube) 。 If the bearing installed on the shaft, sleeve inside diameter should be slightly bigger than the journal 1 - 4 mm, outside diameter is slightly less than the bearing inner ring rim diameter, or will be subject to the thickness of the sleeve, its thickness should be equal to the thickness of bearing inner ring made two-thirds - 4/5, and the sleeve ends should be flat and vertical tube body. When installing hole here if bearing, the sleeve diameter should be slightly smaller than bearing outside diameter. 3. There is a press into law: install pressure should be applied to directly import bearing ring width of interference fit, otherwise it can be crushed on bearing working surface, lead to bearing damage quickly. 4. The installed heating for interference quantity larger import bearings or large size bearings, to facilitate the installation, use principle of heat bilges cold shrink, heat the bearing in the tank with copper bar, the sleeve, and hammer after installation. General control heating temperature under 100 ℃, 80 - 90 ℃ is more appropriate. When the temperature is too high, easy to cause bearing ring raceway and rolling body annealing, hardness and wear resistance, decrease in bearing life and scrapped prematurely. When installation, can according to its type and size, select machinery, such as heating or hydraulic method. But in any case, all can't knock directly bearing ring, cage, rolling body or seals. When installed on the bearing force, never can be passed on from a roller bearing ring to another bearing ring, otherwise it may cause damage to the race. For clearance fit the bearing ring, it is recommended that the fitting surface with a thin layer of peristalsis etchant, in case of friction between mating surface corrosion. The correct installation, is very important for the use of imported bearings. I hope you can in the later use with correct installation method. Series 390000, outer spherical bearing is through the eccentric sleeve bearing inner ring with fixed axis, eccentric sleeve on the socket head cap screw fastening effect. With Allen wrench to loosen the lock screw on the eccentric bearing sets, and then with a small iron rod inserted into the roof sink hole on the eccentric sleeve, against the direction of the axis of rotation to play loose eccentric sleeve. Unscrew the fixed bolt of the bearing. From the bearing, together with the bearing on the shaft will be unloaded. Should be on the other end of the shaft bearing bolt loosening, lest bearings on both ends don't strength and damage to each other. Before installation imported bearings on the shaft, you must first remove the bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and shaft neck with anti-rust and lubrication oil ( Allows for a slightly bearings on the shaft rotation) 。 Coating on surface of the bearing and the bearing lubricating oil, put the bearing into the bearing seat. Pushed to the required location for installation. Fixed bearing bolts do not tighten, let bearing coat in bearing internal energy. Also installed on the same shaft, on the other side of the bearing and shaft turning laps, make automatic alignment position bearing itself. Then good bearing bolts. Eccentric sleeve. The eccentric sleeve installation is firm, finally lock eccentric sleeve on the socket head cap screw
