HRB bearing or the preparation before installation and the correct method for bearing sales center in jiaxing

There is rotational, have HRB bearing ( ) HRB bearing or the preparation before installation and the correct method for bearing sales center in jiaxing. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. 1. Before the installation of cleaning: bearing into bearing, bearing and the bearing running between space must be kept clean, or bearing rolling surface easy to scratch and pitting corrosion; Bearing seat before installation, must to clean inside the bearing seat. 2. Bearing the seal of detection: more for double seal bearing seat, bearing sealing performance is critical, so the seal must be installed is compact, not a seal gap, otherwise easy to early damage of bearing. Insert half split lips sealed bearing sealing groove on either side of the base. The seal the space between the two lips fill grease. And if the bearing is used for shaft end inserted in the side cover to replace the seals. 3. Mounting holes and with fixed detection: bearing before installation, the installation hole whether standard, whether mounting holes with fixed hole corresponding, after installation and the fixed degree is the standard of the bearing, the above data to check before installation. 4. Check the supporting surface roughness detection. If the bearing installed on the set set, determine the direction of bearing seat. The nozzle position of bearing seat lid should always on the other side of the tight sleeve nut. Must pay attention to the direction of the bearing, because the direction of the lid and the base is to be prepared in accordance with the original installation. To determine the bearing direction on the surface of the support. Fitted with anchor bolt but do not tighten. Bearing should be installed according to the bearing structure, size and cooperate with properties of bearing parts, pressure should be directly in the tight fit on the ring width, shall not be passed on roller pressure, bearing installation commonly adopt the following methods: a. Force fit tight fit bearing inner ring and the shaft, the outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal materials ( Copper or mild steel) 。 Bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, the bearing can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the bearing ring and shaft and hole is a tight fit, install indoor ring and outer ring to pressure into the shaft and hole, at the same time assembling casing structure should be able to at the same time, so the bearing inner ring and outer ring end face. b。 Heated by heating the bearing or bearing seat, the use of thermal expansion will fit into a loose fit installation method. Installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearing, the bearing before hot charging type or separable bearing ring into the fuel tank 80 - uniform heat 100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and shoulder joint is not tight, bearing axial fastening again after cooling. Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch. Tank heating bearing, from a distance place is due at the bottom of a mesh, as shown in figure 2 7, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring. c。 The installation of the thrust bearing thrust bearing of the matching of the thorough and axis is commonly transition fit, seat and the bearing holes with the general for the clearance fit, so this kind of bearing is easy to install, two-way thrust bearing axial spring should be fixed on the shaft, in order to prevent the relative to the axis of rotation. Bearing installation method, usually is the situation of the axis of rotation, so the inner ring cooperate for win cooperate with shaft, with the bearing outer ring and bearing chamber for clearance fit. Low, bearing inspection bearings after installation, operation should be performed immediately check, has determined whether normal installation.
