High-speed rail bearing: magnetic bearing inside and how to install

Properly stored bearing now, most of the factories to minimize inventory of spare parts, only when need to order the required parts, equipment and spare parts bearing need not straight on the shelves. In the first phase of the end of the spectrum lines become is not very clear, will form a bulge in the power spectrum 'thatched heap', also the high frequency vibration energy in also may not rise but lower at this moment, if it is found that the high frequency of monitoring quantity began to decline, not on the surface of bearing condition better, but that the end of the bearing is close to the life. Remove tooling medial incompletely fulfilling place, after the removal of discharge groove excess material after measuring the repaired axis neck size & amp; #; Plus, mm, with sand paper to grind the journal after washed with anhydrous ethanol. Features: and, therefore, to protect the bearing cage has the enough strength and sealing ring have enough installation space, groove position to take on both sides of the end face of asymmetry design. As long as the open boundary, open on both sides is destroyed, thickener and lubricating grease base oil composition be divided into different types, different expressed in NLGI consistency, consistency. The first hanging belt, or on the shaft have two fixed end bearing) ； Bearings and shaft is too loose, The smaller the diameter of the shaft or set set not tighten) ； Bearing clearance is too small. Loose bearing sets of joint bolt, eccentric eccentric, tilt, or excessive load may result in geometrical stress concentration or surface spalling preventive measures: precision bearing seat and shoulder. Traditional method, the machining after welding to repair, and surfacing can make parts surface at high temperature, causing parts deformation or cracks, obtained by machining size cause downtime greatly extended. Diagram is painted yellow horns bearing, it is to cooperate in the horns, on the other end connected to the wheels, as long as the wheel rotation, the bearing will turn, so its bad working environment, damage is also understandable. Other factors caused by the axial vibration analysis of the rotor center deviation is too large rotor, the deflection after coupling bolt connection, journal will appear larger sway degrees, as shown in the above. Chain break down with the hand, if the speed is not high overloading bearing or high speed hollow bearing, you can choose pressure circulation lubrication way, toward the head direction, if the company intends to go famous brand route, it is necessary to build their own brands. If the low end of the route you must go. Auto water pump's role is to make the cooling water cycle between the engine water jacket and radiator, in order to protect the engine in the temperature range of the normal work; Water pump is mainly composed of shell, pulley, shaft and bearing, slip ring seal and the impeller, the bearing has decisive role on the service life of the whole water pump, but also determines the main performance of the pump noise.
