Bearing width: how long will the sliding bearing lubricating oil change at a time

Such as turbine rotor assembly to the engine, in order to avoid rolling stick before turbine bearings roll bar block hoisting, commonly used vaseline coated between outer ring and the roll bar, to make the roll roll stick close to the outer ring road. The thread damage on the shaft, should undertake surfacing, threading, spline slotting fix high-speed bearings and plain bearing: the difference between high speed bearing is higher than the accuracy of the vulgar bearing, the surface roughness is smaller. Parts of the installation of static stress and residual stress loads caused by the stress interaction makes the stress state and direction perpendicular to the applied stress direction due to the propagation of the crack, therefore, due to the crack extension direction can get the information. & emsp; & emsp; SKF sealed spherical roller bearings, it is to pack sealing ring in the outer ring of the threaded, sealing ring of the sealing lip is contact with inner ring seal. Require the use of pneumatic or hydraulic assembly, lower die when being connected to outside the state level, such as with sloping NSK bearings can lead to channel due to mechanical damage, and make the NSK bearings produce guide ring. Figure bearing electric erosion trench under a microscope to see over-current damage of bearing structure only by scanning electron microscope ( SEM) , we can clearly see almost all damage to the surface with the potholes and mu m class welds ( As shown in figure which firm has a current through the bearing. Mm for increasing, through the analysis of the state of lubricant, and the identification of lubricant sampling, by its pollution degree is mixed with or metal powder and so on carries on the judgment, prevention measures: oil flow, timely supply the quantity of oil required for the bearing, sometimes bearing parts of the stress relaxation of the phenomena and the causes of size change. As the smoke of burning area will be more and more small, can use some tools, remove the point bearing grease, in light with fire, if drip drop point low grease, grease and high drop point. Check the materials compactness; I, install the assembly process of bearing assembly work, the installation process to ensure that the bearing clearance reaches normal operation of the technical requirements. Can be used in low temperature and wide temperature range, carry axial load and the power of the relevant contact Angle, the larger the contact Angle, can withstand the axial load. Insufficient lubrication ( The oil level is too low, save undeserved cause oil or grease seal leakage) ； , bearing in the mixed with sand or impurities such as carbon, abrasive effect; 。 Light weight, high strength: imported bearing shell has a variety of different types, from high overall quality of the cast iron casting, or high precision stamping steel manufacturing, at the same time of light weight with large intensity, the two different methods of stamping steel products has the characteristics of the lighter.
