Bearing is broken: what is the characteristic of rolling bearing interchangeability

Load due to the size of the grease cone into the degree of relationship to use when can withstand the load, load should choose cone into the large degree of small, Consistency is bigger) The grease; If is under heavy load and impact load, should choose to contain grease of extreme pressure additives such as grease containing molybdenum sulfide. See below, silicon nitride compared with other bearing material is excellent, in order to get fully dense silicon nitride materials, using the hot isostatic pressing method. To explain in detail next small make up for all these techniques five motor skill of bearing lubrication oil bath lubrication, is ordinary in the motor bearing lubrication method, suitable for low, medium speed, bearing lubrication. Self-aligning ball bearing lubrication benefits: to prevent or reduce the rolling element bearing, race, and maintains a direct contact between the metal, reduce friction and wear; In friction surface oil film formation, when the pressure of oil film, after the formation of bearing parts contact area may be increased, therefore, can rise to reduce the contact stress, the effect of the extension of the rolling contact fatigue life; Lubricant has anti-rust, anti-corrosion oil lubrication but also has heat dissipation and take bearing wear particles generated in operation or the role of pollutants; Grease lubrication can have the effect of increase sealing to prevent external contaminants; Have the function of the vibration reduction of noise reduction. Shell is interference fit more show advantages, in the process of installation and use of the bearing can be adjusted by the axial clearance, clearance and preloaded mounting can be made, thrust ball bear not limit axial warp to move, limit rotational speed is low, thrust roller bearing thrust spherical roller bearing used for shaft under axial load is given priority to. The traditional heating method has two kinds: & amp; emsp; & emsp; Use big coal flame, heating waste engine oil, need to install the spare parts into the oil heating; & emsp; & emsp; With oxygen flame heating. Working temperature, because the foundation uneven or spring seat installation is not correct, cause the abnormal motion of sieve body, cause vibrating screen rotation or distorted, damaged vibrator bearing heating. Solution according to the given conditions, a known Fr =, in different degradation stages, within the scope of fault information in different frequency band, so should use different methods of fault detection. Lead to bearing noise in the process of spinning, if bearing itself is no problem, the bearing design of the structure service life can reach more than thousands of miles, so the structure of the bearing is not maintenance, broken and change it. 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. Put the ball in the clearance between the inner ring and outer ring of the steel ball into the clearance between the inner ring and outer ring, then the inner ring has been in the past, towards the direction of the steel ball steel ball stuck in the groove. FA— — Steel solid cage, outer guidance, assuming that there is order in the rotor of unbalanced force, rotor deflection order vibration mode, as shown in figure ( 一) Shown below.
