Which environmental thrust cylindrical roller bearing vibration friction problem easily

Friction is mainly refers to the abnormal vibration of rolling bearing vibration, in general friction vibration likely to occur in large ball bearing, especially with grease lubrication grease lubrication performance not good when are more likely to happen. Derek bearing co. , LTD. Qingdao technicians according to the test and observation, the generation of thrust roller bearing friction vibration often have a direct bearing and lubricating oil properties. When the lubricant performance is bad or not clean, is prone to friction vibration, but also related to rolling bearing outer raceway machining quality, if the use of special precision machining method, can better control the friction vibration. Rolling bearing vibration is basically caused by the vibration of the bearing ring, and bearing structure, stiffness, manufacturing accuracy, installation and usage and other factors. If the roll bearing inner ring road have larger radial ripple, which ring rotates the bearing outer ring to produce radial vibration. Waves of bearing inner ring will not only cause the radial vibration of outer ring, but also will cause the axial vibration of outer ring, bearing when the axial load can make the bearing inner and outer ring of the axial relative position change, therefore, circle turns thrust cylindrical roller bearing outer ring mouth also produce axial vibration sieve at work, for high-speed rotating bearing, caused by the vibration frequency of corrugated, likely to equal the vibrator shaft rotational frequency, which produce resonance. A, keep the bearing and the surrounding environment clean even tiny dust into the bearing of invisible to the naked eye, also will increase the wear of the thrust cylindrical roller bearing, vibration and noise. Bearings and its surrounding accessories should be kept clean, especially the dust and dirt, tools and working environment must be clean. Second, use the installation should be careful when not allowed powerful punch, are not allowed to use hammer, direct tap on a cylindrical roller bearing, thrust is not allowed by transfer roller pressure. Three, using appropriate and accurate installation tools use a special tool, as far as possible to avoid use cloth class and short fiber, things like that. Four, to prevent rusting of the bearings directly with the hand take bearing, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. However, in some special operating conditions, bearing can get more than the life of the traditional computing, especially in the case of light load. These special operating conditions is, when the rolling surface ( Track and rolling piece) Can be separated by a lubricating oil film effectively and the surface of the limit of pollutants may cause damage. In fact, under ideal conditions, the so-called permanent bearing life is possible.
