Influenced the stability of the one-way bearing vibration check method of operation

The key factors affecting the service life of TIMKEN bearings for rotating machinery products many key parts in their service life depends on the product more bearing parts of life. Bearing 'free maintenance' is not a one-way bearing will never damage or failure but not damage within a certain amount of time. Here the designers to calculate the bearing service life of the bearing life is greater than or equal to the overhaul period of such bearing mechanical products can 'maintenance' in the overhaul of mechanical products and replace new bearing can don't need to use a bearing maintenance. Grease lubrication of filling grease in the seal type bearing in advance sealing way, and in the shell internal filling amount of grease, every once in a while to supplement or replace the packing way for fat. In addition, there are more than one-way bearing need lubrication of mechanical, also USES the pipe connection to the lubrication for lipid concentrate way. Grease lubrication can do a grease filling after long time don't need to be added, and the structure of the sealing device is also relatively simple, so widely used. Oil lubrication is relatively simple. Often can improve the service life of TIMKEN bearing lubrication. Imported bearing in the work to allow running noise slightly, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. Due to the wear and tear, damage to the bearings and shell, bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the TIMKEN bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Bearing wear loose after kuang, maintains a looseness damage, also can produce sound. Installed in institutions, there is the part of the one-way bearing a certain temperature, when the hand touch body shell, should not feel hot as normal, conversely indicates that bearing temperature is too high. The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ; TIMKEN bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. Determined by one-way bearing structure design parameters of stiffness, flexibility, quality, such as damping of vibration system under the condition of operation will produce that can meet the needs of its mechanical vibration. Manufacturing process of the deviation caused by vibration, the smaller the deviation, the less vibration. Roundness, waviness and surface roughness on the surface of the steel ball is the most profound effect on the vibration in the bearing parts, followed by the shape of the inner ring and outer ring channel error and surface roughness, again is a one-way bearing cleanliness and quality of lubricant, etc. Operation conditions such as the installation conditions, speed, direction of axial load, quantity, etc.
