About KOYO bearing vibration when dealing with problems

In the general case, as the world's top bearing KOYO bearing vibration will not occur, but if there is a vibration, then you must to check the situation well, here we give you describe vibration occurred in the truth. 1. When we are wuxi bearing damage local vibration may occur. Due to the operation or installation errors, a small number of bearing raceway and rolling element may be damaged. In the running, rolled the damaged bearing parts will produce a particular vibration frequency. Vibration frequency analysis can identify the damaged bearing parts. When KOYO bearing not waviness appear deformation vibration may occur. Close cooperation between bearing ring with the bearing or the shaft, bearing ring with adjacent components are likely to match the shape and deformation. If there is a deformation, can produce vibration in the operation. Therefore, the bearing and the shaft are machined to the required tolerance is very important. In applications where also produces vibration behavior, in many applications, the bearing stiffness with the surrounding the stiffness of the same structure. Due to this feature, as long as the correct choice bearing ( Including the preload and clearance) And its application in the configuration, it is possible to reduce the application of vibration. And while the number of rolling load change and the vibration. When a load on a bearing radial load, the number of rolling element bearing load will be a slight change in the operation, i. e. , this caused the load in the direction of migration. The resulting vibration is inevitable, but can be by axial preload to ease, loading in all rolling body ( Do not apply to the cylindrical roller bearing) 。 To introduce the three small method can reduce the KOYO bearing vibration. 1. Change the stiffness of structure, so as to change the critical frequency. 2. Get rid of critical excitation vibration from the application. 3. Antimicrobial resistance stimulate critical excitation vibration between components and the resonance components. According to the area of use and conditions of use and environmental conditions choose size, precision, with appropriate KOYO bearings is the prerequisite of bearing life and feasibility. 1, use parts: tapered roller bearing is suitable for predominantly radial load under the combination of radial and axial load, usually used in two sets of bearing pairs, mainly should be in the car before and after the wheel hub, active transmission parts, such as bevel gear, differential, reducer. 2, allows speed: under the correct installation, lubrication good environment, allowing for KOYO bearing limit speed of 0. 3 - 0. 5 times. Generally under normal circumstances, with 0. 2 times the limit speed for the most appropriate. 3, allows tilt Angle: taper roller bearings are generally not allowed to have tilted axis relative to the shell hole, if there are any tilt, no more than 2 '. 4, allow temperature: under normal load, and lubricant has a high temperature resistant performance, and abundant lubrication conditions, general KOYO bearing in - are allowed 30℃- Work under the temperature 150 ℃. Need to check on the machine running state, in the bearing is the focus of attention, and prepare to thoroughly check scheme has become more and more important. Because it is the most important of all components of the rotating machinery condition monitoring, in order to prevent damage of KOYO bearing, to prevent unplanned maintenance equipment downtime bearing damage caused during the period of early detection of an important component part of the home. But not all the machines are equipped with the advanced equipment. In this case, the machine operators or maintenance engineers must adhere to KOYO bearing fault signal alarm. Sound like the coo of a smooth career, high-pitched squeaky noise may be caused by a lack of KOYO bearing gap caused by improper lubrication can cause metal sound. Bearing outer ring grooves on the tracks will cause vibration. As if on scars caused by equipment can produce noise, the noise KOYO bearing level at different speeds. If there are intermittent noise, and then rolling part, may be damaged, the sound, when the damage the surface of the launch date, if bearing hiss 'sound pollution often cause serious damage to the bearing, and cause huge irregular noise. But usually at this time to replace a KOYO bearing is unnecessary. So, of course, bearing damage, can also be perceived by listening. Such as using better methods, such as electronic health monitoring equipment, bearing eruption before operation.
