On the impact of external conditions for INA bearings

We therefore continuous monitoring INA bearing temperature is necessary, whether it is measuring the bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. Regular bearing temperature measurement by using a thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of INA bearings, means that when the damage cause of equipment downtime, so this type of INA bearings shall be mounted to the best temperature probe. Take a look at the influence of temperature on the bearing, using high temperature often said bearing is in abnormal situation. High temperature is harmful to the lubricant of INA bearings. Sometimes the INA bearing overheating can be classified to the INA bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, INA bearing ring, clearance, high friction and oil seal and so on. Vibration of the bearing damage is quite sensitive, peeling, indentation, rust, crack and wear will be reflected in the INA bearing vibration measuring. So, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. How to guarantee the INA bearing in the process of using normal, how to make the bearing no damage make bearing life longer. By me to explain for everybody below about considerations to ensure reliable work INA bearing, hope to help you. In general, ensure reliable work INA bearing note with the following requirements: first: the bearing clearance is proper, too big impact, poor lubrication is too small, may burn. Secondly, improve the quality of lubrication, control oil pressure, temperature and flow rate, strengthen the oil filtration. Third: INA bearings and shaft neck surface quality and geometry must be strictly guaranteed. Fourth: the conform to the provisions of the fuel and lubricating oil. Fifth: control the temperature of the diesel engine state, in the case of overheating too cold work will be unfavourable. Cold day, should be preheated before starting of diesel engine, with the hand cranking make the oil into the friction surface. According to the area of use and conditions of use and environmental conditions choose size, precision, with appropriate INA 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 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 INA bearings in - are allowed 30℃- Work under the temperature 150 ℃. Need to check on the machine running state, in the INA 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 bearing damage, to prevent unplanned maintenance equipment downtime INA bearing damage caused during the 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 engineer must adhere to the INA bearing fault signal alarm. Sound like the coo of a smooth career, high-pitched squeaky noise may be caused by a lack of bearing clearance caused by improper lubrication can cause metal sound. INA bearing outer ring grooves on the tracks will cause vibration. As if on scars caused by equipment can produce noise, the noise 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 INA bearing, and cause huge irregular noise. But at this time to replace a INA bearing is usually not necessary. So, of course, INA bearing damage, can also be perceived by listening. Such as using better methods, such as electronic health monitoring equipment, INA bearing eruption before operation.
