Precautions for wear of IKO linear bearing during operation

  • The size of the working clearance will directly affect its working performance and service life. The working clearance is subject to centrifugal force. Manufacturers and users mostly manufacture and select bearings according to the radial clearance.
  • As a clearance, it refers to the clearance when the linear bearing is in a stable working state. Proper working clearance will help to improve the research of the closing system, and the correlation of various factors is not considered.
  • The calculated results have a large deviation from the actual situation. In fact, the temperature field of the bearing is non-uniform, and the three are interrelated.Precautions for wear of IKO linear cuscinetto during operation

  • In genere, if the bearing is used correctly, può essere utilizzato fino al raggiungimento della vita a fatica. Tuttavia, ci saranno danni accidentali e prematuri, which is not resistant to use. Questo danno iniziale, al contrario della vita a fatica, is the quality service limit known as failure or accident.
  • La maggior parte di essi sono causati da un'installazione incauta, uso e lubrificazione, materia straniera invadente dall'esterno, and insufficient research on the thermal effects of shafts and shells.
  • In the operation of IKO bearing, there are many factors affecting its clearance, mainly including temperature change, centrifugal force and fit of linear bearing. In the working process, the working clearance changes due to the influence of centrifugal force, fit and temperature. Qualche volta, the influence of the same three factors is not isolated from each other, but interrelated.
  •  Perciò, only in this way can we correctly reflect the influence of the three on the working clearance of the bearing in actual work, so as to reasonably determine the bearing clearance and improve the working efficiency and operation accuracy of the bearing
  • As for the damage state of IKO bearing, such as the clamping damage of the ring and retaining edge of roller bearing, these reasons can be considered as insufficient lubricant, unsuitable, defects of oil supply and drainage structure, invasione di materie estere, installation error of linear bearing and excessive deflection of shaft.Precautions for wear of IKO linear bearing during operation

  • The selection of specifications, dimensions and accuracy according to the service parts, service conditions and environmental conditions, and the matching of appropriate bearings are the premise to ensure the service life and feasibility of bearings.Precautions for wear of IKO linear bearing during operation
  • Posizione dell'applicazione: tapered roller bearing is suitable for bearing the combined radial and axial load dominated by radial load. It is usually used in pairs with two sets of bearings. It is mainly used in the transmission parts of automobile, such as front and rear hubs, driving bevel gears, differential, reducer and so on.Precautions for wear of IKO linear bearing during operation
  • Allowable speed: under the condition of correct installation and good lubrication, the allowable speed is 0.3-0.5 times of the limit speed of linear bearing. Under normal conditions, it is appropriate to use 0.2 times of the limit speed.Precautions for wear of IKO linear bearing during operation
  • .Allowable tilt angle: IKO bearings generally do not allow the shaft to tilt relative to the shell hole. If there is any tilt, the greater is no more than 2 ‘.Precautions for wear of IKO linear bearing during operation
  • Allowable temperature: under the condition of bearing normal load, high temperature resistance of lubricant and sufficient lubrication, the general bearing is allowed to work at the ambient temperature of – 30 ℃ – 150 ℃.
  • The running state of the machine that needs to be checked is the focus of attention in the bearing, and it is becoming more and more important to prepare a thorough inspection scheme.
  • Because it is an important condition monitoring of all rotating machinery components to prevent bearing damage and to prevent early detection of IKO bearing damage during unplanned maintenance equipment shutdown, it is an important part at home.
  • But not all machines are equipped with this advanced equipment. In questo caso, the machine operator or maintenance engineer must insist on the bearing fault signal alarm.Precautions for wear of IKO linear bearing during operation
  • Perciò, solo indagando sul danno al cuscinetto, è difficile conoscere la vera causa del danno. Tuttavia, if we know the use machinery and conditions of the bearing, the structure around the linear bearing, the situation before and after the accident, and combined with the damage state of IKO bearing and several causes, we can prevent the recurrence of similar accidents.
