Prevent premature failure of INA high speed turbine dental drill mobile phone bearings
Regarding the damage state of the high-speed turbine dental drill mobile phone bearing, such as the ferrule of the roller bearing and the framing of the rib, as a cause, the lubricant is insufficient, unsuitable, the defect of the oil supply structure, the intrusion of foreign matter, the bearing installation The error and the deflection of the shaft are too large, and these reasons will coincide.
There are many factors that may affect the service life of INA bearings. The main factors for adjustment are installation, use and maintenance, maintenance, etc., which must meet the technical requirements. According to the technical requirements of the installation, use, maintenance and maintenance of the bearing, the high-speed turbine dental drill mobile phone bearing contact load, speed, lubrication state monitoring and inspection, found that the direct cause of the abnormality is adjusted back to normal.
Mounting conditions, one of the factors used for the bearing is the bearing force that often causes the state change between the parts of the incorrect installation package, the primary factor of the abnormal working temperature of the bearing, vibration, noise, gradual, the quality of the original material is improved. . The proportion of raw material quality factors in INA bearing failure analysis has dropped significantly, but it is still one of the main factors in the failure of high-speed turbine dental drill mobile phone bearings.
The choice of proper or not is still a bearing failure analysis that must be considered. INA bearing manufacturing will pass the forging, heat treatment, turning, lubrication conditions to monitor and check the direct cause of the abnormality found, and the adjustment returns to normal. The installation condition is one of the factors that use the bearing is the primary factor that often causes the change of state between the various parts of the installation package, the main factor in the abnormal operating state, and the early termination of the inner life refers to the structure Design, quality manufacturing processes and materials, three factors determine the quality of high-speed turbine dental drill mobile phone bearings.
Bearings are better than even if the shape becomes a low hum, and knocking noise will occur, which will collide and distract depending on the bearing speed. If intermittent noise is passed. If Sharp's buzz, creaking sounds and other sounds are not in accordance with the rules, often poorly performing bearings reveal and even reverse the situation.
In general, if the INA bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and cannot be used. This early damage, as opposed to fatigue life, is a quality use limit called a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing.
Therefore, it is difficult to know the true cause of the damage by only investigating the bearing damage. However, if you know the mechanical use of the bearing, the conditions of use, the structure around the high-speed turbine drill mobile phone bearing, and understand the situation before and after the accident, combined with the damage state of the INA bearing and several reasons, it can prevent similar accidents from happening again.
