1: How to improve the bearing accuracy:1, the precision spindle bearings and can not meet the requirements, after the bold and the fabrication journal roller to replace the inner ring and ball were measured waxy close to a size for every three groups ball close to 120 ° intervals to take separately, due to a decrease of the surface of a re-processing, but also reduces the surface with a weight, while improving the axial stiffness of a bearing system,
On the geometric accuracy, precision motion and positioning precision are high precision guide (such as CNC machine tools and measuring machines guide), the design should follow the following principles:Error compensation principle, meet the following three requirements in order to guide the system to achieve mutual error compensation:(1) rail link between the flexibility must be set to the middle,
1: bearing grease methods:Note fat content on the sealing performance of a large number of tests that, when the amount of grease within the bearing cavity volume is about 30% or less, due to the internal bearing no saturated fat, so very little grease leakage. Note more than 30% fat, bearing the internal local produce saturation, when the grease reaches 50%, the bearing grease to reach full saturation, excess fat is "squeezed" out. Special attention,
1, long life and resistance to wear - full ceramic bearing steel bearing fatigue life longer than expected 10-50 times, hybrid ceramic bearing, steel bearing life than the life span of 3-5 times higher;2, high speed and acceleration - can dn value of more than 3 million under the conditions of operation, and skidding, wear and heat can be reduced;3, corrosion-resistant - inert materials as ceramic materials, it is more corrosion and abrasion;
Data show that the wear and tear caused by mechanical failure or the main reason for the early, more than half of all management and lubrication technology. Improve lubrication management, and prevention of bearings, gears and other moving parts friction abrasions or sintering, to prevent and reduce wear, friction reduction, accident prevention equipment, improve equipment efficiency; saving energy, improving energy utilization efficiency,
1. Through the work to identify the temperatureThis method is more recognition method is limited to use in running condition is not change the situation. To this end, the temperature must be continuously recorded. Fails, not only temperature but also irregular changes.2. Through voice identificationTo identify needs through sound experience. Must be adequately trained to be able to identify the voice bearing and non bearing sound
INA Bearing Lubrication Methods Five1, manual lubricationINA Bearing lubricant is found insufficient, the timely use of fuel oil supply device, which is the most primitive methods. This approach is difficult to maintain a certain amount of oil due to the risk of neglect and forget big oil, usually used only for light load, low speed or intermittent movement of occasions. Best hole in the fuel set dust cover or valve, with blankets,
1, ntn Bearing Parts Material Imported bearing cage play an equal distance in the rolling bearing isolation to prevent the ball rolling and falling, to guide and promote the role of ball rotation. Can be divided into stamping rolling bearing cage and solid cage. Rolling at work, as a result of sliding friction and wear of bearings fever, especially in the high-speed operation conditions, due to the centrifugal force,
