IKO bearing overheating caused failure of solutions

( 1) Rolling bearings with low noise requirements in the production of standard IKO bearings, some short single centripetal ball bearings and cylindrical roller bearings are for the use of motor bearing varieties of low noise. The ball bearing from inner diameter phi 2. 5 mm to phi 60 mm have several varieties with Zl, Z2 and Z3 three suffixes, corresponding to three different types of low noise, and roller bearing from N309 type to type N322 eight models have made according to standard low noise. These IKO bearings can apply to other machines with low noise requirements, and the price is cheap, as on the type and size can be request, try to use the two types of low-noise bearings. ( 2) Using relatively small bearing noise when not using the above two types of low noise bearings, IKO bearing noise is relatively small can be used. Specific comparison basis is as follows: 1) The noise of the ball bearing is lower than that of the roller bearing, relatively less sliding bearing ( Friction) More noise than the relative sliding bearing is low; 2) Using entities cage IKO bearing noise is relatively lower than using punching cage bearing; Using the plastic cage bearing noise than using the above two cage bearing are low; Count more, outer ring thickness, noise is small; 3) High precision bearings, especially the higher precision of the rolling element bearing, its noise than low precision bearing noise is relatively small; 4) Small bearing noise than the big bearing noise is relatively small. IKO bearing failure of the main reason is that defects and overload two factors. When the loads more than material strength limit fracture caused by parts called overload fracture. Overload reason mainly is the main engine failure or improper installation. Bearing parts of micro crack, shrinkage cavity, bubbles and large foreign impurities, overheating organizations and local burns and other defects during the impact overload or violent vibration will cause fracture in defect, known as defect fracture. It should be pointed out that the bearing in the process of manufacturing, for raw materials into the factory reinspection, forging and heat treatment quality control, process control through instrument analysis of the existence of the above defects and correct still must strengthen control in the future. But in general, usually bearing fracture failure of most for overload failure.
