For as long as possible to maintain in good condition bearing the original performance, required maintenance, repair order to prevent accidents in the first place, to ensure the reliability of operation, improve productivity, economy. Operating standards, maintenance of the best corresponding mechanical operation conditions on a regular basis. The content includes monitoring the operation state, to supplement or replace the lubricant periodic disassembly inspection. Considerations overhaul operation, with rotation of the bearing sound, vibration, temperature, lubricant status, etc..
: Removing the lower bearing maintenance for cleaning of the bearing, the first record of the appearance of the bearing, to confirm the residual amount of the lubricant, to sampling inspection lubricant after cleaning the bearing. As a cleaning agent, ordinary gasoline, kerosene. The removed bearing cleaning, cleaning and fine cleaning sub-coarse, were placed in the container, first put the metal bottom of the network, bearing no direct contact with the container dirt. The rough cleaning the bearing with dirt rotation, will damage the bearing rolling surface, it should be noted. Rough cleaning oil, use a brush to remove to grease, adhesive material, generally clean, transferred to sperm washing. Sperm washing, cleaning oil bearing while rotating, while carefully cleaning. In addition, cleaning the oil should be kept clean.
Bearing overhaul and judgment: In order to determine whether the removed bearing can be used to check bearing wash. Check raceway, rolling surface, with the surface state, cage wear, increased bearing clearance and damage decreased unrelated dimensional accuracy exception. Non-separable type of small ball bearings, the inner ring with one hand and the level of support the rotating outer ring to confirm whether smooth. Tapered roller bearings and other separation-shaped bearing, rolling element, the outer ring raceway were examined. Rotating the large bearing failure hand, pay attention to check the rolling body raceway to maintain the appearance of the rack, wall surface, the importance of bearing the higher the greater the need for careful checking.
Use of rolling bearings of various mechanical devices, instruments, and other market increasingly stringent performance requirements, bearing the required conditions, the performance is also becoming more diverse. In order from the large number of structures, sizes, select the most suitable bearing, and need to be studied from various angles. In the choice of bearings, generally, considering as shafting bearing arrangement, the difficulty of installation, removal, substantially determined by the bearing structure, bearing permit the space, the size and the bearing market. Secondly, while Comparative Study bearing a variety of mechanical design life and bearing a variety of endurance limit, while deciding the bearing size. Select bearings, often biased only consider the fatigue life of the bearing, about life grease grease aging, wear, noise, etc. also need to be adequately studied. Furthermore, according to different uses, it is necessary to select the accuracy, clearance, and to maintain the requirements of the frame structure, grease, etc., as the special design of the bearing. However, the choice of bearings and in no particular order, the rules, the priority should be considered the conditions required on the bearing performance, most related matters, particularly practical.
