INA thrust angular contact ball bearing with lubrication maintenance skills - bearing knowledge

Role is to make the bearing fits of stationary ring and rotating ring, respectively, and installation of bearing parts of the stationary part ( Usually bearing) And rotating parts ( Usually the shaft, Consolidation in together, so as to realize in the condition of rotating relative to the static load and limited movement system the basic task of the system location. In the shaft and bearing, thrust angular contact ball bearings in the radial, axial and tangential direction to three directions such as fixed position. Through the positioning of the radial and tangential INA bearing ring tight fit the mining of implementation, the axial positioning only in a few cases with tight fit; Generally USES the axial spacing parts, such as end cover and retainer could happen on the axial location clearance range. Choosing cooperation should focus on the following four: ( 1) Bearing ring circumferential surface should have good bearing and force uniform, in order to reduce the deformation, and can give full play to the bearing capacity of the INA bearings. ( 2) Ring in its surface can't slide along the tangent direction, otherwise it will damage the mating surface. ( 3) Freedom end bearing must be able to adapt to changing with the length of the shaft and bearing seat holes, which must have to adapt to the axial location within a certain range of swimming ability. ( 4) Must pay attention to make the thrust angular contact ball bearing installation and easy disassembly, saving time and costs for the province. Oil bath lubrication is the most common lubrication method, suitable for low, medium speed, lubrication bearing, INA bearing part of immersion in the slot, the bearing parts of lubricating oil by rotating, and then flow back to the oil level of oil tank should be slightly lower than the lowest at the center of the roller. Oil drip lubrication is suitable for need to ration oil bearing parts, drip oil every 3 - general A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. Filter in the oil pump oil to the bearing parts, through the thrust angular contact ball bearing lubricating oil filter cooling after use. Due to the circulating oil can take a certain quantity of heat, cooling the bearing, therefore method is suitable for high speed bearing parts. Mixed with dry compressed air after the sprayer and oil formation oil mist, spray INA bearings, can effectively make the bearing cooling airflow and can prevent the intrusion. This method is suitable for high speed, high temperature lubrication bearing parts. With oil pump to pass through the nozzle shot into the bearing, high pressure oil into the bearing of the bearing at the other end into the oil in the tank. When thrust angular contact ball bearing at high speed, rolling element and cage with high rotate speed makes the surrounding air, the air with general lubrication methods are difficult to be sent to INA bearings, lubricating oil and lubricating oil spray must use the method of high-pressure jet to bearing, the position of the nozzle should be placed between inner ring and retainer center.
