INA plane bearing considering use and installation process

You'd better not use in their own vehicles worn or damaged INA bearings, because it may will bring you in the process of driving unsafe factors, serious word will cause harm to the life safety. So in the use of the use of plain bearing and the installation process must pay attention to matters: 1. How to limit axial position, including the radial and axial location is the first issue to consider. General shaft adopts double supporting structure, more limited jointly by two supporting shaft radial position, each bearing radial position should have the function of plane bearing. Axial position can be made up of two supporting various restrictions in one direction axial displacement can also be used by a bearing limit the axial displacement of two directions, in general, different axial positioning way running accuracy can be different. Therefore, supporting structure should be designed according to INA shaft working accuracy and working conditions, choose the concrete scheme of the axial positioning. 2. At the same time bear radial load and axial load, bearing often adopt bearing installed in pairs. There are three kinds of arrangement plane bearing installed in pairs. Two bearing outer ring width end installed relatively say back to back. Two point falls outside of the bearing span of supporting force. This arrangement for supporting large span, shaft bracket with good rigidity, axial thermal elongation when the inner and outer ring off, so shaft not stuck, it is widely used. Installation, but if the preload in the shaft when heated preloaded quantity will be reduced. Two narrow bearing outer ring end face relative installation according to installation way face to face. Both the force bearing point falls within the bearing span. This arrangement has simple structure, convenient installation and debugging are also so it is widely used, mainly used in the occasion of short axis and temperature is not high, but should pay attention to must have spare clearance. Axial clearance also shoulds not be too large, will reduce the shaft running accuracy. When the axial load is bigger, need to multiple INA bearings under at the same time, often by relative bearing outer ring width and narrow surface installation mode of series. All the force bearing point fall within the same side of the bearing arrangement is also called tandem therefore calls. Using this kind of arrangement must pay attention to the structure and manufacturing to ensure every imported bearing with uniform load as far as possible. 3. Machines in operation, the general main shaft or the shaft temperature higher than the temperature of the adjacent parts, thus axis will heat to elongation. In order to maintain flexible rotation axis, in supporting structure design, satisfy the requirement of axial positioning accuracy in at the same time, consider the requirements of shaft heat free expansion. The axial positioning and is corresponding to the axial expansion. 4. Adjust bearing clearance is running accuracy to control shaft. Axial position adjustment is in order to meet the special requirements of some meshing transmission. For example: in the worm drive, must fall in the middle of the worm gear and worm axis plane in order to assure the correct mesh, and thus require worm shaft can be adjusted in the axial position. In the bevel gear transmission, two section of bevel gear cone cone vertex must overlap, and therefore require two bevel gear shaft axial adjustment.
