Bearing in English: 3 what support shaft bearing

Inventory over years of bearings have to clean oil, in addition heat induction heating device can be used to heat the bearing installation so that it has expanded again after installed on the shaft, bearing inventory every year should be to clean the oil in the oil seal packing good, the bearing is separation model, when users to install, can according to need to adjust the clearance. Select the type of bearing and the way of combination, the spindle assembly be taken into account in all aspects of requirements, as well as the supply of the bearing, cost, it is the ease of installation and debugging and other factors. 'N' outer rim, this kind of bearing installation, remove the more convenient, especially when the inner and outer ring and the shaft, when the shell is interference fit showed more advantages. Number of drying cylinder shaft to repair this cooperation is, mm in diameter, uneven wear quantity for mm, bearing and the bearing with the method of withdrawal fit, between a drying cylinder bearing wear repair operation steps. Some motor factory in recent years on the adoption of two ball bearing pole motor using large clearance ball bearing, bearing heat makes it is ease for runtime clearance measures of reducing incur bearing damage. Back pressure and back pressure, is must exist, in theory, the greater the back pressure of automobile exhaust system, the stronger the exhaust noise control capability, at the same time, exhaust resistance. / electric car dozen feet overhead clearly hear the sound of the motor in a box, this kind of question is bearing rock lead to more, need to replace new bearing. Principle: try to open in the bearing section, try not to reduce or less bearing area of the oil film bearing capacity; Axial groove can't open end to bearing, appropriate oil cover shall be maintained. Thermoplastic deformation ( Or high temperature deformation) Grinding heat in the work surface layer of the instantaneous temperature, make the depth of the workpiece surface layer elastic limit fell sharply, even to the point of elastic disappear. So, under heavy load situations and demands radial size, structure compact occasions (such as internal combustion engine crankshaft bearing) , use sliding bearing more; Particularly sensitive to metal scraps, rolling bearings bearings into, can produce bigger vibration and noise in an intermittent, also can cause early damage. Repair welding machining process itself is easy to make shaft surface local produce thermal stress, cause the hidden trouble of the broken shaft, repair welding and machining process need to spend a lot of manpower and time to disassembly, transport and installation of equipment, the repair time is longer, synthesis of the high cost of repair, long-term stop production will also be a lot of economic loss caused to the enterprise. First, we can see the defects on bearing ring fracture reasons are: raw materials mixing, osteoporosis, brittle element segregation or carbide liquid chromatography, mesh, ribbon, not survived well and other defects in processing work together not to be, or improve, can cause stress concentration and weaken the ferrule basic strength, become the source of crack.
