IKO bearing CAM troubleshooting method analysis

IKO bearings revealed in the process of operation failure is often the case, so there's no need to its. Revealed the fault, judgment and disposal is the key. 1. Bearing temperature is too high, when the agency is running the installation of bearing parts to allow a certain temperature, when the hand touch body shell, should not feel hot as normal, by contrast, suggests that CAM bearing temperature is too high. Bearing temperature comprised: lubricating oil quality unsatisfactory or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Space is not enough) ; IKO bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; CAM bearing maintain or bone fracture, etc. 2. Bearing noise bone bearing allowed in the office have tiny interview, if the interview is too large or there are abnormal noise or sound, suggests that the bearing failure. Bone bearing comprised of noise is more complex, one is the bearing inner and outer ring wear appropriate appearance. Because this kind of wear and tear, damage the IKO bearing the right relationship, and shell, bearing and shaft axis caused by stray accurate position, grew louder when shaft in high-speed motion. Metal flake when bearing fatigue, its appearance, also can make bearing radial clearance increases grew louder. This besides, inadequate bearing grease, dry friction, as well as bearing broken initiation abnormal sound. CAM bearing wear loose after kuang, maintain relaxation are destroyed, will also initiation sound bearing is damaged. Bone bearing removing a sense, can be on the basis of the bearing was damaged bearing faults and destroy things condition judgment comprised. 1. Metal flake bearing raceway appearance bone body and inner and outer ring raceway surface all bear the periodic fluctuating load utility, thus initiation period changes of contact stress. When the stress cycle number back after reaching a certain number, bearings, their office within bone body or on the initiation of fatigue spalling. If the bearing load is too big, can make this kind of tired. Additional, IKO bearing installation is not straight, axial buckling, initiation of raceway flaking off. CAM bearing raceway fatigue spalling can reduce the working precision of shaft, result in vibration and noise of institutions. 2. Bearing burning burning IKO bearing raceway, bone have heat tint on the body. Burning is comprised of ordinary lubricating oil is not sufficient, the lubricating oil quality undesirable or deterioration, and bearing assembly too tight. 3. Plastic deformation of bearing raceway and roller contact surface revealed warp all potholes, explained the bearing initiation plastic variant. Port is IKO bearing in very large under static load or shock load utility, office appearance of part stress exceed the material yield limit, this kind of thing common happened in the low-speed rotation of the bearing condition. 4. Bearing race of the bearing race of crack initiation crack comprised may be bearing appropriate tight, IKO bearing abnormal or relaxation of inner ring, including a variant of CAM bearing, bearing installation looks bad processing, etc. 5. To maintain its plane rupture by the lubricating oil is not enough, bone broken body, seat skew, etc. 6. Maintain the metal frame paste on the bone body may be card is comprised of bone body in maintaining aircraft or lubricating oil is not sufficient. 7. Seat ring raceway serious abrasion likely is a circle into foreign body, lubricating oil is not sufficient or lubricating oil brand is not appropriate.
