Stable performance analysis IKO self-aligning roller bearing orbit operation notice some knowledge

When IKO bearing rotation, spherical roller bearing inner ring and outer ring raceway surface with rolling body is rolling contact, as the dark side, thus orbit trajectory are attached to the raceway surface does not belong to abnormal, the change can be learned that load conditions, so when remove the bearing, please keep close attention and observation on the surface of the raceway. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Accident can check whether the pair of roller bearing is added to the load and the installation error is large enough, etc. , shall be investigated and be bearing loss as a reason for clues. Contact seal is sealed parts with relative motion of parts no seal clearance. This seal due to seal direct contact with mating parts, therefore generally applies only to the medium and low speed working conditions. Friction at work is bigger, calorific value is big, make the contact friction losses, resulting in sealing effect and performance degradation. Contact sealed commonly used have felt seal, cup sealing structure, etc. According to the working conditions and working environment of IKO bearing the seal degree of requirements on the design of the spherical roller bearings are often integrated use of various seal form, in order to achieve better sealing effect. 1. Bearing assembly method because bearings are precision products, such as improper assembly channel, it is easy to damage the koyo bearings, bearing damage. In the bearing assembly should have a special mould, can't play when axial pressure force is only a small circle, circle, only according to the stress cycle. Pneumatic or hydraulic assembly requirements, the use of pressure to the mold under the outside installed in a horizontal state, if inclined to bearing channel will lead to the damage caused by the power, and make the bearing produces sound. 2. The removal of bearing and install also carefully. Note not koyo bearing and the damaged parts, especially interference fit the bearing down, and the operation is difficult. So, in the design stage to consider in advance to facilitate disassembly, designed and manufactured according to need remove the tools is also very important. When disassembling, according to the drawings the disassembly method, sequence, investigation of spherical roller bearing with conditions, to ensure foolproof disassembly operations. 3. IKO bearing material allows foreign hard particles in the lubricant pliers and prevent scratches or ( And) The ability of abrasive wear. For metallic materials with low hardness and elastic modulus, clamp in the sex is good, and the nonmetal material is not necessarily, carbon graphite, for example, low elastic modulus, but the clamp in the sex is bad. Self-aligning roller bearing usually use soft material and hard material forming friction, usually made from soft material bearing shell. 4. Check the bearing vibration in the working situation from peeling, indentation, rust, crack and wear will reflect in the IKO bearing vibration measurement, switch bearing vibration roller bearing damage is very sensitive, therefore, by adopting special bearing vibration measuring device ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation.
