Motor bearing lock what reason be? How to solve?

Motor bearing lock key is refers to the motor bearings excessively high temperature can't again all the normal operation condition, usually appear this kind of condition can immediately will promote conversion motor bearing, basic can deal with the condition of motor bearing lock. The implications of motor bearing lock 1. To put it bluntly, bearing, holding in death of the bearing is in the whole operation process caused a lot of heat, heat can't dispersed in a short time. Cause bearing temperature rise sharply, bearing arms to death finally. 2. The status of the motor bearing lock in machinery and equipment repair, and manufacturing services is a wide range of on the spot. To check the motor bearing internal have grease is invalid, dry or bearing steel ball, the ball bearing, is subtle but won't harm bearing rotation, is due to the bearing after burning, bearings, bearing on inner and outer steel ball by linear expansion coefficient, lead to bearing the axial clearance narrowing, causing stuck; If any, and described the third condition and high speed for a long time, the lock is basically a must. 3. The sake of motor bearing lock ( 1) The poor quality of bearing; The braking system motor functions and principle of the braking system is what. ( 2) The poor quality of the bearing assembly; ( 3) Bearing the bearing chamber, inner and outer cover, oil slinger, curved parts such as vessel size tolerance deviation; ( 4) Bearing temperature alarm is ineffective; ( 5) Motor bearing installation, maintenance is not very good; ( 6) The bearing assembly is not good, 7) Assembly when bearing lateral and bearing holes or poor bearing inner hole and shaft to cooperate with each other. ( 8) Poor bearing assembly when bearing heating temperature control. ( 9) Poor bearing gap adjustment when bearing assembly. ( 10) Bearing skeleton seal not solved; ( 11) Not suitable for bearing gap; ( 12) Bearing RunHua not solve in time. How to deal with the motor bearing, holding in death of 1. For the lock of the bearing, the first in the installation, RunHua, cooling, heat removal, to ensure the appearance of the fasteners and size tolerance specifications, strict supervision on the bearing quality, strict in accordance with the instructions or repair plan, to prevent the bearing of the lock. 2. General bearing, holding in death of all bearing its own problems, such as roller bearings, destroyed, will cause the motor bearing lock, if the cylinder roller bearing damage is more serious, became a party that comes, motor bearing will lock, will lead to a motor or motor bearing, holding in death of the server, proposal immediately shut down, this kind of condition based can to solve the difficulties by means of changing the bearing. Motor bearing is the best around before and after the two into a swap. 3. If the motor bearings are often bad words, besides changing the motor bearing products quality problem, it is possible that the motor work when axial vibration, can adopt appropriate countermeasures both reduce the shock condition of motor bearing lock. 4. Motor bearing lock to the bearing inner hole and shaft tight mutual cooperation, the lateral and bearing hole is too loose when cooperate with each other, can press the bearing riveting first on the shaft, then connect the shaft bearings together into the bearing hole, riveting Kong Duan within the bearing surface, right pad the assembly waterproof casing made of a soft metal composite material ( Copper or mild steel) 。 Bearing outer close interaction with the bearing holes, inner hole and shaft for loose when cooperate with each other, bearing can be pressed into the bearing hole, first time assembly waterproof casing diameter should be slightly lower than the hole diameter. 5. Once appear, motor bearing lock safety accident, be sure to first cut off within the bearing pad, then drive shaft, and a cross the way or the other way. Repair specification and size tolerance of shaft, and then back to install according to the requirement, if the shaft is key, be sure to flaw detection to ensure the quality of the shaft. Be sure to do conversion solve when necessary. Motor is a kind of common motor bearing, holding in death of common failures, generally can be handled according to the changing bearing. Motor bearing is one of the more important position, in order to reduce the common fault of motor bearing to take effective countermeasures to motor bearing to carry out some maintenance. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website, updated daily different bearing little knowledge.
