Bearing high speed rotation precautions

Core Tip: When the bearing rotates at high speed, especially when the speed is close to or exceeds the limit speed recorded in the dimension table, the following should be noted: (1) using precision bearings; (2) analyzing the inside of the bearing
When the bearing rotates at high speed, especially when the speed is close to or exceeds the limit speed stated in the dimension table, the following should be noted:

     (1) use precision bearings;

     (2) Analyze the internal clearance of the bearing (considering the reduction of the internal clearance of the bearing caused by the temperature rise);

     (3) Analyze the type of material of the cage (for high-speed rotation, it is suitable to use a copper alloy or phenolic resin cutting cage. There is also a synthetic resin molding cage suitable for high-speed rotation);

     (4) Analyze the lubrication method (using lubrication methods such as circulating lubrication, jet lubrication, oil mist lubrication and oil and gas lubrication for high-speed rotation)

Causes and treatment of motor bearing overheating

Core Tip: Causes and treatment of motor bearing overheating (1) Bearing damage should be replaced. (2) The rolling bearing grease is too small, too much or has iron scraps and other impurities. The capacity of the bearing grease should not exceed
Causes and treatment of motor bearing overheating

    (1) The bearing is damaged and should be replaced.
    (2) The rolling bearing grease is too small, too much or has iron scraps and other impurities. The capacity of the bearing grease should not exceed 70% of the total volume. Those with impurities should be replaced.
    (3) The shaft and the bearing are too tight or too loose. When it is too tight, it should be reground. If it is too loose, it should be set to the shaft.
    (4) The bearing and the end cap are too tight or too loose. The bearing housing is machined when it is too tight, and the steel sleeve is placed inside the end cover when it is too loose.
    (5) Poor assembly of the motor end caps or bearing caps. Install or flatten the end cap or bearing cap stop and tighten the screws.
    (6) The belt is too tight or the coupling is poorly assembled. Adjust the belt tension and correct the coupling.
    (7) The sliding bearing lubricant is too little, there is impurity or the oil ring is stuck. Repair or replace the oil ring, such as refueling, replacing oil.
