Koyo bearing correct device:
1. View the dimensions and finishing conditions of the dry components
2. Clear bearing and bearing components
3. Device
4. View after installing the bearing
5. Supply smoothing agent is expected to be in front of the device; just open the bearing packaging. Generally smooth grease smooth; do not remove; directly filled with smooth grease. Smooth oil smooth; generally do not need to remove; but; instrument or high-speed bearings, etc.; Wash the oil; remove the anti-rust agent coated on the bearing. Remove the bearing of the anti-rust agent; easy to rust; so can not be placed regardless. Further; the bearing has been sealed with smooth grease;
Bearing device method; due to bearing layout, cooperation, conditions; general; because most of the shaft rotation; so the inner ring demand interference cooperation. Cylindrical hole bearings; multi-use presses; or more hot-packing method. Cone hole Occasionally; directly on the taper shaft; or with a sleeve device.
When the device is to the outer casing; generally the clearance cooperation is more; the outer ring has the interference; the press is generally pressed; or there is also the cold shrinking cooperation method of the cooling device. The dry ice is used as the coolant; the cold shrinking cooperation device; the air The moisture in the water will condense on the outer surface of the bearing. Therefore, the appropriate anti-rust method is required.
Faulty check in the homework:
1, the oscillation of the bearing
The koyo bearing oscillation is very sensitive to the damage of the bearing; for example, shedding, indentation, rust, crack, wear, etc. will be reflected in the bearing oscillation measurement; therefore; after selecting a special bearing oscillation measuring device (frequency analyzer, etc.) can be measured The large oscillating ü 德 豢 豢 豢 豢 豢 豢 5 5 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭After the comparison, the discriminant specification is determined.
2, the temperature of the bearing
The temperature of the koyo bearing; generally the temperature outside the bearing can be estimated; if the oil hole can directly measure the bearing outer ring temperature; it is more suitable. Generally; the temperature of the bearing gradually rises with the beginning of the operation; 1-2 hours After reaching the steady state. The normal temperature of the bearing is due to the heat capacity of the machine; the heat dissipation; the speed and load are different. If it is smooth and the device is suitable, the bearing temperature will rise sharply; abnormal temperature will occur; it is necessary to stop the operation; Adopt the necessary precautions. Based on many test data; Table 4-1 lists the average value of the outer ring temperature during bearing operation in various machines; for reference. Because the temperature is affected by smoothness, speed, load, and environment; The median value only indicates the approximate temperature scale. The thermal temperature sensor can be used to monitor the operating temperature of the bearing at any time; and when the temperature exceeds the specified value, the alarm is activated or the ignition is avoided.
3. The rolling sound of the bearing is selected by the sounder to check the size and sound quality of the rolling sound of the bearing in the operation; even if the bearing has slight peeling damage, etc.; abnormal sounds and irregular sounds will be announced; the sounder can be used to distinguish .
