If the linear motion bearing is well lubricated and correctly blocks sundries and moisture, it means that the oil seal should not be worn However, when opening the bearing housing, check the bearing and regularly check the oil seal Check the condition of oil seals near the bearing to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from penetrating into the bearing along the axis. If the oil seal is worn, replace it as soon as possible.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
High temperature often indicates that the bearing is in abnormal condition High temperature lubricants are also harmful in bearings Sometimes bearing overheating can be attributed to the lubricant of the bearing If the linear motion bearing operates for a long time at a temperature of more than 125 ℃, the service life of the bearing will be reduced.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
The causes of high-temperature bearing include insufficient or excessive lubrication, magazine contained in lubricant, excessive load, bearing damage, insufficient clearance, high-temperature friction caused by oil seal, etc
Check the condition of the running machine and monitor it to avoid equipment shutdown
The synthetic radial load on the fixed load is exposed from the local ring raceway fixed ring and transmitted to the corresponding shaft or bearing. The characteristic of this load is that the radial load vector is a relatively static synthesis and ring. The load bearing ring can be used relatively loose.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
The rotating load is the full loaded cylindrical roller bearing ring acting on the synthetic radial load on the drum rotating along the circumferential direction. The rotating parts, such as the rotating burden, are borne by the synthetic vector phase ring radial load rotation.
The rotating load ring fits closely. In special cases, the load, if selected, is a light or heavy load at low speed. Only occasionally, the ring, bearing adopts hard material and high surface roughness. The rotating load bearing ring can also be used to be relatively loose.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
Third, the load of load swing or non directional load, and the synthetic direction of radial load of load ring is uncertain. It is characterized by the action of radial load vector ring raceway of synthetic ring, impact load, vibration and load in a certain area. Its direction is swing.
The roller has to bear a certain area or the load acting on the bearing, and the load value often changes. To bear the load swing, the outer ring and circumference, bearing and hole should be used closely.
The common methods to adjust the radial clearance of fully loaded cylindrical roller bearings are as follows:
Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
1. The side clearance of cylindrical and oval bearing shells can be adjusted by manual grinding and scraping or by adding pad on the bearing split and scraping after turning.
2. The top clearance of cylindrical and oval bearing shells can be adjusted by manual grinding and scraping or adding pad to the bearing split when circumstances permit.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
3. In principle, it is not allowed to scrape and adjust the clearance of multi oil wedge fixed bearing bush. If the clearance is inappropriate, replace it with a new one.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
4. For multi oil wedge tilting bearing bush, it is not allowed to scrape the pad. If the clearance is not appropriate, replace the pad. For tile with adjustable thickness, the amount of tile can be adjusted by adjusting the stainless steel pad on the back of the tile or reducing the thickness of the adjustment block.
Note that for the multi oil wedge tilting bearing bush, the thickness error between the same group of pads shall be less than 0.01mm.Influence of Radial Clearance Adjustment of Fully loaded Cylindrical Roller Bearing on load
