Damage and Countermeasures of Partial Bearing Pedestal Made by Bearing Tight Sleeve Manufacturers

Damage to bearings: maintenance wounds and deformed or damaged cage frames, damage, these. Generally, bearings are lubricated with dilute vegetable oil and welding fume, which have different characteristics. However, considering the working standards of intelligent high speed and long time load working roller bearings, it may be considered that oil vapor lubrication is more suitable. Bearing agent Machine tool spindle bearings are a series of angular contact ball bearings composed of solid inner holes, outer sides, balls, and ball bearing components containing solid dialog box ball bearings. They cannot disassemble. This type of bearing can be opened and sealed. The dimensional tolerance of machine tool spindle bearings is relatively limited. They are very suitable for bearing layouts that require very high steering and speed operation capabilities. They are very suitable for the bearing layout of the rear axle of the equipment special tool. Asset impairment column. Inner hole deformation. Penetrate the surface of the dent. Through the guiding surface.

Cause: Poor installation (bearing discrete system). Incorrect operation. The torque load is very large. Shock, vibration. The speed is too fast, accelerating and decelerating quickly. Poor hydration. The temperature rises.

Manipulation: Inspection and installation methods of the manufacturer of the bearing adapter sleeve. Check load, rotation, and temperature standards. Reduce vibration. Adjust the selection of holders. Change the lubricating fluid and lubrication method.

Imprinting

Damage: Dents in the dovetail guide rail or rotating surface when biting metal powder, dirt, etc. Due to the hazards of installation and waiting time, spherical surfaces (tensile strength imprints) are created on the spacing of cold rolled bodies.

Reason: Ingestion of dirty things such as metal powder. 2. Impact when transporting or assembling under excessive load.

Countermeasures: 1. Impact coupling. 2. Improve sealing equipment. III. Filter grease. IV. Improve installation and operation methods.

Pyriform pitting

Damage: Pear shaped palm pattern with a dark brown gloss on the surface of the dovetail guide rail.

Reason: 1. During the whole process of moistening, there are dirty things and teeth occlusion. Poor hydration.

Countermeasures: 1. Improved sealing equipment. 2. Fully filter off the oil. 3. Moderate lubricating fluid.

damage

Damage: To be clear, the damage is caused by friction between the surface of the raceway or extrusion molding, the inner bore of the roller, the surface of the collar, and the spherical surface of the ball bearing.

Reasons: 1. The development trend caused by the invasion and rust of foreign characters. 2. The lubrication is not very good. 3. Falls due to irregular fitness exercises involving flipping objects

Countermeasures: 1. Improvement of sealing equipment. 2. Cleaning of bearing box. 3. Fully filtered lubricant. 4. Check the lubricating fluid and lubrication method. 5. Avoid discrete systems.

Microvibration damage

Damage condition: caused by the repeated contact between the surface relativity of the damaged dovetail guide rail and the flipping component, resulting in slight drag. Due to the formation of damaged grayish black and light brown powders, it is also known as abrasive etching.

Reason: 1. Poor hydration. 2. Some small amplitude shaking. III. Insufficient impact.

Countermeasures: 1. Apply appropriate lubricating grease. 2. Lift the prestressed tension. 3. Inspection is unnecessary. 4. Apply lubricant to the surface layer

peel

Damage: Slightly damaged black surface, several small cracks up to 5 meters deep from the surface to the black surface, and small scale drops (slight peeling).

Cause: The lubricating fluid is not good. Dirt enters the lubricating fluid. Poor roughness caused by lubricating fluid. The matching of the surface smoothness of the flipped part is not very good.

Countermeasures: Use lubricating fluid to improve the sealing performance of the equipment and improve the surface smoothness of the supporting facilities' flippers.

Card injury

Damage: To put it bluntly, a stuck injury refers to surface damage caused by accumulation of mild burns on a portion of the drag surface. A strip of wound in a circular orientation when dragging or flipping the surface layer. An iron clip wound on the wound of the roller thread at the end of the roller near the collar at the end of the roller.

Cause: The load is too large, and the prestress tension is too large, and the wetting is not good. Dirty things bite into the inner loop line, the second loop is skewed, and the axis is offset.
