How to judge the life of KOYO imported bearing running sound

Affecting the service life of KOYO bearings, there may be many factors that may be caused and the internal friction sounds have been further explained and used. The main factors used for adjustment are installation, use and maintenance, maintenance, etc. in line with technical requirements. According to the installation, use, maintenance, maintenance technical requirements of KOYO bearings, the bearing contact load, speed, lubrication status monitoring and inspection, found that the direct cause of the abnormality is adjusted back to normal.

Mounting conditions, one of the factors used for the bearing is the bearing force that often causes the state change between the parts of the incorrect installation package, the primary factor of the abnormal working temperature of the bearing, vibration, noise, gradual, the quality of the original material is improved. . The proportion of raw material quality factors in bearing failure analysis has dropped significantly, but it is still one of the main factors of bearing failure.

The choice of proper or not is still a bearing failure analysis that must be considered. Bearing manufacturing will pass the forging, heat treatment, turning, lubrication conditions to monitor and check the direct cause of the abnormality found, and the adjustment returns to normal. The installation condition is one of the factors that use the bearing is the primary factor that often causes the change of state between the various parts of the installation package, the main factor in the abnormal operating state, and the early termination of the inner life refers to the structure Design, quality manufacturing processes and materials, there are three factors that determine the quality of the bearing.

KOYO imported bearings are better than even if the shape will become a low hum, the impact will be knocking noise, this noise will collide and disagree according to KOYO imported bearing speed.

If intermittent noise is passed. If Sharp's buzz, creaking sounds and other sounds are not in accordance with the rules, often KOYO's imported bearings reveal poor performance and even reverse the situation.

Sharp's noise is not suitable because it is smooth and flat. Inappropriate KOYO imported bearing clearance will form a metallic sound. Will cause vibration KOYO imported bearings outer rail railway recessed indentation and form a smooth and loud sound. If the performance of the rolls is compromised, the components of the equipment are damaged. If any contaminants often cause buzzing, this sound is the date, KOYO imported bearings, and the appearance of the damage when it is damaged when rolling. Severe damage will occur in the order of the rules, but not very loud noise.

KOYO imports a major factor in the metallurgical quality of imported bearings that have a significant impact on the early failure of rolling. With metallurgical techniques (such as bearing steel, vacuum degassing, etc.) and other multi-channel processing assembly processes.

Introduction of methods and methods for regular lubrication and maintenance of SKF bearings

SKF bearing lubrication is best carried out during planned equipment downtime and is periodically replenished, while removing old grease or extruding old grease through the drain. Wipe the grease fittings clean before adding fresh grease. If the bearing housing of the SKF bearing does not have a grease fitting, the bearing housing cover or end cap should be opened to remove the old grease and, after cleaning, replenish the same type of fresh grease.

In order to ensure the normal operation of SKF bearings, we need to regularly check the oil level and oil quality of the lubricating oil. Under normal circumstances, the normal oil level should be within the range of 1/3-2/3 of the equipment oil level window or marking. The oil filling method is oil cup, the oil level shown only represents the oil replenishing capacity, and the bearing tank oil level is to meet the operation requirements. The oil level in the oil cup is less than 1/4 of its total volume.

The method of inspection and replenishment is to take a small amount of lubricating oil as a sample and compare it with fresh lubricating oil. The competent unit can consider the oil quality test to ensure the oil quality is qualified. If the sample looks cloudy, it may be the result of mixing with water, which is commonly referred to as oil emulsification. At this point, the lubricant should be replaced. If the sample is darkened or thickened, it may indicate that the lubricant has begun to carbonize and the old lubricant should be completely replaced. If possible, flush the oil line with fresh oil. When changing the lubricating oil, make sure that the new and old models of the replaced oil are the same and supplement the required oil level.

Use an oil bath type lubrication system. If the oil temperature is below 60 ° C (140 ° F) and the lubricant is not contaminated, replace the lubricant once a year. If the oil temperature is between 60-100 ° C (140-210 ° F), the lubricant needs to be replaced four times a year. If the oil temperature is between 100 and 120 ° C (210-250 ° F), the lubricant needs to be replaced once a month. If the oil temperature is above 120 ° C (250 ° F), the lubricant needs to be replaced once a week.

Proper installation and maintenance are important factors in the normal operation of the bearing. At the same time, care must be taken to maintain the cleanliness of the bearing. Bearings must be protected from contaminants and moisture and must be properly installed and lubricated. In addition, the design of the bearing arrangement, the condition of the oil seal, the form of the lubricant and the replacement cycle and the special maintenance also play an important role and must be paid attention to.
