The effect of oscillation of imported bearings on bearing failure

The effect of oscillation of imported bearings on bearing failure

Oscillation of imported bearings has an obvious effect on the failure of bearings. For example: spalling, indentation, corrosion, cracks, wear, etc. will be reflected in the imported bearing oscillation detection, so through the use of special imported bearing oscillation measurement equipment (frequency analyser and oscillator, etc.) can be measured by the size of the oscillation, through the frequency distribution can be deduced from the specific circumstances of the abnormal oscillation, the measured value due to the use of imported bearings, or the sensor device orientation and so on, and thus the need for prior The measured value of each machine is analysed and compared to determine the standard imported bearings. Usually the temperature of imported bearings with the beginning of the work slowly rise, 1 to 2 small

Imported bearings and shaft fit tolerance standard rules

Imported bearings and shaft fit tolerance standard rules

I. Rolling bearings ① when the bearing inner diameter tolerance zone and shaft tolerance zone constitute a fit, in the general base hole system originally belongs to the transition with the tolerance code will become over win with, such as k5, k6, m5, m6, n6, etc., but the amount of over win is not big; When the bearing inner diameter tolerance generation and h5, h6, g5, g6, etc. constitute a fit, not in the gap and become over win with. ② bearing outer diameter tolerance zone due to the tolerance value is different from the general reference shaft, is also a special tolerance zone, in most cases, the outer ring is installed in the shell hole is fixed, some bearing parts structural requirements and need to be adjusted, its fit should not be too tight, often with H6, H7,

How to judge the degree of damage of imported bearings

How to judge the degree of damage of imported bearings

Through the failure and deterioration of imported bearings, performance state parameters to judge and predict the reliability and performance of bearings, the part of the abnormal situation, the cause and the degree of danger to identify and judge, decide to repair and improve the method of comprehensive technology. Therefore, bearing fault diagnosis technology is not pure fault detection (or monitoring) technology, also is not pure point inspection instrumentation. Correct, rapid and effective signal acquisition, data processing, manual or automatic identification and judgement. In order to determine the scientific repair cycle, should also be based on the mechanism of various types of failure, fatigue, wear life of the necessary tests and estimates. Judgement of bearings in use

What effect does the limiting speed of the bearing have on causing noise?

What effect does the limiting speed of the bearing have on causing noise?

Bearing raceway sound and its control method Raceway sound is when the imported bearings running, its rolling body rolling on the raceway surface and issued a kind of slippery continuous sound, is all rolling bearings will happen the unique basic sound. General bearing sound is the raceway sound plus other sound. Ball bearing raceway sound is irregular, frequency in 1000Hz above, its main frequency does not change with the speed, but its total sound pressure level with the speed of speed and increase. Raceway sound big bearing, its raceway sound sound pressure level with the viscosity of the increase and reduce; And raceway sound small bearing, its sound pressure level in the viscosity increased to about 20mm

JOJI gives you the answer: Can domestic precision bearings surpass imported bearings

When China's high-speed rail leads the world with a total mileage of 45,000 kilometers, it still needs to spend billions of dollars annually on importing bearings; when the annual domestic production of bearings exceeds 30 billion sets, the high-end market is monopolized by the eight international giants with a 75% share. The question of "whether domestic precision bearings can surpass imports" has always lingered in the journey of manufacturing industry upgrading. In Wuxi, a hotspot for manufacturing, Zhongfu Power (Wuxi) Co., Ltd. has given a clear response after ten years of deep cultivation: domestic bearings are breaking the monopoly with technological breakthroughs, achieving a leap from following to running alongside in the precision manufacturing race.

JOJI Bearings: Teaching you how to better distinguish between roller bearings and ball bearings when purchasing

In the core transmission parts of mechanical equipment, the selection of bearings directly affects the equipment's lifespan and operational efficiency. Roller bearings and ball bearings, as the two most commonly used types of rolling bearings, may seem similar, but they have vastly different application scenarios. Wuxi JOJI, with years of deep experience in the bearing field and a wealth of application cases, will break down the core differences and procurement logic between the two for you.

JOJI Bearings: Macroscopic world, microscopic precision, floating power, following the Tao to perfection

When we gaze upon the magnificent vista of the macro industrial world—high-speed trains speeding across mountains and rivers, intelligent machine tools precisely cutting and sculpting precision components, wind turbine blades rotating in the wind to capture clean energy, and heavy machinery roaring in operation to support infrastructure construction—few people would notice that behind these grand operations lies a microscopic yet crucial core role: bearings. As the "joints" of mechanical systems, bearings, with their millimeter-level delicate structures, carry the crucial mission of power transmission and friction reduction. Their precision, lifespan, and stability directly determine the efficiency and safety of macro equipment.
