The impact of NSK bearing manipulator time on life

In the design process of NSK bearing manipulator, when determining the maximum stroke of each action, the time of each action can be allocated according to the work rhythm required by the production, thereby determining the moving speed of each action.


When designing the manipulator action, it should be completed within the time specified by the working rhythm. The distribution of time depends on many factors. According to various factors, it can be determined by comparing power distribution plans. The total action time of the manipulator should be less than or equal to the working rhythm. If two actions are performed at the same time, the following requirements should be considered when calculating and allocating the time for each action based on the length of time.


NSK bearing vibration is very sensitive to damage such as peeling, indentation, corrosion, cracking and wear of the bearing, which can be reflected in the vibration measurement of deep groove ball bearings. Therefore, a dedicated bearing vibration measuring device (frequency analyzer, etc.) can be used to measure vibration, and abnormal conditions cannot be inferred from the frequency. The measured value of the bearing changes with the working state of the bearing or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measured value of each machine before determining the judgment standard.


The bearing temperature is generally inferred from the outdoor temperature of the bearing. It is more suitable if the oil hole can be used to directly measure the temperature of the bearing outer ring.


Under normal circumstances, the temperature of deep groove ball NSK bearings slowly rises with the beginning of bearing operation, and reaches a stable state after 1-2 hours. The heat capacity, heat dissipation, speed and load of the bearing chamber temperature randomizer are different. If the lubrication and installation of parts are appropriate, the bearing temperature will rise sharply and the bearing will experience abnormally high temperatures. At this time, we must stop working and take necessary precautions.


The thermal sensor is used to monitor the working temperature of the bearing at any time. When the temperature exceeds the specified value, it will automatically report to the well or shut down to prevent shaft burnout accidents.


High wen is usually used to indicate that the bearing is in an abnormal state. High temperature is also harmful to the lubricant of the bearing. Sometimes the overheating of deep groove ball NSK bearings can be attributed to the lubricant of the bearing. If the bearing temperature exceeds 125 degrees Celsius for a long time, the service life of the bearing will be reduced. Causes of high bearing temperature include insufficient or excessive lubrication and excessive lubrication. Containing impurities, excessive load, damage to the bearing ring, insufficient clearance, oil seal friction, etc.


Therefore, whether it is measuring the bearing itself or other important parts, it is necessary to continuously monitor the temperature of the deep groove ball bearing. If working conditions remain the same, any temperature change may indicate a malfunction.


Periodic measurement of NSK bearing temperature can be done with a thermometer, such as a digital thermometer, which can precisely measure the bearing temperature and display the bearing temperature in units of temperature or Fahrenheit.


Important bearings refer to equipment downtime caused by bearing damage. Therefore, for this deep groove ball bearing, it is best to install a temperature detector.


Generally, the bearing will naturally heat up after lubrication or relubrication, and it will last for one to two days.
