选择和使用SKF轴承的预防措施betway电子竞技俱乐部

来源:skf轴承 时间:2021-05-21

  Checking the condition of the machines in operation and preparing a thorough inspection plan has become more and more serious. Among them, the bearing is the focus of attention, because it is the most important rotating part in all machines. Condition monitoring is an important part of preventive maintenance. Early detection of bearing damage to avoid equipment downtime during unplanned maintenance due to bearing damage. However, not all of them are equipped with this advanced instrument. In this case, the operator or maintenance engineer of the machine must be highly alert to the "fault signals" of the bearing, such as noise, temperature and vibration. "Listening", "touching" and "observing" are three important factors. The views provided below can be used as your reference.

  High temperature often indicates that the bearing is in abnormal condition. High temperatures are also harmful to the lubricants in SKF bearings. Sometimes bearing overheating can be attributed to the lubricant of the bearing. Long-term operation of the bearing at a temperature exceeding 125 degrees Celsius will reduce the life of the bearing. The reasons for the high temperature of the bearing include: insufficient or excessive lubrication, impurities in the lubricant, and excessive load , Bearing damage, insufficient clearance, and high temperature friction caused by oil seals, etc. Therefore, continuous monitoring of bearing temperature is necessary, whether it is measuring the bearing itself or other important parts. If the operating conditions do not change, any temperature change may indicate that a malfunction has occurred.

   The bearing temperature can be measured regularly with the help of a thermometer, which can accurately measure the bearing temperature and display it in degrees Celsius. The important bearing means that when it is damaged, it will cause the shutdown of the equipment, so it is best to install a temperature detector for this type of bearing. Under normal circumstances, the bearing will have a natural temperature rise just after lubrication or relubrication and it will last for one or two days.

1.轴承型号的选择:轴承模型通常由用户的技术人员根据配套产品的使用条件和负载轴承选择。业务人员主要知道用户的实际负载是否与所选轴承一致。如果轴承不符合使用要求,应建议客户尽快改变模型,但除非在选择模型中有特殊产品,否则通常会有任何问题。

2.轴承间隙的选择:用户在购买轴承时,一般只告知型号和等级,很少询问轴承的间隙。业务人员必须询问轴承的操作条件,轴承的速度和温度。配合公差直接关系到轴承间隙的选择。一般情况下,转速低于3500 rpm的电机大多采用CM间隙,如高温和高速电机,要求间隙比较大。装配后,轴承间隙会由于内孔的膨胀和外圆的收缩而减小。间隙的减少=干涉量× 60%(轴承室为铝除外)。例如,轴承装配前的间隙为0.01mm,装配期间的过盈量为0.01mm,则轴承装配后的间隙为0.004mm。理论上,有零间隙时轴承的噪声和寿命达到最佳状态,但在实际运行中,考虑到温升等问题,装配后轴承的间隙最好为0.002mm-0.004mm。

3.润滑脂的选择:润滑脂的选择通常是基于SKF轴承的速度,耐温性,噪音要求和启动扭矩。betway电子竞技俱乐部企业人员必须熟悉各种润滑脂的表现。

4.轴承密封类型的选择:轴承润滑可分为油润滑和润滑脂润滑。油润滑轴承一般选用轴承形式,油润滑轴承一般用防尘帽或橡胶密封件密封。防尘罩适用于高温或良好的使用环境。密封分为接触式密封和非接触式密封。接触式密封具有良好的抗尘性,但启动力矩大;非连接式密封具有较小的启动力矩,但密封性能好。没有接触是好的。

betway电子竞技俱乐部SKF轴承目前在汽车电机轴承,家电电机轴承,摩托车轴承和保健电机轴承等行业中专业生产,因此轴承的噪音和寿命最佳。
