轴承的选型与计算 Bearing selection & Calculation

■ 轴承选型 Bearing selection

  峰成三复公司根据不同的工况条件设计了不同的轴承材料。用户在使用和设计时应当根据轴承的使用温度、轴承的承载面压、线速度、耐磨性能要求、运动类型、安装情况、轴承成本等方面因素综合考虑。
  SF BUSH have developed kinds of bearing material according to difference work condition, the user select the material base on bearing work environment , load, speed, wear, resistance request,moving method,installation,the cost of the material etc.

■ 面压计算 Bearing load
 
直套、翻边轴承 Cylidrncal bushes、flange bushes

  由于受配合间隙、材料强度、轴承倒角、内部油槽等原因的影响,轴承的真正承载面压(Pact)会大于理论计算值(Pmean)
  As the factor of clearance,bushes chemfer,oil groove etc.,the actually load(Pact)is higher than theory of calculation(Pmean).

线速度计算 Velocity

PV值计算 PV=PXV(N/mm2×m/s)

  PV是指轴承在一定的承载和线速度条件下的乘积之和。设备的PV与轴承的使用寿命成反比关系,因此建议设计时设备的PV取值尽量使用比较低的安全的PV值,以确保轴承会有更长的使用寿命。同时也要考虑设备上轴承实际的承载、线速度、使用温度等不能超过所选择材料的极限值,并尽可能地小。
  PV is the product of the specific bearing load P and the sliding speed V which is very important design data. We recommend design lower PV value will lead to longer service life.Also don't exceed the max.of material load,speed, temp.And lower if possible.
