本空气静压轴承应用于游丝测试设备——游丝弹性后效仪。该仪器工作时转速很低(可看作零转速),支承系统的负荷小(负荷不到10克),但要求支承系统具有极低的摩擦力矩,特别是要求支承系统不能有明显的干扰力矩。本文着重分析了该轴承的结构选择,摩擦力矩的形成,承载能力及气膜刚度,并简要的介绍了该轴承材料的选择及气源的选择等有关制造中的注意事项。
The static pressure bearings used in the balance spring test equipment - balance spring After the instrument. The instrument operating speed is very low (can be seen as zero speed), the load on the support system is small (less than 10 grams load), but requires a very low friction torque bearing system, in particular, requires no significant interference with the bearing system torque . This article focuses on the structural choice of the bearing, the formation of friction torque, bearing capacity and film stiffness, and briefly introduces the bearing material selection and gas source selection and other manufacturing considerations.
