摘要： A pump insert (50) for supporting a rotor (14) of a pump comprises an annular resilient support (52) for engaging the body (26) of the pump, the support (52) extending about a rolling bearing (10) having an inner race (12) for engaging the rotor (14), an axially preloaded outer race (16) fixed to the support (52), and a plurality of rolling elements (18) located between the races. During assembly, the rolling bearing (10) can be accurately positioned within the support (52) so that there is a very low tolerance stack-up when the insert (50) is fitted to the rotor (14). Consequently, the position of the rotor (14) will hardly change, if at all, when the rolling bearing (10) is replaced during servicing of the pump.

摘要： Stray magnetic fields created by non-symmetrical magnetisation of the permanent magnets in a rotating magnet array of a magnetic bearing assembly, when used in turbo molecular pumps, can cause significant problems to devices such as scanning electron microscopes. In order to minimise the stray fields, at least the dipole and quadrupole moments of each magnet in the array is first measured. The magnets in the array are then arranged relative to one another such that both the dipole and quadrupole moments are minimised, thus minimising the stray magnetic field when the magnet array rotates in the turbomolecular pump.
摘要翻译：在涡轮分子泵中使用的磁轴承组件的旋转磁体阵列中的永磁体的非对称磁化产生的杂散磁场可能对诸如扫描电子显微镜的装置造成重大问题。为了最小化杂散场，首先测量阵列中每个磁体的至少偶极和四极矩。然后阵列中的磁体相对于彼此布置，使得偶极子和四极矩都被最小化，从而当磁体阵列在涡轮分子泵中旋转时最小化杂散磁场。
