Part shaft connection technology in the ultra-high speed motorized spindle, due to the increase of the speed, so on the shaft parts dynamic balance requirements are very high. Bearing positioning components and spindle is not suitable for thread connection, motor rotor and spindle is not suitable for key connection, and generally use detachable ladder interference connection. This kind of connection and thread connection has more obvious advantages than: (1) will not produce bending and torsional stress on the shaft, the shaft rotation precision has no impact; (2) easy to ensure that the parts positioning end and axis line of the vertical, the bearing preload will not make the bearing stress uneven and affect the life of the bearing; Interference sleeve quality is uniform, spindle dynamic balance is easy to ensure; (4) generally use the hot jacket method for installation, with the injection of pressure oil method for disassembly, no damage to the spindle; (5) reliable positioning, can improve the stiffness of the spindle.
