Embodiment
The present invention relates to a kind of anti-vibration structure for motor, it is provided with the vibrationproof assembly with absorbing and buffering vibration between the central siphon internal diameter of motor and bearing outside diameter, its middle (center) bearing can be any pattern of oiliness bearing or ball bearing, the vibratory output that the vibratory output of motor rotor rotation and rotating shaft and bearing friction are produced can directly not be passed to the pedestal that central siphon is fixed, to intercept the influence of this vibratory output to electronic system.
Enumerating enforcement kenel and the conjunction with figs. that several the present invention apply to oiliness bearing motor and ball bearing motor respectively below describes.
As Fig. 2, shown in Figure 3, apply to the enforcement kenel of the radial windings motor of the axial coiling motor of oiliness bearing and oiliness bearing respectively for the present invention, both composition structures are roughly the same, and difference is the coiling kenel of stator pack 20,21 and the difference of central siphon 12,13;
Motor consists predominantly of pedestal 11, stator pack 20,21 and rotor 30.
Between central siphon 12,13 internal diameters and bearing 40 external diameters, be arranged with at least more than one vibrationproof assembly 41, vibrationproof assembly 41 must be by making with the elastomeric material of absorbing and buffering vibration, for example: rubber, excellent power glue ... the section configuration of the vibrationproof assembly 41 of present embodiment is two correspondences L font inwardly, and vibrationproof assembly 41 is coated on the outer peripheral face of bearing 40 and the bottom end surface that the bottom contacts with clasp, bearing 40 is not had with central siphon 12,13 directly contact.
