Abstract
The utility model relates to a shock absorption device for a permanent magnetic wind power generator. The shock absorption device for the permanent magnetic wind power generator comprises a disk which is arranged in a motor stator shell and is used for limiting the longitudinal movement of a rotor; and a shock absorption structure capable of absorbing shock and protecting parts of the permanent magnetic wind power generator is arranged between an end cover of the shell and the disk. The utility model aims to overcome the defects in the prior art and provide a shock absorption device for a permanent magnetic wind power generator, which is simple in structure and remarkable in damping effect.
Description
[technical field]
The utility model relates to a kind of vibration absorber that is used for permanent-magnetic wind driven generator.
[background technology]
Existing permanent-magnetic wind driven generator is installed on fan blade on the cantilevered axle that the motor front end stretches out, because the fan blade diameter of wind-driven generator is big, and discontinuity, it is frequent to quicken, slow down, thereby the wind-driven generator of this structure very easily causes the motor body vibration.In order to reduce the body vibration of wind-driven generator, just require motor overall structure rigidity big, therefore, the technical scheme that prior art is taked is the weight and volume that further increases motor, makes originally more to show heavy with regard to heavy, volume with regard to big wind-force electrical machinery.
The utility model is based on that this situation makes.
[utility model content]
The utility model has overcome the deficiency of prior art, and a kind of simple in structure, vibration absorber that damping effect significantly is used for permanent-magnetic wind driven generator is provided.
The utility model adopts following technical scheme for solving the problems of the technologies described above:
A kind of vibration absorber that is used for permanent-magnetic wind driven generator; It is characterized in that including the disk that spacing rotor vertically moves that rises that is arranged on the motor stator enclosure, between shell end cap and disk, be provided with the vibration-proof structure of damping and protection permanent-magnetic wind driven generator parts.
Aforesaid a kind of vibration absorber that is used for permanent-magnetic wind driven generator; It is characterized in that described vibration-proof structure includes flexible member that is arranged on the disk inwall and the elastic component that is arranged on shell end cap inwall, is provided with steel ball between described flexible member and elastic component.
Aforesaid a kind of vibration absorber that is used for permanent-magnetic wind driven generator is characterized in that described flexible member is provided with semi-circular recesses, and described steel ball places in the semi-circular recesses, between described flexible member and steel ball, leaves the buffering spacing.
The utility model compared with prior art has following advantage:
The utility model is employed in the vibration-proof structure that is provided with damping and protection permanent-magnetic wind driven generator parts between motor housing end cap and the disk; This vibration-proof structure is employed in the disk inwall and is provided with flexible member and is provided with elastic component at motor housing end cap inwall; The structure of steel ball is set between flexible member and elastic component; This vibration-proof structure can play vibration damping and protection permanent-magnetic wind driven generator parts at the permanent-magnetic wind driven generator run duration; Avoid parts to be impacted, simple in structure, be easy to install and damping effect obvious.
[description of drawings]
Fig. 1 is the utility model sketch map.
Fig. 2 is an A place enlarged drawing among Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of vibration absorber that is used for permanent-magnetic wind driven generator; Include and be arranged on the disk 2 that motor stator shell 1 an inner spacing rotor vertically moves, between shell end cap 3 and disk 2, be provided with the vibration-proof structure 4 of damping and protection permanent-magnetic wind driven generator parts.
Described vibration-proof structure 4 includes flexible member 41 that is arranged on disk 2 inwalls and the elastic component 42 that is arranged on shell end cap 3 inwalls; Between described super-elasticity element 41 and elastic component 42, be provided with steel ball 43; Described flexible member 41 can be isolated steel ball 43 and the effect of playing buffering; Described elastic component 42 has pastes performance preferably, can stick on the stator casing inwall.
Described flexible member 41 is provided with semi-circular recesses 411, and described steel ball 43 places in the semi-circular recesses 411, between described flexible member 41 and steel ball 43, leaves the buffering space D, and this buffering space D can guarantee the cushion space of steel ball 43 when motion.
