Description
Technical field
This utility model relates to motor accessory technical field, especially relates to a kind of permanent-magnetic synchronous motor rotor.
Background technology
At present, permagnetic synchronous motor obtains and is widely popularized, and it utilizes permanent magnet to set up magnetic field, have easy to use, the advantage such as be active in one's movements. But, people always expect the preparation cost that can as much as possible reduce synchronous motor, and the rotor of permagnetic synchronous motor is the vitals affecting motor cost.
Summary of the invention
The purpose of this utility model is to provide a kind of permanent-magnetic synchronous motor rotor, and it has is easy to assembling, lower-cost feature.
The technical scheme is that permanent-magnetic synchronous motor rotor of this utility model, including rotating shaft and permanent magnet, the both ends of this rotating shaft are respectively equipped with a bearing, the outside of described rotating shaft is fixed with a urceolus coaxial with this rotating shaft by rigid link, simultaneously, the middle part of this rotating shaft is provided with the even number degree of depth inner card cage less than 3mm along the circumferential surface of this rotating shaft, the inwall of this urceolus is provided with the even number degree of depth exterior bayonet slot less than 3mm along the inwall circumferential surface of this urceolus, inner card cage and exterior bayonet slot are corresponding between two, in corresponding inner card cage and exterior bayonet slot, card has a permanent magnet, permanent magnet is wedge shaped, and between adjacent permanent magnet, there is gap, viscose glue it is filled with in gap, and, rotating shaft, rigid link, urceolus adopts 316L alloy material to prepare, permanent magnet adopts Nd-Fe-B permanent magnet.
Being arranged with gear in described rotating shaft, this gear is between permanent magnet and one of them bearing.
This utility model is compared to the prior art advantageously: be easy to assembling, less costly. The permanent-magnetic synchronous motor rotor of the present utility model mode fixed permanent magnet by clamping, and the degree of depth of exterior bayonet slot and inner card cage is all shallower, just with preparation and assembling. Meanwhile, by the firm permanent magnet of viscose glue, make the performance of PM rotor to reduce, and bearing is arranged at inside bearing, it is simple to the stress of assembling and balancing rotor.

Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 and Fig. 2: permanent-magnetic synchronous motor rotor, including rotating shaft 10 and permanent magnet 40. The both ends of this rotating shaft 10 are respectively equipped with a bearing 60.
Further saying, the outside of this rotating shaft 10 is fixed with a urceolus 30 coaxial with this rotating shaft 10 by rigid link 20. That is, this rotating shaft 10 is positioned on the axial line of this urceolus 30, and those rigid link 20 are played a supporting role, and the two ends of rigid link 20 can be individually fixed on this rotating shaft 10 and this urceolus 30 by the mode welded. Meanwhile, the middle part of this rotating shaft 10 is provided with the even number degree of depth inner card cage 11 less than 3mm along the circumferential surface of this rotating shaft 10, and the inwall of this urceolus 30 is provided with the even number degree of depth exterior bayonet slot 31 less than 3mm along the inwall circumferential surface of this urceolus 30. Inner card cage 11 and exterior bayonet slot 31 are corresponding between two, and corresponding inner card cage 11 and the interior card of exterior bayonet slot 31 have a permanent magnet 40, and permanent magnet 40 is wedge shaped. That is, the inner of permanent magnet 40 is stuck in the inside and outside end of inner card cage 11 and is stuck in exterior bayonet slot 31. There is between adjacent permanent magnet 40 gap 32, in gap 32, be filled with viscose glue 50. Obviously, viscose glue 50 can solidify over time. And, rotating shaft 10, rigid link 20, urceolus 30 adopts 316L alloy material to prepare, permanent magnet 40 adopts Nd-Fe-B permanent magnet. So, owing to urceolus 30 is prone to be indirectly fixed to outside this rotating shaft 10 by the mode welded, the degree of depth of inner card cage 11 and exterior bayonet slot 31 is all shallower, when assembling, only need permanent magnet 40 is stuck in corresponding position, afterwards glue is packed in those gaps 32, extremely simple.
Continuing to optimize, this rotating shaft 10 is arranged with gear 70, this gear 70 is between permanent magnet 40 and one of them bearing 60. So, it is simple to stress balance, it is not necessary to limit the position of the parts such as bearing, gear extremely accurately, reduce further assembly difficulty.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
