Description
Technical field:
The utility model relates to a kind of outer rotor tractor permanent magnet technique for fixing.
Background technology
The permanent magnet fixed form of existing permanent-magnet synchnorous gearless dragging machine external rotor is all use glue to paste in yoke usually, temperature due to permanent magnet position when traction machine works is general all between 100 DEG C-150 DEG C, if glue high temperature failure, permanent magnet then can be caused to come off, cause elevator safety accident.Chinese patent " permanent magnet fixing device of a ZL2010201735159(outer-rotor structure) " process a fixing hole at permanent magnet center, utilize screw that permanent magnet is fixed in yoke, but Problems existing is: the material due to permanent magnet is powder sintered, the heart processes a through hole wherein, causes it to be easy to ftracture at central hole location.
Summary of the invention
The utility model object is just to provide a kind of reasonable stress, and structure is simple, and cost is low, and permanent magnet is not easy cracking and assembles outer rotor tractor magnet fixing structure of permanent very easily.
The utility model object is achieved in that and comprises external rotor, permanent magnet, permanent magnet parting bead, permanent magnet pressing plate, the annulus madial wall of external rotor is provided with fall step-like yoke, the step end face of the step-like yoke that falls is indent inclined-plane, the inclined-plane that wherein one end of permanent magnet and wherein one end of permanent magnet parting bead all match in the step end face in indent inclined-plane with the step-like yoke that falls also injects in the step end face in indent inclined-plane, permanent magnet, the high temperature resistant glue of permanent magnet spacer bar is pasted onto in step-like yoke, permanent magnet pressing plate comprises annular fixing plate, be arranged on the convex pressing plate on annular fixing plate inside circular edge, on the annulus end face that the annular fixing plate of permanent magnet pressing plate is fixed on external rotor and between the step end face that permanent magnet and permanent magnet parting bead are positioned at step-like yoke and annular fixing plate, the convex pressing plate of permanent magnet pressing plate is pressed on the permanent magnet parting bead other end, permanent magnet is in the step-like yoke in whereabouts of annulus madial wall by dovetail configuration, permanent magnet being fixed on external rotor.
Here, in order to the rotation preventing convex pressing plate from affecting external rotor, the other end of permanent magnet parting bead is provided with whereabouts step or inclined-plane.
beneficial effect
1 permanent magnet uses glue to add the fixing dual fixed form of machinery and is fixed in yoke, effectively prevents permanent magnet and permanent magnet spacer bar from coming off.
2 permanent magnet spacer bars ensure that permanent magnet is uniformly distributed and prevents lateral displacement.
3 permanent magnet pressing plates ensure that permanent magnet and permanent magnet spacer bar can not length travels.
Therefore, the utility model has reasonable stress, and structure is simple, and cost is low, and permanent magnet is not easy cracking and assembles advantage very easily.
