Abstract
The invention discloses a device for preventing magnetic attraction in permanent-magnetic synchronous electric main shaft assembling. The device comprises a gantry lifting frame (1), a movable working rack (7) and a lifting tooling (3) connected with a shaft, wherein a fixed guide sleeve (9) is arranged in the center of the movable working rack (7); the gantry lifting frame (1) is arranged right above the movable working rack (7); a manual lifting block (2) is arranged under the gantry lifting frame (1); and the lifting tooling (3) connected with the shaft is arranged under the manual lifting block (2). The device disclosed by the invention has the advantage that permanent-magnetic synchronous electric main shafts are easily assembled to preset parts.
Description
Technical field
The present invention relates to a kind of permanent-magnet synchronous electricity spindle mounted technology, especially relate to the anti-magnetic attraction device of a kind of permanent-magnet synchronous electricity spindle mounted.
Background technology
The rotor material of permanent magnet synchronous high-speed electricity main shaft is a high-performance rare-earth permanent magnet material, and air-gap field is produced by permanent magnet excitation, so the Permanent Magnet and Electric main shaft compares with high-speed asynchronous electric main shaft, and efficient and power factor are all very high.The torque of high-speed asynchronous electric main shaft produces through slip; And slip and rotor current and rotor loss are closely related, and when high-speed cruising, rotor loss is serious; Cause the efficient of high-speed asynchronous electric main shaft very low, thus the very high mechanical strength that influences rotor of temperature of rotor during long-play.
In actual use; Compare with alternating current asynchronous electricity main shaft; Permanent-magnet synchronous electricity main shaft also has characteristics; The minimum operating speed that is exactly it can be low to moderate hundreds of even tens commentaries on classics, and the minimum operating speed of alternating current asynchronous electricity main shaft can't satisfy complicated day by day processing conditions generally on one or two thousand right sides of turning left.But because the rotor material is that high-performance rare-earth permanent magnet material brings an insurmountable problem of the common assembly method of usefulness; The rotor magnetic attraction is very big; Rotor is through stator hole the time, and the rotor permanent magnet appearance is directly just inhaled on the stator hole inner surface, for just can't move with manpower after large-scale permanent-magnet synchronous armature spindle and the stator adhesive at all; Can't armature spindle be assembled to predetermined position, will damage commentaries on classics, stator and other contacted parts through the hard dress of mechanical means.
Summary of the invention:
The purpose of this invention is to provide the anti-magnetic attraction device of a kind of permanent-magnet synchronous electricity spindle mounted, make permanent-magnet synchronous electricity main shaft be easy to be assembled to predetermined position.
The present invention is achieved in that the anti-magnetic attraction device of a kind of permanent-magnet synchronous electricity spindle mounted; Comprise gallows frame, removable Working gantry, be connected with axle and lift by crane frock; It is characterized in that: described removable Working gantry center is provided with the fixed guide cover; Be provided with gallows frame directly over the removable Working gantry, be provided with manual tackles below the gallows frame, manually be provided with below the tackles and a lifting frock that is connected.
The present invention can make permanent-magnet synchronous electricity main shaft be easy to be assembled to predetermined position.
Description of drawings:
Fig. 1 is a structural representation of the present invention:
Among the figure 1, gallows frame, 2, manual tackles, 3, the lifting frock, 4, the permanent-magnet synchronous armature spindle; 5, the axle front end connects adapter sleeve, and 6, permanent-magnet synchronous casing, stator line bag half assembly, 7, removable Working gantry; 8, guiding mandrel, 9, the fixed guide cover, 10, trip bolt.
Embodiment:
Below in conjunction with accompanying drawing the present invention is described further:
With reference to accompanying drawing; The anti-magnetic attraction device of a kind of permanent-magnet synchronous electricity spindle mounted; Comprise gallows frame 1, removable Working gantry 7, be connected lifting frock 3 with axle, it is characterized in that: described removable Working gantry 7 centers are provided with fixed guide cover 9, are provided with gallows frame 1 directly over the removable Working gantry 7; Be provided with manual tackles 2 below the gallows frame 1, manually be provided with the lifting frock 3 that is connected with axle below the tackles 2.During practical implementation; The 1st step was assemblied in permanent-magnet synchronous casing, stator line bag half assembly 6 on the movable fixed casing Working gantry 7 earlier; The 2nd step will lift by crane frock 3, permanent-magnet synchronous armature spindle 4, will be connected adapter sleeve 5 with a front end, the mandrel 8 usefulness trip bolts 10 that lead connect into an integral body; The 3rd step will be movably fixedly gallows frame 1 move to above movable fixed casing Working gantry 7 centers then fixedly gallows frame 1; The 4th step hung 500 kilograms of manual tackleses 2 to fixing gallows frame; Then the most significant end of the permanent-magnet synchronous armature spindle connecting assembly body that assembles is sling; Guiding mandrel in permanent-magnet synchronous armature spindle connecting assembly body lower end is put into from the stator hole center of permanent-magnet synchronous casing, stator line bag half assembly and is winched to fixed guide and overlap 9 upper end holes; This moment, the armature spindle permanent magnet was also not approaching with the stator hole edge, when waiting armature spindle permanent magnet in the more than half entering fixed guide covers 9 of whole permanent-magnet synchronous armature spindle connecting assembly body near the stator hole edge, though this moment the armature spindle permanent magnet with the very big magnetic attraction of stator hole edge generation; But fairlead fixed rotor axle permanent magnet and stator are not inhaled owing to be fixed, and utilize gravity and manpower to be easy to the permanent-magnet synchronous armature spindle is installed to the position that requires again.
