In the present invention in order to ensure that permanent-magnetic clamp has the suction-combining force entering by force, be convenient to again processing and manufacturing, and cost is lower simultaneously, preferred technical scheme also has, and the permanent-magnetic clamp 2 in described second step is a kind ofly to make with samarium-cobalt material.
Embodiment 1
Mount pad 1 can be formed by 20 steel processing and fabricatings, on the end face of ring flange 5 that is provided with boss, there is the screw of 4 M10, boss is that the external diameter of φ 60 × 3 coordinates with the Internal hole positioning of permanent-magnetic clamp 2, can be used as the use of the location of permanent-magnetic clamp on mount pad, endoporus φ 4 is coaxial with boss external diameter φ 60 simultaneously, 40 sections of matched in clearance of φ with armature spindle 4, the other end external diameter of mount pad 1 is equivalent to a handle, rear end protruding also or must gram bore portion be while preventing manual operations, to be subject to the impact of strong magnetic force and landing, permanent-magnetic clamp 2 and magnetic bearing rotor 3 clashed into mutually and damage permanent-magnetic clamp.
Copper bolt 7 is used for adjusting the secure localization of permanent-magnetic clamp 2 and mount pad 1, and can effectively make permanent-magnetic clamp 2 separate with mount pad 1.
Permanent-magnetic clamp 2 is a kind ofly to make with samarium-cobalt material, has very strong magnetic after magnetizing.
Magnetic bearing rotor 3 is to be formed by stacking by many silicon steel sheets and two end clamp plates 8, coordinates by the large magnitude of interference with armature spindle 4, needs shrink-on just can complete.
Armature spindle 4 is high-speed rotating shafts of flywheel energy storage wind-driven generator Flywheel, and its material is non-magnetic stainless steel.
Its installation steps are:
The first step faces up the locating flange dish 5 on mount pad 1, handle end can be fixed on bench vice, the copper bolt 7 flange surface 6 ~ 8mm that back-outs, hand-held permanent-magnetic clamp 2 moves to copper bolt 7 from top by permanent-magnetic clamp, feel has obvious magneticaction, manually adjust, make the positioning convex ring φ 60 on the basic alignment flange dish of its endoporus, as shown in Figure 1.
Four copper bolts 7 are synchronously adjusted downwards, can suitably manually be adjusted the aligned position of permanent-magnetic clamp 2 holes and bulge loop simultaneously, until permanent-magnetic clamp and bulge loop and flange surface are located adhesive completely, as shown in Figure 2 for second.
The 3rd step is because the cooperation in permanent-magnetic clamp 2 and magnetic bearing rotor 3 holes is interference fit, and the waste heat while utilizing magnetic bearing rotor 3 with armature spindle 4 hot jacket, gets ready in advance, in the time of 150 DEG C, permanent-magnetic clamp 2 hot jackets is packed in the hole of magnetic bearing rotor 3, as shown in Figure 3,4.
The 4th step is after lowering the temperature, permanent-magnetic clamp 2 is clamped by magnetic bearing rotor 3, if at this moment directly mount pad 1 upwards generally cannot be removed, because permanent-magnetic clamp 2 can be very large with the suction-combining force of 5, mount pad ring flange, only have with 4 copper bolts 7 stubborn downwards, allow permanent-magnetic clamp 2 and the flange surface of mount pad 1 have the distance of 6 ~ 8mm, now can like a cork mount pad 1 be removed between permanent-magnetic clamp 2 and armature spindle 4, as shown in Figure 5.
The feature of this assembly method is
If do not use mount pad 1, that uncontrollable its magnet ring 2 arrives correct installation site by hand grip, and because magnetic force is excessive, probably cause permanent-magnetic clamp 2 and magnetic bearing rotor 3 to clash into, cause permanent-magnetic clamp 2 breakages and scrap, be difficult to for the moment damaged magnet ring to push aside, owing to utilizing the time-out of waste heat, hot jacket method is counted out.And adopt mount pad 1 to carry out hot jacket installation to permanent-magnetic clamp 2, avoid the generation of above situation completely.
Because permanent-magnetic clamp 2 is interference fit with magnetic bearing rotor 3, must be within the extremely short time, in the time of 150 DEG C of suitable temperature, just can carry out hot jacket, grab operation if utilize hand, grab operation and center not in placely due to the effect hand of magnetic force, often lose operable time, or permanent-magnetic clamp 2 enters half just by locking, and can only scrap magnet ring, sometimes also can cause burning and crushing of hand.And adopt mount pad 1 to carry out hot jacket installation to permanent-magnetic clamp, owing to permanent-magnetic clamp 2 being pull-in on mount pad 1 before magnetic bearing rotor 3 and armature spindle 4 hot jackets, get ready in advance, in the time waiting for 150 DEG C of suitable temperature, can immediately permanent-magnetic clamp 2 be in place, its reason is to have positioning and guiding, the handle of mount pad 1 other end only need be controlled the downward speed of magnet ring and effectively overcome downward magnetic force, concrete operations facts have proved, utilize mount pad 1 to install permanent-magnetic clamp 2, convenient, reliable, safety, be successfully completed rate 100%.
This is a kind of assembly method of plane magnet ring, if the installation of anchor ring magnet ring can have been gone by the method too, only plane boss location need be made into arc surface location; If large-scale magnet ring is installed, its location and installation principle is all identical, and just magnet ring substitutes manually to advance to install with hydraulic damping propulsive mechanism when mounted and realizes.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
