1 to Figure 12 installation side for specifically describing the outer magnetic ring of embodiment according to a second aspect of the present invention below in conjunction with the accompanying drawings
Method.
As shown in figure 8, the installation method of outer magnetic ring according to the ... of the embodiment of the present invention uses the outer magnetic ring formula of above-described embodiment
The installation tool 200 of the outer magnetic ring of Permanent-magnet bearing, the installation method include the following steps:
S1, guide ring is installed on the lower surface of magnet yoke ring and limits outer magnetic ring guiding with the cooperation of outer magnetic ring mounting groove
Slot;
S2, support backing plate is located at the notch of outer magnetic ring guide groove, and the lower surface of support backing plate is made to be led with outer magnetic ring
Upper surface to slot is concordant;
S3, by each permanent magnets successively being inserted radially into outer magnetic ring guide groove to precalculated position along outer magnetic ring guide groove;
S4, permanent magnets are driven to be fully inserted in outer magnetic ring mounting groove along the radial direction of outer magnetic ring guide groove by actuator;
S5, actuator, support backing plate and guide ring are dismantled successively, and shield magnet ring is mounted on magnet yoke ring with fixed outer magnetic
Ring.
Specifically, with reference to Fig. 3 and Fig. 4, first by guide ring be mounted on magnet yoke ring lower surface and with the coaxial cloth of magnet yoke ring
It sets, it can be with the annular space of grafting magnet yoke ring, while to fan-shaped permanent magnets to be cooperatively formed between outer magnetic ring mounting groove
Guiding and limit are played the role of in installation, secondly, by support backing plate and magnet yoke ring coaxial package, and are located at outer magnetic ring guide groove
Notch at so that support the lower surface of backing plate and the upper surface of outer magnetic ring guide groove in the same plane, not only can be
Permanent magnets are supported when installation sector permanent magnets, using support backing plate, and support backing plate can be utilized to be axially formed with one
Determine the magnetic circuit of magnetic resistance so that generate magnetic attraction appropriate between permanent magnets, support backing plate and magnet yoke ring, stablize point of outer magnetic ring
Cloth, third, by the permanent magnets of each sector along outer magnetic ring guide groove so that the inner arc of fan-shaped permanent magnets reaches pre-determined bit
It sets, consequently facilitating permanent magnets are in circumferential, radial position adjustment.
Further, with reference to Fig. 5, drive permanent magnets gradually small size along the radial direction of outer magnetic ring guide groove by actuator
Degree is close to the flange outer circumference surface of magnet yoke ring, the gap reduction between the inner arc of the permanent magnets of the flange and sector of magnet yoke ring
When being 0, the complete grafting of permanent magnets enters in outer magnetic ring mounting groove.
Finally, guide ring and magnet yoke ring are fastenedly connected first with reference to Fig. 5 to Fig. 7 so that guide ring will be inserted in outer magnetic
Outer magnetic ring in ring guide groove is clamped in the lower surface of magnet yoke ring;Secondly, actuator, support backing plate and guide ring are dismantled successively,
And it is mounted on the inner edge of annular outer magnetic ring, peripheral end portion by magnet ring is protected, to which outer magnetic ring to be fixed on to the lower surface of magnet yoke ring.
The installation method of outer magnetic ring according to the ... of the embodiment of the present invention as a result, by using the outer magnetic described in above-described embodiment

Position so that the permanent magnets of multiple sectors are initially arranged along annular radial shape, to be formed between an adjacent fan-shaped permanent magnets
The outer magnetic ring for having larger gap, the movement of fan-shaped permanent magnets is constrained using guide ring, so be effectively prevented from permanent magnets overturning,
Repel, impact wreckage magnet, meanwhile, fan-shaped permanent magnets are squeezed by a small margin using actuator is synchronous successively so that fan-shaped is outer
Diameter is gradually reduced in the annular outer magnetic ring of magnet ring permanent magnets splicing, until between the circumferential direction between the adjacent permanent magnet block of composition outer magnetic ring
Gap disappears, and forms gap as 0 annular outer magnetic ring, is closed to avoid opening up installation during the installation process being seriously affected with threaded hole
Magnetic circuit is closed, and then increases the bearing capacity of outer magnetic ring formula Permanent-magnet bearing.
In certain specific embodiments of the invention, guide ring includes being oriented to inner ring 21 and guiding outer shroud 23, in guiding
The inner ring of ring 21 is detachably connected with magnet yoke ring 8, and the outer diameter for being oriented to inner ring 21 is less than the outer diameter of outer magnetic ring mounting groove, is oriented to outer
The inner ring of ring 23 is detachably connected with the outer ring for being oriented to inner ring 21, and the outer diameter for being oriented to outer shroud 23 is equal to the outer of outer magnetic ring mounting groove
Diameter;
As shown in figure 9, step S1 includes:S11, will be oriented to inner ring and be oriented to outer shroud be connected to an entirety;S12, it will lead
The entirety being connected to inner ring and guiding outer shroud is coaxially mounted on magnet yoke ring and limits outer magnetic with the cooperation of outer magnetic ring mounting groove
Ring guide groove.
With reference to Fig. 3, guide ring includes being oriented to inner ring 21 and being oriented to outer shroud 23, is oriented to the outer ring of inner ring 21 and is oriented to outer shroud 23
Inner ring between by 22 detachably connected fastening of hexagon socket head cap screw, to form an entirety, be oriented to the inner ring of inner ring 21
It is removably mounted on the upper of magnet yoke ring 8, wherein the race diameter for being oriented to inner ring 21 is less than the outer diameter of outer magnetic ring mounting groove, leads
Race diameter to outer shroud 23 is equal with the outer diameter of outer magnetic ring mounting groove, to which the permanent magnets 111 for ensureing fan-shaped can insert completely
It is connected in outer magnetic ring mounting groove, and then ensures that the magnet of outer magnetic ring 11 such as avoids being collided with the damages.
Specifically, the step S1 in the installation method of outer magnetic ring is:It will be oriented to inner ring first and be oriented to outer shroud and be connected to become
Secondly whole guide ring structure, then is mounted on guiding on magnet yoke ring and coaxially arranged, whole with magnet yoke ring by one entirety
Ring cooperatively forms an annular space (i.e. outer magnetic ring guide groove) for placing outer magnetic ring with magnet yoke ring.
Wherein, the height of outer magnetic ring guide groove can be slightly above the thickness of permanent magnets, not only can be in order to permanent magnets ring
Shape and radial direction are adjusted, and driving permanent magnets can be facilitated to be fully inserted into outer magnetic ring guide groove.
