In order to protect the integrality of magnet structure, threaded hole or card slot etc. cannot be generally set with linkage function on magnet Structure generally require and be first adhered to one for multiple magnetic yokes as one group therefore for the rotor of generator in the prior art On a carrier board, then carrier board is installed to the mounting surface of magnetic yoke again.However, since magnet and carrier board use bonding Mode connects, and will lead to magnet and is not easy to be removed from carrier board, difficulty is larger when needing replacing some magnet.

The fixation device that the embodiment of the present application provides a kind of magnet is as depicted in figs. 1 and 2, which includes: multiple First connector 1 and at least two pressing pieces 2, pressing piece 2 for being connected to specified mounting surface by the first connector 1, often A pressing piece 2 includes at least one pressure surface 21.

In the embodiment of the present application, specified mounting surface refers to the mounting surface 101 of magnetic yoke 100, which is installed to After the mounting surface 101 of magnetic yoke 100, one group of magnet 200 can be limited in the adjacent of two adjacent pressing pieces 2 with being arranged successively Between two pressure surface 21, as shown in figure 3, first pressing piece 2 is connected by the first connector 1 and the mounting surface 101 of magnetic yoke 100 It connects, so that the interval of two neighboring pressure surface 21 of two neighboring pressing piece 2 and opposite, then one group of magnet 200 is placed on adjacent Two pressing pieces 2 two neighboring pressure surface 21 between, then adjust the first connector 1 make pressing piece 2 compress magnet 200, i.e., magnet 200 is mounted on to the mounting surface 101 of magnetic yoke 100；When needing to remove magnet 200, by adjusting the first connector 1 Reduce pressing piece 2 to the pressure of magnet 200, it, can be by magnet 200 from two adjacent pressing pieces 2 so that magnet 200 loosens Two neighboring pressure surface 21 between take out.Fixed device provided by the embodiments of the present application mounts and dismounts the behaviour of magnet 200 Make it is simple and easy, reduce replacement magnet 200 when work difficulty.

It should be noted that as shown in Figures 3 to 5, one group of magnet 200 being limited in adjacent two with being arranged successively and is applied Refer specifically between the two neighboring pressure surface 21 of casting die 2: one group of magnet 200 forms a line along the extending direction of pressure surface 21, The two neighboring pressure surface 21 of two adjacent pressing pieces 2 compresses each magnet 200 simultaneously, enables each 200 phase of magnet It is constant to 101 holding position of mounting surface of magnetic yoke 100.

Optionally, in the embodiment of the present application, the first connector 1 can use bolt.Pressing piece 2 is equipped with screw thread via hole 22, The mounting surface 101 of magnetic yoke 100 is accordingly equipped with threaded hole, the screw thread via hole 22 of screw bolt passes pressing piece 2 and magnetic yoke 100 Threaded hole adjusts pressing piece 2 by rotation bolt to the big of the pressure of magnet 200 so that pressing piece 2 to be connected in magnetic yoke 100 It is small.

In order to enable one group of magnet 200 can be along the axial alignment of magnetic yoke 100, the pressure surface 21 of pressing piece 2 should be along magnetic Yoke 100 it is axially extending.

Optionally, in the embodiment of the present application, the pressing piece 2 is bar shaped block, and the pressure surface 21 is the flat of pressing piece 2 Row is in the side of its length extending direction.When installing pressing piece 2, circumferentially-spaced row of at least two pressing pieces 2 along magnetic yoke 100 Column, and 2 length direction of pressing piece is made to be parallel to the axial direction of magnetic yoke 100, at this point, for the adjacent of two adjacent pressing pieces 2 The mounting surface 101 of two pressure surface 21, the two neighboring pressure surface 21 and magnetic yoke 100 constitutes a type chamber, and the type chamber is along magnetic yoke 100 it is axially extending, correspondingly, one group of magnet 200 peace can form a line along the axial direction of magnetic yoke 100, and to be placed in the type intracavitary, And each magnet 200 in one group of magnet 200 be at least partially situated at the type it is intracavitary and with constitute the type chamber pressure surface 21 contacts enable 200 opposing yoke 100 of magnet fixed.

The rotor of generator generally comprises internal rotor or outer rotor.For the magnetic yoke 100 of outer rotor, mounting surface 101 is The inner wall of magnetic yoke 100；For the magnetic yoke 100 of internal rotor, mounting surface 101 is the outside wall surface of magnetic yoke 100.It should illustrate It is that magnetic yoke 100 is generally cylindrical in shape, in the embodiment of the present application, inner wall refers to the circumferential surface of 100 inside of magnetic yoke, and outside wall surface refers to The circumferential surface in 100 outside of magnetic yoke.Magnet 200 also may include various shapes, for example, for the magnet being mounted in magnetic yoke 100 200, the axial section perpendicular to magnetic yoke 100 can be rectangle, trapezoidal or arc ring etc..For perpendicular to magnetic yoke 100 Axial section is trapezoidal magnet 200, and side wall where the trapezoidal waist is the stress surface 201 of magnet 200, the stress surface 201 It is contacted for the pressure surface 21 with pressing piece 2.It will be below outer rotor, magnet 200 perpendicular to magnetic yoke 100 using the rotor of generator Axial section when being trapezoidal for, introduce a kind of specific design feature of fixed device.

In order to install magnet 200 securely, for the two neighboring pressure surface 21 of two neighboring pressing piece 2, such as Fig. 2 Shown, the virtual extended planar of two pressure surface 21 should intersect at side of the mounting surface 101 far from pressing piece 2.It can manage The type chamber that Xie Wei, the two neighboring pressure surface 21 of two neighboring pressing piece 2 and the mounting surface 101 of magnetic yoke 100 collectively form can Think dovetail groove profile chamber 6, and the dovetail groove profile chamber 6 is directed toward the first of separate pressing piece 2 along by the mounting surface 101 of magnetic yoke 100 Direction gradually tapers up.When installing magnet 200, first two pressing pieces 2 are bolted in magnetic yoke 100, so that adjacent After the two neighboring pressure surface 21 of two pressing pieces 2 and the mounting surface 101 of magnetic yoke 100 collectively form dovetail groove profile chamber 6, then will Magnet 200 is put into dovetail groove profile chamber 6, and two stress surfaces 201 of magnet 200 press with two of composition dovetail groove profile chamber 6 respectively The fitting contact of face 21, magnet 200 are limited along the movement of first direction, and screwing bolts make pressing piece 2 compress magnet 200, Complete the installation of magnet 200.

In order to constitute dovetail groove profile chamber 6, in the embodiment of the present application, as shown in fig. 7, pressing piece 2 prolongs perpendicular to its length Stretching the section in direction is trapezoidal, side of the pressure surface 21 where trapezoidal waist.Pressing piece 2 is installed to the installation of magnetic yoke 100 When face 101, the mounting surface 101 of upper bottom surface 23 and magnetic yoke 100 where trapezoidal upper bottom edge is opposite, and than trapezoidal bottom institute Bottom surface 24 closer to the mounting surface 101 of magnetic yoke 100, at this time the two neighboring pressure surface 21 of two neighboring pressing piece 2 with And the mounting surface 101 of magnetic yoke 100 can collectively form dovetail groove profile chamber 6.
