Figure is labeled as:
1, unshakable in one's determination;11, passage;2, studs;21, screw;3, winding.
Detailed description of the invention
In order to make it easy to understand, the invention will be further described below in conjunction with the accompanying drawings.
See the primary schematic diagram that Fig. 1~Fig. 4, Fig. 1 are a kind of linear electric motors that the present invention provides, Fig. 2 Be the B of Fig. 1 to sectional view, Fig. 3 is the top view of Fig. 1, Fig. 4 be part 2 in Fig. 2 vertical view signal Figure.
The primary of a kind of linear electric motors that the present invention provides includes the iron core 1 being stacked by punching, runs through ferrum The studs 2 in the yoke portion of the heart 1, and it is embedded in the winding 3 in the line embedding groove of unshakable in one's determination 1, at least one Studs 2 is provided with the screw 21 for connecting screw rod, screw 21 extend perpendicularly to studs The axis direction of 2, the yoke portion of unshakable in one's determination 1 is provided with, away from one end of winding 3, the passage 11 passed for screw rod.
The primary of the linear electric motors that the present invention provides is provided with screw 21 at least one studs 2, 1 yoke portion unshakable in one's determination is provided with the passage 11 corresponding with screw, and screw rod therefore can be utilized directly by linear electric motors Primary and magnetic suspension train suspension rack couples together, and eliminates the connecting portion that the weight such as olate-steel case are bigger Part, so the present invention is capable of and mounting structure relatively simple between suspension rack, zero needed for installation Part weight is less.
On each studs 2 being provided with screw 21, screw 21 quantity can be 2~4.See figure 2, in the present embodiment, on each studs 2 being provided with screw 21, screw 21 quantity is 2, certainly, Other quantity can also be selected as required.In order to add the reliability of strong ties, multiple being provided with can be set The studs 2 of screw 21, studs 2 quantity being provided with screw 21 is generally 4~8.
Punching is mainly compressed by the effect of studs 2 with nut screw connection, is provided with the double end spiral shell of screw 21 Post 2 also has the primary effect hanging linear electric motors, therefore to improve the reliability hung, permissible Increasing the contact area of unshakable in one's determination 1 and the studs 2 being provided with screw 21, one preferably mode is, will The middle cross section of the studs 2 being provided with screw 21 is changed into rectangle, other shapes such as trapezoidal by circle, Seeing Fig. 4, in the present embodiment, studs 2 two ends being provided with screw 21 are screwed cylinder, Middle part is cuboid, and screw 21 is opened in the middle part of studs 2, and the bearing of trend of screw 21 hangs down Straight in the surface of studs 2.
In view of to be provided for the passage 11 through screw rod in the yoke portion of unshakable in one's determination 1, therefore at corresponding screw The position of 21, punching should arrange breach, and the punching jaggy of multiple tools overlaps together, by breach shape Become passage 11.It can be appreciated that need to make two kinds of punchings, a kind of breach being provided with for forming passage 11, Another kind does not then have breach.See Fig. 2 and Fig. 3, in order to simplify the production process of unshakable in one's determination 1, reduce difficulty, Passage 11 can run through the yoke portion of unshakable in one's determination 1 along studs 2 axis direction, and the width of passage 11 is little In the middle part of studs 2 along the size of passage 11 width.It is pointed out that in order to stress is equal Weighing apparatus, the middle part cross-section center line of the studs 2 on screw 21 bearing of trend and passage 11 cross section Centrage overlaps, as shown in Figure 1.
The present invention also provides for a kind of primary linear electric motors that have employed the present invention, and one have employed this The magnetic suspension train of the linear electric motors of invention.
