Abstract
The invention relates to improvements of a motor, in particular to a permanent magnet matching structure of a synchronous motor. The permanent magnet matching structure comprises a hub, a permanent magnet, and a permanent magnet press plate which is arranged on one end face of the hub. A groove is formed in a position, in a joint position of the hub and one end portion of the permanent magnet, of the hub and corresponds to the joint part of the other end portion of the permanent magnet and the permanent magnet press plate. A chamfer is arranged in a position, in the joint part, of the permanent magnet press plate. The chamfer and the inner surface of the hub jointly form a groove. The two grooves are opposite to each other so as to jointly form a permanent magnet installation position. The permanent magnet is inlaid in the permanent magnet installation position so as to be fixed to the inner surface of the hub. The permanent magnet matching structure is simple and reasonable in structural design, remarkably reduces the processing amount of drilling, and reduces cost. Moreover, the risk that the permanent magnet is crushed does not exist. The permanent magnet can be installed and detached conveniently.
Description
Technical field
The present invention relates to a kind of improvement of motor, relate in particular to a kind of permanent magnet fit structure of synchronous machine.
Background technology
In existing outer rotor permanent magnet motor, the permanent magnet fit structure as shown in Figure 1, 2, permanent magnet 3 sticks on wheel hub 1 by glue, then establish hole in permanent magnet, permanent magnet pressing plate 2 is located in the permanent magnetism body opening, by screw 4 locking permanent magnet pressing plates 2 and wheel hub 1, permanent magnet 3 is fixed on to hub surface.The mounting structure of existing this permanent magnet exists following not enough, need to bore a lot of holes on wheel hub, can increase processing cost like this; The permanent magnet pressing plate need to be made by the non-magnet material that certain degree of hardness is arranged, and is generally to use brass, and cost compare is high; Permanent magnet is likely because coupling mechanism force is too large and crushed.
Summary of the invention
The object of the invention just is to provide that a kind of cost is low, and processing capacity is few, and the permanent magnet fit structure of safe and reliable synchronous machine.
The present invention seeks to realize like this:
A kind of permanent magnet fit structure of synchronous machine, comprise wheel hub, permanent magnet, the permanent magnet pressing plate, described permanent magnet pressing plate is located at the wheel hub end face, the bonding station of described wheel hub and permanent magnet one end, the wheel hub of this bonding station is provided with a groove, the junction surface of corresponding permanent magnet the other end and permanent magnet pressing plate, the permanent magnet pressing plate at this junction surface is provided with a chamfering, the common groove that forms of this chamfering and hub inner surface, two grooves form the permanent magnet installation position relatively jointly, and permanent magnet is embedded in the permanent magnet installation position realizes that permanent magnet is fixed in hub inner surface.
Technique scheme also can be made to the following further improve.
Being the dovetail groove shape between described permanent magnet installation position and permanent magnet coordinates.
Between described permanent magnet pressing plate and wheel hub, be screwed.
Structural design advantages of simple of the present invention, significantly reduced the Drilling operation amount, reduced cost.And can there be crushed risk in permanent magnet yet.The dismounting of permanent magnet all facilitates.
The accompanying drawing explanation
Fig. 1 is existing permanent magnet mounting structure schematic diagram.
Fig. 2 is the A-A cutaway view.
Fig. 3 is permanent magnet fit structure schematic diagram of the present invention.
Fig. 4 is the local enlarged diagram figure of Fig. 3.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 3,4, a kind of permanent magnet fit structure of synchronous machine, mainly be comprised of wheel hub 1, permanent magnet 2, permanent magnet pressing plate 3 structure of the present invention.Described permanent magnet pressing plate 3 is located at wheel hub 1 end face, and both are by screw 4 lockings.The bonding station of described wheel hub and permanent magnet one end, the wheel hub of this bonding station is provided with a v-depression, the permanent magnet pressing plate at the ，Gai junction surface, junction surface of corresponding permanent magnet the other end and permanent magnet pressing plate is provided with a chamfering 5, the common groove that forms of this chamfering and hub inner surface.Two grooves form the permanent magnet installation position relatively jointly, and the permanent magnet two ends respectively form respectively an oblique angle.First bonding by glue between permanent magnet and wheel hub, then permanent magnet one end is pushed in v-depression, then the permanent magnet pressing plate is arranged on to the wheel hub end face, compress this end of permanent magnet, be the dovetail groove shape between permanent magnet installation position and permanent magnet and coordinate, permanent magnet is embedded in the permanent magnet installation position and realizes that permanent magnet is fixed in hub inner surface like this.Therefore, when glue lost efficacy, permanent magnet just there is no fear of breaking away from the permanent magnet installation position.
Claims (3)
1. the permanent magnet fit structure of a synchronous machine, comprise wheel hub, permanent magnet, the permanent magnet pressing plate, it is characterized in that: described permanent magnet pressing plate is located at the wheel hub end face, the bonding station of described wheel hub and permanent magnet one end, the wheel hub of this bonding station is provided with a groove, the junction surface of corresponding permanent magnet the other end and permanent magnet pressing plate, the permanent magnet pressing plate at this junction surface is provided with a chamfering, the common groove that forms of this chamfering and hub inner surface, two grooves form the permanent magnet installation position relatively jointly, permanent magnet is embedded in the permanent magnet installation position realizes that permanent magnet is fixed in hub inner surface.
