Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing
Describe in detail as follows:
Referring to Fig. 1, a kind of electric lost dental inlay permanent magnet brake, including ring gear 1, connection dish 2, armature 3, permanent magnet
Dish 8 and yoke；Described ring gear 1 one side end face is provided with end-tooth, described armature 3 be positioned at described ring gear 1 inner circumferential and with institute
Stating ring gear 1 affixed, described connection dish 2 is in axial sliding connection with described ring gear 1 and rotates with described ring gear 1；Described magnetic
Yoke includes that inner yoke 6 and outer yoke 9, described outer yoke 9 include disc portion A and cylindrical part A, described inner yoke 6
Including disc portion B and cylindrical part B, described cylindrical part A, described disc portion B and described cylindrical part B are enclosed
Synthesis annular groove, described permanent magnetism body disc 8 is consolidated between described disc portion A and described disc portion B and with both
Connect, in described annular groove, be provided with coil 5；Described armature 3 end face is provided with shoulder hole, being relatively large in diameter of described shoulder hole
Hole in be provided with stage clip 4, the shoulder end face of described shoulder hole is connected with the end thereof contacts of described stage clip 4；Described stage clip 4
Inside be cased with lead, described lead one end through described shoulder hole with described to be connected dish 2 affixed, described lead another
