Description of drawings
Fig. 1 is the profile schematic representation of an embodiment of the present invention
Fig. 2 is that A-A of Fig. 1 is to cross-sectional view.
Embodiment
See figures.1.and.2, a kind of non-contact inversion brake comprises loam cake 2, ball bearing 3, auxiliary inner ring 4, trapezoidal brake slipper 9, main inner ring 10, outer ring 14, lower cover 5, ball 12 and tension spring 13.Described auxiliary inner ring 4 concentric locking collars are contained on the main inner ring 10, tightened together by Internal and external cycle bolt 6 and main inner ring 10, outer ring 14 by ball bearing 3 by auxiliary inner ring 4,10 clampings of main inner ring and with one heart, dynamically link to each other in the outer edge, loam cake 2, lower cover 5 are rotatably connected on the outer edge of auxiliary inner ring 4 and main inner ring 10 by ball bearing 3 clampings, and are fastened on one heart on the outer ring 14 by lid bolt 1; Trapezoidal brake slipper 9 is seated in the cavity between auxiliary inner ring 4, main inner ring 10 and the outer ring 14, and trapezoidal brake slipper 9 inner sides are connected for articulation with main inner ring 10.Main inner ring 10 is provided with the circular ring of inside and outside two-stage step above being, the interior circular hole 11 of this circular ring is provided with the solid keyway 8 of device, and the vertical face of step is provided with recess outside its top, and the outer, bottom is provided with annular groove.Auxiliary inner ring 4 is provided with the circular ring of annular groove for the outer, top.Outer ring 14 is provided with inner convex platform, and locate with auxiliary inner ring 4, main inner ring 10 mutually by ball bearing 3 on these inner convex platform both sides.Described loam cake 2, lower cover 5 are installed in the annular groove of auxiliary inner ring 4, are fixed with outer ring 14 by lid bolt 1.Trapezoidal brake slipper 9 is equipped with tension spring 13 being provided with spring eye 15 with main inner ring 10 contacted interior shoulders in it.One end of described tension spring 13 is packed in the spring eye 15 on the trapezoidal brake slipper 9, and the other end withstands on the sleeping ball 12 that is contained on the main inner ring 10.Auxiliary inner ring 4, main inner ring 10 are fastening by 4 Internal and external cycle bolts 6.Described lower cover 5 is fastened on the outer rim end of outer ring 14 with one heart by 4 lid bolts 1.The circumference of auxiliary inner ring 4, main inner ring 10 is provided with among the solid screw 7(figure of 2-10 devices of mutual perforation and is expressed as 4), be used for connecting the controlled parts of machinery.
Working principle: referring to accompanying drawing 1-Fig. 2, outer ring 14 is (with thick arrow signal) that maintain static, when main inner ring 10 is rotated counterclockwise (the curved arrow signal of dotted line), trapezoidal brake slipper 9 is under the effect of rotatory inertia and centrifugal force, overcome the tension of tension spring 13, clockwise rotate (the curved arrow signal of dotted line) around its " joint ", the outer rim of the trapezoidal brake slipper 9 of this moment breaks away from the inner peripheral surface of outer ring 14, and main inner ring 10 is rotated counterclockwise unimpededly.When main inner ring 10 turns clockwise (the curved arrow signal of solid line), trapezoidal brake slipper 9 is under the effect of rotatory inertia and centrifugal force and tension spring 13 tensions, rotate counterclockwise (the curved arrow signal of solid line) around its " joint ", the trapezoidal brake slipper 9 of this moment is under the effect of tension spring 13, its outer rim is pushed up on 14 inner peripheral surfaces of outer ring, makes 10 brakings of main inner ring and stops to turn clockwise.When main inner ring 10 was rotated counterclockwise again, trapezoidal brake slipper 9 clockwise rotated around its " joint ", and its outer rim breaks away from the inner peripheral surface of outer ring 14, and main inner ring 10 is freed and is rotated counterclockwise unimpededly, so goes round and begins again.
