Compared with prior art, one of them technological scheme of magnetic ball pivot of the present invention has the following advantages:
1, the material selection magnet of spheroid, and with ball seat, by magnetic, be connected, namely, ball seat can be made by the material that magnet holds by iron, cobalt, nickel etc.Spheroid is connected by magnetic with ball seat, has reduced the usage requirement of ball seat, has improved the scope selected of ball seat.
2, the camber of the spherical arc of holding cavity is not more than the radius of spheroid, namely, when the part that holding cavity coats spheroid reaches maximum magnitude, has coated a great circle of spheroid, and with one side of this great circle and the roundlet parallel with great circle place face.Certainly, holding cavity also can not coat any one great circle of spheroid.In spheroid, so-called great circle, refer to the circle that sphere is intercepted by the plane through the centre of sphere.So-called roundlet, refer to the circle that sphere is intercepted by the cross section without the centre of sphere.
3, be provided with the ball seat connecting rod on ball seat, facilitate the ball seat installation and use.According to different user demands, the position that can select the ball seat connecting rod to arrange on ball seat.
4, holding cavity, or/and bulb arranges smooth layer, makes the frictional force between bulb and holding cavity less, and the rotation between bulb and ball seat is more flexible, the longer service life of magnetic ball pivot.Simultaneously, as required, can practical oiling agent reduce the friction between bulb and ball seat.Smooth layer is preferably used bearing alloy material, and bearing metal claims again bearing alloy, is the material for the manufacture of sliding bearing, and prior art is very ripe.
5, the ball handle is set to outer inclined-plane near the holding cavity accent place that the position of spheroid is provided with annular position increasing groove, ball seat, all can increase the rotation angle of bulb.
6, establish a telescopic cover at magnetic ball pivot overcoat, with magnetic ball pivot environmental sealing, the impurity such as placement iron filings enter between spheroid and ball seat.
This novel described magnetic ball pivot, be applicable to that load is light, the Environmental Conditions of high speed rotating.This magnetic ball pivot assembling is very simple, during assembling, only needs that spheroid is put into holding cavity and gets final product.Equally, dismounting also is very easy to.
