Further, it is pyramidal structure by arranging rotary sleeve inner wall lower so that it is the conical surface contacts with ground floor ball,
Ensure stability when ground floor ball rolls.
Further, by arranging flexible gasket, it is possible to play and compensate gap and adjust the effect of thrust；Can be according to not
Same load and clearance requirement select the pad of dual extension-compression modulus to be adjusted.
Further, by utilizing trip bolt that rotation compression sheet is fixed on rotating shaft upper end, given rational pretightning force
I.e. can reach the purpose going slick and eliminating gap.
Further, it is hollow-core construction by arranging rotating shaft, it is possible to further alleviate the weight that mechanism is overall, it is achieved light
Quantify.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
See Fig. 1-Fig. 4, the revolving support mechanism that the present invention provides, including: the rotating shaft 3 of rotary sleeve 4 it is nested with in outside,
Described rotating shaft 3 top is fixed with rotation and compresses sheet 5；The outer wall of described rotating shaft 3 is circumferentially arranged to be had for carrying ground floor ball 2
Platform 7, platform 7 is provided with the ramp structure 9 for spacing ground floor ball 2, ramp structure 9 can prevent ball landing.
Described rotary sleeve 4 inner wall lower is provided with the pyramidal structure for contacting with ground floor ball 2, this conical surface and platform 7, rotating shaft
The outer wall of 3 realizes and the contacting of ground floor ball 2, and utilizes three planes by spacing for ground floor ball and realize rotary sleeve 4 end
The rolling support in portion.
Described rotary sleeve 4 inwall upper end is provided with the conical surface being easily carried second layer ball 8, this conical surface and rotating shaft 3 outer wall
Form trench structure, it is possible to carrying second layer ball 8；Described rotation compresses on the lower surface of sheet 5, rotating shaft 3 outer wall and rotary sleeve 4
End cone face all contacts with second layer ball 8, utilizes three planes carry out spacing to second layer ball 8 and form rolling support.
It is provided with flexible gasket 1 between compression sheet 5 and the upper surface of rotating shaft 3 described rotation.Rotate and compress sheet 5 by tight
