Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment one
Seeing Fig. 1, the support rotary apparatus of the present embodiment includes spring bearing external member 11, support shaft 12.Support shaft bearing sleeve
Part 11 includes spring bearing 111, support sleeve 112 and bearing (ball) cover 113, leakage device of setting up defences in bearing (ball) cover 113；Support shaft 12
Along Z axis from bottom to top through spring bearing 111 and bearing (ball) cover 113；Support shaft 12 includes successively decreasing along Z axis diameter from bottom to top
First multidiameter the 121, second multidiameter 122 and thread segment 123.
Seeing Fig. 2, support shaft 12 has the passage 124 along the through bottom surface of axis and end face；There is lower company support sleeve 112 lower end
Adapter mouth 1121, the adjacent lower connection mouth of pipe 1121 has first shoulder hole the 1122, second shoulder hole of increasing diameter in Z-axis direction
1123 and the 3rd shoulder hole 1124, bearing (ball) cover 113 includes door 1131 and union (screwed)bonnet (UB 1132, the union (screwed)bonnet (UB that diameter successively decreases
1132 threaded with the 3rd shoulder hole 1124, and leak-proof device includes the sealed groove 1133 being located at bearing (ball) cover 113 centre bore
And it is enclosed within the first sealing ring 1134 of the second multidiameter 1123 relevant position, sealed groove 1133 and the first sealing ring 1134 phase
Adaptation, also includes the second sealing ring 1135 being enclosed within union (screwed)bonnet (UB 1132, and the second sealing ring 1135 offsets with door 1131.The
The end face of one multidiameter 121 has the drain tank 1211 of through radial direction.The diameter of the lower connection mouth of pipe 1121 is less than the first ladder
The diameter in hole 1122, also includes the 3rd sealing ring 1136, the external diameter of the 3rd sealing ring 1136 and the lower diameter being connected the mouth of pipe 1121
Suitable.
Seeing Fig. 3, spring bearing 111 is annular bearing with rolling contact, in the inner ring of spring bearing 111 and bearing (ball) cover 113
Central hole all with the second multidiameter 122 matched in clearance；The diameter of the first multidiameter 121 is more than spring bearing 111 diameter of bore.First
Multidiameter 121 coordinates with the diametric clearance of the second shoulder hole 1123, the external diameter of spring bearing 111 and the 3rd shoulder hole 1124 gap
Coordinating, the length of the first multidiameter 121 is less than the degree of depth of the second shoulder hole 1123, and the length of the second multidiameter 122 is more than supporting
The bottom surface of bearing 111 and the distance of bearing (ball) cover 113 end face, the diameter of the first shoulder hole 1122 is more than the diameter of passage 124.The
The difference of the length of the degree of depth of two shoulder holes 1123 and the first multidiameter 121, more than length and the support shaft of the second multidiameter 122
Hold the difference of 111 bottoms and the distance on bearing (ball) cover 113 top, also include stop nut 126, stop nut 126 and thread segment
123 match, and prevent liquid material from causing support shaft 12 to move down the impact to support sleeve 112 when giving up the throne.
See Fig. 4, owing to the centre bore of the inner ring of spring bearing 111 and bearing (ball) cover 113 is all and between the second multidiameter 122
Gap coordinates, and the first multidiameter 121 coordinates with the diametric clearance of the second shoulder hole 1123, is fixed in being supported by of thread segment 123
The most when rotated, support shaft 12 is rotated smooth and easy external rotary part 18 by rotary part, when liquid material is from lower connecting tube
When mouth 1121 is delivered up, liquid material enters the passage 124 of support shaft through the first shoulder hole 1122 and enters external rotation
Rotation member, simultaneously as the diameter of the first shoulder hole 1122 is more than the diameter of passage 124 so that liquid material is to support shaft 12
Bottom surface produce thrust, owing to the length of the first multidiameter 121 is less than the degree of depth of the second shoulder hole 1123 so that the first multidiameter
121 can move up in the second shoulder hole 1123 so that liquid material from the bottom surface of support shaft 12 to the outside of support shaft 12
Wall permeates, and is upwards full of the 3rd shoulder hole 1124, is filled in the liquid material in the 3rd shoulder hole 1124 gap to support shaft
The mobile generation damping action of 12, has dissolved support shaft 12 and has moved up the impact to support sleeve 112, made running steady.Let out
Tank 1211 improves the speed that liquid material permeates to the lateral wall of support shaft 12 from the bottom surface of support shaft 12, makes running more flat
Surely.
Embodiment two
The present embodiment is essentially identical with embodiment one, and its difference is, sees Fig. 5, and spring bearing 111 is thrust bearing.
