Abstract
The utility model belongs to the technical field of the bearing frame, concretely relates to isolator major loop insulation bearing frame for lead screw, including outer radial bearing, outer gasket, outer framework rubber oil seal, flange, interior framework rubber oil seal, interior gasket, interior radial ball bearing and O type sealing washer, the utility model discloses utilize a flange, in flange one end stretched into the air chamber, the flange other end was fixed on the air chamber surface, still was equipped with O type sealing washer at its inside framework rubber oil seal that packs into with SF6 gas leakage in preventing the air chamber, the flange one end in the air chamber, and the dress is outside and inside at the air chamber respectively for two radial ball bearing dresses in addition for the rotary motion of transmission lead screw. This mechanism is small, simple structure, leakproofness are good.
Description
Technical field
This utility model belongs to bearing block technical field, is specifically related to a kind of disconnecting switch major loop empire silk thick stick bearing block.
Background technology
The gas-filling cabinet tri-station isolating switch major loop insulation leading screw bearing block of prior art, form is varied, but mostly presents the weak points such as volume relatively big, structure complexity, poor reliability.
For above present situation, main target of the present utility model is: provide the insulation leading screw bearing block that a kind of volume is little, simple and compact for structure, reliability is high.
Summary of the invention
The purpose of this utility model seeks to two radial ball bearings providing a kind of support for transmitting leading screw rotary motion, and its internal structure design sealing is good, is avoided that the insulation leading screw bearing block that the leakage reliability of gas is high.
This utility model is achieved through the following technical solutions:
A kind of disconnecting switch major loop empire silk thick stick bearing block, including outer radial bearing 1, outer pad 2, external frame type rubber oil sea 3, flange 4, internal skeleton posture rubber oil sea 5, internal gasket 6, interior radial ball bearing 7 and O RunddichtringO 8, described flange 4 has one end of protruding 41 and stretches in air chamber, and on flange 4, equally distributed circular lance 42 is for fixing six welding screws that air chamber outer surface is corresponding；Outer radial bearing 1, outer pad 2 and external frame type rubber oil sea 3 are assemblied in one end that flange 4 is away from protruding 41 successively, and internal skeleton posture rubber oil sea 5, internal gasket 6 and interior radial ball bearing 7 are assemblied in projection 41 one end of flange 4 successively.
In order to preferably realize the purpose of this utility model, in external frame type rubber oil sea 3 and internal skeleton posture rubber oil sea 5 cavity, it is full of silicone grease.
In order to preferably realize the purpose of this utility model, O RunddichtringO 8 loads in the seal groove on flange 4 surface.
Compared with prior art, the beneficial effects of the utility model are:
This utility model utilizes a flange, flange one end is stretched in air chamber, the flange other end is fixed on plenum surface, load skeleton rubber oil sea therein to leak with SF6 gas in preventing air chamber, flange one end in air chamber is also equipped with O RunddichtringO, in addition two radial ball bearing dresses are attached separately to air chamber outwardly and inwardly, for transmitting the rotary motion of leading screw.This organization volume is little, simple in construction, sealing are good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: outer radial bearing, outer pad, 3. external frame type rubber oil sea, 4. flange, 41. projections, 42. circular lances, 5. internal skeleton posture rubber oil sea, 6. internal gasket, 7. in radial ball bearing, 8.O RunddichtringO.
Detailed description of the invention
Below this utility model is described further:
A kind of disconnecting switch major loop empire silk thick stick bearing block, including outer radial bearing 1, outer pad 2, external frame type rubber oil sea 3, flange 4, internal skeleton posture rubber oil sea 5, internal gasket 6, interior radial ball bearing 7 and O RunddichtringO 8, described flange 4 has one end of protruding 41 and stretches in air chamber, and on flange 4, equally distributed circular lance 42 is for fixing six welding screws that air chamber outer surface is corresponding；Outer radial bearing 1, outer pad 2 and external frame type rubber oil sea 3 are assemblied in one end that flange 4 is away from protruding 41 successively, and internal skeleton posture rubber oil sea 5, internal gasket 6 and interior radial ball bearing 7 are assemblied in projection 41 one end of flange 4 successively.
In order to preferably realize the purpose of this utility model, in external frame type rubber oil sea 3 and internal skeleton posture rubber oil sea 5 cavity, it is full of silicone grease.
In order to preferably realize the purpose of this utility model, O RunddichtringO 8 loads in the seal groove on flange 4 surface.
This utility model utilizes a flange, flange one end is stretched in air chamber, the flange other end is fixed on plenum surface, load skeleton rubber oil sea therein to leak with SF6 gas in preventing air chamber, flange one end in air chamber is also equipped with O RunddichtringO, in addition two radial ball bearing dresses are attached separately to air chamber outwardly and inwardly, for transmitting the rotary motion of leading screw.This organization volume is little, simple in construction, sealing are good.
