Abstract
Disclosed is an outdoor high voltage isolating switch bearing base, which is used to solve the problem of sealing reliability of the outdoor high pressure isolating switch bearing base. The outdoor high pressure isolating switch bearing base is composed of a bearing base, a spline shaft, a rotational flange, an upper bearing, a lower bearing, a locking screw nut, a spline sleeve, an upper sealing cover, a lower sealing cover, an upper sealing ring and a lower sealing ring. The upper bearing, the lower bearing and the spline shaft are placed on the bearing base, the upper bearing, the lower bearing and the spline shaft are locked by the locking screw nut, the spline sleeve supports the rotational flange to drive, the rotational flange is connected with the spline shaft via spline, the rotational flange is externally connected with a rain-proof cover, the lower sealing cover at the lower end of the bearing base brings convenience for dismounting the upper bearing and the lower bearing, and is sealed without gaps, the bearing base and the rotational flange are sealed via the upper sealing ring, because a concave structure of a sealing groove has labyrinth characteristic, the position of the upper sealing cover at the upper end of the spline shaft and a cavity are sealed by seal gum, thereby achieving the zero clearance sealing effect.
Description
Technical field:
The utility model relates to the High-Voltage Electrical Appliances rotatable parts, is specially a kind of improvement outdoor high-voltage isolating switch bearing pedestal.
Background technology:
In the high voltage power transmission and transforming, outdoor disconnector uses in electrical network in a large number as the twin columns type or the three column type outdoor high-voltage isolating switchs of a kind of high-voltage electrical equipment of a large amount of uses, particularly central breakaway-element.Bearing pedestal is as the support and the rotatable parts of porcelain vase, and the flexibility of motion will directly influence the divide-shut brake action of isolating switch.Bearing pedestal since long term exposure out of doors, as poor sealing, rainwater, aqueous vapor, dust etc. enter bearing, to cause bearing corrosion or clamping stagnation, influence the operational motion of isolating switch, to cause the isolating switch can not divide-shut brake during serious clamping stagnation, cause damage, electric power system will be caused serious accident part.In the prior art, the no sealing ring that has only has rain cover, and aqueous vapor and dust very easily immerse; Or add backbone sealing ring at upper end bearing place, but backbone sealing ring need have certain magnitude of interference with cooperating of rotating shaft, and coefficient of friction is big, rotates very flexible, can increase operating physical force.
The utility model content:
The purpose of this utility model is to propose a kind of improvement outdoor high-voltage isolating switch bearing pedestal, is used to solve rainproof, the anti-aqueous vapor and the dustproof problem of prior art bottom bracket, can make the outdoor disconnector long-time running and flexible operation.
The purpose of this utility model is to realize by following technical scheme:
A kind of outdoor high-voltage isolating switch bearing pedestal, by rain cover, bearing pedestal, splined shaft, rotate flange, metal (upper, locking nut, spline housing, upper-lower seal lid and upper-lower seal circle constitute, place, top cover labyrinth shape chamber filling with sealant, it is characterized in that: on, lower bearing and splined shaft place in the bearing pedestal, splined shaft and metal (upper constitute revolute pair, rotating flange is connected by spline with splined shaft, the rotation flange is positioned at the upper end of bearing pedestal, the lower end of bearing pedestal seals by lower sealing cover, the upper end is rotated flange and is connected with a rain cover outward by last sealing ring and top cover labyrinth sealing.
Described lower bearing and upper bearing (metal) are locked by locking nut.
The lower sealing cover of described bearing pedestal lower end is gap-free sealed.
Description of drawings:
Fig. 1 is the utility model structural representation.
The sequence number of each member is among the figure: 1. lower seal; 2. lower bearing; 3. bearing pedestal; 4. upper bearing (metal); 5. go up sealing ring; 6. spline housing; 7. top cover labyrinth; 8. locking nut; 9. rotation flange; 10. splined shaft; 11. lower sealing cover.
Embodiment:
Referring to Fig. 1, specifically constitute: metal (upper and splined shaft place in the bearing pedestal, by locking nut locking metal (upper and splined shaft, by spline housing the support of rotating flange are formed transmission, the bearing pedestal lower end is provided with lower sealing cover, convenient dismounting to metal (upper; Rotating flange is connected with splined shaft by spline, the lower sealing cover of bearing pedestal lower end is gap-free sealed, the sealing of bearing pedestal and rotation flange is by last sealing ring sealing, because the concave structure of seal groove, has the labyrinth type characteristic, the top cover labyrinth of splined shaft upper end and the filling with sealant sealing of place, shape chamber can reach gap-free sealed effect; Rotate flange and be connected with a rain cover outward.
The utility model bearing pedestal and rotation flange adopt aluminium alloy castings, and bearing pedestal and method of rotation your beautiful writings gap are little and be provided with sealing ring, can effectively seal, and sealing ring adopts wear-resisting and has lubricated material and makes, and resistance to wear is good and coefficient of friction is low; Rotate flange and be connected by spline with splined shaft, convenient disassembly, the bearing pedestal lower end is provided with lower sealing cover, can be conveniently to the dismounting of metal (upper.
