Abstract

The utility model discloses a bearing seat device of a high-voltage isolating switch, which comprises a main shaft body, a framework oil seal, a bearing I, a bearing seat, a bearing II, an elastic retaining ring for shafts, an elastic retaining ring for holes, and a sealing cover plate. First of all, the bearing II, the bearing I, the elastic retaining ring for holes and the bearing seat are assembled together; then, the framework oil seal is assembled; then, the main shaft body and the elastic retaining ring for shafts are assembled; and finally, the sealing cover plate is assembled. Two ends of the bearing seat are sealed by the framework oil seal and the sealing cover plate respectively so as to prevent water or dust from coming into an inner cavity of the bearing seat, thereby effectively avoiding a problem of clamping stagnation of main shaft body rotation caused by rustiness of the bearings and deterioration of lubricating grease.

Description

A kind of bearing holder device of high voltage isolator

Technical field

The utility model relates to High-Voltage Electrical Appliances, is specially a kind of bearing holder device of high voltage isolator.

Background technology

Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance, is to play buffer action in circuit.Principles and structure itself is fairly simple, but because use amount is large, functional reliability requires high, and is all larger on the impact of design, foundation and the safe operation of electric substation, power plant.High voltage isolator is minute, close no load condition circuit, safety isolation repair apparatus and change-over circuit; And should be able to pass through reliably rated current in running status.High voltage isolator present and that this technology approaches has GW4, GW5 type, and its bearing pedestal part is made of bearing pedestal, turntable shaft, bearing, and its operation principle is: bearing pedestal, turntable shaft, bearing connect together by assembling, and turntable shaft can rotate freely 90 degree.The bearing pedestal part of old structure does not possess water-proof function, the easy corrosion clamping stagnation of bearing.

The utility model content

The technical problem that the utility model solves is to provide a kind of bearing holder device of high voltage isolator, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

A kind of bearing holder device of high voltage isolator, comprise main shaft, outside framework oil seal, bearing one, bearing pedestal, bearing two, circlip for shaft, circlip for hole, seal cover board, described bearing two, described bearing one, described circlip for hole and described bearing pedestal are assembled together first, then load onto described outside framework oil seal, then loading onto described main shaft and described circlip for shaft, load onto at last described oil sealing cover plate, main shaft, the bearing pedestal material employing trade mark are 6063 aluminium, die cast.

Beneficial effect

A kind of high-voltage isolating switch bearing seat of the utility model, this structure are closed designs, and itself just has the dustproof and rainproof function, and main shaft and the bearing pedestal employing trade mark are 6063 aluminium, die cast.Its quality is lighter than cast steel, ironcasting, and the strength ratio aluminum casting is high, and pore-free, good airproof performance, and outward appearance is regular.Bearing pedestal upper end dress deep groove ball bearing, the lower end dress is with the deep groove ball bearing of sealing ring, and main shaft rotates more flexible when making operation.The bearing pedestal two ends seal with outside framework oil seal and seal cover board, make water or dust can't enter the bearing pedestal inner chamber.Effectively avoided bearing rust, the rotten main shaft that causes of lubricating grease to rotate the problem of clamping stagnation.

Description of drawings

Fig. 1 is a kind of high-voltage isolating switch bearing seat schematic diagram.

Among the figure: main shaft 1, outside framework oil seal 2, bearing 1, bearing pedestal 4, bearing 25, circlip for shaft 6, circlip for hole 7, seal cover board 8.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, a kind of high-voltage isolating switch bearing seat of this utility model, comprise main shaft 1, outside framework oil seal 2, bearing 1, bearing pedestal 4, bearing 25, circlip for shaft 6, circlip for hole 7, seal cover board 8, bearing 25 described in this structure, described bearing 1, described circlip for hole 6 are assembled together first with described bearing pedestal 4, then load onto described outside framework oil seal 2, then load onto described main shaft 1 and described circlip for shaft 6, loading onto at last described seal cover board 8.Described main shaft 1 and the described bearing pedestal 4 employing trades mark are 6063 aluminium, die cast.This structure is closed design, and itself just has the dustproof and rainproof function.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. the bearing holder device of a high voltage isolator comprises main shaft, outside framework oil seal, bearing one, bearing pedestal, bearing two, circlip for shaft, circlip for hole, seal cover board, it is characterized in that, described bearing one, described bearing two, described circlip for hole and described bearing pedestal are assembled together first, then load onto described outside framework oil seal, and then load onto described main shaft and described circlip for shaft, load onto at last described seal cover board.
