Abstract
The utility model discloses a rotating structure of an isolating switch, which comprises a bearing seat, a bearing and a shaft. The bearing is sleeved inside the bearing seat, the shaft is sleeved inside the bearing, the bearing seat is mounted on a porcelain insulator, the bearing seat is a sealing member, and a group of combined bearing structures are mounted inside the bearing seat, wherein, the combined bearings are thrust bearings and radial bearings. The structure adopts the combination of the thrust bearings and the radial bearings, and gravity and bending moment are born by the two types of special bearings, so that no deformation appears.
Description
Technical field
The utility model relates to a kind of rotational structure of isolating switch, is specifically related to a kind ofly have better stability, solves each rotary part jam problem and can exert all one's strength and disperse the rotational structure of the isolating switch that bears.
Background technology
Because this rotational structure is used for the GW4 Series Switch-disconnector, therefore, is described as follows in conjunction with isolating switch:
GW4 series is in the market kept apart and have following problem on drive mechanism:
A single-row circular cone ball bearing is respectively arranged up and down in the isolating switch bearing pedestal, and this structure need apply certain pretightning force to bearing, otherwise porcelain vase can double swerve.When disconnecting link is in a position for a long time, some balls that can make bearing with joint efforts of the gravity of porcelain vase and last current-carrying part moment of flexure are stressed for a long time, to such an extent as to generation micro-deformation, this moment two bearings held by the effect of pretightning force tighter, when needs rotate, there is bigger power to overcome the distortion of bearing.Add the influence of the temperature difference, rotating shaft elongation in summer, flexible relatively during disconnecting switch operation, the rotating shaft in winter is shunk, and makes the gap littler, tighter.Initial analysis thinks that Here it is, and the operation room interval is long more, needs the big more main cause of operating physical force.Also have a factor, can't make-up oil in long-time running, so corrosion phenomena can take place in the withered rear bearing of lubricating oil, makes operation heavy, the severe patient operation is motionless.
The utility model content
Main task of the present utility model is to provide a kind of rotational structure of isolating switch, constitute by bearing pedestal, bearing, axle, described bearing holder (housing, cover) is in bearing pedestal, axle sleeve is in bearing, described porcelain vase installation shaft is seated against, it is characterized in that: described bearing pedestal is a seal, and one group of combined bearing structure is housed in bearing pedestal.
Described combination bearing is the combination of thrust bearing and radial bearing; Described thrust bearing is contained in the import department of bearing pedestal, and radial bearing is contained in the bottom of thrust bearing.
Described thrust bearing is a plane bearing.
Described radial bearing is a ball bearing.
The advantage of above structure is: adopt thrust to add entad combined bearing structure, gravity and bending moment are born by two kinds of special bearings respectively, can not produce distortion.The two pairs of ball bearings can the dead axle hearts, do not need to carry out abundant pretension, and bearing and Internal and external cycle are and contact, and are difficult for stuck.And bearing pedestal adopts complete design of Sealing Structure, and moisture, dust can not enter in the bearing pedestal, are full of lubricating grease in the bearing, and bearing is operated in the good lubricated environment forever, do not need to safeguard in guaranteeing between total life cycle and lubricated.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
As shown in the figure, bearing pedestal 1 is made into seal, one group of combination bearing is respectively established at two ends up and down in bearing pedestal 1, and described combination bearing is made up of thrust bearing 2 and radial bearing 3, and described thrust bearing 2 is specially plane bearing, and radial bearing 3 is a ball bearing.During concrete the installation, thrust bearing 2 is contained in the outside of radial bearing 3.Axle 4 is inserted in the endoporus of bearing 2,3, and porcelain vase 5 is installed on the bearing pedestal 1.
During use, thrust bearing is born porcelain vase 5 gravity, and ball bearing is born the power that bending moment produces.Like this, the axle center that two radial bearings 3 can dead axles 4, porcelain vase 5 can not produce and rock, and forms point between steel balls and the Internal and external cycle in thrust bearing 2 and the radial bearing 3 and contact, is difficult for the stuck distortion of generation.And because bearing pedestal adopts complete design of Sealing Structure, and moisture, dust can not enter in the bearing pedestal, can repack with grease in the bearing, bearing is operated in the good lubricated environment forever, do not need to safeguard in guaranteeing between total life cycle and lubricated.
Claims (4)
