Abstract
The utility model discloses a pressure bearing for a 330kV live line tool. The pressure bearing comprises a bearing jacket and a protective bowl which is connected with the bearing jacket, wherein a groove is arranged under the bearing jacket, thereby forming an upper inner bearing sleeve; the upper inner bearing sleeve is integrated with the bearing jacket; a groove is arranged in the protective bowl, thereby forming a lower inner bearing sleeve; the lower inner bearing sleeve is integrated with the protective bowl; the protective bowl is provided with an adjusting slot for adjusting the combining tightness of the bearing jacket and the protective bowl; a ball bearing is arranged between the upper inner bearing sleeve and the lower inner bearing sleeve; and adjusting bolts are also arranged on the bearing jacket and the protective bowl. The pressure bearing for the 330kV live line tool has the advantages of reasonable structure, uniform stress, durability, safety, reliability, and capabilities of increasing working efficiency and saving maintenance cost.
Description
Technical field
The utility model relates to the improvement of the pressure bearing of live line working specific purpose tool-suspension string holder (ZK35), and pressure bearing is the critical component of 330kV charged for replacement insulator specific purpose tool suspension string holder.
Background technology
Suspension string holder (ZK35) is mainly used in that charged for replacement is just being gone here and there or the monolithic insulator, and original bearing spider ball spherical radius up and down has only R12mm, the maximum 2mm of Spherical Clearance, and lifting surface area is big, and stress is prone to concentrate; Thrust autumn bearing largest axis skew ± 2mm is prone to produce additional square leading screw and bearing is caused bending failure; Sphere axis peak excursion angle 220 bearing slewing areas are little up and down for bearing pedestal, and have no safeguard procedures.Parts of bearings is prone to lose, weares and teares and gets into dust, influences work, installing/dismounting trouble, length consuming time.Pearl frame cracky in use appears in original pressure bearing the most easily, and steel ball problem such as be prone to be scattered not only influences operating efficiency, returning safety in production and staying hidden danger.
Summary of the invention
The purpose of the utility model is to propose a kind of 330kV tools for live working pressure bearing, can improve, prolong pressure bearing useful life; Increase work efficiency, practice thrift maintenance cost.
The technical scheme of the utility model is to solve like this:
Comprise bearing outside and the protection bowl that is connected with bearing outside; Be provided with groove below the bearing outside and form interior cover on the bearing; Cover is an integral body with bearing outside in going up, be provided with above the protection bowl groove form bearing down in cover, down in cover and protection bowl be an integral body.
The protection bowl also is provided with a regulating tank, combines tightness to regulate overcoat with the protection bowl.
Be provided with ball bearing between the interior up and down cover of bearing.
Bearing outside also is provided with the protection bowl and regulates pin.
The purpose of the utility model is to improve the shortcoming of above-mentioned original bearing, makes it rational in infrastructure, stressed even, durable in use, safe and reliable, increases work efficiency, and practices thrift maintenance cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model bearing outside structural representation;
Fig. 3 is a protection bowl structure sketch map;
Fig. 4 is a bowl holder structure sketch map;
Among the figure: 1, bearing outside; 2, pin (adjusting bolt); 3, ball bearing (frame); 4, bearing (on) in the cover; 5, regulating tank; 6, bowl holder; 7 protection bowls (the interior down cover of bearing).
Below in conjunction with accompanying drawing the content of the utility model is done further explain.
Embodiment
Shown in accompanying drawing; Comprise bearing outside and the protection bowl that is connected with bearing outside, be provided with below the bearing outside groove form on the bearing in cover, cover and bearing outside are an integral body in going up; Be provided with above the protection bowl groove form bearing down in cover, down in cover and protection bowl be an integral body.The protection bowl also is provided with a regulating tank, combines tightness to regulate overcoat with the protection bowl.Be provided with ball bearing between the interior up and down cover of bearing.Bearing outside also is provided with the protection bowl and regulates pin.
During assembling with ball bearing (frame) be placed into bearing in the bearing outside (on) in cover, coat lubricating oil, cover the protection bowl, guarantee during assembling that bearing on the protection bowl is trapped and gone up cover to combine, in regulating tank, insert pin, assembling completion at last.
Assembling completion rear bearing overcoat, ball bearing, protection bowl-type become an integral body, and the adjusting during use just relies on regulates the combination tightness that pin is regulated overcoat and protection bowl.In addition, the wrist holder separates with bearing integral, only plays to prevent that bearing protection bowl from directly contacting with the jig leading screw, causes wearing and tearing.
Improved pressure bearing mainly contains 7 parts to be formed, and the main effect of bearing outside is support and protects bearing that improved bearing mainly comprises four primary elements: ball, interior ring, outer shroud and retainer.Ball is processed with high chrome with ring, and the centre of steel ring and outer rim can also be rotated when bearing bigger load in ball was contained in.Ball bearing pivoting friction resistance is little, under the identical rotating speed, because fricative temperature can be lower.Can also satisfy the flexibility requirement when rotating.Whole bearing is by up and down cover protection in two, and last cover and overcoat are an integral body, and trapping and protecting bowl is an integral body, and protection bowl has also designed a regulating tank, with adjusting upper and lower sleeve combination tightness.The bottom is a bowl holder, and bearing has been played protective effect.
