Abstract
The utility model discloses a staple bolt formula collecting ring fixing base, it includes central body and four earrings, and four earrings are impartial to be installed on the excircle of central body, and the earring is equipped with the screw, and the collecting ring passes through the bolt fastening on the earring. The utility model has the advantages that: the upper end collecting ring and the lower end collecting ring are tightly attached to the four ear rings during installation, most of weight of the upper end collecting ring is supported by the ear rings, only the weight of the lower end collecting ring is firmly pulled by the screw, stress points of the two rings are close to the ear rings, and stability is good.
Description
Technical Field
The utility model relates to a collecting ring fixing base specifically is staple bolt formula collecting ring fixing base.
Background
The collector ring fixing seat of the conventional hydro-generator generally adopts a sleeve type structure to hang the collector ring upside down on a main shaft of the generator, as shown in the following figure I. Because the fixed seat 1 mostly adopts an iron casting, the conventional sleeve type collector ring is influenced by various factors in the manufacturing process, the defects of air holes, pin holes, slag inclusions, cracks, pits and the like can often appear, a special die is needed in the manufacturing process, the universality among different units is poor, and the production cost is high. In addition, the iron casting and other carbon steel parts can not be welded, the requirements on the accuracy of the related parts in the production and installation processes are high, and the iron casting and the other carbon steel parts can only be integrally replaced after being damaged.
The longer generally more than 180mm of this structure fixing base axial length, required generator main shaft cooperation shelves are also corresponding longer during the installation, and 3 weight of two collecting rings are whole to be hung upside down on the flange of fixing base through fixing bolt 2, have certain requirement to fixing base flange and fixing bolt intensity and rigidity, and the structural stability of just hanging upside down is relatively poor. In addition, the flange of the fixed seat is of a full-circle structure, so that the adjusting space of the carbon brush during installation and maintenance is limited.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a staple bolt formula collecting ring fixing base.
In order to achieve the above object, the utility model provides a following technical scheme:
staple bolt formula collecting ring fixing base, it includes central body and four earrings, and four earrings are equallyd divide and install on the excircle of central body, and the earring is equipped with the screw, and the collecting ring passes through the bolt fastening on the earring.
The center of the screw hole is parallel to the central axis of the central body, if the screw hole is not parallel to the central axis, the upper electric brush is likely to spark,
when the unit operates, the whole collecting ring assembly rotates at a high speed along with the rotating shaft, and the electric brush and the conducting ring for fixing the electric brush are relatively static.
The utility model has the advantages that: the upper end collecting ring and the lower end collecting ring are tightly attached to the four ear rings during installation, most of weight of the upper end collecting ring is supported by the ear rings, only the weight of the lower end collecting ring is firmly pulled by the screw, stress points of the two rings are close to the ear rings, and stability is good.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 3-4, the present invention provides a hoop-type collecting ring, wherein the fixing base of the hoop-type collecting ring adopts a hoop-type structure, the hoop-type fixing base adopts a Q235 steel plate welding component, the fixing base is formed by welding a central body and four earrings, the material drawing and the manufacturing of the steel plate welding component are simple, a special mold is not required, the structure is simplified, and the manufacturing cost is reduced. In addition, the welding part is strong in welding performance with other carbon steel parts, and when the welding part is not matched with relevant parts in the production and installation processes, the repairability is strong, and the integral replacement is not needed.
The earrings are provided with platforms for mounting the collecting rings, so that the collecting rings and the earrings can be conveniently mounted.
The axial length of the structure is short and is only about 70mm, a matching gear of a main shaft of a generator required during installation is correspondingly shortened, four ear rings are tightly attached to the upper end collecting ring and the lower end collecting ring during installation, most of the weight of the upper end collecting ring is supported by the ear rings, only the weight of the lower end collecting ring is firmly pulled by a screw, stress points of the two rings are close to the ear rings, and the stability is good. In addition, the hollowed-out design is adopted among the four ear rings of the hoop type collecting ring fixing seat, the operation space is expanded during installation and maintenance, and the carbon brush is convenient to install and adjust.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
