Abstract
The utility model is named a processing device for a collecting ring of a wind driven generator and relates to a device for processing the operation surface of a collecting ring of the wind driven generator. The processing device mainly solves a problem that the conventional collecting ring processing device uses an iron hammer to penetrate an inner cavity of a collecting ring, so that the collecting ring processing device and the inner cavity of the collecting ring are deformed. The processing device provided by the utility model is composed of a false shaft and a flange. The false shaft is an I-shaped structure composed of a shaft body, a shaft shoulder and a shaft head, wherein the shaft shoulder and the shaft head are arranged at two ends of the shaft body and are provided with a guide awl respectively. The end part of the shaft shoulder of the I-shaped false shaft is provided with a disk, and the diameter of the disk is larger than that of the shaft shoulder. Threaded holes are uniformly arranged in the same arc of the disk. The shaft end of the disk is provided with a technical runout step. The shaft head of the I-shaped structure of the false shaft is provided with a threaded hole. According to the structural characteristics of the inner cavity of a collecting ring, the processing device provided by the utility model is in little clearance fit with an inner hole of the collecting ring, utilizes the flange and bolts to assemble the collecting ring, and is convenient to dismount, low in labor intensity and high in efficiency.
Description
Technical field
The utility model relates to collecting ring for wind driven generator processing unit (plant), specifically relates to a kind of device of the processing of the collector ring working surface for wind-driven generator.
Background technology
Collector ring for wind-driven generator, forms collector ring brush holder system jointly with brush holder, and conversion electric current flows to rotor field coil.Cause the reason that such collecting ring for wind driven generator failure rate is high to mainly contain: the shaft voltage of such wind-driven generator self is too high, make bearing damage rate very high, the quantitative change of beating is large, result causes generator in the process of rotating, the quantitative change of beating between the helicla flute on brush and collector ring surface is large, causes inordinate wear, and the earth connection electric current of collector ring increases, between helicla flute and brush, discharge, result causes the electric of collector ring surface to be burnt; Above two kinds of reasons can be brought to collector ring badly damaged, finally cause fault; Traditional collector ring processing unit (plant) is to utilize iron hammer to squeeze into collector ring inner chamber, causes the distortion of collector ring processing unit (plant) and collector ring inner chamber, once collector ring be out of order, the collector ring that major part need to more renew, cost will increase greatly.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and the labour intensity proposing is low, and efficiency is high, and product quality is high, simple in structure, the collecting ring for wind driven generator working surface processing unit (plant) of convenient disassembly during use.
Technical solution of the present utility model is: processing unit (plant) consists of dummy shaft and ring flange, dummy shaft forms an I-shaped structure by the shaft shoulder and the spindle nose that are located at axle body two ends, on the shaft shoulder at I-shaped structure two ends and spindle nose, be respectively equipped with guide cone, in the shaft shoulder end of dummy shaft I-shaped structure, be provided with a disk that is greater than this shaft shoulder diameter, in the same radius arc of disk, be evenly provided with screwed hole, at the axle head of this disk, be provided with the technique amount step of beating, on the spindle nose of dummy shaft I-shaped structure, be provided with screwed hole.
The two ends shaft shoulder and the guide cone tapering on spindle nose of the I-shaped structure described in technical solution of the present utility model are 1:50.
The screwed hole on the spindle nose of dummy shaft I-shaped structure described in technical solution of the present utility model and the screw on ring flange match.
The utility model is according to collector ring inner-cavity structure feature, design collector ring processing unit (plant) and collector ring endoporus form little matched in clearance, be provided with technique jerk value step, the convenient jerk value that detects processing front and back, the jerk value that guarantees the collector ring surface of processing front and back meets the demands, and guarantees to repair precision and quality; Utilize flange and bolt disassembly collector ring, handled easily; The utility model has avoided traditional collector ring processing unit (plant) to utilize iron hammer to squeeze into collector ring inner chamber, causes collector ring processing unit (plant) and the distortion of collector ring inner chamber; Collector ring processing unit (plant) integral body of the present utility model presents I shape, has reduced the contact area of collector ring processing dummy shaft and collector ring inside, has reduced frictional resistance; The utility model collector ring machining device design has guide cone, easily laborsaving while facilitating mandrel to be inserted in collector ring inner chamber, importing, accurate positioning, thus alleviated labour intensity, improved efficiency; The easily manufactured practicality of the utility model, simple in structure, convenient disassembly during use, can not cause the damage of collector ring endoporus, can repeat.
