Locking disc for wind driven generator

Abstract

A locking disc for a wind driven generator relates to the technical field of wind power generation equipment and is used for locking a shaft sleeve body and a main shaft body, and one end of the main shaft body is coaxially inserted into the shaft sleeve body. The locking disc further comprises an outer ring, an inner ring and a connecting disc. The sleeve body of the shaft sleeve body is sleeved with the inner ring, the outer edge of the inner ring is of a conical structure, and a center hole of the outer ring is a conical hole correspondingly matched with the conical outer edge of the inner ring. An annular connecting disc is installed at the large-head end of the inner ring, a plurality of installing holes are annularly formed in the outer side, corresponding to the inner ring, of the connecting disc at intervals, locking screws correspondingly connected with the outer ring in a fastened mode are installed in the installing holes, and the end face of the large-head end of the inner ring correspondingly abuts against the connecting disc. The locking disc is simple in structure, easy to assemble and low in production cost, compared with a traditional locking disc structure, the inner ring can be directly formed and machined through a round pipe, the machining efficiency is greatly improved, meanwhile, the material utilization rate is increased, and the machining cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a shrink disc for a wind power generator. Background technique [0002] As we all know, wind energy, as a kind of abundant, green and renewable energy, has been paid more and more attention by people, and wind power generation equipment has risen rapidly. For wind power shrink disks, the shrink disk is mainly composed of inner ring, outer ring and bolts. The inner hole of the outer ring of the traditional shrink disk has steps and inner conical surfaces, and threaded holes are uniformly distributed on the steps; the outer circle of the inner ring has legal The flange and the outer conical surface, the flange is made with screw through holes equal in number to the threaded holes on the outer ring step; the flange of the inner ring and the outer conical surface are assembled with the steps of the outer ring and the inner conical surface Together, the locking disc is ...

Problems solved by technology

[0002] As we all know, wind energy, as a kind of abundant, green and renewable energy, has been paid more and more attention by people, and wind power generation equipment has risen rapidly. For wind power shrink disks, the shrink disk is mainly composed of inner ring, outer ring and bolts. The inner hole of the outer ring of the traditional shrink disk has steps and an inner conical surface, and threaded holes are evenly distributed on the steps; the outer circle of the inner ring has legal The flange and the outer conical surface, the flange is made with the same number of threaded holes corresponding to the threaded holes on the outer ring step; the inner ring flange and outer conical surface are assembled with the steps of the outer ring and the inner conical surface Together, the locking disc is locked by fastening bolts; due to the characteristics of the inner ring structure, the structure of the inner ring is only about 20% of the total blank, the waste of steel is huge, the proportion of processing consumables is high, and the processing time is long ; In addition, the traditional locking disc is limited to structural influences, resulting in complex installation and disassembly processes, time-consuming and labor-intensive, and this phenomenon is an urgent problem to be solved by those skilled in the art;

[0003] The existing patent discloses a snap-fit ​​component device of the inner ring of the wind power locking disc. In this patent, an inner ring flange is provided at the end of the inner ring, and a stop snap-fit ​​is arranged between the inner ring flange and the inner ring. Although the The patented inner ring and the inner ring flange can be processed separately to save steel, but this patent requires the inner ring and the inner ring flange to be connected as one through the inner ring stop card key to be used. The assembly process is complicated and inconvenient to use.
