Abstract
The utility model relates to a rotor magnetic yoke of a single bearing generator. The rotor magnetic yoke of a single bearing generator is composed of a cast flange disk and a forged steel cylinder which are welded. Proved by classical mechanics intensity and finite element analysis, the main bearing position is the part of a magnetic yoke cylinder, therefore the part of the magnetic yoke cylinder uses the high-quality forged steel cylinder; the flange dish is a cast steel piece and has the advantages of simple structure, small technology difficulty and easy guarantee of the quality of casting. The rotor magnetic yoke of a single bearing generator synthesizes the structure advantages of the existing rotor magnetic yokes and can not only meet the requirement of complex construction of the magnetic yoke but also can select proper coefficient of safety and decrease greatly the weight of the magnetic yoke of the weight of the entire generator; besides, the utility model has reasonable cost performance.
Description
Technical field
The utility model relates to single shaft and holds generator, and particularly single shaft holds the structure of generator amature yoke, is specially a kind of single shaft and holds the generator amature yoke.
Background technology
Single shaft holds in the generator, and rotor yoke not only is the part of motor magnetic circuit, also is the main load parts of rotor simultaneously, and its reliability directly affects the global reliability energy of motor.Single shaft holds generator for simplifying the draw bail with actuator (as diesel engine), and an end of rotor yoke has ring flange usually, by ring flange make rotor that single shaft holds generator directly and diesel engine link.
Single shaft holds the generator amature yoke at present following two kinds of structures: 1, cast steel yoke structure (as shown in Figure 1).Its monoblock cast forms, and overall structure can realize the complicated magnetic yoke structure with flange disc, and casting cost is low; But technology difficulty is big, and casting flaws such as gaza, pore are difficult to avoid; For guaranteeing the security reliability of rotor yoke, the mechanical strength coefficient of safety must obtain very big, causes rotor yoke weight and generator complete machine weight to increase.2, forged steel cylinder magnetic yoke structure (as shown in Figure 2).Its technology difficulty is little, can avoid defectives such as gaza, pore, gets suitable mechanical strength coefficient of safety, just can guarantee the security reliability of rotor yoke, and yoke weight and generator complete machine weight reduce significantly; But be subjected to the restriction of processing technology, overall structure can't realize the complicated magnetic yoke structure with flange disc, needs other parts of configuration to realize and being connected and fixed of diesel engine on the generator amature, has a strong impact on applying of such magnetic yoke structure.
Summary of the invention
The utility model solves existing single shaft and holds the problem that the generator amature yoke exists, and the structural advantage of comprehensive above-mentioned existing two kinds of rotor yokes provides a kind of novel single shaft to hold the generator amature yoke.
The utility model is to adopt following technical scheme to realize: single shaft holds the generator amature yoke, is welded by casting flange disc and forged steel cylinder.
Classical mechanics intensity and finite element analysis checking, the main bearing position of rotor yoke is yoke cylinder place, therefore adopts high-quality forged steel cylinder at this place; And flange disc partly is a steel-casting, and is simple in structure, and technology difficulty is less, and casting quality is easy to guarantee.Single shaft described in the utility model holds the structural advantage that the generator amature yoke combines existing rotor yoke, can satisfy the requirement of labyrinth yoke, can choose suitable coefficient of safety again, reduce yoke weight and generator complete machine weight significantly, cost performance is reasonable, has popularizing application prospect widely.
