Abstract

The invention discloses an annular forge piece magnetic yoke structure of a power generation motor. The annular forge piece magnetic yoke structure is composed of a first-section magnetic yoke, a middle-section magnetic yoke, a last-section magnetic yoke, an upper air guide plate, a lower air guide plate, a brake ring, a magnetic yoke tensioning screw rod and nuts, wherein each section of the magnetic yoke section is formed by forging forged pieces, and the thicknesses of the magnetic yoke sections are consistent, so that the magnetic yoke sections do not have the problems of a staggered tooth, stacking gaps and the like; the upper air guide plate and the lower air guide plate are welded in polygonal grooves of the magnetic yoke sections, and each layer of air guide plates is limited by aspigot; the magnetic yoke tensioning screw penetrates into the first-section magnetic yoke, the middle-section magnet yoke, the last-section magnet yoke and the brake ring from top to bottom in sequence, wherein the two surfaces of the magnet yoke tensioning screw are fixed through the nuts, so that an integral magnetic yoke is formed; and a connecting bolt, a pin and a bolt locking part are not arranged in each section of the magnetic yoke section, so that the potential safety hazard of a rotating part connecting piece is reduced, the installation is simple, and the safety and reliability aregreatly improved.

Description

technical field [0001] The invention relates to the field of generator motors, in particular to a ring forging magnetic yoke structure of generator motors. Background technique [0002] With the continuous improvement of the technical level of domestic generator motors, most of the yokes of generator motors with large capacity and high speed adopt the structure of lamination of annular thick steel plates. Each section of the yoke is laminated with multiple round thick steel plates and connected by bolts. As a whole, compared with the traditional laminated yoke, the overall rigidity of the yoke is improved, and the integrity and stability of the generator motor are improved. However, the steel plate stacked yoke has disadvantages such as complex manufacturing process, low material utilization rate, long manufacturing cycle, and gaps between the steel plates of each yoke segment. In order to solve the above problems and further improve the quality of the rigid yoke, the prese...
