Hoisting device and method for stator iron core of medium-and-large-sized water jacket cooling permanent magnet motor

Abstract

The invention discloses a hoisting device for a stator core of a medium-and-large-sized water jacket cooling permanent magnet motor, which comprises a hoisting ring, the hoisting ring is divided into a lower hoisting ring and an upper hoisting ring which are symmetrically arranged, and the inner side of the hoisting ring is provided with a clamping structure used for being clamped on the outer side of the end surface of the stator core. A plurality of groups of tensioning screw holes for connecting and supporting are uniformly formed in the opposite positions of the upper and lower end surfaces of the lower hoisting ring and the upper hoisting ring, tensioning screws are detachably mounted in the lower hoisting ring and the upper hoisting ring, and a rotary hoisting ring is detachably arranged on the outer circle of the hoisting ring. By adopting the hoisting device and method for the stator iron core of the medium-and-large-sized water jacket cooling permanent magnet motor, the iron core can be hoisted and turned over, and meanwhile, the potential deformation hazard possibly existing in hoisting and subsequent coil inserting procedures can be effectively prevented.

Description

technical field [0001] The invention relates to a lifting device and method for a stator core of a medium and large water jacket cooled permanent magnet motor used in the field of motor assembly. Background technique [0002] At present, the stator core with outer rib cooling or water jacket cooling structure lacks available lifting points on the body, and the outer hoop is generally used to realize the lifting and turning of the core. This method can realize the lifting and turning over of small and medium-sized stator cores, but for larger stator cores, the outer circular hoop cannot effectively prevent the deformation risk of the stator core due to its own weight during lifting and turning over. Moreover, the hoop is lifted by relying on the spigot at the outer circle of the iron core and the friction force after the hoop is clamped. There are certain safety hazards in the application of the heavy iron core. Contents of the invention [0003] The purpose of the present...

This method can realize the lifting and turning over of small and medium-sized stator cores, but for larger stator cores, the outer circular hoop cannot effectively prevent the deformation risk of the stator core due to its own weight during lifting and turning over. In addition, the outer hoop is lifted by the spigot at the outer circle of the iron core and the friction force after the hoop is clamped. There are certain safety hazards in the application of the heavy weight iron core.
