Rotor, motor, reinforcing ring tooling and mounting method thereof

Abstract

The invention provides a rotor, a motor, a reinforcing ring tooling and a mounting method thereof. The reinforcing ring tooling can be mounted at the periphery of the rotor of the motor, the reinforcing ring tooling comprises more than two split components and more than two connecting parts, wherein more than two connecting parts are corresponding to more than two split components, and more than two split components are mutually connected through more than two connecting parts to form an annular body; at least two connecting parts in more than two connecting parts are movable connection parts,and the corresponding split components are mutually and movably connected through the movable connection parts, thereby enabling the reinforcing ring tooling to detachably connect with the peripheryof the rotor. Therefore, one or more aims of preventing the rotor from deforming in the transportation mounting process of the motor, reducing the manufacturing cost of the motor, reducing the transportation and mounting of the motor and like operation difficulties can be realized.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotor, a motor, a reinforcing ring tooling and an installation method thereof. Background technique [0002] At present, because the low-speed large-diameter motor has many advantages, it has been widely used. For example, in the field of wind power generation, direct-drive wind turbines are widely used because they have many advantages such as high efficiency at low wind speeds, low noise, long life, and low operation and maintenance costs. However, as the power of the wind power generator increases, the volume and weight of the motor in the direct drive wind power generator also increases. [0003] For example, for a permanent magnet synchronous motor, it is mainly composed of a stator and a rotor. For an outer rotor motor, the stator is fixed at the center of the motor, and the rotor is sleeved on the outer periphery of the stator so that the rotor can rotate around the central axis o...

AI Technical Summary

Problems solved by technology

However, since the rotor yoke is a thin-walled part with a large diameter, the rotor is easily deformed during the machining, transportation, and installation of the motor.

[0004] In order to solve the problem of deformation of the rotor during machining, transportation and installation, one way in the current prior art is to weld a permanent reinforcement ring on the outer wall of the rotor yoke, which not only increases the overall size of the motor, but also increases the The material cost of the motor

Another way is to use a temporary reinforcement ring welded on the outer wall of the rotor yoke, although this will not increase the material cost of the motor, but the rotor needs to be cut, polished, anti-corrosion and other operations, so the processing cost is higher
