Problems solved by technology

[0006]The above two common assembly methods have their own advantages and disadvantages, but they are all aimed at the stator-rotor assembly device of the motor, and are not suitable for turbine power generation devices, turbine power generation devices Different from the structure of the general permanent magnet synchronous motor, the product itself has a turbine drive end component. The drive end of the rotor shaft and the drive components such as the turbine are installed in the turbine housing before assembly to form a semi-finished component of the rotor and turbine.

Abstract

The invention discloses a horizontal stator and rotor assembling device and method for turbine power generation equipment, and belongs to the technical field of turbine power generation equipment assembling. The problem that the assembling technology in the prior art is not suitable for coaxial assembling of the stator and the rotor of the turbine power generation equipment is solved. According to the technical scheme, a casing bent plate support is used for installing a stator and casing combination and fixed to the left end of a platform base, a linear guide rail is installed on the right side of the platform base, and a sliding block is assembled on the linear guide rail; the turbine shell sliding bracket is used for installing a rotor and turbine semi-finished product assembly and fixed to the sliding block, the lead screw nut is fixedly installed on the sliding bracket through the lead screw nut base, the ball screw and the lead screw nut are installed in a threaded fit mode, and the hand wheel is used for rotating the ball screw to drive the sliding bracket to move horizontally along the linear guide rail. According to the tool, it is ensured that stator and rotor assemblies of the turbine power generation device are accurate in positioning, reliable in clamping and convenient to assemble, it is effectively ensured that the stator and the rotor do not make adsorption contact or collide in the assembling process, and the assembling quality and efficiency are effectively improved.

Description

technical field [0001] The invention relates to a stator-rotor assembly device and assembly method, in particular to a stator-rotor horizontal assembly device and assembly method for turbine power generation equipment, belonging to the technical field of turbine power generation equipment assembly. Background technique [0002] The structure of the turbo generator has the same coaxial installation of the stator and rotor as the permanent magnet motor. For small and medium-sized turbo generators, due to the magnetic effect of the permanent magnet of the generator rotor, there is a large gap between the generator rotor and the stator during the overall assembly. Due to the strong magnetic adsorption force, the stator and rotor are easily adsorbed together during the assembly process, resulting in quality problems such as winding insulation and bearing scratches. Once adsorbed together, it is difficult to separate, which will affect the assembly work. If it is forced to separat...
