Description

Technical Field

[0001] This utility model relates to the field of wind turbine shaft system assembly verification technology, and in particular to a wind turbine shaft system assembly verification tooling. Background Technology

[0002] As an important component of clean energy, wind power generation is developing rapidly towards large-scale and high-efficiency, which has led to a sharp increase in the size and weight of its core transmission chain components, especially the main shaft, bearing housing and gearbox. This has brought unprecedented challenges to the precision assembly and verification of the shaft system in the final assembly stage. Traditional key processes such as alignment, meshing inspection, bearing press-fitting and clearance measurement are facing huge challenges in terms of operational difficulty, precision control and safety risks. In the traditional assembly process of small and medium-sized units, forklifts and other general handling equipment are often used to drive and adjust the posture of the spindle or bearing housing. This method has many limitations. The operation process is cumbersome and discontinuous, relying on the operator's experience and repeated jogging, observation and adjustment, which is inefficient and makes it difficult to guarantee positioning accuracy. The movement driven by the forklift is intermittent and cannot achieve low-speed, smooth and precise angular displacement control. However, this is precisely the condition necessary for checking the meshing spots of planetary gear trains or parallel shaft gears and accurately measuring bearing clearance. Rough operation can easily lead to distorted inspection results, resulting in significant quality hazards and economic risks. It is difficult to truly simulate and verify the relative positional relationship and dynamic matching characteristics of the spindle, bearings and gearbox under stress, making it impossible to effectively discover and eliminate some potential assembly problems during the assembly stage. Therefore, there is an urgent need for an assembly and verification fixture specifically designed for the shaft system of large wind turbines, which provides a low-speed, stable, continuous and precisely controllable rotary drive to simulate real working conditions, achieve precise drive and positioning of the main shaft, and provide a reliable, safe and efficient operating platform for key processes such as high-precision alignment measurement, gear meshing inspection, bearing assembly and clearance adjustment. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind turbine shaft system assembly verification fixture.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A wind turbine shaft assembly verification fixture includes an H-beam base, a slewing bearing, a transmission system, a transition flange, and a shaft bearing seat fixing seat. The slewing bearing is fixedly installed on the H-beam base, and the transition flange is fixedly connected to the inner ring of the slewing bearing. The transmission system is installed on the H-beam base and is connected to the slewing bearing. The shaft bearing seat fixing seat is fixedly installed on the H-beam base.

[0005] As a further embodiment of this utility model: the H-beam base includes a quadrilateral frame formed by welding H-beam profiles, with inner and outer reinforcing ribs inside the frame, and an adjusting washer welded to the middle of the H-beam base.

[0006] As a further improvement of this utility model, the verification fixture also includes an adjustment pad, which is bolted to the bottom of the H-beam base.

[0007] As a further embodiment of this utility model: the outer ring of the slewing support bearing is fixed on the H-beam base, and its inner ring is provided with an internal gear. The transmission system includes a geared motor and a drive gear connected to the output shaft of the geared motor. The drive gear meshes with the internal gear of the inner ring of the slewing support bearing.

[0008] As a further embodiment of this utility model: the transmission system further includes a geared motor base, a gear mounting base, and a gear cover plate. The geared motor base is welded to the H-beam base, and the geared motor and the gear mounting base are fixed to the geared motor base.

[0009] As a further improvement of this utility model, the adapter flange is provided with a positioning pin for positioning with the shaft components to be assembled.

[0010] As a further improvement of this utility model, a nylon gasket is also installed on the adapter flange, and the nylon gasket cooperates with the positioning pin.

[0011] As a further improvement of this utility model: the shaft bearing seat fixing seat is constructed by welding a rectangular tube and a steel plate, and is integrally welded onto the H-beam base.

[0012] Compared with the prior art, this utility model provides a tooling for assembling and verifying the shaft system of a wind turbine, which has the following advantages: 1. The main body of the tooling adopts a quadrilateral frame structure welded from an H-beam base and inner and outer reinforcing ribs, and is equipped with steel components such as shaft bearing seat fixing seats. This ensures that the tooling has extremely high overall rigidity and structural stability when bearing heavy components of the wind turbine shaft system, effectively suppressing deformation and providing a foundation for high-precision assembly verification.

[0013] 2. Adjusting shims and adjusting screws can achieve overall leveling of the tooling. The slewing support bearing allows the measured shaft components to rotate 360 ​​degrees on it, facilitating assembly and measurement at any circumferential position. The locating pins and nylon pads can achieve fast and accurate radial positioning, and the nylon material can protect the workpiece surface from scratches.

[0014] 3. The transmission system, slewing support bearing, shaft bearing seat fixing seat, etc. are all fixed to the base by bolt connection. This not only facilitates the manufacturing, transportation and on-site installation and commissioning of the tooling itself, but also enables it to adapt to the assembly and verification requirements of different models of wind turbine shaft systems by replacing parts.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

The various components are connected by welding or bolts. The adjusting shim 1 is fixed to the bottom of the H-beam base 2 by bolts, and the adjusting shim 1 is a steel structure; The H-beam base 2 includes an H-beam profile, adjusting washer, inner and outer reinforcing ribs and a fixing seat. The H-beam base 2 is welded together by the H-beam profile, inner and outer reinforcing ribs and flange. The adjusting washer is welded to the middle of the H-beam base 2 for leveling the H-beam base 2. The H-beam base 2 is formed into a quadrilateral by welding. The inner and outer reinforcing ribs play a reinforcing role. The shaft bearing seat fixing base 7 is composed of rectangular tube, steel plate, adapter seat and adjustment plate welded together. The shaft bearing seat fixing base 7 is a steel structure, which is welded to the H-beam base 2 through rectangular tube and steel plate. The slewing support bearing 4 is fixed to the fixed seat of the H-beam base 2 by bolts, and its function is to rotate the tooling. The slewing support bearing 4 is a steel structure, with an outer bearing structure and an inner gear. The slewing support bearing 4 is externally connected to the H-beam base 2 by bolts, and the inner ring of the slewing support bearing 4 is fixedly connected to the transition flange 6. The transition flange 6 is a steel structure, and a locating pin and a nylon gasket 5 are installed on the transition flange 6.
