Description

Technical Field

[0001] The invention belongs to the technical field of bearing tests, and in particular relates to a wind turbine main shaft bearing working condition simulation test device. Background Art

[0002] Wind is one of the pollution-free energy sources. Moreover, it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that are short of water, fuel and have inconvenient transportation, it is very suitable and promising to use wind power to generate electricity according to local conditions. Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Using wind power to generate electricity is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries around the world.

[0003] The wind turbine main shaft bearing is a key component of wind power generation. The probability of damage and failure of other parts of wind power generation is not high. Although the wind turbine main shaft bearing itself is not very valuable, it is installed in mid-air. After the main shaft bearing is damaged, the cost of replacement is too high; plains, mountains, and oceans.

[0004] The main bearing is indispensable in the process of wind power generation, so it is necessary to test the main bearing during processing. The staff is required to fix the bearing in the test unit and rotate it at high speed, and simulate fluid convection. The wind power fins are subjected to axial force and radial force, and there will be overturning moment when the bearing is working. If it is not tested, it will affect the test accuracy of the bearing. At the same time, the existing test equipment is relatively bulky, which makes it difficult for manpower to quickly install and disassemble the bearing to be tested, and the center of the bearing needs to be repeatedly adjusted during installation, which makes the equipment not only time-consuming and labor-intensive when testing the bearing, but also affects the accuracy of bearing detection.

At the same time, the cross-section of the limiting slide groove 28 is a T-shaped structure, which can ensure the stability of the adjustment of the loading seat 27. Due to fluid convection, the fins of wind power are subjected to axial force, radial force and overturning moment, and the wind power equipment in the mountains is affected by the upper and lower wind directions, which produces a greater overturning moment. Then, the equipment components can adjust the position of the loading seat 27 as needed, and then can select a suitable overturning moment according to the different sizes of the test bearing 17.

The plunger pump is placed inside the oil tank and driven by a servo motor to provide power hydraulic oil for the hydraulic cylinder. Its oil outlet is connected to the cylinder through a valve group integrated block; the main oil circuit adopts a superimposed control mode of the relief valve and the digital servo valve, the relief valve controls the pressure, and the throttle valve controls the opening size; the electromagnetic reversing valve plays the role of oil reversing, and is mainly used to control the loading, unloading or reverse action of the hydraulic cylinder; the pressure gauge and the oil pressure sensor are used to monitor the system oil pressure and the oil pressure in the working chamber of the cylinder respectively. During the loading process of the hydraulic system, the lower controller controls the speed of the servo motor to achieve the effect of force addition / reduction and force maintenance. Since the servo motor has precise control capabilities, and the servo motor and pump dynamically supplement the pressure of the main oil circuit in real time, there is no need to operate at full power. Therefore, the hydraulic loading system has the advantages of high loading accuracy, low working noise, low maintenance cost, energy saving and environmental protection.

[0051] Among them Figure 3 As shown, the reinforcement mechanism includes a reinforcement groove 33, a reinforcement rod body 3301 and a reinforcement ring 3302.

The reinforcement rod body 3301 is threadedly connected to the inside of the reinforcement groove 33, and the reinforcement ring 3302 is knotted on the outside of the reinforcement rod body 3301. The reinforcement groove 33 is located on the upper end surface of the flat plate base 1, and the position of the reinforcement rod body 3301 can be adjusted by rotating the reinforcement ring 3302, so that the reinforcement rod body 3301 can be in contact with the lower end of the test unit component 14, thereby being able to limit the position of the test unit component 14.

[0052] Working principle: First of all, it should be noted that the disassembly component can select the appropriate tapered bearing 18 to transition according to the different sizes of the test bearing 17 to be tested, and the test bearing 17 to be tested can be locked and limited without repeatedly adjusting the center point. Since the tapered bearing 18 will not break, it can also prevent oil leakage. At the same time, the overturning moment loading mechanism is set in two groups, which can maximize the stability of the test unit components during operation and avoid shaking of the test unit components to affect the subsequent processing of the equipment;

[0053] Then place the flat plate base 1 at the specified position, and clamp the supporting main shaft frame 2 on the inner side of the connecting groove 101, and the connecting groove 101 provided can limit the position of the supporting main shaft frame 2, and install the main shaft assembly body 5 in the limiting groove 4 inside the supporting main shaft frame 2, and then, the supporting main shaft frame 2 and the supporting secondary shaft frame 3 can be connected by passing the connecting screw hole 301 on the outer side of the supporting secondary shaft frame 3 through the bolt, and the provided locking clamp ring 7 can be threadedly connected to one side of the supporting main shaft frame 2 and the supporting secondary shaft frame 3, thereby ensuring the tightness of the connection between the supporting main shaft frame 2 and the supporting secondary shaft frame 3, and then, the provided loading kit 12 can lock and limit the position of the spacer body 11 and the locking collar 13, so as to ensure the working stability when the main shaft assembly body 5 is driven, and the loading kit 12 can also limit the position of the test unit component 14;

[0054] Subsequently, the test bearing 17 is sleeved on the outside of the locking ramp 16 and inserted into the limit kit 15 on the inside of the test unit component 14. Then, the set tapered bearing 18 can be sleeved on the outside of the test bearing 17 to ensure the smooth rotation of the test bearing 17 in the future, and the set bushing body 19 can contact with the outer ring of the tapered bearing 18, and then the locking nail passes through the locking screw hole 1501 and is connected to the bushing body 19, which can limit the outer ring of the tapered bearing 18, and the inner ring of the tapered bearing 18 is in contact with the test bearing 17, so that it can rotate with the test bearing 17 in the future, which can not only ensure the test shaft The smoothness of the rotation of the test bearing 17 can also ensure the stability of the test bearing 17. Then, the isolation ring 20 can contact the inner ring of the tapered bearing 18, and then the disassembly ring 21 is clamped on the outside of the isolation ring 20, and a plurality of sets of bolts pass through the disassembly ring 21 to connect with the locking port 1701 inside the test bearing 17, so as to lock the position of the test bearing 17, avoid the deviation and shaking of the test bearing 17, and further improve the stability of the test bearing 17. At the same time, the upper end of the isolation ring 20 does not contact the bushing body 19, and will not affect the normal rotation of the test bearing 17. Then, the installation cover 22 can be embedded in the limit sleeve The inner wall of the limiting kit 15 can be connected to the bushing body 19, thereby ensuring the tightness of the connection between the bushing body 19 and the outer ring of the tapered bearing 18. Then, the position of the mounting cover 22 is limited by screws to avoid the displacement and shaking of the mounting cover 22, which affects the subsequent processing.
