Jig assembly and wear measuring device including the same

[0001] The present invention relates to a jig assembly and a wear measuring device including the same.

[0002] This research is related to the development of a high-durability 3-row roller pitch bearing for a 6MW wind turbine to meet the performance requirements of overseas customers under the New and Renewable Energy Core Technology Development (Power) project, which was carried out by CS Bearing Co., Ltd. with funding from the Ministry of Trade, Industry and Energy (Government) and support from the Korea Institute of Energy Technology Evaluation and Planning (KIET) (Project No.: RS-2023-00302111, Research Period: 2025.01.01 ~ 2025.12.31).

[0003] The bearing seals of a wind turbine play a role in reducing bearing friction by preventing lubricant leakage and the ingress of foreign matter. The lifespan of these bearing seals can be predicted through performance testing. The performance testing of the bearing seals may be a performance test of the material. In addition, the performance testing of the bearing seals can be performed while they are mounted on an actual wind turbine.

[0004] However, conventional performance testing of materials has the problem that it cannot simulate the actual operating conditions of the bearing seal. In addition, while performance testing when mounted on an actual wind turbine can provide high accuracy in lifespan prediction, there are problems such as the test time being very long and the cost of mounting the bearing seal on the wind turbine being high.

[0005] Accordingly, to predict the lifespan of bearing seals, it is necessary to develop a measuring device capable of simulating actual rotational speed conditions and conducting acceleration experiments.

[0039] Hereinafter, the jig assembly (30) of the present invention and the wear measuring device (1) including the same will be described with reference to the drawings.

[0040] Referring to FIGS. 1 to 3, the wear measuring device (1) can analyze the wear rate of a bearing seal (20) to predict the lifespan of the bearing seal (20). The wear measuring device (1) may include a measuring instrument (10), a bearing seal (20), and a jig assembly (30).

[0041] The measuring device (10) is a device for supporting the jig assembly (30) and analyzing the wear rate of the bearing seal (20). The measuring device (10) may include a measuring body (11), a rotating plate (12), a jig support part (13), a weight (14), and a controller (15).

[0042] The measuring body (11) can support the rotating plate (12) and the jig support (13). The measuring body (11) can provide the appearance of the measuring instrument (10). Additionally, the measuring body (11) may include a driving unit and circuits for driving the rotating plate (12).

[0043] The rotating plate (12) can be rotatably positioned around a rotation axis extending in the vertical direction on the measuring body (11). The rotating plate (12) can be positioned on the upper surface of the measuring body (11). Additionally, the rotating plate (12) can support the disc (100) to be described later.

[0044] The jig support member (13) may be positioned on the measuring body (11) to support the jig assembly (30). The jig support member (13) may be positioned on the upper surface of the measuring body (11) to support the jig assembly (30) so that the jig assembly (30) is spaced apart from the upper surface of the measuring body (11). The jig support member (13) may include a body extension member (13a) and a jig support member (13b).

[0045] The body extension member (13a) can extend upward from the measuring body (11) to support the jig support member (13b). The body extension member (13a) can be positioned so as to be spaced apart from the disc (100) and the rotating plate (12).

The jig support member (13b) may be supported by the body extension member (13a) so as to be spaced upward from the measuring body (11). Additionally, the jig support member (13b) may be positioned higher than the disc (100). When viewed from above, at least a portion of the jig support member (13b) may be positioned to overlap with the disc (100). Furthermore, a jig assembly (30) may be supported on one side of the jig support member (13b).

The center of rotation of the jig support member (13b) can be positioned to be closer to the other side opposite to one side of the jig support member (13b) than to one side of the jig support member (13b).

[0047] A weight (14) can be supported on the jig support member (13b) so that the jig support member (13b) is oriented in a horizontal direction. A plurality of weights (14) may be formed. One of the plurality of weights (14) may be placed on one side of the jig support member (13b). In other words, one of the plurality of weights (14) may be fastened to the main vertical member (212) and placed on the upper surface of one side of the jig support member (13b) to press one side of the jig support member (13b) downward. Another of the plurality of weights (14) may be placed on the other side opposite to one side of the jig support member (13b) to press the other side of the jig support member (13b) downward. The weight (14) can prevent the jig support member (13b) from shaking due to the rotation of the rotating plate (12).

[0048] A controller (15) may be placed on one or more of the measuring body (11) and the jig support (13) to control the rotation of the rotating plate (12). For example, the controller (15) may control the rotation of the rotating plate (12) to rotate at a rate of 1 rpm or more and 110 rpm or less.

[0049] Additionally, the controller (15) may be configured to measure the vertical load applied to the jig assembly (30) by one or more of the jig support (13) and the weight (14), and the frictional force applied to the bearing seal (20) by the rotation of the rotating plate (12). For example, the controller (15) may include a load cell indicator. Additionally, the controller (15) may calculate a friction coefficient based on the measured vertical load and frictional force. Based on this calculated friction coefficient, the user can predict the lifespan of the bearing seal (20).

[0050] The bearing seal (20) is placed on the bearing to prevent foreign matter from entering the bearing and to prevent the lubricant injected into the bearing from leaking out.

[0055] The disc (100) can be rotated around a rotation axis extending in the vertical direction. As the disc (100) rotates, it can wear out the contacted bearing seal (20). The disc (100) can be stacked on the rotating plate (12) and rotated by the rotation of the rotating plate (12). In other words, the disc (100) and the rotating plate (12) can be rotated together around the same rotation axis.

[0062] The main vertical member (212) may extend upward from the upper surface of the main horizontal member (211). This main vertical member (212) may be fastened to the jig support member (13b). As the main vertical member (212) is supported by the jig support member (13b), the main jig portion (210) may be spaced upward from the disc (100). Additionally, the main vertical member (212) may be fastened to one or more weights (14) supported on one side of the jig support member (13b) by passing through them. A vertical fastening hole (212a) may be formed in the main vertical member (212).

For example, the horizontal fastening part (300) may include a screw. By this horizontal fastening part (300), the seal fixing part (220) can be fixed to the main horizontal member (211). As the position where the horizontal fastening part (300) is inserted into the horizontal hole (211c) and the connecting hole (223a) approaches one side of the main horizontal member (211), the distance between the seal fixing part (220) and one side of the main horizontal member (211) can be reduced. Additionally, as the position where the horizontal fastening part (300) is inserted into the horizontal hole (211c) and the connecting hole (223a) is spaced further from one side of the main horizontal member (211), the distance between the seal fixing part (220) and one side of the main horizontal member (211) may increase.
