These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiment

[0060] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0061] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "counterclockwise", "clockwise", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

[0062] The bearings of the generators of wind turbines generally use grease for lubrication to prevent wear of the bearings. When maintaining the front and rear bearings of a wind turbine or when it is necessary to take a sample of the grease inside the bearings for testing, the operation of taking grease will be involved. After the staff loosens the screws on the generator bearing, the grease is taken out through the gap after loosening. The existing method of taking grease is to take it out by a putty knife or scraping by hand. This method of taking grease requires repeated operations to obtain a sufficient amount of grease. Sometimes the tool cannot fully reach into the inside of the bearing, and only the surface grease can be taken out, seriously affecting the quality of the grease. Moreover, the taken-out grease needs to be collected into an oil collecting bottle by a putty knife or by hand before it can be stored, which is time-consuming and unhygienic, seriously affecting the work efficiency.

[0063] An oil taking device for a wind turbine bearing provided by the present application aims to solve the technical problems in the prior art that during the process of taking grease samples of a wind turbine using a sampling tool, it is time-consuming, unhygienic, has low efficiency, and cannot take samples from the inside of the bearing. The hose in the oil collecting assembly of the present application can reach into the inside of the bearing, and the force applying assembly connected to the oil collecting assembly generates negative pressure inside the oil collecting assembly, and the grease inside the bearing is sucked into the oil collecting assembly through the hose, realizing efficient, time-saving and hygienic grease taking.
