[0026] Combine the following Figure 1 , Figure 2 The technical solution provided by the utility model is described in more detail.
[0027] like Figure 1 and Figure 2As shown, the yaw bearing oil collecting bottle assembly provided by the utility model includes an oil collecting bottle body 1, an adapter and an extension tube 2, wherein: the oil collecting bottle body 1 is detachably connected to the adapter, a fluid channel is provided in the adapter, the extension tube 2 is located above the brake disc, one end of the extension tube 2 is detachably connected to the bearing oil drain port 6, and the other end is connected to the adapter, so as to be connected to the oil collecting bottle body 1 through the fluid channel, so as to guide the oil into the oil collecting bottle body 1.
[0028] The yaw bearing oil collecting bottle assembly of the present embodiment fixes the adapter on the oil collecting bottle body 1, and the extension tube 2 is connected to the adapter, so as to communicate with the oil collecting bottle body 1 through the fluid channel, and the oil can enter the oil collecting bottle body 1 normally. The extension tube 2 will change the position of the oil collecting bottle body 1, so that the oil collecting bottle body 1 is no longer located above the brake disc, thereby preventing the oil collecting bottle body 1 from overflowing grease and contaminating the brake disc, reducing the probability of yaw abnormal noise, and improving the surrounding sound environment and unit stability.
[0029] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the adapter includes a screw member 3 and an elbow member 5, wherein: there is an axial cavity 401 in the screw member 3, there is a connecting cavity 501 in the elbow member 5, the screw member 3 is threadedly connected to the oil collecting bottle body 1, one end of the elbow member 5 is threadedly connected to the screw member 3, the axial cavity 401 is connected to the connecting cavity 501, thereby constructing a fluid channel, and the other end of the elbow member 5 is threadedly connected to the extension tube 2.
[0030] See also Figure 2 As shown, the above-mentioned “fluid channel” refers to the cavity connecting the shaft cavity 401 and the connecting cavity 501 , and the oil in the bearing oil drain port 6 can flow into the oil collecting bottle body 1 through the extension tube 2 and the fluid channel.
[0031] The above-mentioned adapter facilitates the oil collecting bottle to be connected to the extension tube 2, so that the extension tube 2 supports the oil collecting bottle beside the brake disc instead of being located above the brake disc.
[0032] As an alternative embodiment, see Figure 2 As shown, the two ends of the elbow member 5 are respectively provided with a first assembly cavity 51 and a second assembly cavity 52 which are connected with the connecting cavity 501, the upper end of the screw member 3 extends into the first assembly cavity 51 and is threadedly connected with the first assembly cavity 51, and the end of the extension tube 2 extends into the second assembly cavity 52 and is threadedly connected with the second assembly cavity 52.
[0033] The above structure facilitates the detachable connection between the elbow member 5 and the screw member 3 , while allowing the axial cavity 401 of the screw member 3 to communicate with the connecting cavity 501 of the elbow member 5 , so that the oil can smoothly enter the oil collecting bottle body 1 through the extension tube 2 .
[0034] As an optional embodiment, the bending angle of the elbow piece 5 is 90°.
[0035] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the oil collecting bottle body 1 includes a bottle body 11 and a cover body 12 , wherein: the bottle body 11 is threadedly connected with the cover body 12 , an internal threaded hole is provided on the cover body 12 , and the screw member 3 passes through the internal threaded hole and is sealedly connected with the cover body 12 .
[0036] The above structure can realize the communication between the oil collecting bottle and the inner axial cavity 401 of the screw member 3 and the oil collecting bottle body 1 through the threaded connection between the cover body 12 and the screw member 3 .

[0038] The nut member 4 can improve the stability of the connection structure between the screw member 3 and the cover body 12 , so that the oil can smoothly enter the oil collecting bottle body 1 through the extension tube 2 .
[0039] As an alternative embodiment, see Figure 1 As shown, the extension tube 2 is an externally threaded tube and is threadedly connected to the bearing oil drain port 6, which facilitates the disassembly and assembly of the extension tube 2.
[0040] As an alternative embodiment, see Figure 1 As shown, the extension tube 2 is a straight tube structure with a simple structure, which facilitates the smooth flow of oil.
[0041] See also Figure 1 and Figure 2 As shown, the yaw bearing oil collecting bottle assembly of the present embodiment solves the problem that when the grease in the yaw bearing oil collecting bottle overflows, waste grease drips onto the brake disc, contaminating the brake disc and causing abnormal yaw noise. In the current working state, there is a phenomenon that waste grease overflows from the exhaust hole of the oil collecting bottle and contaminates the yaw brake disc. When the brake disc is oily, it will produce a harsh abnormal noise during the yaw process accompanied by high-frequency vibration, causing noise pollution and affecting the vibration signal detection of the unit. The yaw bearing oil collecting bottle assembly of the present embodiment eliminates the possibility of grease overflowing from the oil collecting bottle body 1 and contaminating the brake disc, by changing the fixed position of the oil collecting bottle body 1, thereby reducing the probability of abnormal yaw noise, and improving the surrounding sound environment and the stability of the unit.
