[0035] Civil aircraft are equipped with integral transmission generators. The operation of IDG requires lubricating oil intervention, so IDG needs irregular lubricating oil service. When the amount of lubricating oil is lower than the maintenance standard, the IDG is refilled with lubricating oil. Taking the Boeing 737NG aircraft as an example, the method of refilling the IDG with lubricating oil is to use a lubricating oil filler dedicated to the IDG. The lubricating oil filler consists of three parts, including a metal oil tank for storing lubricating oil, a hand-cranked hydraulic pump device, a dedicated IDG refueling interface and a hose. When refilling lubricating oil is needed, first pour the new lubricating oil into the metal oil tank, use the refueling interface to connect with the IDG, and then manually hand-crank the hydraulic pump device. After the above work process, the lubricating oil in the oil tank flows from the metal oil tank into the hose under the hydraulic action of the hand-cranked hydraulic pump device, and then flows into the IDG, and finally completes the refueling work.

[0036] However, since the lubricating oil exposed to the air will combine with water vapor after being stored for a long time, the lubricating oil will deteriorate and cannot be used. According to the maintenance requirements of the manual, the lubricating oil added each time should be newly opened lubricating oil. Therefore, when using the lubricating oil filler, the maintenance personnel need to pour out the old lubricating oil in the oil tank, rinse and dry the oil tank, and then pour in the newly opened lubricating oil for filling. And after the filling work is completed, the remaining lubricating oil is poured out, rinsed and dried, and then reserved for the next filling work. The work process is very cumbersome and inconvenient. In addition, the current oil tank is not designed with an oil drain port, so when pouring out the old waste lubricating oil, it can only be poured out from the oil tank port. Because the lubricating oil is viscous, the lubricating oil will flow from the oil tank port to the surface of the oil tank, causing pollution and requiring cleaning. Because the lubricating oil is toxic, the maintenance personnel need to take protective measures before cleaning the surface of the oil tank. In addition, because the lubricating oil filler is composed of a metal oil tank, this oil tank is large in size and heavy in weight (the entire device is over 20KG when unloaded), and has poor portability. In addition, the oil fillers used in other fields are not fully applicable to the oil fillers of the 737 aircraft. For example, some open oil fillers are not designed to be waterproof and rainproof during the oil filling process. When the aircraft is filled with oil, it is often on the apron, sometimes in heavy rain. When the oil tank is opened in heavy rain, the oil is easily infiltrated with water during the filling process. The water will contaminate the oil and reduce the service life of the IDG. In addition, since the oil tank used in the 737 aircraft is relatively small, the existing oil fillers cannot fix the oil tank well. Since the hand-cranked pump needs to be shaken during the filling process, the entire oil filler shakes greatly and is prone to tipping over. In summary, the existing oil fillers have the problems of poor flexibility and stability.

[0037] Based on this, the present application proposes a lubricating oil filler, which includes a shed-type metal platform, a lubricating oil fixed base, a hand-cranked hydraulic pump device and a refueling interface. The shed-type metal platform cover is arranged on the lubricating oil tank. The shed-type metal platform is provided with a hollow circular ring hole, and the hollow circular ring hole is used to place the hand-cranked hydraulic pump device. The lubricating oil fixed base is composed of a metal plate, and a raised circular ring structure is provided on the side of the metal plate facing the shed-type metal platform, and the raised circular ring structure is used to fix the lubricating oil tank. This solution supports the entire device through a lubricating oil fixing base, and fixes the lubricating oil tank through a raised circular ring structure, which can well fix the lubricating oil tank during the process of filling the lubricating oil, so that the refueling work is suitable for windy weather or uneven road surface and many other special situations, and has strong flexibility and stability in use; in addition, by setting up a shed-type metal platform, rainwater can be well blocked from entering the lubricating oil tank, and the waterproof and rainproof function is good, which prevents rainwater from contaminating the lubricating oil, thereby extending the service life of the entire transmission generator; in addition, during the process of filling the lubricating oil, the lubricating oil tank can be used as a one-time oil tank and can be discarded after use, which not only reduces the tedious process of cleaning and drying the oil tank, but also ensures that the lubricating oil filled each time is fresh, further improving the service life of the entire transmission generator; in addition, the design of the oil tank is removed, and there is no need to pour out the waste oil, which will not cause pollution to the surface of the oil tank, and there is no need for the maintenance staff to clean the surface oil, which reduces the contact between the maintenance staff and the lubricating oil, protects the maintenance staff, and also reduces the overall weight and volume of the lubricating oil filler, and the weight can be designed to be within 8KG, which is easy to carry.

[0038] The following is combined with Figure 1 The lubricating oil filler according to the embodiment of the present application is described exemplarily.

[0072] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0073] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
