Description

Technical Field

[0001] The utility model relates to the technical field of double-shaft oil washing of gear boxes, in particular to a double-shaft oil washing device for gear boxes. Background Art

[0002] Gearboxes are widely used, for example, in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transmit the power generated by the wind wheel under the action of wind to the generator and make it obtain the corresponding speed. Usually, the speed of the wind wheel is very low, far from the speed required for the generator to generate electricity. It must be achieved through the speed increase effect of the gearbox gear pair, so the gearbox is also called a speed increaser. When processing and producing the gearbox, it is usually necessary to perform oil washing on the double shafts of the gearbox. During oil washing, the double shafts of the gearbox can be oil washed by connecting oil washing pipes at both ends of the gearbox and then pumping oil into the gearbox for flushing. Since the gearbox is generally placed on a support plate during oil washing, and then the oil washing pipes are connected at both ends, and the gearbox is not driven, the oil washing of the double shafts of the gearbox is not thorough enough, and there is a phenomenon of poor oil washing effect in dead corners. Therefore, a double shaft oil washing device for a gearbox is proposed to address the above problems. Utility Model Content

[0022] Example 2

[0023] like Figure 1-2 As shown, in order to solve the problem of inconvenience in filtering the oil after the gear box double shaft oil washing, the right end of the oil tank 6 is connected with a fixed pipe 7 that penetrates the fixed box 1, and the fixed pipe 7 is fixedly connected to the fixed box 1, and the other end of the fixed pipe 7 is connected with a filter box 8 that is fixedly connected to the fixed box 1, and the top of the filter box 8 is connected with an oil inlet pipe 9, and a filter screen 10 is placed inside the filter box 8. By allowing the oil after the gear box double shaft oil washing to pass through the filter screen 10 in the filter box 8, it is convenient to filter the oil after the gear box double shaft oil washing.

By inserting the shaft of the gear box into the sleeve 16 at the right end of the fixed shaft 14, it is convenient to drive the impeller 15 to rotate the shaft of the gear box through the fixed shaft 14.

[0026] Example 4

[0027] like Figure 1-3 As shown, in order to solve the problem of poor stability during oil washing of the double shafts of the gear box, a fixing seat 17 is slidably connected to the inner right end of the fixing plate 2, and an extrusion block 19 is slidably connected to the inner top end of the fixing seat 17.

[0030] In this embodiment, when the double shafts of the gear box are oil-washed by the device, the gear boxes of different models are placed on the top of the fixed seat 17, and then the two-way threaded shaft 22 with opposite thread directions on both sides is rotated to be spirally connected with the slider 21, so that the gear box on the top of the fixed seat 17 is pushed up and down during the rotation of the rotating rod 20. When the shaft of the gear box is facing the sleeve 16, the threaded shaft 18 is rotated to be spirally connected with the extrusion block 19 to squeeze the gear box tightly on the top of the fixed seat 17, so as to ensure that the shaft of the gear box is inserted into the sleeve 16 at the same time. After completing the above operations, the oil outlet pipe 13 and the oil inlet pipe 9 are respectively connected to the oil inlet of the gear box. The oil inlet and the oil outlet are connected, and then the oil pump 4 is started through the controller 3. At this time, the oil in the oil tank 6 is extracted by the oil pump 4 through the oil extraction pipe 5, and then sprayed to the impeller 15 through the delivery pipe 11, and the impeller 15 is further driven to drive the fixed shaft 14, the shaft sleeve 16 and the shaft of the gear box to rotate. The sprayed oil is flushed into the gear box through the oil outlet pipe 13, and then discharged into the filter box 8 through the oil inlet pipe 9 and filtered through the filter screen 10, and then flows back to the oil tank 6 through the fixed pipe 7, thereby realizing the flushing and oil washing of the double shafts of the gear box in the process of driving the gear box, so that the oil washing of the double shafts of the gear box is more thorough.
