Embodiment Construction
[0020] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as Figure 1 to Figure 3 As shown, a filter system 100 of a wind power gearbox includes: a torque arm 10, a middle box 20 and an off-line filter system. The offline filtering system is used to filter the lubricating oil in the middle box 20 . Specifically, the offline filtering system includes: a filter 30 for filtering lubricating oil, an oil pump 40 , an oil suction pipe 50 and an oil return pipe 60 . The oil pump 40 delivers the lubricating oil in the middle box 20 to the filter 30 through the oil suction pipe 50 for filtering. The lubricating oil filtered in the filter 30 flows back into the gear box through the oil return pipe 60 to lubricate the transmission mechanism. Filtration of lubricating oil can avoid contamination in lubricating oil, causing wear of gears and other moving parts and affecting service life.

The invention discloses a filtering system of a wind power gearbox. The filtering system comprises a torque arm, a middle box body, a filter, an oil pump, an oil suction pipe and an oil return pipe, wherein the filter is used for filtering lubricating oil; an oil return hole for backflow of the lubricating oil is formed in the torque arm; an oil storage inner cavity containing the lubricating oilis formed in the middle box body; a low-point oil outlet channel for allowing the lubricating oil in the oil storage inner cavity to flow out is formed in the middle box body; an oil outlet allowing the lubricating oil in the oil storage inner cavity to enter the low-point oil outlet channel is defined on one end of the low-point oil outlet channel; the oil outlet is formed at the lowest point ofthe oil storage inner cavity of the middle box body; the low-point oil outlet channel communicates with one end of the oil suction pipe; the other end of the oil suction pipe communicates with the oilpump, the oil pump communicates with the filter; one end of the oil return pipe communicates with the filter, and the other end of the oil return pipe communicates with the oil return hole. Accordingto the filtering system of the wind power gearbox, the lubricating oil in the gearbox can be filtered to remove impurities deposited in the gearbox.
Description
technical field [0001] The invention relates to a filtering system, in particular to a filtering system of a wind power speed increasing box. Background technique [0002] During the operation of the traditional gearbox, tiny particles will be generated due to the friction between the bearing interior, gear meshing and other parts, and foreign pollutants will enter due to sealing defects. These contaminants reduce the cleanliness of the lubricating oil. When the gearbox is at rest, these contaminants settle in the lubricating oil at the bottom of the case. The cleanliness of lubricating oil plays a vital role in the lubrication of bearings and gear meshes. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a filter system for a wind power gearbox capable of filtering lubricating oil in the gearbox. [0004] In order to achieve the above object, the present invention adopts the following technical soluti...
