Problems solved by technology

In order to reduce the wear and energy loss of the gears during the transmission process, it is necessary to keep the gears in a lubricated state at all times; and the multiple gears that constitute the wind power transmission device are usually arranged in a housing. If the housing is disassembled to lubricate the internal gears, not only It is very troublesome and will affect the accuracy of the wind drive

Embodiment Construction

[0017] Attached below Figure 1~3 The present invention is further described.

[0018] A wind power transmission device, including a multi-stage transmission part arranged in a casing 1, the transmission part includes a central shaft 2 and two gears 3 fixed on the central shaft 2, the two gears on the central shaft 2 3 is a large gear 6 and a small gear 5; the upper and lower ends of the central shaft 2 pass through the housing 1, and are respectively connected to the top and bottom of the housing 1 through rolling bearings 4 in rotation. The pinion 5 of the transmission part meshes with the bull gear 6 of the upper stage transmission part, and the pinion 5 of the first stage transmission part meshes with the power input shaft, and the big gear 6 of the last stage transmission part meshes with the rotor of the generator engage. It should be understood that the power input shaft drives the first-stage transmission part to rotate through the pinion 5 meshing with it, and the l...

Abstract

The invention relates to the technical field of wind power generation equipment and provides a wind power transmission device convenient for lubricating gears. The wind power transmission device comprises multistage transmission parts arranged in a shell, each transmission part comprises a central shaft and big and small gears fixed on the central shaft, and the upper and lower ends of each central shaft are rotatably connected with a shell; an oil delivery port is arranged at the top end of each central shaft, multiple oil outlets are uniformly arranged on a tooth face of each gear and communicated with the corresponding oil delivery port through an oil delivery passage, a portion, positioned in the corresponding gear, of each oil delivery passage extends from the center to the edge in anobliquely downward manner, and steel balls for controlling opening and closing of the oil outlets are arranged inside each oil delivery passage. The gears inside the shell can be lubricated without disassembling the shell.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a wind power transmission device. Background technique [0002] The wind power transmission device is an essential part of wind power generation equipment. The wind power transmission device can convert the low speed of the power input shaft into a high speed, thereby driving the rotor of the generator to generate electricity. The wind power transmission device is usually composed of multiple gears, and the gears are meshed in sequence to realize the conversion of the rotational speed. In order to reduce the wear and energy loss of the gears during the transmission process, it is necessary to keep the gears in a lubricated state at all times; and the multiple gears that constitute the wind power transmission device are usually arranged in a housing. If the housing is disassembled to lubricate the internal gears, not only It is very troublesome, and it wil...
