Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 and figure 2 As shown, a spline connection lubrication and cooling system 100 for a wind power gearbox includes: a spline shaft 10 , a sun gear 20 , an oil pump gear 40 and a transparent cover 50 .

[0025] The spline shaft 10 and the sun gear 20 are connected by splines. The oil pump gear 40 is connected to the spline shaft 10 . The spline shaft 10 , the sun gear 20 and the oil pump gear 40 all rotate relative to the transparent cover 50 . Specifically, the transparent cover 50 is fixed to the box body of the speed-up box and is in a static state. The transparent cover 50 is a fixed part. The spline shaft 10, the sun gear 20 and the oil pump gear 40 are moving parts and are in a state of rotary motion.

[0026] An oil storage cavity 21 is provided between the spline shaft 10 and the sun gear 20 . In other word...

Abstract

The invention discloses a wind power speed increasing box spline connection lubricating and cooling system which comprises a spline shaft, a sun gear, an oil pump gear and a permeable cover; an oil storage cavity is arranged between the spline shaft and the sun gear; the spline shaft is provided with a first oil return channel communicated to the oil storage cavity and used for discharging oil inthe oil storage cavity; the oil pump gear is provided with a second oil return channel which is communicated with the first oil return channel and is used for discharging oil in the first oil return channel; and the permeable cover is provided with a third oil return channel communicated with the second oil return channel and used for discharging oil in the second oil return channel and an oil outlet used for discharging oil in the third oil return channel. Oil enters the oil storage cavity from the oil inlet, sequentially flows through the first oil return channel, the second oil return channel and the third oil return channel and is discharged from the oil outlet; and splines of the spline shaft and the sun gear are submerged with lubricating oil. The wind power speed increasing box spline connection lubricating and cooling system has the beneficial effects that heating abrasion of internal and external splines in the running process are effectively reduced, and the service life of spline connection is ensured.

Description

technical field [0001] The invention relates to a spline connection lubricating and cooling system of a wind power speed-up box, in particular to a spline-connected lubricating and cooling system of a large-megawatt wind power speed-up box. Background technique [0002] The transmission form of a megawatt wind power gearbox usually includes a planetary gear train, generally a 2K-H type epicyclic gear train; the main structural types include a planetary + two parallel stage structure, a two planetary stage + a parallel stage structure. The transmission from planetary level to planetary level and from planetary level to parallel level usually adopts the connection form of spline. And in the planetary gear system, the design of the sun gear must ensure that there is a certain amount of radial floating, so as to ensure the load balance when the planetary gear and the sun gear mesh. [0003] During the operation of the large-megawatt wind power gearbox, the spline connection bet...
