Description
Technical Field
The utility model relates to a lubricated cooling system of wind-powered electricity generation increaser spline connection especially relates to a lubricated cooling system of big megawatt wind-powered electricity generation increaser spline connection.
Background
the transmission form of the megawatt wind power speed increasing box usually comprises a planetary gear train which is generally a 2K-H type epicyclic gear train; the main structure type comprises a primary planet + two-stage parallel stage structure and a two-stage planet + primary parallel stage structure. The transmission from planet stage to planet stage and from planet stage to parallel stage usually takes the form of a splined connection. In the planetary gear train, the design of the sun gear ensures that a certain radial floating amount exists, so that the uniform load when the planetary gear is meshed with the sun gear is ensured.
When the large-megawatt wind power speed increasing box runs, the sun gear is connected with the parallel gears through the spline and is in a high-speed heavy-load state; at the same time, the rotational movement of the sun wheel has a certain amount of floating in the radial direction. Therefore, at the spline joint, fretting friction exists between the spline tooth meshing surfaces between the inner spline and the outer spline, so that a large amount of heat and fine particles are generated. At this point, excessive heat buildup and high concentrations of fine particulate matter will exacerbate wear of the spline teeth, leading to premature failure of the spline connection. Therefore, in the operation process of the spline connection, the key teeth of the spline are effectively lubricated and cooled, and the key teeth are of great importance for ensuring the operation life of the spline connection.
The spline connection lubrication system of the traditional wind power speed increasing box mainly has two types.
The first main lubrication mode is: the oil injection ring is provided with an oil injection hole, and lubricating oil is injected to the shaft neck at the front section of the external spline on the sun wheel by adjusting the angle of the oil injection hole; because the wind power speed increasing box is not horizontally arranged but obliquely arranged in the running process, a certain elevation angle exists. Thus, the lubrication oil sprayed on the sun gear journal will flow under gravity to the splined area due to the angle of inclination. An oil return hole is formed in the downwind tail end of the spline; after flowing through the spline meshing area, the lubricating oil flows back to the oil pool through the oil return hole, so that heat and tiny particles are taken away. This approach does not ensure that the lubricating oil continues to flow through all the key teeth to establish an effective oil film and carry away heat and fine particulate matter. Therefore, early failure of the male and female splines is easily caused.
The second main lubrication mode is as follows: an oil collecting cavity is established, and an oil inlet and an oil return hole are formed in the spline shaft to store lubricating oil flowing from the oil inlet into the oil collecting cavity; under ideal conditions, lubricating oil in the oil collecting cavity can uniformly flow through all key teeth and take away heat and tiny particles generated by spline fretting friction through the oil return hole in the lower direction. However, in the design process of the structure, multiple tests are needed, and the flow of the oil inlet and the size of the oil return opening are adjusted to ensure that enough lubricating oil can be effectively stored in the oil collecting cavity under the condition that the gear box runs stably, so that all key teeth can be effectively lubricated and cooled. Otherwise, the lubrication method still cannot ensure effective lubrication and cooling of all the key teeth, thereby leading to early failure of the spline.
