A method for lubricating and cooling splines of a wind power gearbox

Abstract

The invention relates to a method for lubricating and cooling a spline of a wind power gear box. The method is characterized in that when the wind power gear box is assembled, a circle of a circumference gap is formed between a sun gear and a pressing plate for the sun gear; two holes which form an included angle being 27 degrees together with the axis of the sun gear are symmetrically formed in a spline sleeve on the right side of an engaged part of an inner spline and an outer spline of the sun gear and the spline sleeve according to the axis of the sun gear; lubrication oil flows into the engaged part of the inner spline and the outer spline through the gap between the sun gear and the pressing plate for the sun gear so as to lubricate the inner spline and the outer spline; when the holes in the spline sleeve are rotated to the lower position with a workpiece, the lubrication oil flowing into the engaged part of the inner spline and the outer spline flows out from the holes, so that the oil liquid is circulated. The method provided by the invention has the advantages of simple mechanical structure, low difficulty in machining and manufacturing and low assembly difficulty; the problems caused by poor machining precision are avoided; the purpose of lubricating and cooling the spline can be realized without additionally arranging lubricating and cooling parts, so as to ensure that the temperature is normal when the spline transmits a torque.

Description

technical field [0001] The invention relates to a spline lubricating and cooling method of a wind power gearbox, belonging to the technical field of wind power gearboxes. Background technique [0002] In the wind power gearbox, the left end of the sun gear is a gear, the right end is an external spline, and the spline sleeve is provided with an internal spline. These two parts are assembled together to make the internal and external splines mesh. Generally, when considering the lubrication and cooling of gearboxes, the focus is on the lubrication of gears and bearings, and the lubrication and cooling of splines are often ignored. In fact, when splines transmit torque, the temperature is very easy to rise, and even glueing occurs. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a simple and effective method for lubricating and cooling the splines of the wind power gearbox, so as to ensure reliable operation o...
