Description
technical field [0001] The invention belongs to the technical field of wind power bearings, and mainly relates to a detection device for the friction force between a spacer block and a steel ball of a yaw bearing. Background technique [0002] The spacer blocks used in wind power yaw bearings have different curvatures depending on the gauge value of the steel balls. During the design, production and use of the bearing, the structure of the spacer must ensure that it has a certain load-carrying capacity and at the same time isolates the steel balls without generating abnormal relative friction. The tightness between the spacer block and the steel ball, the roughness of the spacer block, the gap between the spacer block and the steel ball, and the lubricating grease between the spacer block and the steel ball will all affect the friction between the spacer block and the steel ball, and the spacer block The curvature and ellipticity of the mating surface with the steel ball ar...
