Measuring device and measuring method of raceway position of large slewing bearing

Abstract

The invention discloses a measuring device of raceway position of a large slewing bearing. The outer surface of an inner ring and the inner surface of an outer ring of the slewing bearing are respectively provided with a channel; a steel ball raceway is formed by the combination of the inner ring and the outer ring of the bearing. The measuring device of the raceway position comprises a square rule, a template, a slide rule and a dialgauge, wherein, the square rule is provided with a perpendicular part and a horizontal part which is connected to the upper end of the perpendicular part and theend surface of which is provided with a mounting hole; the template is a semi-circle plate of which the diameter is equal to that of the steel ball; the slide rule is a square frame of which the height is equal to the diameter of the template, can be sheathed on the perpendicular part of the square rule in a sliding manner, and one side face of the slide rule is connected with the diametral planeof the template; the dialgauge is fixed at the upper part of the horizontal part of the square rule, and a measuring rod thereof passes through the mounting hole of the horizontal part downwards fromthe upper part of the square rule so as to ensure a contact of the measuring rod to press on the upper end surface of the slide rule. The measuring device can directly read out location dimension of the bearing raceway to be measured.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for a yaw bearing and a pitch bearing on a wind power generator, in particular to a measuring device and a measuring method for a raceway position of a large slewing support bearing. Background technique [0002] my country is entering into the new "green industry" of wind power generation. In order to improve the power generation efficiency and increase the power generation capacity of wind power generators, the length of the blades, the size of the main shaft, the speed increaser, the generator and other parts are also expanding, but At the same time, the load borne by the bearings is also gradually increasing, which has very high technical requirements for wind power bearings. The pitch bearings and yaw bearings on wind turbines are four-point contact ball bearings and double-row angular contact ball bearings, which require high channel size and position accuracy, and have high static...

Problems solved by technology

This method cannot quantitatively read the deviation value, and it can be used for single-row raceway bearings, but for double-row raceway bearings, the position and size deviation between one raceway and the other raceway is very demanding, and it cannot be detected by the light transmission method
