Double-row same-diameter four-point contact ball slewing bearing groove center distance tester for wind power

Abstract

The invention belongs to the technical field of bearing detection, and proposes a double-row, same-diameter, four-point contact ball turntable bearing groove center distance detector for wind power, which has a main support rod 4 and a movable support rod 3 hinged on the upper part of the main support rod 4, which is movable and supported One end of the rod 3 is connected with a measuring disc 2, which constitutes a structure in which the measuring disc 2 can swing up and down relative to the main support rod; There is a measuring disc 2, which constitutes a structure in which the fixed rod 11 can move along the long strip hole of the main support rod, and the measuring disc can be adjusted up and down with the fixed rod; the diameter of the measuring disc 2 is the same as that of the bearing steel ball to be measured : the measurement of the main support bar 4 upper end is provided with the dial indicator 7 and its table head contacts with the other end of the movable support bar 3. The measuring instrument of the invention can satisfy the detection of the groove center distance and the mutual difference of the groove center distance of the measured bearing; accurately reflect the groove center distance of the inner and outer rings, the parallel difference and the mutual difference of the groove center distance.

Description

technical field [0001] The invention belongs to the technical field of bearing detection, and relates to a double-row, same-diameter, four-point contact ball turntable bearing groove center distance detector for wind power. Background technique [0002] With the relative scarcity of traditional energy and the increasing environmental pressure, countries are increasing their investment in the development of renewable energy including wind power. At present, the wind power industry has spread to all continents of the world and is showing a rapid growth trend. Especially in recent years, the development of the global wind power industry has been fierce, the market demand for wind power equipment is promising, and the development prospects of the supporting bearings for wind turbines are showing a thriving scene. The rapid growth of the wind power industry has provided strong support for the development of wind power equipment. In the past 10 years, my country's large-scale wi...

Problems solved by technology

At this stage, since there is no direct measurement equipment for the distance between the inner and outer ring double grooves, CNC machine tools are often used to ensure or indirect measurement by adding balls, and the measurement error is relatively large, which restricts the overall quality level of this type of bearing
