Detection gauge for measuring horizontal angle of wind power main shaft bearing cage pocket

Abstract

This utility model belongs to the field of bearing technology and proposes a measuring tool for measuring the horizontal angle of the pocket holes in a wind turbine main shaft bearing. The measuring tool has two pocket detection blocks, I and II, inserted into the pocket holes. One end of pocket detection block I, located inside the bearing cage, is connected to an angle rotating rod via a connecting rod I. The other end of pocket detection block II, also located inside the bearing cage, is connected to the angle rotating rod via a connecting rod II. The lower end of the angle rotating rod is hinged to a base, and an angle gauge for real-time measurement of the angle of the angle rotating rod is fixed on the base. The base and the bearing cage being measured are both placed on the same marble platform. The base is located within the inner hole of the bearing cage. This utility model employs a structure where pocket detection blocks I and II are inserted into the pocket holes of the cage, combined with the angle rotating rod to directly measure the horizontal angle of the cage pocket holes, ensuring the accuracy of the test results.

Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, specifically relating to a measuring tool for measuring the horizontal included angle of the cage pocket of a wind turbine main shaft bearing. Background Technology

[0002] The main product structures currently used in wind turbine main shaft bearings include single-row tapered roller bearings, double-row tapered roller bearings, and double-row self-aligning roller bearings. Among them, the dimensional machining accuracy of the bearing cage is a key technical indicator for bearing operation. In particular, for tapered roller bearings, the machining accuracy of the horizontal included angle of the cage pocket directly affects the service life of the bearing. However, the horizontal included angle of the cage pocket cannot be directly measured, which makes it impossible to guarantee the accuracy of machining and testing. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a measuring tool for measuring the horizontal included angle of the cage pocket of the wind turbine main shaft bearing.

[0005] The connecting rod I is fixedly connected to the pocket detection block I by connecting screw I, and is mounted on the angle rotation rod by fastening screw I; the connecting rod II is fixedly connected to the pocket detection block I by connecting screw II, and is mounted on the angle rotation rod by fastening screw II.

[0006] This utility model proposes a measuring tool for measuring the horizontal angle of the cage pocket of a wind turbine main shaft bearing. It adopts the method of placing pocket detection block I and pocket detection block II into the cage pocket, and combines the angle rotation rod to directly measure the horizontal angle of the cage pocket, thus ensuring the accuracy of the test results.

[0011] The present invention will be described in conjunction with the accompanying drawings and specific examples: like Figure 1 As shown, a measuring tool for measuring the horizontal included angle of the cage pocket of a wind turbine main shaft bearing, combined with... Figure 1 The pocket detection block I1 is mounted on the connecting rod I6 by the connecting screw I3, the pocket detection block II2 is mounted on the connecting rod II8 by the connecting screw II4, the connecting rod I6 is mounted on the angle rotating rod 5 by the fastening screw I7, the connecting rod II8 is mounted on the angle rotating rod 5 by the fastening screw II9, the angle rotating rod 5 is fixed on the base 11, and the angle ruler 10 is fixed on the base 11.

[0012] When measuring the horizontal included angle of the cage pockets of the wind turbine main shaft bearing, the base 11 is placed horizontally on the marble platform 12, and the cage 13 is placed horizontally on the marble platform 12. The spacing between the pocket detection blocks I1 and II2 is adjusted according to the design dimensions of the cage pockets. The structures of the pocket detection blocks I and II2 are as follows: Figure 3 As shown, during measurement, the angle rotating rod 5 is rotated and adjusted so that the pocket detection block I1 and pocket detection block II2 are pushed into the pocket of the retainer 13. The horizontal angle of the retainer pocket can be accurately measured according to the reading of the angle ruler 10.
