Assembly test table of pivoting support of windmill generator

Abstract

The invention relates to an assembly test table of a pivoting support of a windmill generator, belonging to test equipment, which is characterized by mainly comprising a base, a reducer, a cylinder, a pinion, the pivoting support, a cross slider, a test workbench, a cavity stand column, a cushion block, a sliding sleeve, a bracket, a measuring arm, a moment sensor and a computer, wherein the upper platform of the hollow base is provided with an external gear type pivoting support; the left side part of the upper platform is provided with the reducer to drive the external ring of the gear type pivoting support; the upper plane of the external ring is provided with the test workbench; the cylinder is arranged on the bottom surface of the upper platform; the cavity stand column is arranged on the upper surface of the upper platform; the cross slider is arranged on the piston rod of the cylinder in a rotating manner; the left side and the right side of the slider are respectively provided with a support shaft in a rotary manner; the sliding sleeve is arranged on the cavity stand column in a sliding manner and supports on the support shaft; the upper end section of the sliding sleeve is welded with a rectangular bracket; and the top end of the cavity stand column is provided with the moment sensor which is provided with the measuring arm and is connected with the computer, thus having convenient operation and high test precision.

Description

technical field [0001] The invention belongs to testing equipment, in particular to a testing platform for a wind power generator slewing bearing. Background technique [0002] Wind turbine slewing bearings generally require that the inner and outer rings pass through the rolling element interference assembly between the inner and outer rings, and the relative rotation resistance torque of the inner and outer rings must be within the specified range. In order to meet the above requirements, wind power Generator slewing bearings must detect the gap between the inner and outer rings and the slewing resistance torque. Since the production history of wind turbine slewing bearings in China is very short, the current detection process is to use the horizontal hoisting of the inner ring or outer ring of the slewing bearing. To measure the axial clearance between the inner and outer rings, and manually measure the rotational resistance torque between the inner and outer rings with a...

AI Technical Summary

Problems solved by technology

[0003] 1. It is time-consuming to put three slings on the workpiece to be measured by driving and lifting, which is not suitable for mass production, and the speed of driving and lifting is fast, which affects the measurement accuracy

[0004] 2. It is difficult to measure the continuous rotation resistance torque within 360° by manually measuring the rotational resistance torque between the inner and outer rings through the tension meter, which is inefficient and labor-intensive for workers
