Bearing radial internal clearance measurement component and method for measuring radial bearing internal clearance

Abstract

The invention discloses a bearing radial internal clearance measurement component and method for measuring radial bearing internal clearance, and belongs to the field of bearing measurement. A bearing radial internal clearance measurement component comprises a supporting block, a buckling block and a dial indicator; the upper surface of the supporting block is provided with a groove for placing the bearing, and the middle part of one side of the buckling block is provided with a buckling groove for buckling a bearing inner ring; the base of the dial indicator is arranged on the buckling block, and a measuring head of the dial indicator is used for leaning at the outside of a bearing outer ring. The bearing radial internal clearance measurement component is more accurate to measure the radial internal clearance of a large bearing; the bearing radial internal clearance measurement component and method are particularly suitable for yaw, variable pitch and other large bearings of a wind turbine generator; moreover, the bearing radial internal clearance measurement component is simple in structure, and easy to mount and dismount.

Description

technical field [0001] The invention relates to the field of bearing clearance measurement, in particular to a radial clearance measuring component and a method for measuring the bearing clearance, which are particularly suitable for large-scale bearings such as yaw and pitch bearings of wind power generating sets. Background technique [0002] In the yaw and pitch bearings of wind turbines, especially large megawatt wind turbines, the radial clearance of the bearing is an important technical index of the bearing, which directly affects the service performance and life of the bearing. If the clearance is too large, the rolling elements will slip; if the clearance is too small, the heat generated by the bearing will increase during use, causing the bearing to burn or even get stuck. Therefore, it is of great significance to accurately understand the radial clearance of the wind turbine yaw and pitch bearings during use. [0003] The yaw and pitch bearings of wind turbines mo...
