Measuring tool and measuring method for tilting-pad bearing aperture

Abstract

The invention relates to a measuring tool, in particular to the measuring tool and a measuring method for a tilting-pad bearing aperture. The measuring tool comprises a shaft body, wherein a start end, a through end, a measuring section, a stop end and a tail end are arranged on the shaft body in sequence; a diameter d of the through end is arranged as a smallest aperture of a tilting-pad bearing hole; a taper t is arranged at the measuring section, t=(1:8000) to (1:10000), and scale value lines within a tolerance range of the tilting-pad bearing aperture are carved in the measuring section; a diameter D of the stop end is arranged as a largest aperture of the tilting-pad bearing hole. The measuring method comprises the following steps: guiding the start end on the shaft body to the tilting-pad bearing hole from a larger end of a tilting-pad bearing until the tilting-pad bearing is clamped on the shaft body; reading a corresponding scale value, on the shaft body, of the tilting-pad bearing, wherein the read corresponding scale value is the aperture of the tilting-pad bearing. The measuring tool and the measuring method, for the tilting-pad bearing aperture, provided by the invention is simple in structure, low in manufacturing cost, and simple in measuring method.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a measuring tool and a measuring method for an aperture of a tilting pad bearing. Background technique [0002] Centrifugal aeration blower is a high-end impeller mechanical equipment. Due to the limitation of technological advancement and manufacturing complexity, currently, only a few countries in the world can produce high-quality centrifugal aeration blower. The centrifugal aeration blower is a high-speed rotating device, and the high-speed rotating main shaft in the core structure must be supported by a supporting bearing with good performance. It can be seen that the support bearing plays a vital role in the efficiency of the centrifugal blower. At present, the support bearing with better quality is the tilting pad bearing, which not only solves the problem of good mechanical performance, but also improves the service life of the bearing. , but this type of bearing pos...

Problems solved by technology

During the machining of tilting pad bearings, it is difficult to measure the high-precision bearing hole size and geometric tolerance. The usual measurement methods cannot measure the size of the base circle formed automatically by the pad, including inner diameter micrometers, three-coordinate measuring instruments, and vernier calipers. , it is difficult to guarantee the processing quality of the tilting pad bearing
