To achieve these goals, technical scheme of the present invention is:
A kind of tilting-pad bearing inside diameter measurement instrument, comprise axis body: on described axis body, be disposed with top, go side, measuring section, not-go-end and end, the diameter d of described go side is set to the minimum-value aperture in tilting-pad bearing hole, described measuring section is provided with tapering t, t=1:8000～1:10000, and on measuring section, be carved with the scale value line within the scope of tilting-pad bearing hole tolerance, the diameter D of described not-go-end is set to the maximum diameter of hole in tilting-pad bearing hole.
Further, after described axis body adopts common tool steel by Quenching Treatment, grinding tapering is made.
The measuring method in tilting-pad bearing aperture, comprises the following steps:
1) measure tilting-pad bearing aperture a:
Top on axis body is started in importing tilting-pad bearing hole gently from the large end of tilting-pad bearing, until tilting-pad bearing is stuck on axis body, check that the large end end face of tilting-pad bearing rests on the position on axis body and reads corresponding scale value can record tilting-pad bearing aperture a;
2) observe tilting-pad bearing hole circle degree situation:
On the cylindrical of the measuring section on axis body, coat red lead powder, top on axis body is started in importing tilting-pad bearing hole gently from the large end of tilting-pad bearing, until tilting-pad bearing is stuck on axis body, then axis body is derived from tilting-pad bearing hole, according to the position that is rubbed off red lead powder by tilting-pad bearing hole on axis body, can judge the circularity situation in tilting-pad bearing hole;
3) measure the right alignment of tilting-pad bearing hole and bearing body cylindrical:
Top on axis body is started in importing tilting-pad bearing hole gently from the large end of tilting-pad bearing, until tilting-pad bearing is stuck on axis body, the tilting-pad bearing being stuck on axis body is installed on axiality measuring apparatus together with axis body, reads the right alignment of tilting-pad bearing hole and bearing body cylindrical.
Useful technique effect of the present invention is: tilting-pad bearing inside diameter measurement tool construction of the present invention is simple, simple to operate, manufacture difficulty and low cost of manufacture; By the scale on survey instrument cylindrical, can intuitively record tilting-pad bearing aperture size; On the cylindrical of the measuring section of survey instrument, coat red lead powder, can effectively check the situation of the tilting-pad bearing hole circle degree that several tile fragments form automatically; Also can utilize this survey instrument to pass through axiality measuring apparatus together with tilting-pad bearing, detect the automatic tilting-pad bearing hole forming of several tile fragments and the right alignment of bearing body cylindrical.
