Measurement of geometric deviation of shaft parts belongs to what measurement method

Measurement of geometric deviation of shaft parts belongs to the measurement method of perpendicularity detection of the plane of shaft parts to the reference axis.

The perpendicularity of the plane of the shaft parts to the reference axis can be detected by using the detection of the perpendicularity of the end face to the reference axis, the detection of the perpendicularity of the stepped plane to the reference axis, and the detection of the perpendicularity of the axis of the outer circle to the reference plane.

The detection of parts measured axis for the benchmark axis of coaxiality can be used to measure the axis relative to the benchmark axis coaxiality error, the measurement of the axis relative to the two ends of the cylindrical metric **** benchmark axis of coaxiality error to measure.

Measurement of the surface of the part relative to the reference axis of the circular runout error can be used to measure the surface of the shaft for the two ends of the external cylindrical surface of the radial circular runout error of the metric **** axis, the measurement of the shaft end face for the reference axis of the end face circular runout error to measure.

In industrial products, shaft parts are suitable for use in one or more CNC machine tool machining parts maintenance operations. They are used in machines to support transmission parts such as gears and pulleys to transmit torque or motion. Shaft parts are rotating body parts, whose length is greater than their diameter, and are generally composed of concentric shafts with external cylindrical surfaces, conical surfaces, internal bores and threads and corresponding end faces.

The length to diameter ratio of the shaft is less than 5 is called the short shaft, more than 20 is called the slender shaft, most shafts between the two. Shaft with bearing support, and bearing with the shaft segment called journal. Journal is the assembly of the shaft benchmark, their accuracy and surface quality generally require high, its technical requirements are generally based on the main function of the shaft and working conditions.
