Problems solved by technology

At the same time, since there are roundness errors in the center holes at both ends, it is necessary to go to the gear testing center to detect
This measurement method is not only inefficient, but also inaccurate, especially in mass production of auto parts, it is not applicable at all

Embodiment Construction

[0010] Such as figure 1 and figure 2 As shown, the radial runout measuring instrument of the present invention with external splined ring gear includes a measuring table 1, an internal splined ring, an adjusting handle 2, an adjusting screw 3, a compression spring 4, a scale 5, a calibration piece 6, a base plate 7 and The support column 8 and the gauge 5 adopt a dial indicator, which is connected on the measuring platform 1 through the table base 9 and the nail screw 10. The measuring table 1 is supported on the bottom plate 7 by the support column 8 . The inner spline ring is installed on the measuring table 1 through a precision bearing 14, and it can rotate concentrically at will. The inner spline ring is assembled by spline one 11, spline two 12, spline three 13 and three coaxial inner splines. The first spline 11 and the third spline 13 are fixed together, the tooth shapes of the two splines are completely corresponding, and they cannot move relative to each other. ...

Abstract

The invention discloses a dial external spline gear ring radial pulsation measuring apparatus, which comprises a measuring stand, an internal spline ring, an adjusting handle, an adjusting screw, a pressure spring and a measuring indicator, wherein the internal spline ring and the measuring indicator are arranged on the measuring stand respectively; the internal spline ring is formed by assembling three coaxial internal splines, namely a first spline, a second spline and a third spline; the first spline and the third spline are fixedly connected with each other and have completely corresponding tooth shape; the second spline is movably connected between the first spline and the third spline and can perform concentric rotation; the adjusting handle is inserted into the second spline and the third spline; and the adjusting screw and the pressure spring are arranged inside concave holes which are arranged inside the second spline and the third spline. The measuring apparatus has the advantages of convenient, accurate and direct measurement, easy maintenance, low requirement on a measuring environment, low cost, high efficiency and the like, and is particularly suitable for mass production field detection.

Description

technical field [0001] The invention relates to a special measuring instrument with a meter for measuring the coaxiality between the installation position of the spline shaft parts (installation matching cylinder) and the spline ring gear, in particular to a meter with an assembled structure. Spline ring radial runout measuring instrument. Background technique [0002] In the automotive powertrain, transmission assembly, and steering assembly, it is very common for shaft parts to be connected and driven by splines. The installation and fixation of the spline shaft is generally through the cylinder and precision of one or several installation positions of the shaft. Therefore, the coaxiality error between the spline ring gear and the installation position cylinder directly affects the quality and life of the auto parts assembly. Due to the difference in the processing standards of the two (installation cylinders are generally positioned at the center hole for turning and gri...
