GB/T 26093-2010Gear dual-flank meshing measuring instrument (English PDF)

3.1 Gear dual-flank meshing measuring instrument

A measuring instrument of which the gear to be tested and the measuring gear are meshed on both sides without gap, and the change of the meshing center distance is measured by using an indicator measuring instrument or a displacement sensor to measure the radial comprehensive error of the gear, the radial comprehensive error of one tooth, the radial runout of the gear ring, etc. The use of corresponding optional accessories can also realize the measurement of gear tooth thickness deviation, gear pair side clearance and center distance deviation, worm gear radial comprehensive error, and bevel gear axial spacing variation.

4.1 Types

The basic type of the dual-flank meshing instrument is shown in Figure 1. The optional accessories are shown in Figure 2. The figure is for illustration only and does not show the detailed structure.

5.4 Straightness

The straightness of the main carriage movement shall not be greater than 10".

5.5 Wobble

The wobble of the main carriage movement shall not exceed 15".

5.6 Parallelism

5.6.1 The parallelism of the main carriage spindle axis and the measuring carriage spindle axis in both the longitudinal and transverse directions shall not be greater than 5 µm over a length of 50 mm.

5.6.2 The parallelism between the line connecting the upper and lower centers of the column and the axis of the measuring carriage spindle in both the longitudinal and transverse directions shall not be greater than 5 µm over a length of 50 mm.

5.6.3 The parallelism between the vertical and horizontal directions of the horizontal frame and the axis of the measuring slide shaft shall not be greater than 5 µm over a length of 50 mm.

5.6.4 The parallelism between the axis of the cross-frame spindle and the end face of the measuring slide rotating sleeve shall not be greater than 5 µm over a length of 50 mm.

5.6.5 The parallelism of the end face of the measuring slide rotating sleeve of the two center points on the cross frame shall not be greater than 10 µm over a length of 50 mm.

5.7 Circular runout

5.7.1 The radial runout and end face runout of the rotating sleeve shall not be greater than 3 µm.

5.7.2 The oblique circular runout of the main center of the cross frame shall not be greater than 5 µm.

5.8 Measuring force

The measuring force of the dual-flank meshing instrument shall not exceed 22 N.

5.9 Indication variability

The indication variability of the dual-flank meshing instrument shall not be greater than that specified in Table 2.

5.10 Indication error

The indication error of the dual-flank meshing instrument shall not be greater than that
