6OP70 shaving, the test process diagram is shown in Figure 7. The main test items are as follows:

The ring gear radial runout 4: 0. 04 mm, the detection method is to use a special gage, observe each measured value, at least measure the maximum reading of three equally spaced teeth: 0. 04 mm.

The average distance between the bottom of the steel ball and the center of the tooth 5: the sum of the detected values ​​divided by the number of tests = Ex(+9) + (+7) + (+5) /3

The accuracy of the gear is checked on the M&M gear measuring center. When measuring, the gear taper face down and the clamping can be positioned with the expandable mandrel. The parameters input during the programming measurement are the left direction, the left tooth surface is the working surface, the right tooth surface is the non-working surface, the minimum tooth width is 15.4 mm, and the maximum value of the chamfer is 2 mm.

Maximum tooth direction error f _{H β} : right flank: (5 ± 4) mm; left flank: ( 5 ± 4) mm.

Maximum tooth direction drum amount error f C _β : Right flank: ( 6 ± 3) mm; Left flank: ( 6 ± 3) mm.

Maximum tooth profile direction error f _{H α} : Right flank: ( -12 ±7) mm; Left flank: ( -12 ±7) mm.

Maximum tooth shape drum error f C _α : Right flank: ( 4 ± 4) mm; Left flank: ( 4 ± 4) mm.

Maximum tooth direction direction error variation Wf _{H β} : left flank: 10 mm; right flank: 10 mm.

Maximum tooth shape direction error variation Wf _{H α} : Right tooth surface: 10 mm; Left tooth surface: 10 mm.

Tooth shape error ff _α : right flank: 7 mm; left flank: 7 mm.

Tooth shape shape error ff _β : right flank: 6 mm; left flank: 6 mm.

The average adjacent pitch error f _um : 6mm. Pitch cumulative error Fp: 58mm.

7OP140 honing the inner hole, the test process diagram is shown in Figure 8, mainly to detect the following three items, 12, 13, 15, 12, 13

Two items were measured on the yaw meter and 15 items were measured on the three coordinates.

8毫米。 The 8OP150 grinding cone surface and end face, the detection process diagram is shown in Figure 9, the main test is as follows: straightness of 0. 01 mm; coaxiality Φ0. 03 mm; roundness of 0. 02 mm; The straightness and roundness are measured on the roundness, and the coaxiality and the circular run are measured on the three-coordinate measurement.
