The former moves the second gear axially or radially with respect to the first gear rotatably supported in advance in the gear case,
In response to the mutual interference between the teeth of the two gears during the movement process, the second gear is moved in a direction substantially perpendicular to the plane passing through the axes of the two gears, and the second gear is moved again. The second gear is moved in the axial direction or the radial direction, the second gear is engaged with the first gear, and the second gear is rotatably supported by the gear case.

The latter fixes a first gear that is rotatably supported on the GACOOSE in a non-rotatable manner, rotates the second gear while moving it in the axial direction, and meshes the second gear with the first gear. The second gear is rotatably supported on the gear case, and the fixed state of the first gear is released.

[Problem to be solved by the invention]

However, in the former method, the second ear is moved relative to the first gear, and the positions of the two gears are changed in response to mutual interference between the teeth of the two gears during the movement process. Since the second gear is then meshed with the first gear, when the teeth of the two gears interfere with each other, the @0 edge of one gear will not be on the tooth surface of the other gear. In addition, in the latter case, the second gear is rotated while moving in the axial direction and meshes with the fixed first gear. When the gears are engaged with the first gear, the edges of the teeth of one gear hit the tooth surfaces of the other gear, causing problems such as scratches in the * direction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for assembling gears in which the gears can be meshed and rotatably supported on a gear coosus so as not to damage the tooth surfaces.

In addition, in the above-mentioned measurement, the measurement targets are the pinion 4 and the gear 5, and the peaks and troughs of the measured voltage waveform also have curvature, but only two teeth are measured with the measurement reference position as the center. Therefore, the measurement difference due to the inclination of the teeth of the pinion 4 and the gear 5 due to the curvature of the circular arc does not pose a problem.

1. In addition, if a data table 16 is provided in the micro combinator 15 in which data such as the tooth width and pitch of the gears 5 and 4 to be geared are inputted, the above-mentioned binions 4 and gears 5 can be adjusted. When measuring, it is possible to have a check function that compares the measured data with the data in the data table 16 and, if the measured data differs by more than the allowable value, the assembly is canceled as a product is incorrect (5) Correction of the above calculation result i j X i to jX4
Among them, the one with the smallest correction amount is selected, and the second gear 5 is moved by a value corresponding to the correction amount in the direction perpendicular to the rotating shaft 42, that is, in the X-X direction. The positions of the teeth of the two gears 4 and 5 are aligned so that the teeth of the two gears 4 and 5 are aligned (see FIG. 6(a)).

(6) When the correction of ffi as described above is completed, the second gear 5 is moved along the 2-2 direction so that the first gear 20 is in a non-contact state with the pinion 4, that is, the second gear 5 is moved along the 2-2 direction. The pinion 4 and the second gear 5 are engaged with each other at a distance of about 0.5 mm from the regular center distance (see Fig. 6 (b).
).

From the above-mentioned state, the second gear 5 is moved as shown in FIG.
While maintaining the above-mentioned center distance between the binion 4 of the first gear 2 and the second gear 5, move it along the circular arc trajectory 1B with the center 01 of the binion 4, and the center 02 of the second gear 5 The second gear 5 is moved until it reaches the intersection 19 between the arcuate trajectory 18 and the assembly position t-line 2'2' parallel to the 2-2 direction.

Next, the second gear 5 described above is lowered in the z'-z' direction, and the rotating shaft 42 of the second gear 5 is rotatably supported on the gear case 1.

Here, the binion 4 of the first gear 2 described above is connected to the gear case 1.
Since the pinion 4 is rotatably supported by the shaft, the pinion 4 rotates with respect to the second gear 5 while the second gear 5 is moved on the arcuate track 1B in a non-contact state.

As described above, in the gear assembly method of the present invention,
The pinion 4 of the first gear 2 and the teeth of the second gear 5 come into contact with each other while the second gear 5 is moving on the arcuate track 18. During the movement, the above-mentioned contact between the teeth takes place. This contact between the teeth is a contact between the tooth surfaces (tooth surfaces), and there is no contact between the edges and the tooth surfaces, which is likely to damage the tooth surfaces. In addition, since the contact between the tooth surfaces is the same as in normal gear meshing, there is no damage to the tooth surfaces, and two gears can be meshed and rotatably supported on the gear case. .

Moreover, when moving the second gear 5 on the circular arc trajectory 18,
Since the pinion 4 of the first gear 2 and the second gear 5 are separated by about 0.5 mosiere from the normal center distance, even if there is some error in the above-mentioned arc trajectory 18, the distance between the two gears is There are no scratches on the tooth surface due to teeth squeezing together.

If steps (1) to (6) above are carried out in the same way, the %#E' gear 30 will mesh with the gear 3 of the first gear 2 and the gear case 1 will rotate to avoid scratching the tooth surface. Can be pivoted.

〔Effect of the invention〕

As is clear from the above, the gear assembly method of the present invention first determines the position of the second gear with respect to the first gear, then measures the tooth positions of the two positioned gears, and then Based on b, calculate the correction amount of the second gear O#io position for meshing the first gear and the second gear, and correct the position of the second gear by the correction amount of the calculation result.
Align the teeth of the second gear, then set the second gear to the first
The second gear is engaged with the gear in a non-contact state, and from that state the second gear is engaged with the first gear in contact with the II111, and the gear case is rotatably supported, so the @0 edge of one gear is connected to the other gear. The contact b1 is on the tooth surface of the gear.
The risk of scratching the tooth surface is extremely low. Therefore, the gears can be engaged and rotatably supported on the gear case so as not to damage the tooth surfaces.

The gear assembly device of the present invention also includes a holding and moving mechanism that holds the second gear and moves the ls2 gear in the direction of the rotational axis and in a direction perpendicular to the direction of the rotational axis, and a a position detection mechanism that detects a position, a measurement mechanism that measures tooth profiles of the positioned first gear and second gear, and meshes the first gear and the second gear based on measurements by the measurement mechanism. Said second for
A control mechanism is linked to a calculation mechanism that calculates the correction amount for the gear position, first determines the position of the second gear with respect to the first gear, then measures the positions of the teeth of the two positioned gears, and then Based on this measurement, a correction amount for the position of the teeth of the second gear is calculated, and the position of the second gear is corrected by the correction amount of the calculation result to align the positions of the teeth of the two ears.
Since the gear is meshed with the first gear and the second gear is rotatably supported by the gear case, the gear assembly method of the present invention can be carried out efficiently.
