の方が小さくなる。In the rolling finish processing of gears, when the gear rolling die (1) rotates clockwise and the gear to be processed (2) rotates counterclockwise in Figure ii, the right tooth surface on the center of the gear (2), that is, the driven f111 ( The slip that occurs on the tooth surface of 4) and the left tooth surface, that is, the tooth surface on the follower side (5), is from the pitch point on the driven side (4) as a boundary, from the tooth tip to the pitch point, and from the splintered tooth root to the pitch point. It appears like an arrow towards the follower side (5
) on the tooth surface, on the other hand, the pitch point is the boundary,
Occurs from the pitch point to the tooth tip, from the pitch point to the tooth root,
At the same time, a flow of material occurs in the same direction as the alignment. (6)
Figure 2 shows the meshing pitch circle. By the way, the tooth profile of pre-machining tools such as conventional hobs and pinion cutters is symmetrical, so the tooth profile of both flanks of the pre-machined workpiece gear is shown in Figure 2 (I). ), the area is increased symmetrically as v view F
are equal. When such a workpiece gear is rolled and finished, the amount of chamfering on the left and right sides will differ due to the difference in the flow direction of the material, as shown in Figure 2 (middle), and the amount of chamfering on the driven side (Fl ) Chamfering amount on the follower side (F″)
is smaller.

うとするものである。The purpose of the present invention is to solve the problems associated with such conventional gear rolling processing methods.
In order to make the gear tooth profile before machining asymmetrical, the left and right tooth profile shapes of a gear gear cutting tool used as a pre-processing tool are asymmetrical, and the symmetry of the left and right tooth flank shapes of the workpiece gear after rolling is improved. It is.

ある。According to the present invention, as mentioned above, the amount of chamfering after rolling is smaller on the follower side (5) than on the driven side (4), so the pre-processing f' is performed in advance as shown in FIG. 3(A). The amount of chamfering on the follower side (5) of the gear to be machined (2) (F2) and the amount of chamfering on the entire driven side (4) (F+) As shown in FIG. The height He from the tooth tip of the cutting edge (9) corresponding to the tooth surface on the side (4) is made smaller so that the amount of chamfering of the gear due to pre-machining is increased.

To manufacture a standard gear (tooth depth 2.35 m = 4.7), cut the follower side of the pre-processing hob (7) with the standard rack tooth profile as shown in Figure 4 ('r). Height of cutting blade (8)) is2f 4.270 cm,
The cutting edge (9) that cuts the driven side has a length l-1s of 4.391 crn, which is smaller than the former. Driven side (4) of gear to be machined (2) pre-machined with this tool
Chamfer amount (F+) is 0.17 cm, follower'
