摘要： PURPOSE:To prevent waviness on the tooth face of a material to be rolled and the error in the tooth trance thereof by forming minor teeth between the leading teeth in each leading tooth group, and making the addendum of the minor teeth gradually lower from the beginning end side of the leading tooth group toward a finishing tooth group side. CONSTITUTION:Leading teeth 15 and minor teeth 16 in a leading tooth group 12 bite into a material 2 to be rolled in the beginning of rolling. Load fluctuates hardly and therefore waviness is not particularly generated during the time when rolling is accomplished by the group 12. The material 2 is further worked by a finishing tooth group 13 meshed therewith and the teeth already formed on the material 2 has roughly a specified shape. The working by the group 13 is accomplished mainly to correct the tooth profile without particular bite to the material 2 and the waviness in the tooth trance direction is not particularly generated on the tooth face of the material 2.
摘要翻译：目的：通过在每个前牙组中的前牙之间形成小齿来防止被卷绕材料的齿面上的波纹和牙齿恍惚的误差，并且从起始开始逐渐降低小齿的齿顶前牙组的端侧朝向精加工牙群侧。构成：在前轮齿组12中的前齿15和小齿16在轧制开始时咬入到待轧制材料2中。负载几乎不发生波动，因此在由组12完成轧制的时间期间不会特别产生波纹。材料2由与其啮合的精加工齿组13进一步加工，并且已经形成在材料2上的齿具有大致特定的形状。组13的工作主要是为了对材料2进行特别的咬合而矫正齿廓，并且在材料2的齿面上不特别产生牙齿恍惚方向上的波纹。

摘要： PURPOSE:To work a helical gear, etc. with good accuracy and to integrate processes by working the 1st working section of a work with a pair of rolling tools, grasping at the same time the adjacent 2nd working section with other tools and working the same. CONSTITUTION:A work 10 is grasped by respective flat dies 16, 17, and while a load P is exerted thereon, the upper dies 16, 17 and the lower dies 16, 17 are moved in the directions opposite from each other. The work 10 rotates and the tooth of the dies 16, 17 bit gradually into the 1st and 2nd working sections 12, 14. As a result, helical teeth 11 are formed in the 1st working section 12 and at the same time serration 13 is formed in the 2nd working section 14.

摘要： PURPOSE:To smooth the entire part of a tooth face and to decrease errors by forming a leading tooth group in such a way that the tooth thickness thereof is made to be thinner than the thickness of narrow-width finishing teeth. CONSTITUTION:Working tooth width (l) with respect to a material 2 to be rolled in the 2nd small group 14b is smaller than the tooth width W of the material 2 and the contact start end is inner by half of the pitch space in the transverse direction of a base body 11. The waviness acting on the tooth face of the material 2 by a narrow width finishing tooth is therefore the waviness deviated in phase by 1/2 from the waviness generated already on the tooth face. More specifically, the crest parts in the waviness generated in the tooth trance direction of the tooth face of the material 2 are crushed by the waviness generated when rolled by the narrow-width finishing teeth 16 after the 2nd small group 14b.
摘要翻译：目的：为了使牙齿的整个部分平滑，并且通过形成前牙组，使其齿厚比狭窄的精整齿的厚度更薄，从而减小误差。构成：相对于第二小组14b中被轧制材料2的工作齿宽（l）小于材料2的齿宽W，并且接触开始端在横向上位于间距空间的一半的内部因此，通过狭窄的精加工齿作用在材料2的齿面上的波纹是从已经在齿面上产生的波纹相位偏离1/2的波纹。更具体地说，在第二小组14b之后，在由材料2的齿面的牙齿龋齿方向产生的波纹中的波峰部分被由窄宽度精加工齿16轧制时产生的波纹破碎。

摘要： PURPOSE:To improve the thread rolling load and improve the precision by deviating the position of the finishing teeth part in the longitudinal and width directions. CONSTITUTION:The biting teeth part 1 and the roll off teeth part 3 of thread rolling flat dies 4a, 4b have the teeth width which is slightly larger than the working width B of a work W. On the other hand, the finishing teeth part 2 is formed by a narrow teeth part 22 having the teeth width Sa, Sb which is approximately half of the working width B, and the number of the teeth including at least the rolling length for half rotation of the work W is defined as one teeth group, and the positions of the respective teeth groups are deviated in the longitudinal and width directions. The thread rolling load on the finishing teeth part 2 becomes approximately half of that for the full width thread rolling, and the strains generated in the sliders 13a, 13b, the respective columns 12a, 12b, and the tie-bar 10 in the thread rolling equipment are greatly reduced, and the desired pitch precision is secured.

摘要： PURPOSE:To obtain a rolled product having good finish accuracy by setting the contact start end of a round die having a narrow set tooth width with a material to be rolled on the side inner than that of the other round die in the axial line direction of the material. CONSTITUTION:The tooth width L with one round die 10 is wider than the tooth width W of a material 3 to be rolled and therefore the die starts to mesh with a material to be rolled from the end thereof in the axial line direction of said material. The other round die 11 and the material 3 to be rolled start meshing with each other on the side inner than the end thereof in the axial line direction of the material 3. The waviness arising from the fluctuation in the number of the meshing teeth and the meshing point resulted from meshing of the other round die 11 with the material 3 is the waviness deviated by 1/2 in phase. The crest parts in the waviness generated in the tooth trance direction on the tooth surface of the material 3 are therefore successively crushed, by which the error of the tooth trance on the tooth surface is corrected and the accuracy is improved.
摘要翻译：目的：为了获得具有良好精加工精度的轧制品，通过将具有窄的设定齿宽度的圆形模具的接触开始端设置在与其他圆形模具的内侧相比在轴线方向上的待轧材料的侧面上材料。构成：具有一个圆形模具10的齿宽L比待轧制材料3的齿宽W宽，因此模具从所述材料的轴线方向从其端部开始与待轧制的材料啮合。另一个圆形模具11和待轧制材料3在材料3的轴线方向上的内侧比其端部的内侧彼此啮合。由于啮合齿的数量的波动和另一个圆形模具11与材料3的啮合产生的啮合点是相位偏差1/2的波纹度。因此，在材料3的牙齿表面上的牙齿恍惚方向产生的波纹中的波峰部分因此被连续地压碎，由此校正牙齿上的牙齿恍惚的误差并提高精度。

摘要： PURPOSE:To perform rolling with good accuracy with decreased errors of a tooth trance by making different the phases of the waviness by the 1st flat die of a pair of flat dies and the waviness by the 2nd flat die. CONSTITUTION:The tooth width L in the 1st flat die 10 is wider than the tooth width W of a material 2 to be rolled and therefore the die starts to mesh with the material 2 from the end part thereof. The tooth width (l) of the 2nd flat die 20 is narrower than the tooth width W of the material 2 and the space between the end of the working tooth width (l) thereof and the end of the material 2 is set at half the pitch space and therefore the 2nd die 20 starts to mesh with the material 2 on the side inner than the end of the material 2. As a result the waviness arising from the fluctuation in the number of intermeshing teeth and the intermeshing point to be resulted from the meshing of the 2nd die 20 with the material 2 deviates by 1/2 in phase from the waviness by the 1st die 10. The crest and troughes of each waviness by the dies 10, 20 are thus reversed from each other, by which the crest parts of the waviness are gradually crushed and the errors in the tooth trance of the tooth face are corrected. The accuracy is thereby improved.
摘要翻译：目的：通过使一对扁平模具的第一平模和第二平面模具的波纹形成波纹的不同阶段，以良好的精度进行滚动，减少牙齿恍惚的误差。构成：第一平模10中的齿宽L比待轧制材料2的齿宽W宽，因此模具从其端部开始与材料2啮合。第二平模20的齿宽（l）比材料2的齿宽W窄，其工作齿宽（l）的端部与材料2的端部之间的空间设定为因此第二模具20开始与材料2的内侧相比材料2的端部网格化。结果是由于相互啮合的齿数和相互啮合点的波动而产生的波纹是由第二模具20与材料2的啮合与第一模具10的波纹相位偏离1/2的相位。因此，模具10,20的每个波纹的波峰和间隙因此相互反转，由此波纹的波峰部分逐渐粉碎，牙齿牙齿恍惚的误差得到纠正。从而提高精度。
