Description

本発明は、歯車を加工するために用いる歯切工具であるスカイビングカッタに関する。   The present invention relates to a skiving cutter which is a gear cutting tool used for machining a gear.

従来よりピニオンカッタやスカイビングカッタに代表される歯切工具を用いた被削物（ワーク）の加工では、被削材である歯車を構成する歯部の先端に面取り加工を施す場合があった。その場合には、歯切工具の歯底付近に面取りを施す専用の刃部が設けられている。   Conventionally, in the processing of a workpiece (work) using a gear cutting tool represented by a pinion cutter or a skiving cutter, there is a case where chamfering is performed on the tip of a tooth portion constituting a gear which is a workpiece. . In that case, a dedicated blade portion for chamfering is provided near the bottom of the gear cutting tool.

例えば、特許文献１ないし３には歯先と歯底の間に傾斜した刃部（面取り専用刃部）を備えたピニオンカッタが開示されている。この様な歯切工具を使用することで、被削材の内周側に歯車を加工すると同時に、その歯車の歯部の先端に面取り加工を施すことができる。   For example, Patent Documents 1 to 3 disclose a pinion cutter having a blade portion (a chamfering blade portion) inclined between a tooth tip and a tooth bottom. By using such a gear cutting tool, it is possible to chamfer the tip of the tooth portion of the gear at the same time as processing the gear on the inner peripheral side of the work material.

しかし、面取り加工を行う刃部を用いて被削材の歯車を加工した時、被削材の歯部の縁にバリが発生するという問題があった。被削材の歯部の縁にバリが発生すると、歯切工具による歯車加工の後に、別の工具（例えば、専用のバリ取り工具）を用いてそのバリを除去する必要があり、歯車製作工程において新たな工程が加わることになる。   However, when the gear of the work material is machined using a blade portion that performs chamfering, there is a problem that burrs are generated at the edge of the tooth portion of the work material. If burrs occur at the edges of the teeth of the work material, it is necessary to remove the burrs using another tool (for example, a dedicated deburring tool) after the gear cutting with the gear cutting tool, and the gear manufacturing process A new process will be added.

そこで、本発明においては歯車加工時において被削材の歯部に面取り加工を行うと同時に、面取り加工により発生するバリも除去できるスカイビングカッタを提供することを課題とする。   Therefore, an object of the present invention is to provide a skiving cutter that can chamfer the tooth portion of the work material during gear machining and at the same time remove burrs generated by the chamfering.

前述した課題を解決するために、本発明は歯車型の歯面に複数の切刃を備えるスカイビングカッタにおいて、切刃と歯底の間には面取り用の刃部を有して、かつ歯底には段差部を設けるスカイビングカッタとした。また、この段差部は、歯先と平行である第１平行部および第２平行部の間に設けることもできる。 In order to solve the above-mentioned problems, the present invention provides a skiving cutter having a plurality of cutting blades on a gear-type tooth surface, having a chamfering blade portion between the cutting blade and the tooth bottom, and a tooth. A skiving cutter with a stepped portion at the bottom was used. Moreover, this level | step-difference part can also be provided between the 1st parallel part and 2nd parallel part which are parallel to a tooth tip.

本発明のスカイビングカッタを用いることで、歯車加工時において被削材の歯部に面取り加工を行うと同時に、面取り加工により発生するバリも除去できるという効果を奏する。 By using the skiving cutter of the present invention, it is possible to remove the burrs generated by chamfering at the same time as chamfering is performed on the teeth of the work material during gear machining.

本発明の一実施形態を示すスカイビングカッタ１の歯先３および歯底４における拡大斜視図である。It is an expansion perspective view in the tooth tip 3 and the tooth base 4 of the skiving cutter 1 which shows one Embodiment of this invention.

本発明のスカイビングカッタの形態について図面を用いて説明する。本発明の一実施形態を示すスカイビングカッタ１の歯先３および歯底４における拡大斜視図を図１に示す。本発明のスカイビングカッタ１は図１に示すように歯車型の歯面に互いに隣接する複数の切刃２、２を備えている。   The form of the skiving cutter of this invention is demonstrated using drawing. An enlarged perspective view of the tooth tip 3 and the tooth bottom 4 of the skiving cutter 1 showing an embodiment of the present invention is shown in FIG. As shown in FIG. 1, the skiving cutter 1 of the present invention includes a plurality of cutting blades 2 and 2 adjacent to each other on a gear-type tooth surface.

このスカイビングカッタ１を形成する切刃２と歯底４との間には、図１に示すように面取り用の刃部１０が設けられている。また、歯底４には溝部１００が形成されることで左右両側に段差部２０、２１が設けられている。この段差部２０は、溝部１００の底面と歯底４を形成している第１平行部３０との高さ（深さ）の差異でもある。同様に、段差２１は溝部１００の底面と歯底４を形成している第２平行部４０との高さ（深さ）の差異となる。 A chamfering blade 10 is provided between the cutting blade 2 and the tooth bottom 4 forming the skiving cutter 1 as shown in FIG. Moreover, the groove part 100 is formed in the tooth base 4, and the level | step-difference parts 20 and 21 are provided in both right and left sides. The step portion 20 is also a difference in height (depth) between the bottom surface of the groove portion 100 and the first parallel portion 30 forming the tooth bottom 4. Similarly, the step 21 is a difference in height (depth) between the bottom surface of the groove portion 100 and the second parallel portion 40 forming the tooth bottom 4.

つまり、これらの第１平行部３０および第２平行部４０は、それぞれ溝部１００が形成される前に歯底４を形成していた一部分であり、歯底４の面はスカイビングカッタ１の歯先３と平行になるように形成されている。図１では、第１平行部３０および第２平行部４０は共にほぼ同じ位置（高さ）となるように形成されているが、第１および第２平行部３０、４０の位置は異なっていても構わない。 That is, each of the first parallel portion 30 and the second parallel portion 40 is a portion that formed the tooth bottom 4 before the groove portion 100 is formed, and the surface of the tooth bottom 4 is the tooth of the skiving cutter 1. It is formed so as to be parallel to the tip 3. In FIG. 1, both the first parallel part 30 and the second parallel part 40 are formed to have substantially the same position (height), but the positions of the first and second parallel parts 30 and 40 are different. It doesn't matter.

また、段差部２０、２１の大きさ（幅や深さ）は歯底４に形成される溝部１００の大きさ（幅や深さ）によって任意に調整できるものとする。 In addition, the size (width and depth) of the stepped portions 20 and 21 can be arbitrarily adjusted by the size (width and depth) of the groove portion 100 formed in the tooth bottom 4.
