本発明は通常のホブを用いて歯車の歯先の面取
りを行なう方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for chamfering the tips of gear teeth using a conventional hob.
近年、自動車あるいはオートバイ等の動力伝達
装置に用いられる歯車は、強度上あるいは騒音減
少の面からその歯先を面取り加工されていること
が多い。このように処理された歯車を第１図に示
す。図中、Ｘで示した部分が面取りである。 In recent years, gears used in power transmission devices such as automobiles and motorcycles often have their tooth tips chamfered for reasons of strength or noise reduction. A gear treated in this manner is shown in FIG. In the figure, the portion indicated by X is chamfered.
従来、このように歯車の面取りを行なうには、
特殊な形状をなしたホブ（セミトツピングホブ）
を用いて加工するのが一般的である。しかしなが
ら、歯車の面取り形状は個々の歯車それぞれに異
なつているため、その形状に対応したホブを準備
しておかねばならず、工具管理上好ましくない。 Conventionally, to chamfer gears in this way,
A hob with a special shape (semi-topping hob)
It is common to process using However, since the chamfered shape of each gear is different for each gear, a hob corresponding to the shape must be prepared, which is not preferable in terms of tool management.

て再び歯切り加工することを特徴とする。 In view of the above-mentioned circumstances, it is an object of the present invention to provide a gear cutting process that can chamfer the tooth tip of a gear using an ordinary hob without using a special hob. , the gear cutting process is performed again using the hob while changing the mounting angle of the hob by a predetermined amount.

すれば面取りができるものである。 Embodiments according to the present invention will be described below based on the drawings. FIG. 2 is an explanatory diagram showing normal gear cutting, and FIG. 3 is an explanatory diagram showing a chamfering state. Second
In the figure, the hob cutter 1 is attached to a hobbing machine (not shown) at a predetermined mounting angle T°, as shown in A of the figure, to carry out normal hobbing. The cutting surface of the hob cutter 1 at that time, that is, the cross section perpendicular to the axis of the gear to be machined is shown in FIG.
Figure C is an enlarged view. After completing the hobbing process in this state, operate the hob head of the hobbing machine (not shown) to further adjust the 1st axis of the hob cutter by α°.
The tip of the gear to be machined can be chamfered by tilting it by (or -α°) and machining at a predetermined distance from the gear to be machined. In addition,
The cutting edge of the hob cutter is designed based on the hob specifications, so the mounting angle T° of the hob cutter must be set correctly according to the helix angle of the gear being machined as the hob cutter advances. Next, by tilting the hob cutter by ±α°, the blade shape of the hob cutter becomes larger when viewed from the side of the gear to be machined. Therefore, in this state, chamfering can be achieved by increasing the distance between the hob cutter and the gear to be machined, that is, by making the cut shallower.

理の面においても有効である。 As explained above, according to the present invention, after the normal hobbing process using a hobbing machine is completed, chamfering can be performed by changing the mounting angle of the hob cutter and keeping the hob cutter and the gear to be machined separated by a predetermined distance. This method is also effective in terms of tool management, since there is no need to prepare a hob cutter for chamfering, and there is no need to prepare a variety of hob cutters depending on the shape of the chamfer.
