Tooth milling cutter and method for milling the teeth of toothed gear elements

The present invention relates to a method for milling a series of teeth (2, 13) of a toothed gear element with teeth in a straight line, comprising a milling cutter (10), which is rotatable about a milling cutter axis (21) and has at its periphery interchangeable cutting inserts (5), which are arranged in such a way that, when the milling cutter (10) is brought up to the toothed gear element, they reach into the gaps (16) between adjacent teeth (12, 13) or generate these gaps, and relates to a corresponding milling cutter. In order to provide a method for milling teeth of a toothed gear element with the aforementioned features, which along with high productivity also allows a very exact tooth profile form without faceting, and with which even relatively complex teeth profiles can be generated without changing or readjusting the cutting inserts that are mounted on the milling cutter, it is proposed according to the invention to use a milling cutter on which the cutting inserts have in the state in which they are mounted on the milling cutter at least one cutting edge (8a, b) extending radially and perpendicularly in relation to the milling cutter axis, wherein, during the milling of the tooth profile, the milling cutter axis is aligned in a plane perpendicular to the longitudinal extent of the back of the tooth and, during the entering of the cutting inserts (5), rotating about the milling cutter axis, into the surface or gaps between the teeth of a toothed gear element, is pivoted in this plane over an angular range that covers the range of all the normals to the profile surface (12a,b; 13a,b) of the tooth (12, 13) to be produced.

Semi-completing skiving method and device having corresponding skiving tool for executing a semi-completing skiving method

기어 이빨의 제조 중에 두 측면이 서로 다른 설정을 이용하지만 교번의 세미 컴플리팅 스카이빙 방법의 응용과 함께 지속적으로 동일한 공구(100)를 이용하여 스카이빙된다는 점이 이 발명의 방법에 대한 특징이다. 예를 들어 공구(100)의 모든 왼쪽 측면 절삭 에지가 2회 사용되는 반면에 오른쪽 측면 절삭 에지는 1회만 사용되는 것이 세미 컴플리팅 접근 방식의 본질이다. 본 발명에 따르면, 이전에 제1 공작물(50.1)의 가공 중에 더 강한 부하를 받았던 측면 절삭 에지가 이제 다음의 스텝에서 덜 빈번하게 사용되도록 기어 이빨을 제조하기 위해 동일한 공구(100)가 사용된다. 이것은, 다른 측면 절삭 에지가 제2 공작물(50.2)의 제조 중에 더 강하게 또는 더 빈번하게 사용되도록 함으로써 달성된다. It is a feature of the method of the present invention that during fabrication of the gear teeth, the two sides are using different settings, but are continuously smoothed using the same tool 100 with the application of the alternate semi-complicated skiving method. For example, all the left side cutting edges of the tool 100 are used twice, whereas the right side cutting edge is used only once is the essence of the semi-completing approach. According to the present invention, the same tool 100 is used to manufacture the gear teeth such that the side cutting edge, which had previously been subjected to a heavier load during the machining of the first workpiece 50.1, is now used less frequently in the next step. This is achieved by allowing the other side cutting edge to be used more strongly or more frequently during the manufacture of the second workpiece 50.2.

Tooth milling cutter and method for milling the teeth of toothed gear elements

The present invention relates to a method for milling a series of teeth (2, 13) of a toothed gear element with teeth in a straight line, comprising a milling cutter (10), which is rotatable about a milling cutter axis (21) and has at its periphery interchangeable cutting inserts (5), which are arranged in such a way that, when the milling cutter (10) is brought up to the toothed gear element, they reach into the gaps (16) between adjacent teeth (12, 13) or generate these gaps, and relates to a corresponding milling cutter. In order to provide a method for milling teeth of a toothed gear element with the aforementioned features, which along with high productivity also allows a very exact tooth profile form without faceting, and with which even relatively complex teeth profiles can be generated without changing or readjusting the cutting inserts that are mounted on the milling cutter, it is proposed according to the invention to use a milling cutter on which the cutting inserts have in the state in which they are mounted on the milling cutter at least one cutting edge (8a, b) extending radially and perpendicularly in relation to the milling cutter axis, wherein, during the milling of the tooth profile, the milling cutter axis is aligned in a plane perpendicular to the longitudinal extent of the back of the tooth and, during the entering of the cutting inserts (5), rotating about the milling cutter axis, into the surface or gaps between the teeth of a toothed gear element, is pivoted in this plane over an angular range that covers the range of all the normals to the profile surface (12a,b; 13a,b) of the tooth (12, 13) to be produced.

Smilled spline apparatus and smilling process for manufacturing the smilled spline apparatus

By combining shaping and milling actions, or smilling, the cutting tool can move through the entire usable portion of the spline and machine a tool relief into the face of the adjacent feature such as a shoulder before retracting, reversing direction, and repeating the cycle. The smilling apparatus and manufacturing method eliminates the need for an annular spline relief and the full length of spline engagement can be utilized for strength. The effective width of the spline connection apparatus manufactured by the smilling process conserves space and increases the load carrying capability of the spline connection.
