Abstract
A gear machining device is provided which can machine an accurate gear by a cutting process by synchronously rotating a machining tool and a workpiece at a high speed. A machining tool includes roughing cutting teeth for roughing bottom lands and right and left side faces of teeth of a gear, right side face finishing cutting teeth for finishing the right side faces of the teeth, and left side face finishing cutting teeth for finishing the left side faces of the teeth. The cutting teeth thus cut different parts of the teeth of the gear. This can reduce cutting resistance and suppress self-vibration during the cutting process, thereby improving tooth trace accuracy of the gear.
Claims12
A gear machining device, comprising:
- a machining tool having a rotational axis tilted with respect to a rotational axis of a workpiece, wherein,
- the gear machining device machines a gear by relatively feeding the machining tool in a direction of the rotational axis of the workpiece while rotating the machining tool synchronously with the workpiece,
- the machining tool includes a rough cutting tooth, a right side face finishing cutting tooth, and a left side face finishing cutting tooth,
- the roughing cutting tooth roughly machines a bottom land, a right side face, and a left side face of the tooth of the gear,
- the right side face finishing cutting tooth finishes the right side face of the tooth of the gear, and
- the left side face finishing cutting tooth finishes the left side face of the tooth of the gear.
