摘要： A gear machining apparatus causes a machining tool and a workpiece to rotate at a high speed in synchronization with each other to machine a highly accurate gear through cutting. The machining tool is manufactured such that each of pitches between tool blades of the machining tool is an integer multiple of a pitch between teeth of the gear, the integer multiple being equal to or larger than double. By using the machining tool for cutting performed by the gear machining apparatus, the number of the tool blades of the machining tool, which are brought into contact with the workpiece at the same time, is reduced. Thus, it is possible to suppress occurrence of self-excited vibrations during cutting by reducing the cutting resistance. Thus, it is possible to enhance the tooth trace accuracy of the gear.

摘要： Gear-shaped precision-working tools, in particular shaving gears, capable of providing an optimum machining result only during a portion of their entire lifetime, since during each regrinding (generating), the profile displacement factor, and thus the number of the tooth flanks which engage successively and simultaneously one after the other the workpiece gear to be machined, is changed. This is remedied with the invention in such a manner that the precision-working tool is reground (generated) while maintaining the original number of teeth (z) and the original normal module of the pitch angle (.beta.), the module in transverse section and the base circle diameter are changed in such a manner that little or no change occurs to an original profile displacement factor (x). When the tool, which is to be reground (to be generated) in this manner, has grooved tooth flanks (12, 13), for grooves (14) increases continuously from a first groove (14') mutually adjacent one end of a tooth flank (12, 13) up to a second groove (14") mutually adjacent an other end of the same tooth flank, the grooves (14") having the greatest depth and the grooves (14') having the least on mutually adjacent and opposing tooth flanks (12, 13) opposing one another.

摘要： A laminated gear shaving tool formed by a stack of toothed discs mounted on a rotatable body. The flanks of each tooth are cut away to form lands, the lands being successively laterally displaced (staggered) across the disc thickness around the circumference. The cutting edges may be inclined across the tooth thickness and/or the lateral face may be re-entrant; the discs may be inclined to the axis of rotation of the tool; and, where the corresponding lands are not staggered, the toothed discs may be separated by spacing discs.

摘要： In a process for machining a spur gear by using a grinding worm having a curved tooth thickness smaller than the final measurement of the curved tooth gap of the spur gear to be produced, the grinding worm is first directed radially towards the spur gear until the desired distance between the axes is reached. Subsequently, a relative circular feed movement is carried out consisting of a positive or negative additional rotating movement of the gear or the worm. This additional rotating movement is superimposed on the corresponding basic revolution of the gear or the worm. In this way, first one flank and subsequently the other flank of each gear tooth is machined to its final dimension. With this process, a full linear contact exists between the grinding worm and the tooth flank of the gear during roughing independent of the amount of material to be machined. Due to the existing play, an effective cooling is possible so that high grinding outputs can be achieved.
摘要翻译：在通过使用具有小于要产生的正齿轮的弯曲齿隙的最终测量的弯曲齿厚度的研磨蜗杆来加工正齿轮的过程中，研磨蜗杆首先被径向朝向正齿轮定向，直到期望的达到轴之间的距离。随后，执行相对圆形进给运动，其包括齿轮或蜗杆的正或负的附加旋转运动。这个额外的旋转运动叠加在齿轮或蜗杆相应的基本转动上。以这种方式，每个齿轮齿的第一个侧面和随后的另一侧面被加工成其最终尺寸。通过这一过程，磨削蜗杆与齿轮的齿面之间完全线性接触，与加工材料的数量无关。由于现有的播放，有效的冷却是可能的，从而可以实现高磨削输出。

摘要： Helical gears adapted to mesh while rotated about parallel axes, are finished by meshing engagement with a shaving cutter gear rotated about an axis at a fixed cutting angle to the rotational axis of the helical gear being finished. A contact ratio close to but never less than one is established during meshing engagement between the helical gear being finished and the finishing gear by designing the helical gear teeth profiles within the limits of a contact ratio range applicable to meshing helical gears rotating about parallel axes.
