Systematic classifications of gearcutting machines can be made from a variety of different standpoints. As a general survey, all techniques for the production of gear wheels are summarized in Fig. . From the aspect of the qualities obtainable, differentiation may be made between roughing and finefinishing processes. In line with the previous chapters, the techniques will be divided into chipproducing and chipless production methods. The chipproducing machines are further subdivided according to the cutting geometry of their cutting tools. In order to achieve an economic production rate, whilst at the same time maintaining a high degree of accuracy of the gears produced, gear cutting is menced with a high cutting speed and fast feed rates. This is then followed with a finishing process. For rough gear cutting, the processes most widely used are those of hobbing, gear shaping and for larger gear wheels, gear planing。).A further subdivision of gearcutting machines may be made in accordance with the type of gear which may be produced on them, which will be discussed in the following sections. The various forms of gears illustrated in Fig. are classified in accordance with the relative position of the axes of rotation of mating gears and require specific gearcutting machines to produce them gears (parallel axes of rotation and rolling action) can have external as well as internal teeth, and these may be straight, helical or doublehelical in gears can have their teeth straight, helical or curved. In the latter ease the lines of the flanks of the teeth may basically follow as involutes or an epicycloids. (The Czechos has a prehensive term “ kot225。 the work table, which is mounted on the gene rating slide, provides the rotary generating motion by obtaining its drive from the indexchange gear train (7), transmitted to a telescopic shaft and on to a worm and worm wheel drive. The remaining auxiliary drives are used to set the root circle radius with a motor or a handwheel (26), for activation of the radial depth of cut movement using the gear train (27) and the bed spindle (11), and for the backlashfree engagement of the reversing movement (12, 16 and 18), when the gene rating slide has reached the end of its . Drive layout of a gearplaning machineA schematic diagram of the machine construction is given in Fig. . The column with the tool slide (angularly adjustable for helical teeth) is bolted to the machine bed. The rotating work table lies on a coordinate slide which is used for the radial cutting depth infeed and the tangential gene rating action. On large machines, the radial cutting depth in feed is provided by a sliding column. Figure shows a front view of a gearplaning machine. Bevel gears The production of bevel gears has some similarities with the manufacture of spur gears. In place of the rackformed cutting tool, the cutter takes the form of a face gear, the principle of which is shown in Fig. . As a result of the generating motion between the face gear (cutting wheel with a straight sided, racktype profile) and the gear blank inclined at the bevel angle δ, the geartooth flanks are produced. The cutting motion is in the direction of the length of the machines, for straight and helical teeth, work on the indexinggenerating principle. Their drive mechanism is similar to that of spurgear planing machines. Instead of the linear movement of the cutting rack, the cutting drum turns, so rotating the planing tool (face gear), and thus producing its cutting motion. Figure illustrates such a bevelgearplaning method of bevelgear planing which must be defined as a bevelgear formplaning process is the template technique. The cutting tool is guided by a template to produce the desired tooth profile. The method is used for the 39。ShearSpeed blades39。 the actual profile takes shape only just before the end of a single cut. This can, under certain circumstances, lead to quality problems as a result of 39。shifting39。 the gene rating process then mences. The cone of the gear blank thus rolls against the gene rating plane. Each tooth space is pleted in a single cut, and when finished the work is indexed. For the cutting of modules of m 7 mm, two operations are carried out。 the cutting action occurs about the cutter head axis (4). The plunge movement is obtained through the movement of the slide (8).
