161 Gear Manufacture by Normal Machining
It is seen from Taniguchi s Table 11 that a gear is a mechanical product that is known for transmitting motion and power Various processes such as machining, casting, forging, cold-roll forming, extrusion, drawing thread rolling, powder metallurgy and blanking processes are usually employed to manufacture gears Non-metallic gears however can be made by injection moulding and casting Figure 16 depicts the standard nomenclature for an involute spur gear The dimensional accuracy and surface finish required for the proper functioning of gear teeth depend on the gear s intended use Poor gear-tooth quality leads to inefficient energy transmission and frictional and wear characteristics Although roll-formed gears can be made with an accuracy that is sufficient for most applications, for example, automotive transmissions, machining however remains an unsurpassed process for gear manufacture as this process can be used to make all types and sizes of gears to a very high accuracy

Gears are manufactured by machining either by form cutting or by generating processes with the latter producing gears with a better surface roughness and a greater dimensional accuracy Finishing processes such as gear shaving and grinding further improve the surface roughness and the accuracy of the tooth profile The cutting tool used in form cutting is similar to a form-milling cutter as regards the shape of the space between the gear teeth (Figure 17) Cutting the gear blank around its periphery reproduces the gear-tooth shape The cutter is fed radially towards the centre of the blank to obtain the desired tooth depth and is then moved across the tooth face to obtain the required tooth width After cutting

a tooth, the cutter is withdrawn, the gear blank is indexed (rotated), and the cutter is made to cut another tooth The process continues until all the teeth are cut Each cutter is designed to cut a wide range and a number of teeth The precision of the form-cut tooth profile depends on the accuracy of the cutter and the machine and its stiffness Conventional horizontal milling machines are normally used to form cut gears The basic principle that is utilized in form cutting is shown in Figure 17 Because the cutter has a fixed geometry, form cutting can be used only to produce gear teeth that have a constant width, such as in spur or helical gears but not to cut bevel gear teeth

In gear generation, the tool may be a (1) pinion-shaped cutter, (2) rack-shaped straight cutter, or a (3) hob The pinion-shaped cutter, being considered as one of the gears in a conjugate and the other as the gear blank, is used in gear generation on machines that are known as gear shapers (Figure 18) The axis of the cutter is parallel to that of the gear blank and rotates slowly with the blank at the same pitch-circle velocity with an axial reciprocating motion A train of gears provides the required relative motion between the cutter shaft and the gear-blank shaft After being generated, gears are normally shaved as is clearly shown in Figure 19 In the gear shaving process, a cutter, which is shaped exactly as the finished tooth profile, removes small amounts of material from the gear teeth The cutter teeth are slotted or gashed at several points along its width, and the motion of the cutter is such that it reciprocates It is recommended that shaving can
