Explain the structural principles of gear machining in detail

For example, uneven tooth pitch can affect transmission efficiency and accuracy. Uneven tooth roots can easily cause other gears to collapse; Uneven gear tooth height can easily cause tooth collapse; Irregular gear size can cause the centerline of the gear to be uncorrected, and the load cannot be corrected. Evenly distributed on the contact surface of teeth, such as wear or scratch, wear, pitting, plastic deformation, etc. Therefore, it is necessary to measure the relevant parameters of the gear and then process the gear to meet high precision applications.
In gear processing, there are many different machining machines that produce different gears. Next, let's take a look.
The gear hobbing machine uses a hob to perform rough and precision machining on straight teeth, helical gears, herringbone gears, and worm gears based on the generation method. Wide processing range, capable of achieving high precision or productivity; The gear forming machine uses the production method of the gear forming machine to process spur gears, helical gears, and other tooth shaped parts, mainly used for processing multiple gears and internal gears; Gear milling machines are processed using indexing method and forming milling cutters, mainly used for processing instrument gears with special tooth shapes; Gear shaving machine This machine is an efficient machine tool that uses a gear type shaver to complete the machining of gears. Gear grinding machine is a high-precision machine tool that uses grinding wheels to finish machining hardened cylindrical gears or gear cutting surfaces; The honing machine uses honing wheels for free meshing of gears, which can eliminate hardened gear burrs and other tooth surface defects. The gear extruder adopts a high hardness extruder without a blade, which engages freely with the workpiece and grinds the surface unevenness of the teeth, improving accuracy. Gear chamfering machine is a machine tool that circulates the tooth ends of sliding gears that mesh internally and externally, and is an essential processing equipment for producing gearboxes and other speed changing mechanisms. The cylindrical gear processing machine tool also includes a gear hot rolling machine and a gear cold rolling machine.
The bevel gear processing machine tool is mainly used to process the teeth of bevel gears, such as straight teeth, helical teeth, helical teeth and Epicycloid teeth.
Straight bevel gear planer is a machine tool that uses a pair of gear planers to perform rough and fine machining on straight bevel gears based on the generation method. Some machine tools can also plan helical gears, which are widely used in small and medium-sized batch production.
