Detailed explanation of gear processing equipment and process methods

Gear processing equipment is used for metal cutting in gear processing. The gear processing device has a closed frame structure to increase the stiffness and precision of the gear processing device. The gear processing device includes a base, a cylindrical structure, a linear moving device, a second linear moving device, a rotating workbench, and a third linear moving device. Among them, both cylindrical structures and linear moving devices have closed frame structures to reduce overall weight and increase resonance frequency. The gear processing device uses a symmetrical linear motor to drive the linear movement device, and a direct drive motor to drive the spindle head and turntable.
Gear processing technology belongs to the field of mechanical manufacturing. The tooth tip reference circle formed during the machining process provides a reliable alternative reference for positioning and clamping during hot post processing. This makes the positioning and clamping of the workpiece reliable and easy to clamp, resulting in higher and more stable quality of the gear. Compared with the original clamping method, firstly, it significantly enhances the ability to overcome reciprocating axial forces, reduces the impact of grinding wheel powder on the machining quality during the positioning and clamping process, and completely eliminates the problem of full wheel rotation. Tooth pitch circle fixture. The wear and deformation of drum shaped cylinders have an impact on the related machining quality, making the gear machining quality stable. The second is the decrease in scrap rate, the increase in workpiece clamping speed, and the cost savings of full pitch circular fixtures, resulting in a corresponding reduction in gear manufacturing costs.
Gear machining methods include forming methods and generating methods. The forming method is to directly use a gear forming milling cutter to mill out tooth valleys. The advantage is that gears can be obtained on the milling machine, which can be considered when the equipment is limited. There are many drawbacks. In order to reduce the number of tools, the number of teeth is segmented and a knife is used within a portion of the number of teeth, resulting in systematic errors in gears. The generation method uses tools and gears to generate motion for machining gears. There are mainly gear hobbing and gear forming. Machining gear hobbing by simulating the meshing of worm gears. Gear forming is carried out by simulating the meshing of two gears. Hobbing is often used because the tooth profile of the hobbing cutter is straight and easy to machine, while the gear forming tool is a gear with a backhoe, and the gear is involute, making machining less convenient.
