A gear shaper is a metal cutting machine tool used to process gears. Here are 10 knowledge points about gear shaper:
1. Definition: A gear shaping machine is a gear processing machine tool that uses a gear shaping cutter to process internal and external spur and helical gears and other gear parts according to the method of generation.
2. Working principle: The gear shaping machine processes gears according to the principle of generation method through the up and down reciprocating cutting motion of the gear shaping cutter and the relative rolling with the workpiece.
3. Processing capacity: Gear shaping machine is mainly used to process multi-link gears and internal gears. It can also treat racks with the appropriate accessories.
4. Clamp design: The clamp design of the gear shaping machine should take into account the study of the height direction, including factors such as the extension length of the cutting shaft, the length of the cutting rod and the height of the column.
5. Precision requirements: During the gear shaping process, the cumulative deviation of the workpiece tooth pitch is generally larger than that of the hobbing, which may affect the precision of the final product.
6. Tool selection: There are many types of gear shaping cutters, including disc-shaped, bowl-shaped, tapered handle, cylindrical, etc.
7. Module pressure angle: When selecting a gear shaping cutter, you should ensure that the module and pressure angle of the gear shaping cutter match the module and angle of pressure of the gear being processed.
8. Processing methods: The gear shaping machine can carry out different processing methods such as high circumferential feeding to adapt to various production needs.
9. Load control: Modern gear shaping machines are often equipped with the function of controlling the cutting feed speed according to the load to improve processing efficiency and protect tools.
10. Widely used: As an important method of tooth profile processing, gear shaping is often mentioned together with gear hobbing and is widely used in the field of gear manufacturing.
