2Machining methods of large cylindrical gears: Fan Cheng method and forming method

2Machining methods of large cylindrical gear tooth profile: Fan Cheng method and forming method, their specific instructions are as follows, for reference.

XNUMX. Fan Chengfa

It’s also called the spreading method, and it’s made by this method.Gear processingHigh precision, it is a method of cutting out the gear tooth profile by using the meshing movement of the gear cutter and the gear to be cut.

Fan Cheng method requires special machine tools to process gears, such as gear hobbing machines, gear shapers, gear shapers and gear grinding machines.

XNUMX. Forming method

It is a method of cutting out the gear tooth profile with a shaping milling cutter that matches the shape of the tooth to be cut. When milling, the workpiece is installed on the indexing head of the milling machine, and a disc-shaped or finger-shaped milling cutter with a certain modulus is used to align the gear. Milling between teeth.After machining a tooth gap, perform indexing, and then mill the next tooth gap.

The forming method is also called the profiling method. The processing equipment is simple, the tool cost is low, and the production efficiency is low. The products manufactured by this method have low precision and can only be used for low-speed and low-precision gear transmissions.
