The difference between the forming method and the forming method of gear tooth processing and the description of the advantages and disadvantages

The differences and advantages and disadvantages of gear tooth processing forming method and forming method are as follows, for reference and understanding. If you have more questions or related needs, you can consult EP free of charge.

XNUMX. The difference between the forming method and the forming method of gear tooth processing:

1. The generative method uses tools and gears to form a generative motion to process gears.There are two ways of gear shaping and gear hobbing, and gear finishing (grinding and shaving) is also a generative method.

2. Generating gear grinding has single-tooth indexing generating method (conical grinding wheel grinding teeth and double-disc grinding wheel grinding teeth) and continuous indexing generating method. For details, please refer to the article "Generating method of gear grinding"I learned.

3. The forming method is to directly cut the gear tooth profile on the milling machine with a forming tool that is the same as the tooth profile curve between the teeth.There are not many applications of forming method for tooth grinding. For specific instructions, please refer to the article "Gear processing method of forming method gear grinding processing"View related instructions.

XNUMX. The advantages and disadvantages of gear tooth processing generation method and forming method:

1. Advantages and disadvantages of developing method:

a. Advantages:Gear processingThe precision and efficiency are higher than the forming method, and it is more widely used.Gears with the same modulus and tooth profile angle but different numbers of teeth can be machined with the same tool.Among them, gear hobbing is more convenient than gear shaping and has a wider range of applications; gear shaping can be used in positions where internal gears and double or multiple gears with too short retracting distance can not be machined; gear grinding is generally used on hard tooth surfaces But the efficiency is slightly lower; gear shaving cannot be used on hard tooth surfaces but the processing efficiency is high.

b. Disadvantages: The specific processing method must be specified. Generally speaking, there is no particularly big disadvantage, and it is widely used at present.

2. Advantages and disadvantages of forming method:

a. Advantages: Gears can be obtained on a milling machine. Considering that the equipment is restricted, it is generally used for single-piece processing.

b. Disadvantages: The machining accuracy and efficiency are lower than the generative method, because this method is tooth-by-tooth machining and discontinuous. In order to reduce the number of tools, the number of teeth is segmented, and a knife is used within a segment of the number of teeth, so the tooth profile will be Come systematic error.

The above is the description of the differences and advantages and disadvantages of the gear tooth processing forming method and the forming method that the EP editor shared with you today, including but not limited to, if you have any unclear points or related needs, you can seek help from our technology.
