What is gear grinding?
Gear grinding is a process that uses grinding methods to process tooth surfaces to achieve high precision and high quality requirements. Traditional tooth surface processing methods mainly include milling, planing, broaching, etc., but the quality and precision of the tooth surfaces processed by these methods are relatively low, which is not conducive to the working efficiency of transmission machinery.
Scope of application of gear grinding
Gear grinding is suitable for the tooth surface processing of parts that require high precision and high wear resistance. For example: gears, couplings, reducers, transmission chains, etc. These transmission parts have high requirements for tooth surface accuracy and surface smoothness, so gear grinding technology is required for processing.
What are Advantages of gear grinding?
Compared with other tooth surface processing methods, gear grinding has obvious advantages, including:
1. High precision: Gear grinding can process very precise tooth surfaces, and the tooth shape error and tooth pitch error can be controlled within a small range to ensure the accuracy of transmission.
2. High wear resistance: Gear grinding can make the tooth surface smoother and flatter, with less wear on the tooth surface and better durability.
3. Low noise: Gear grinding can make the tooth surface smoother and reduce the noise during transmission.
What is Gear grinding process?
The processing technology of gear grinding mainly includes the following steps:
1. Select suitable gear grinding machine tools, grinding heads and grinding fluids.
2. Carefully formulate grinding plans, including parameters such as tooth surface shape, tooth pitch, and accuracy.
3. Perform initial grinding and fine grinding, where initial grinding is used to remove excess and surface protrusions, and fine grinding is to further improve the accuracy and surface finish of the tooth surface.
4. Detect indicators such as tooth surface accuracy and surface smoothness, and perform post-processing if necessary.
What are Problems with gear grinding ?
Gear grinding, as a processing technology, also has some problems in the application process, such as:
1. The processing technology is complex and requires a lot of equipment and human resources.
2. The grinding speed is relatively slow and the processing efficiency is not high.
3. After grinding, the surface of the parts is passivated and oxidized, and protective treatment is required.
