Large Spur Gear Rack
The calculation formula of the Gear Rack modulus is divided into the calculation formulas of the spur gear rack and the helical gear rack, which are respectively as follows for reference.
1. Formula for calculating the modulus of spur gear rack: modulus = pitch ÷π
2. The calculation formula of the helical gear rack modulus: modulus = pitch * COS ÷ π
In the precision gear rack design, the modulus M is the most important and most important parameter in the process of making the gear rack. Its size determines the size of the tooth and directly relates to the cost of manufacturing the gear rack, which determines the price of the gear rack. Generally, under the premise of the structure, the modulus M should be slightly larger, which is especially important for the start of the transmission with impact load.
Note: The above formula calculation formula of the gear rack is for reference only. If you have more questions, you can help the technical requirements of Fengmao: 0769-81876428.

The calculation formulas of pitch p, full tooth height h, root height hf, tip height ha, cogging width e, and tooth thickness s are as follows:
1. Pitch P = πm
2. Full tooth height h = ha + hf = (2 ha * + c *) m
3. Root height hf= ha+c=( ha*+c*)m
4. The top of the tooth is high ha = ha * m
5. Cogging width e = πm / 2
6. Tooth thickness s = πm / 2
