Three basic parameters of gear
Model, pressure angle, number of teeth areGear
Three basic parameters. Based on this parameter count the size of the gear. The following content, for the basic parameters of these three gears, the editor of Shirida has compiled a detailed instructions for you:
1. Gear modulus:
Models: Indicators of the size of the gear. Model M = 1 (P = 3.1416), Model M = 2 (P = 6.2832), Model M = 4 (P = 12.566)
Models can get the tooth distance (p) by the periability. The distance between the teeth is the length of the adjacent two teeth. P = Pay rate X modulus (nm)
In the United States, Britain and other countries, DP (diameter) 耒 means the size of the right wheel. The conversion relationship with the mold M = 25.4/dp
Second, weekly festival (teeth distance):
The weekly festivals are the circular tooth distance. That is tooth distance (P). The conversion relationship with the mold M = cp/π.
Third, high teeth and thick teeth:
1. The benchmark for the thickness (s) is half of the tooth distance (p). S = πm/2 p = πm
2. High tooth height (H) is the height from the top of the tooth to the root of the teeth. The height of the gear is determined by the mold (M). H = 2.25m (= Goblon high+teeth height)
3. High tooth root (HF) is a height from the root of the tooth to the division line (midline). HF = 1.25M
4. The height of the tooth top (HA) is the height from the top of the tooth to the division line (midline). (The point line is the benchmark line to calculate the size of the rack). ha = 1.00m
Fourth, stress angle:
Pressure angle (A) is the tilt of the gear surface, which is a parameter that determines the gear tooth shape, and usually uses 20 °.
Gear is generally used with products such as gears, bars, gear shafts, etc. to achieve the transmission effect
