Serration
Optimum selection of the dimensions and number of serrations of the fir-tree root has been made possible by finite element calculations of stresses in the shaft and root. Because of unavoidable inaccuracies in manufacture, the pit between the supporting planks of the individual fir-tree tips varies.
Flanges
A serrated finish, either concentric or spiral, is required with 30 to 55 grooves per inch and a resultant roughness between 125 and 500 micro inches. This allows for various grades of surface finish to be made available by flange manufactures for the gasket contact surface of metal flanges. Serrated Finish The most used Surfaces Stock Finish
Manufacturing DIN 5481 Type Spline Serrations
The DIN standard fixes spline serrations both internal and external with a constant space angle of 60° for numbers of teeth between, 28 to 42 and pitch diameters from 7.0 mm up to 60.0 mm. For larger splines,, a constant space angle of 55° is specified for numbers of teeth between, 41 to 81 and pitch diameters of 60.0 to 120.0 mm.

Learn How to Sharpen a Serrated Knife | Outdoor Life
A serrated blade is great for ripping through heavy rope and other fibrous materials, and also keeps an edge longer due to its increased surface area. But, the reality of using knives is that even the best serrated knives with great steels will eventually dull, and need to be sharpened.
Learn How to Sharpen a Serrated Knife | Outdoor Life
Step 2: Raise a Burr. The reason an edge is dull is actually because of damage, even if the damage is very minor. When you sharpen a blade, you're removing metal to grind the damage away, and then refining the edge to make it smooth and sharp again. The finer the edge, the sharper it will be. In this step, you will be making short …
Inside, outside serrations? Types of center lock locking rings
The outer serration type lock ring is used for shafts that cannot be passed through the inner serration. The Y24698030 is a type of lockring with the teeth on the outside of the ring. Since the teeth for tightening are on the outside, the hole for the shaft is large enough to use a large shaft (e.g., 15 mm).
SMART BLADE
Improve the noise emission of your turbines by installing serrations. Noise regulations force many operators to run their turbines in a noise-reduced mode especially at night. Serrations help to reduce noise emissions and bring the turbines back to a higher mode of operation. This can increase your AEP by up to 5%.

The serration density on both the mesial and distal carinae is substantially greater than in morphotype B, with mesial denticles ranging from 15 per mm (NHMUK PV R36779) to 18 per mm (NHMUK PV R37920) and distal denticles from 13 per mm (NHMUK PV R36779) to 17.4 per mm (NHMUK PV R37920). By contrast, morphotype B mesial …
