A detailed guide to spur gear design covering teeth count, module, pressure angle, and face depth. Includes formulas and real-world considerations for engineers.
-
A comprehensive guide to gear terminology, covering key concepts like modules, addendum, dedendum, backlash and clearance in mechanical gear systems.
-
Knurling adds textured patterns to surfaces, enhancing grip and bonding. Applied by machine or hand-applied, it’s used in tools, connections, and over-molding.
-
Shot peening is a crucial metal treatment process that enhances the fatigue resistance, durability, and surface hardness of components. This technique involves firing small beads at high velocity onto a material’s surface, inducing compressive stress and improving mechanical properties.
-
Galvanisation coats iron/steel with zinc to prevent corrosion. The process helps to improve durability and lifespan.
-
Black oxide coating is a chemical surface treatment for ferrous materials which enhances corrosion and wear resistance.
-
Passivation builds a protective layer on metal surfaces, enhancing corrosion resistance. It’s vital for stainless steel, restoring protection after fabrication.
-
Pickling is a metal cleaning process using acidic baths to remove impurities. It’s simple, affordable, and improves corrosion resistance. While effective, it has drawbacks like solution degradation and hazardous waste production.
