The role of the safety pin on the drive shaft flange

The main function of the safety pin is to determine the axial position and axial clearance dimensions. The pin is to combine the purpose kind of accessories into one piece. For example, chain pieces and chains need pins. Pins are mainly used to connect two parts and can withstand certain shear forces. Pins are divided into cylindrical pins and tapered pins, and tapered pins are used where precise positioning is required. This is its role. Pins are a class of fasteners that play a connecting role, can constitute a static fixed connection, and can also do the relative movement with the connecting parts, mainly used in the connection of the number of parts, constituting a hinge connection.Pins: Pins are a class of standardized fasteners, which can be both static fixed connection and relative movement with the connected parts, mainly used in the articulation of two parts to form a hinge connection. Pins are usually locked with cotter pins for reliable work and easy disassembly. The international standard for pins is ISO 2341:1986

Common materials:

1.45 steel GB/T699-1999 standard provides 45 steel tensile strength of 600MPa, yield strength of 355MPa, elongation of 16%, section shrinkage of 40%, impact work of 39J . 45 steel is a common material for shaft parts, it is cheap after tempering (or normalizing), can get better cutting properties, and can obtain higher strength and toughness, etc. Comprehensive mechanical properties, quenched surface hardness up to 45 ~ 52HRC. 

2.40Cr and another alloy structural steel is suitable for medium precision and high-speed shaft parts, such steel after quenching and tempering has good overall mechanical properties. 

No. 45 steel is widely used in machinery manufacturing, and the mechanical properties of this steel are very good. But this is a medium carbon steel, quenching performance is not good, 45 steel can be hardened to HRC42 ~ 46. So if you need surface hardness, but also want to play 45 # steel superior mechanical properties, often 45 # steel surface quenching (high-frequency quenching or direct quenching), so you can get the required surface hardness.
