技术定义与适配语境
典型 连接销 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The Connection Pin is a critical cylindrical fastening component designed for the Jib Foot Connection in industrial machinery. It serves as a mechanical interface that aligns and secures the jib foot to its mounting structure, facilitating precise load transfer and maintaining structural stability under operational stresses. Typically manufactured to tight tolerances, it prevents relative movement between connected parts while allowing for controlled articulation or disassembly when required.

定义
The Connection Pin is a critical cylindrical fastening component designed for the Jib Foot Connection in industrial machinery. It serves as a mechanical interface that aligns and secures the jib foot to its mounting structure, facilitating precise load transfer and maintaining structural stability under operational stresses. Typically manufactured to tight tolerances, it prevents relative movement between connected parts while allowing for controlled articulation or disassembly when required.
工作原理
The pin operates on the principle of shear and bearing resistance. It is inserted through aligned holes in the jib foot and its mating component, where it resists shear forces from operational loads (e.g., lifting, rotation) and prevents lateral displacement. Its cylindrical geometry ensures uniform stress distribution, while retention mechanisms (e.g., cotter pins, locking rings) secure it against unintended removal.
材料
High-strength alloy steel (e.g.AISI 4140EN19)heat-treated to achieve a hardness of 28-32 HRC for durability and wear resistance. Surface treatments may include zinc platingblack oxide coatingor phosphate coating for corrosion protection.

常见问题

What is the primary function of a Connection Pin in a Jib Foot Connection?

It aligns and secures the jib foot to its base, transferring operational loads and preventing misalignment or detachment.

How often should Connection Pins be inspected?

Inspect during routine maintenance (e.g., every 500 operating hours) for wear, corrosion, or deformation, and replace if tolerances exceed specifications.
