U型夹

A U-shaped metal fastener with holes for a pin or bolt, used to connect rods, cables, or linkages in mechanical systems.

技术定义与适配语境
典型 U型夹 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。

A clevis is a U-shaped mechanical connector typically made from forged or machined metal, featuring two parallel arms with aligned holes for a clevis pin or bolt. It forms a pivotal joint when assembled with a clevis pin and cotter pin or retaining ring, allowing rotational movement while transmitting tensile or compressive loads. Commonly used in linkage systems, control rods, and suspension assemblies where adjustable or detachable connections are required.

定义
A clevis is a U-shaped mechanical connector typically made from forged or machined metal, featuring two parallel arms with aligned holes for a clevis pin or bolt. It forms a pivotal joint when assembled with a clevis pin and cotter pin or retaining ring, allowing rotational movement while transmitting tensile or compressive loads. Commonly used in linkage systems, control rods, and suspension assemblies where adjustable or detachable connections are required.
工作原理
The clevis operates as a simple pivot joint by connecting two components via a pin through its U-shaped body. The pin acts as a rotational axis, allowing angular movement while the clevis arms distribute load evenly. When secured with a cotter pin or retaining mechanism, it prevents accidental disassembly while maintaining flexibility for maintenance and adjustment.
材料
Typically carbon steel (AISI 10181045)alloy steel (41404340)stainless steel (304316)or aluminum alloys (6061-T6). Forged or machined with heat treatment (quenching and tempering) for strength. Surface treatments include zinc platinggalvanizingor powder coating for corrosion resistance.
Finish
Zinc-plated, hot-dip galvanized, or painted
Pin Diameter
Standard sizes: 1/4", 5/16", 3/8", 1/2", etc.
Arm Thickness
Varies by application (typically 3-20mm)
Load Capacity
Rated by working load limit (WLL) and ultimate tensile strength (UTS)
Temperature Range
-40°C to +200°C for standard materials
标准
ISO 2341DIN 71752SAE J429ASTM A307

常见问题

What is the difference between a clevis and a shackle?

A clevis has a U-shape with holes in both arms for a pin, designed for inline connections in linkages. A shackle typically has a rounded shape and is used for lifting or rigging with a screw pin or bolt-type closure.

How do you select the right clevis size?

Choose based on pin diameter (matching the rod end), load requirements (check WLL rating), material compatibility (environmental conditions), and arm thickness for the application's shear strength needs.
