技术定义与适配语境
典型 螺纹端 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 threaded end is a precisely machined terminal section of a hydraulic cylinder piston rod featuring external threads designed to create a secure mechanical connection with mating components such as cylinder heads, clevises, or other attachments. This component transmits linear force from the piston rod while maintaining alignment and preventing disconnection under operational loads.

定义
The threaded end is a precisely machined terminal section of a hydraulic cylinder piston rod featuring external threads designed to create a secure mechanical connection with mating components such as cylinder heads, clevises, or other attachments. This component transmits linear force from the piston rod while maintaining alignment and preventing disconnection under operational loads.
工作原理
The threaded end converts the linear motion of the piston rod into a secure mechanical connection through threaded engagement. When torque is applied to the nut or mating component, the threads create axial clamping force that prevents separation while allowing precise adjustment of the connection length. The thread geometry distributes stress evenly along the engaged length to withstand tensile, compressive, and shear forces during hydraulic cylinder operation.
材料
Typically manufactured from high-strength alloy steels such as AISI 41404340or 1045 carbon steel with hardness ranging from 28-32 HRC. Surface treatments include chrome plating (20-40μm thickness) for corrosion resistance and reduced frictionor nitriding for enhanced wear resistance in high-cycle applications.
Thread Size
M20 to M100 or equivalent
Thread Type
Metric (M), Unified (UNC/UNF), or Acme threads
Thread Class
6g for metric, 2A/2B for unified
Thread Length
1.5D to 2.5D (where D is thread diameter)
Surface Finish
Ra 0.8-1.6 μm

Tensile Strength
800-1200 MPa
标准

常见问题

What are the common failure modes of threaded ends in hydraulic cylinders?

Common failures include thread stripping due to over-torque, fatigue cracking at the thread root from cyclic loading, corrosion pitting in harsh environments, and galling from improper lubrication during assembly.

How do I select the proper thread type for a hydraulic cylinder application?

Select based on load requirements: metric threads for standard applications, unified threads for North American equipment, and Acme threads for applications requiring frequent adjustment. Consider thread engagement length (minimum 1.5× diameter), material strength, and corrosion protection requirements.
