Component Specifications

Definition
Connection ends are specialized terminal sections of actuators and shafts designed to facilitate reliable mechanical coupling with mating components such as couplings, gears, pulleys, or other shafts. These interfaces ensure precise alignment, torque transmission, and load distribution while maintaining structural integrity under operational stresses. They are critical for power transmission systems in industrial machinery.
Working Principle
Connection ends function by providing standardized geometric features (such as keyways, splines, threads, or tapers) that interlock with corresponding features on mating components. This creates a secure mechanical joint that transmits rotational motion and torque while resisting axial and radial displacement. The design ensures minimal backlash and vibration, optimizing energy transfer efficiency.
Materials
Typically manufactured from high-strength alloy steels (e.g., AISI 4140, 4340), stainless steels (e.g., 304, 316), or hardened tool steels. Surface treatments may include nitriding, carburizing, or chrome plating for enhanced wear resistance and corrosion protection.
Technical Parameters
  • Hardness 45-60 HRC
  • Diameter Range 5-200 mm
  • Surface Finish Ra 0.8-3.2 μm
  • Tolerance Class IT6-IT8
  • Torque Capacity Up to 5000 Nm
Standards
ISO 4156, ISO 773, DIN 5480, DIN 6885

Frequently Asked Questions

What are the main types of connection ends?

Common types include keyed ends (with keyways), splined ends (involute or straight splines), threaded ends, tapered ends (with locking mechanisms), and flanged ends for direct bolting.

How do I select the right connection end for my application?

Selection depends on torque requirements, rotational speed, alignment precision needed, space constraints, and maintenance considerations. High-torque applications typically use splined connections, while keyed connections are common for moderate loads.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
