Pin coupling families for industrial drive systems
The product system is organized around four clear coupling families: standard elastic pin, elastic sleeve pin, elastic pin gear and brake-wheel pin couplings. Published technical data define each family’s model range, while final selection is driven by torque, speed, shaft interface and machine duty.
Elastic Pin Couplings
Elastic pin couplings use circumferential pins and elastic elements to transmit torque while moderating shock between connected shafts.
Elastic Sleeve Pin Couplings
Elastic sleeve pin couplings place a compliant sleeve around the pins, giving the connection a defined elastic interface for offset compensation and shock absorption.
Elastic Pin Gear Couplings
Elastic pin gear couplings use a jacket-and-pin torque path and are available in cylindrical-bore and conical-bore configurations in the selected range.
Brake Wheel Pin Couplings
Brake-wheel pin couplings integrate the shaft coupling with a coaxial brake wheel, creating a compact interface for drive systems that also require braking hardware.
Featured HC, TC and ZC structures
HC, TC and ZC provide three useful starting points for understanding the range. HC uses an elastic pin arrangement with an MC nylon elastic element; TC places an elastic sleeve around the pins; ZC uses a pin-mediated jacket structure. The structural choice affects model range, interface review and maintenance access.
How a pin coupling is selected
A practical selection moves through five gates: define the drive duty, match torque, check allowable speed, confirm both shaft interfaces, then review installation and maintenance space. Pricing and availability are confirmed after the required coupling configuration is reviewed from real shaft and duty data.
| Gate | Input |
|---|---|
| Duty | Driver, driven equipment, operating pattern |
| Torque | Required transmitted duty or drive data |
| Speed | Operating r/min at the coupling |
| Shafts | d1, d2, lengths, key or taper |
| Environment | Temperature, dust, moisture, corrosion exposure |
| Commercial | Quantity and drawing/document requirements |
Applications and duty contexts
Application pages focus on the operating conditions and interfaces that influence selection. They cover cement and aggregate equipment, mining and material handling, cranes and hoisting, steel and metallurgy, industrial conveyors, and pumps/fans/general drives.
Brake wheel configurations
HCL, TCL and ZCL integrate brake-wheel geometry with three different pin-coupling structures. The brake wheel is not an accessory that can be added after selection without review; its diameter, axial position, shaft arrangement and surrounding brake hardware must be coordinated with the coupling model.
Manufacturing and inspection workflow
A coupling order should follow a controlled engineering workflow: drawing review, machining of bores and reference surfaces, dimensional inspection, assembly verification and any project-specific inspection agreed in the quotation.
Engineering support before quotation
Use the pin coupling selection guide to organize torque, speed and shaft data, review the product families when you know the required structure, or go directly to the RFQ form with a drawing. Missing data are treated as questions instead of being replaced with guessed specifications.
