RSK-GICLZ Drum Gear Coupling Wide Type Intermediate Shaft Customization used in industrial applications Suppliers, Company - Jiangsu Rokang Heavy Industry Technology Co., Ltd.

Specification

RSK-GICLZ type intermediate shaft drum gear coupling is a heavy-duty gear coupling designed for ultra-long span transmission systems. Its core structure connects two drum gear half-couplings via an elongated intermediate shaft, effectively compensating for combined radial, angular, and axial displacements under large shaft distance conditions. It is primarily used in industrial applications such as metallurgical roller tables, mining machinery, and large conveying equipment that have specific requirements for transmission distance and misalignment compensation capability.

Describe

I. Core Advantages (Compared to Spur Gear Couplings)

Excellent Angular and Radial Misalignment Compensation

Barreled Design: The outer edges of the external teeth are machined into a spherical (barreled) shape, providing larger backlash.
Effect: Allows the internal and external teeth to mesh at larger angles and accommodates certain radial offsets. Typically, angular compensation can reach 1°30′, and radial compensation is significantly better than spur gear couplings. This is its most fundamental advantage.

High Load Capacity, Low Wear, Long Service Life

Surface Contact: Under misalignment, barreled teeth maintain surface contact, avoiding the edge loading and stress concentration common in spur teeth.
Effective Load Distribution: The load is distributed more evenly across the tooth width, reducing pressure per unit area.
Effect: Greatly increases the coupling's load capacity and shock resistance while reducing wear and extending service life.

Automatic Alignment and Self-Centering Capability

The spherical meshing characteristic of barreled teeth provides a degree of "self-adaptability." It can automatically adjust for minor misalignment caused by installation errors or foundation settling, protecting the bearings of connected equipment.

II. Structural and Other Characteristics

Compact Structure, High Torque Transmission

For the same size, barreled gear couplings can transmit higher torque, offering high volumetric efficiency.

Requires Lubrication and Sealing

Lubrication: As a rigid movable coupling, its tooth surfaces require good lubrication (typically oil or grease) to minimize wear and heat generation.
Sealing: Standard equipment includes seals such as O-rings or lip seals to prevent lubricant leakage and ingress of external contaminants. The reliability of the seal directly impacts the coupling's lifespan.

High Reliability, Suitable for Harsh Conditions

Due to their durability, GIICL-type couplings are widely used in applications involving continuous operation, heavy loads, medium to high speeds, and slight misalignment. Examples include: metallurgical rolling mills, mining machinery, heavy lifting equipment, marine propulsion systems, and generators.
