Drum Gear Coupling With Intermediate Shaft

Rokee^® Customized Drum Gear Coupling With Intermediate Shaft for Customers, Rokee^® is a well-known high-quality supplier of couplings and technical services in China.

The drum toothed coupling with intermediate shaft is a derivative model of the standard drum toothed coupling, which adds an intermediate connecting shaft and achieves long-distance transmission and complex deviation compensation through a three-stage structure.

Technical Characteristics

1. Modular design
   Composed of two external half couplings, a middle shaft sleeve, and an inner gear ring, the length of the shaft sleeve can be customized as needed (commonly 500-3000mm), with a maximum compensation angular displacement of 1.5 °± 0.2 °
   The typical model WGJ/WGT series is forged from 42CrMo alloy steel, with a tooth surface carburizing and quenching hardness of HRC58-62, and a fatigue life of over 10 ^ 7 cycles

2. Dynamic compensation mechanism
   The intermediate shaft design can absorb axial displacement of ± 15mm (200% higher than ordinary drum gear couplings), suitable for mining and metallurgical equipment with foundation settlement
   The double drum shaped tooth structure forms a "double joint" effect, with angular compensation capability added up to 3 °, while reducing single-sided tooth surface contact stress by 40%

Long distance transmission solution

1. The intermediate shaft is designed with hollow forgings (wall thickness ≥ 20mm), which reduces weight by 35% compared to solid shafts while maintaining a torque capacity of 90%
   

2. Special centering structures (such as conical positioning sleeves) ensure installation accuracy of ≤ 0.05mm/m, avoiding long axis vibration

Extreme working condition adaptation

1. High temperature type: The intermediate shaft is equipped with heat dissipation fins, and the temperature resistance range is extended to -50 ℃~300 ℃ (for metallurgical rolling mills)
   

2. Corrosion resistant type: stainless steel intermediate shaft+special lubricating grease, suitable for salt spray environments such as offshore platforms
