GCJ Connected to intermediate shaft drum gear coupling(Q/YG 13015X-2018)

Product Overview:

The GCJ-type crowned-tooth gear coupling with an intermediate shaft (Standard No.: Q/YG 13015X-2018) is a precision mechanical component designed specifically for medium-to-long-distance power transmission. Classified as a flexible coupling without elastic elements, it incorporates an "intermediate shaft" structure between two crowned-tooth coupling halves. This design effectively resolves challenges regarding torque transmission and displacement compensation in long-distance shaft connections, ensuring the continuous and stable operation of industrial equipment under complex working conditions.

Core Design and Technical Advantages:

1. Superior Displacement Compensation: At its core lies a meticulously designed crowned-tooth structure featuring precise meshing between internal and external teeth. This design not only offers exceptional load-bearing capacity but also effectively compensates for angular, radial, and axial misalignments caused by installation errors or operational fluctuations, thereby minimizing stress impacts on connected bearings and equipment.

2. Optimized for Long-Distance Transmission: Unlike standard couplings, the GCJ model utilizes an intermediate connection, making it particularly suitable for applications requiring a significant span between shaft ends and offering greater layout flexibility.

3. Shock-Absorbing and Stability-Enhancing Design: High-performance cushioning elements are positioned between the hubs to effectively absorb mechanical shocks and suppress vibrations during operation. This significantly improves system stability and protects precision motors or gear reducers.

4. High-Strength Materials and Manufacturing: Manufactured from high-quality steel or alloy steel, the product exhibits excellent fatigue and corrosion resistance, capable of withstanding heavy loads and harsh industrial environments (such as high temperatures, high humidity, or dusty conditions).

5. Maintenance-Friendly Modular Structure: Thanks to its rational industrial design, the coupling supports rapid disassembly and assembly, facilitating routine inspections, lubrication, and parts replacement, thereby significantly reducing downtime and maintenance costs for enterprises.

Note:

1. The mass and moment of inertia are approximate values calculated according to the maximum cylindrical shafthole diameter and the length of the intermediate shaft L5min.
2. Under normal circumstances, the active end of the shaft hole of the coupling is cylindrical, and the driven end isa flat hole. If necessary, both ends can be cylindrical.
3. Models 1~5 can be selected according to GB/T3852 if you need Y-type shaft extension.
4. For flat bore shaft holes, the limit tolerance of d₂ and B is H9.
