QGC type involute spline coupling spherical roller coupling(Q/YJ16029X-2018)

Product Introduction:

The QGC type involute spline spherical roller coupling (compliant with Q/YJ16029X-2018 standard) combines spherical rollers with involute splines and is widely used in cranes, metallurgical, mining, and port equipment for connecting drums and reducers.

Core Performance Characteristics:

This coupling exhibits excellent load-bearing capacity, with a nominal torque range of 4 kN·m to 900 kN·m and a permissible radial force of 16.5 kN to 520 kN. Compared to traditional gear couplings, its load-bearing capacity is increased by approximately 30%, easily handling frequent start-stop and impact conditions.

Thanks to the spherical contact between the rollers and the bores, it possesses an angular displacement compensation capability of up to 1.5°, effectively compensating for installation errors and frame deformation. It acts as a self-aligning element, thereby significantly reducing the additional bending moment on the reducer output shaft and minimizing shaft fatigue risks.

Structural and Functional Advantages:

1. Compact Structure and Smooth Transmission: The design ensures stable torque transmission with reduced vibration and improved operational smoothness.

2. Low Noise Operation: Optimized contact mechanics between spherical rollers and involute splines reduces operational noise, improving working environment conditions.

3. Anti-Detachment Structure: Equipped with a secure locking mechanism to prevent accidental separation during heavy-duty operation, enhancing system safety.

4. Integrated Sealing System: Effectively prevents dust, moisture, and contaminants from entering, improving durability and service life under harsh working conditions.

5. Wear Monitoring Capability: Includes a wear indicator structure, enabling condition monitoring and timely maintenance to reduce downtime and unexpected failures.

Application Value:

While ensuring the safety of heavy-duty transmission, this coupling greatly facilitates condition monitoring and disassembly/maintenance of components. It is an ideal solution for heavy equipment requiring compact layout, high reliability, and efficient operation in industries such as cranes, metallurgy, mining, and port machinery.
