Product Details

Technical Specifications

Connection method

The product features a compact design, easy installation and maintenance, and exceptional cost-effectiveness.
It exhibits high elasticity, boasts strong shock‑absorption and vibration‑damping capabilities, and can effectively regulate the torsional vibration characteristics of the transmission system, thereby reducing vibration and noise.
It can operate at higher rotational speeds and exhibits excellent capability to compensate for installation misalignments in the axial, radial, and angular directions.
It can be specially designed according to the specific coupling method and dimensions of the main and auxiliary machines.
An emergency structure with elastomer failure.
An elastomer made from a high‑temperature‑resistant specialty rubber, with an allowable service temperature range of –45°C to 120°C.
HQTQWX is suitable for connecting the diesel engine output to the universal joint shaft.

Applications:

The products are widely used in applications such as diesel engines, generators, water pumps, mud pumps, compressors, construction machinery, wind power generation systems, locomotive transmission systems, and test benches.
