【概要描述】As a device that connects the power source to the working machine, the hydraulic coupling is a hydrodynamic transmission mechanism that transmits torque by means of changes in the momentum moment of the fluid. During operation, mismatched transmission devices can easily lead to problems such as overload on the working machine, prolonged electric starting times, and unstable power output, resulting in machine wear and damage. To address these issues, Guangdong Zhongxing, a well-established coupling manufacturer, has custom-designed YOX series limited-torque couplings, including models YOXIIz, YOXAZ, and YOXA.

Hydraulic couplers are widely used in various mechanical equipment across industries such as power generation, iron and steel, metallurgy, mining, coal, building materials, chemical engineering, ports, lifting, transportation, and construction machinery—including belt conveyors, scraper conveyors, chain conveyors, screw conveyors, and bucket elevators.
The YOXIIz and other YOX series couplers, as torque-limiting couplers, have the following advantages:
1. To enhance the starting capability of squirrel-cage induction motors, we can utilize the motor’s peak torque as the starting torque, thereby avoiding the unreasonable mismatch phenomenon of “using a large horse to pull a small cart.”
2. Shorten the starting time of the electric motor and reduce the inrush current during the starting process.
3. Prevent power overload and protect the motor and working machinery from damage due to overload.
4. Reduce vibration and impact during the starting process.
5. In multi-motor drive systems, it can ensure that each motor starts independently, achieve power balance, and provide a starting torque limit ranging from 1.2 to 1.6 times the rated torque.
6. Simple and reliable structure, no mechanical wear, and requires no special maintenance.
7. Able to work in a variety of harsh working environments.
