No.1 & Only One Technological Capacity A drive shaft that transmits power to a machine is installed between the machine and the motor. Therefore, if the machine stops suddenly and an overload is generated, the drive shaft or the motor may break down. The hyper coupling developed by JTEKT is an interrupting device which prevents overloads from being transmitted to the motor or the drive shaft if an overload is generated. High-level design/processing technology is added to a newly-developed material aiming at ultimate performance. New-generation products with improved rolling fatigue life, superior...

is torque limiter is a torque limiter q e t r that protects drive systems for heavy loads that protects drive systems for heavy loads o i e m r y JHS Series Hyper Coupling Extensive lineup High operation accuracy Significant reduction of maintenance man-hours High durability performance Operating principle A hydraulic expansion chamber is set in the outer cylindrical part to expand with oil pressure and transmit torque to the shaft part. Torque transmission Free independent rotation The shear valve is replaced by matching the phases of the outer cylindrical part and shaft part. When oil pressure...

High operation accuracy ■ Operating torque accuracy within is realized Shear valve Hydraulic expansion chamber Outer cylindrical part 3000 Shaft part The relationship between the operating torque and oil pressure value was obtained with analysis and verified with a large static torsion testing machine to improve reliability. Support bearing Theoretical line Relationship between oil pressure and operating torque High durability performance ■ Operating durability of 150 is realized Support bearing Cover tube times or more Female coupler ・ Special surface treatment is applied to the operating   surface...

Example of use of hyper coupling (rolling mill) Occurrence of multiple in-take of rolled material The rolls stop suddenly Hyper coupling installed Excessive torque acts on the motor, pinion stand, and drive shaft Excessive torque transmission is intercepted Significant downtime needed for equipment repair/replacement Recovery within a short time Work rolls Drive shafts Hyper coupling Pinion stand Installation on this side can be also considered Examples of other applications ● Crusher ● Sizing press mill  ● Plastic molding machine ● Electric resistance welded tube mill Extensive lineup (1) Supported...
