Parallel Eccentric Coupling is a special transmission component that is distinct from traditional rigid and elastic couplings. Most standard couplings on the market are only suitable for coaxial transmission and cannot accommodate the large radial parallel offset existing in equipment. This often leads to transmission jitter, power deviation, shaft wear, and equipment shutdown.
Jiteng, as the original factory, independently researches and produces high-precision parallel eccentric couplings. Based on a compact structure, it also takes into account extremely high rigidity and strong deviation compensation capability. It can maintain zero backlash and constant-speed stable operation under high-speed and heavy-load conditions, and is an upgraded and alternative product to solve the problem of parallel shaft offset in industrial equipment.

Parallel Eccentric Coupling achieves power transmission through a precise symmetrical eccentric linkage structure, which is different from the rigid connection or elastic buffering transmission mode of ordinary couplings.
- Parallel Eccentric Linkage Transmission: Through precise structural coordination, the driving shaft and the driven shaft remain in synchronous rotation even when there is a fixed or dynamic parallel radial offset. There will be no transmission jamming due to shaft misalignment.
- Zero backlash constant-speed output: The overall structure has no transmission gap. The torque transmission is fully synchronized without any delay, ensuring that the input speed is exactly the same as the output speed, achieving constant-speed transmission.
- Flexible compensation for rigid force transmission: While maintaining high rigidity in torque transmission, it autonomously compensates for equipment installation deviations, frame deformation, and running wear, taking into account both the transmission strength and deviation compensation dual performance.
For various industry pain points related to eccentric transmission in industrial equipment, Parallel Eccentric Coupling can precisely solve the difficult working conditions that ordinary couplings cannot overcome, significantly reducing equipment failures and operation costs.
- Axis offset adaptation problem: It can solve the problems of two-axis parallel eccentricity and radial misalignment caused by equipment installation errors, frame deformation, and long-term wear, making up for the shortcomings of standard couplings that cannot adapt to large deviation working conditions.
- Transmission accuracy loss problem: It eliminates common problems such as transmission clearance, speed fluctuation, power lag, and equipment jitter under eccentric conditions, ensuring the continuous high-precision operation of precision equipment.
- Equipment wear and tear problems: It does not rely on elastic components to adapt to deviations, with a high rigidity structure that stabilizes force transmission, reducing lateral stress and abnormal wear on shafts, bearings, and seals, and lowering the equipment failure rate.
- Space installation limitation problem: Compact and lightweight structure, suitable for narrow installation spaces, solving the problem of traditional compensatory couplings being large in size and unable to adapt to the installation of precision equipment.
With its unique eccentric compensation, zero backlash precision transmission, and high rigidity durability advantages, the Parallel Eccentric Coupling is widely applicable to various industrial equipment with parallel axis offsets, covering multiple industries for precision transmission conditions.
- Automated precision equipment: Suitable for servo drive systems, non-standard automated production lines, and precision transmission mechanisms, suitable for equipment assembly deviations and running deformation-induced parallel eccentric conditions.
- Special machinery for light industry: Widely used in printing machinery, packaging machinery, textile machinery, etc., ensuring stable and precise transmission of eccentric shaft systems under high-speed operation.
- General industrial transmission equipment: Applicable to various general mechanical equipment that require dual-axis parallel linkage and have slight installation deviations, suitable for medium-speed, continuous operation conventional transmission scenarios.
- Equipment renovation and upgrade projects: Specifically designed for the renovation of old equipment, non-standard customized equipment, and easily deformed frame equipment, effectively solving the problems of poor compatibility and frequent damage of traditional coupling devices.
