Orthogonal Ground Gear With Ultra-Long Integral Shafts For Industry

The combination of orthogonal ground gears and ultra-long integral shafts demonstrates significant advantages in terms of precision, rigidity, transmission efficiency, space optimization, noise and vibration reduction, as follows:

1. Ultimate Transmission Precision
▶Orthogonal gear: Utilizes high-precision gear grinding technology, ensuring extremely high tooth surface meshing accuracy.
▶Ultra-long integral shaft: Through integral manufacturing, assembly errors of traditional segmented shafts are completely eliminated, greatly improving the shaft’s coaxiality.
▶Combined effect: The repetitive positioning accuracy and meshing accuracy of the entire transmission system can reach the micron level, enabling precise control of motion trajectories. It is perfectly suitable for "micron-level transmission" scenarios such as semiconductor processing and precision machine tools.

2. High Rigidity and Strong Load-Bearing Capacity
▶Grinding gear: After processes like "heat treatment (carburizing, quenching, etc.) + grinding", the tooth surface has high hardness and uniform contact stress distribution, significantly enhancing load-bearing capacity to handle heavy-duty transmission.
▶Ultra-long integral shaft: The integral structure has no segmented connection gaps, granting extremely strong overall rigidity to stably transmit large torque and impact loads.
▶Combined effect: It meets the high-load demands of heavy industrial scenarios and maintains stable transmission under heavy loads, reducing deformation and vibration.

3. Compact Space and Efficient Transmission
▶Orthogonal shaft layout: Can "compress the length of the transmission system", helping equipment such as AGVs and precision reducers achieve compact design and saving installation space.
▶Ultra-long integral shaft: Directly caters to "long-distance transmission" needs without complex segmented connections, further simplifying the structure and saving space.
▶Transmission efficiency: Grinding gears themselves have high transmission efficiency, and integral shafts reduce connection losses, resulting in better overall transmission efficiency and lower energy consumption.

4. Low Noise, Vibration Damping, and Long Service Life
▶Low noise & vibration damping: The gear grinding process makes gear meshing smoother, greatly reducing impact and friction; the integral structure of the ultra-long shaft further minimizes vibration transmission gaps, leading to lower noise and vibration during operation. This suits "low-noise scenarios" such as medical equipment and service robots.
▶Long service life: High-precision processing + integral design reduce wear points. Combined with wear-resistant materials and heat treatment processes, the service life of components is significantly extended, cutting down maintenance frequency and costs.

In summary, the combination of "orthogonal ground gear + ultra-long integral shaft", through the synergy of "precision processing + integral design", resolves pain points of traditional transmission systems (e.g., "insufficient precision, poor rigidity, space redundancy, and high noise"). It serves as a core advantageous solution for high-end equipment transmission systems, spanning from precision light industry to heavy industry.
