What are the characteristics of Orthogonal grinding gears, extra long integral shaft gear?
Advantages
Quadrature gears are gears with axes that intersect at 90°, like bevel gears and spiral bevel gears. The grinding process uses a high-precision grinder to finish the tooth surface after heat treatment. This results in highly accurate tooth shapes, low noise, high load-bearing capacity, and a longer lifespan. Key benefits include:
- A smooth, quiet transmission with a high-quality finish on the tooth surface.
- Ability to handle high speeds, heavy loads, and precise working conditions.
- Common use in demanding fields like automotive, industrial robotics, wind power, and precision machine tools.
Long shaft parts integrated with gears or other functional components are much longer than conventional shafts. This design reduces coupling links, enhancing overall rigidity and transmission accuracy. Key benefits include:
- An integrated structure that prevents accuracy loss and faults from multi-stage splicing.
- High demands for materials and processing technology, requiring special equipment like deep hole drills and long shaft grinders.
- Ideal for long-wheelbase, high-torque transmission applications such as electric drive axles, industrial reducers, and rail transit in new energy vehicles.
New energy vehicles benefit greatly from the use of orthogonal grinding gears and ultra-long integrated shafts in electric drive axles and reducers, enhancing both transmission efficiency and NVH performance. In the world of industrial robots, high-precision orthogonal gears and long-axis integrated joints are crucial for RV reducers and harmonic drivers, ensuring top-notch performance. For wind power and rail transit, the demand for precise gear accuracy and shaft system rigidity is sky-high, but domestic leaders have stepped up, achieving import substitution and even mass exports. In industries like metallurgy, mining, and shipping, large heavy-duty gearboxes often feature an integrated design of orthogonal gears and long shafts, which boosts reliability and extends their lifespan.
