Hypoid Grinding Gear Hardened Finish For Four-Series Speed Reducer

Dingsco's hypoid gears adopt a unique helical tooth design, with smooth tooth surfaces, and the axes of the main and driven gears do not intersect and there is an offset distance. This design allows for a larger contact area when the gear is engaged, resulting in a significantly higher load carrying capacity.

Specific structural features include;
1.Tooth surface shape: Hyperboloid curve design is adopted, and the tooth surface contact area is more evenly distributed along the tooth width and tooth height, effectively dispersing the load.
2.Helix angle difference: The helix angle of the driving wheel is greater than that of the driven wheel, which makes the driving wheel larger in diameter and higher in strength, and at the same time achieves smooth transmission through sliding friction.
3.Offset design: The driving axle can be offset up or down.

With its high load-bearing, low-noise and compact design, hypoid gears have become the core components of K series gear units, and have been extended to F series orthogonal shaft models. Its design blends materials science with precision manufacturing technology for a wide range of applications in heavy industry and automation. With the improvement of industry standards and the innovation of patented technology, hypoid gears continue to improve in terms of efficiency, reliability and adaptability, and have become one of the key solutions for modern transmission systems.
