Rokee® Customized RODA04-05 Crown Gear Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
RODA crown gear coupling is an innovative rigid flexible coupling device, consisting of a precision matched inner gear ring and a flange half coupling with outer teeth at its core. Compared with traditional spur gear couplings, its revolutionary design lies in the use of a spherical drum structure for the outer teeth, with a spherical tooth surface centered on the gear axis, while increasing the tooth flank clearance. This design is not a simple form change, but an engineering optimization based on complex force analysis, which enables the coupling to achieve multi tooth simultaneous contact during transmission, significantly improving load distribution.
Core advantages
Enhanced compensation capability: The increased tooth flank clearance allows for greater axial (maximum ± 15mm), radial (maximum ± 5mm), and angular displacement compensation (maximum 1.5 ° -2.5 °)
Optimization of contact conditions: The drum shaped tooth surface increases the contact area between the inner and outer teeth by more than 30%, avoiding the edge compression problem of straight tooth couplings and extending their service life by 30% -50%
Core structural components
Internal gear ring: Made of high-strength alloy steel (such as 42CrMo) that has undergone carburizing and quenching treatment, with a tooth surface hardness of HRC58-62
External gear sleeve: Unique drum shaped tooth design, tooth tip curvature radius R=5-8m (varies according to specifications), pressure angle is usually 20 ° or 25 °
Lubrication system: Optional forced thin oil lubrication or segmented grease lubrication structure.
