Description

DT SWISS RATCHET planetary gear system technical description :

1. Press-fit side cover: The side cover that can be disassembled by hand gives the convenience of quick maintenance and specification conversion. + /-0.0XX mm press-fit tolerance. 2. Bearing: High-end cassette bearing, single contact surface seal ring achieves extremely low running resistance. 2080 N Single bearing load capacity. 3. Gear ring: It bears the inner Palin and transmits the torque to the hub shell. 450 NM test torque passed. 4. Lightweight alloy mandrel: optimize the dynamic load of the hub. After 13 times of wheel life cycle test. 5. Spring: Tested by the product life cycle of 13 times wheel set. 6. Planetary gear: the best system for transmitting torque with the lightest weight. 18 T / 20° bite angle | 36 T / 10° bite angle | 54 T / 6.6° bite angle | available options 7, alloy tower base: lightweight and anode surface treatment. In order to reduce the running resistance, the oil seal contact surface adopts high precision and extremely smooth surface treatment. +/- 0.0XX MM oil seal seat accuracy.

The bite angle refers to the idling angle that the hub sends the knight's pedaling power to the front of the wheel. We must understand that the reduction of the bite angle is limited, because the reliability of the tower foundation system also depends on the angle. What makes the planetary gear system so unique? The answer is because all the teeth on the two gears can be engaged at the same time every time. The hub of the pawl system is a control, with only a few pawls engaging at a time; in addition, the contact area of the pawl is quite small, and the tooth surface of the planetary gear system has increased a lot of occlusal area. This result has made the legendary reliability of the planetary gear system and its distinctive gear bite sound!
