Axle rotates, and determines in the central shaft of gear ring 300, the central shaft of dynamic gear ring 400 and sun gear 100
Mandrel is coaxial, rotates more steady, saves installing space.
The side of the wheel body of sun gear 100 is provided with limiting section, it is possible to limit floating planet gear 200
Movement on a direction of the central shaft of sun gear 100, dynamic gear ring 400 is provided with limiting plate,
After dynamic gear ring 400 engages with floating planet gear 200, limiting plate can limit floating planet gear 200
Along the movement of other direction of the central shaft of sun gear 100, i.e. floating planet gear 200 can normally with
Sun gear 100 external toothing, it is also possible to normal with determine gear ring 300 and dynamic gear ring 400 internal messing, transmission
More safe and reliable.
Move gear ring 400 and determine the gear ring 300 axis direction spacing distance along sun gear 100, i.e. moving tooth
Circle 400 does not contacts with the end face determining gear ring 300 when rotating, and reduces frictional force, rotates more
Steadily, noise is little, and service life is long.
