Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of modified form planet wheel decelerator, including it is driving gear 1, some first driven
Gear 2, some second driven gears 3, the first gear ring 4, the second gear ring 5 and fixed plate 6, the circular row of the first driven gear 2 is in actively
The periphery of gear 1, and driving gear 1 and the first driven gear are ratcheting, and the diameter of driving gear 1 is less than the first driven gear 2
Diameter, the first gear ring 4 is set in the periphery of the first driven gear 2, and the first gear ring 4 in enclose and be equipped with crown with periphery,
The circular row of second driven gear 3 in the periphery of the first gear ring 4, and the first gear ring 4 respectively with the first driven gear 2 and the second driven tooth
Take turns 3 ratcheting, the second gear ring 5 is set in the periphery of the second driven gear 3.Fixed plate 6 is located at driving gear 1, the and of the first driven gear 2
The side of second driven gear 3, fixed plate 6 rotates with driving gear 1, the first driven gear 2 and the second driven gear 3 respectively to be connected
Connect；First driven gear is driven by the rotation of driving gear, because the diameter of driving gear 1 is less than the first driven gear 2
Diameter, it can be achieved first and slow down；First gear ring 4 is driven by the first driven gear 2, realizes second and slows down；First gear ring is again
Drive the second driven gear 3 to drive the second gear ring 5 to rotate, and then realize that third time is slowed down；Compared with traditional planetary reduction gear,
