The syntagmatic and connection relationship of three seal assembly conventional hermetic class standard parts are arranged using any method known in the art and connection, and
The invention emphasis of non-the present embodiment, is not just further described here.
Preferably, the primary planet wheel 3 is three to one kind as the present embodiment, and three primary planet wheels 3 are in institute
It states 2 side of sun gear to be evenly distributed, each primary planet wheel 3 internal tooth phase with the sun gear 2 and the gear ring 5 respectively
Mutually engagement.The secondary planet wheel 4 is three, and three secondary planet wheels 4 are evenly distributed in 5 side of gear ring, respectively
The secondary planet wheel 4 is intermeshed with the external tooth of the gear ring 5 respectively.The driven gear 6 is also three in the cabinet 11
A, the driven gear 6 is arranged corresponding to the secondary planet wheel 4.It is arranged using the above structure, is had according to known triangle
Stability when work, guarantees that 11 stress of cabinet more balances, avoids shaking.The novel planetary gearbox of the utility model works
More steady, more can be reduced noise, (that is: the revolution of cabinet 11,7 rotation of bistrique, the revolution of cabinet 11 and 7 rotation of bistrique generate outside
Centrifugal force can cancel out each other, work it is more stable, gear, bearing can also obtain enough lubrications, and noise is small, be effectively reduced maintenance at
This).
By adopting the above technical scheme, board delivers power to sun gear 2, and sun gear 2 is connected to cabinet 11 by bearing
Middle part, and realization transmission is engaged with primary planet wheel 3, since the primary planet axis 31 of primary planet wheel 3 is fixed in cabinet 11,
In transmission process, primary planet pinion 32 can the rotation on primary planet axis 31.Again since gear ring 5 is connected further through bearing
In on sun gear 2, the secondary planet axis 41 of secondary planet wheel 4 is also to be fixed in cabinet 11, while gear ring 5 is solid with board again
It is fixed.So the internal tooth of gear ring 5 engages realization transmission with primary planet wheel 3, the external tooth of gear ring 5 engages realization with secondary planet wheel 4
(that is: primary planet wheel 3 surrounds sun gear walking movement in the internal tooth of gear ring 5, and secondary planet wheel 4 is centered around gear ring 5 when transmission
External tooth walking movement), primary planet wheel 3 and secondary planet wheel 4 are all in rotation, the revolution of 11 relative gear rings 5 of cabinet.
In 11 relative gear rings of cabinet, 5 process of revolution, the external tooth of gear ring 5 is engaged with secondary planet wheel 4, secondary planet axis 41 with
Driven gear 6 engages, since the secondary planet axis 41 of secondary planet wheel 4 is fixed in cabinet 11, for installing driven gear 6
Output shaft 61 is again to be rotatably installed on cabinet 11 (driven gear 6 is fixedly connected in the first end of output shaft 61 by key),
So driven gear 6 also drives 61 rotation of output shaft simultaneously when cabinet 11 revolves.Bistrique 7 is connected by key in output shaft 61
Second end on (bistrique 7 here can also be connected in the second end of output shaft 61 by conventional mounting structure), so mill
First 7 with 61 rotation of output shaft.
Therefore, when work, cabinet 11 revolves, and also the autobiography on cabinet 11, cabinet revolution generate bistrique 7 with bistrique rotation
Outside centrifugal force can cancel out each other, thus make the bistrique 7 for exporting axis connection that can smoothly work, and flexible operation is laborsaving,
Working efficiency greatly improves.
In short, the novel planetary gearbox of the utility model, can be realized the rotation of single layer gearbox, revolution, work area
Increase, gearbox gears rotation generates outside centrifugal force, can cancel out each other, gear, bearing obtain enough lubrications, make an uproar
The small board work of sound is more stable, and flexible operation is laborsaving, and operator's operational effectiveness is fully used, and working efficiency increases, system
It makes, maintenance cost is effectively reduced.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
