Compared with prior art, the beneficial effects of the invention are as follows：
1, a kind of transmission mechanism of open mill of the present invention, is mainly the cyclic train in device using double epicyclic gear drive device
Have many advantages, such as that structure is compacter, bearing capacity higher, it is light-weight：A is since it has the characteristics of power dividing, in the feelings carried
Under condition, with the increase of planetary gear, appearance and size reduces therewith；B reasonably applies internal messing, reduces axially and radially
Size, keep structure very compact and bearing capacity have it is very high；C gear ranges are big；D transmission efficiencies, stable movement, shock resistance and
The ability of vibration is strong, it is simple to safeguard.
2, the installation fixation of a kind of transmission mechanism of open mill of the present invention, planetary driving device is by equalising torque mechanism
It realizes.Moment arm is bolted on the output flange of planetary driving device, then passes through two sets of sliding axles by coupling bar
It holds and is connected in moment arm support base with axis pin, moment arm support base is bolted fixed on mill machine base,
Ensure that planetary driving device is not tumbled with this, securely and reliably.When mobile roll shaft, entire planetary driving device follows roll shaft
It is mobile simultaneously, at this time according to slider-crank mechanism principle（See Fig. 4）, the tilting moment that planetary driving device device is born, due to
The effect of equalising torque mechanism, entire transmission device can smoothly work.
3, a kind of transmission mechanism of open mill of the present invention, universal joint shaft is not needed using the open mill of planetary driving device
Device does not need the mounting seat of motor and speed reducer.Therefore using the weight of equipment of the double roller cylinder open mill of novel transmission mechanism
Mitigate significantly.
