Description
Technical field
The utility model relates to Vertical Mill main transmission retarder technical field, is specifically related to a kind of planetary gear mechanism.
Background technique
The roller mill speed reducer conventional construction generally is divided into three kinds of structural types: two-stage drive mechanism, three grades of drive mechanisms or duplicate rows star structure.The two-stage drive mechanism is vertically upward planetary gears realization deceleration, break-in and transmitted power through gear transmission of one-level rigging-angle cone and one-level input shaft promptly; Three grades of drive mechanisms have increased the transmission of one-level parallel-axes gears on the basis of former two-stage drive mechanism, with needing one-level large speed ratio, the secondary moment of transmitting of large-size bevel gear to distribute to the two-stage gear transmission originally; Duplicate rows star structure is that the one-level bevel gear drive adds the transmission of two-stage NGW type planetary pinion again.
Because above three kinds of transmission result formats, the inner teeth wheel set is cascaded structure, has only an output terminal, and therefore when transmission was high-power, the size of gear pair and body was very huge, brings inconvenience for processing, assembling, installation, use etc.
Summary of the invention
In order to overcome the shortcoming of above-mentioned existing technology, the purpose of the utility model is to provide a kind of planetary gear mechanism, has improved the bearing capacity of retarder, has reduced volume and weight.
In order to achieve the above object, the technological scheme taked of the utility model is:
A kind of planetary gear mechanism; Comprise bevel pinion 6, the input shaft of bevel pinion 6 is connected with power with outside motion, and bevel pinion 6 connects and composes one-level rigging-angle cone gear drive with bevel gear wheel 7; The output shaft of bevel gear wheel 7 is connected with first order sun gear 9; First order sun gear 9, first order planet wheel 1, first order ring gear 2 and first order planet carrier 10 connect and compose first order planetary gears, and first order ring gear 2 connects firmly with second level sun gear 8 is in the same place, and second level sun gear 8, second level planet wheel 3, second level ring gear 4 and second level planet carrier 5 connect and compose second level planetary gears; Second level planet carrier 5 is fixed; First order planet carrier 10 connects firmly with second level ring gear 4 is in the same place, and motion has realized shunting with power after through first order planetary gears, and a part is exported through first order planet carrier 10; Remainder is delivered to second level sun gear 8 and second level planet wheel 3 through first order ring gear 2 successively, ring gear 4 outputs through the second level.
Described first order planetary gear mechanism, second level planetary gear mechanism adopt the structure of the multirow star-wheel of maximum 7 planet wheels.
The planet wheel of described first order planetary gear mechanism, second level planetary gear mechanism adopts the compliant pin load balancing structure.
Model utility has overcome the inconvenience that traditional roller mill speed reducer drive mechanism component bring for processing, assembling, installation, use etc.; Planetary gear mechanisms for two stages is exported simultaneously; Become series connection and be parallel connection, improved the bearing capacity of retarder, reduced volume and weight.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Referring to accompanying drawing, a kind of planetary gear mechanism comprises bevel pinion 6; The input shaft of bevel pinion 6 is connected with power with outside motion; Bevel pinion 6 connects and composes one-level rigging-angle cone gear drive with bevel gear wheel 7, and the output shaft of bevel gear wheel 7 is connected with first order sun gear 9, and first order sun gear 9, first order planet wheel 1, first order ring gear 2 and first order planet carrier 10 connect and compose first order planetary gears; First order ring gear 2 connects firmly with second level sun gear 8 is in the same place; Second level sun gear 8, second level planet wheel 3, second level ring gear 4 and second level planet carrier 5 connect and compose second level planetary gears, and second level planet carrier 5 is fixed, and first order planet carrier 10 connects firmly with second level ring gear 4 is in the same place; Motion and power have realized shunting after through first order planetary gears; A part is through 10 outputs of first order planet carrier, and remainder is delivered to second level sun gear 8 and second level planet wheel 3 through first order ring gear 2 successively, ring gear 4 outputs through the second level.
Described first order planetary gear mechanism, second level planetary gear mechanism adopt the structure of the multirow star-wheel of maximum 7 planet wheels, have improved bearing capacity.
The planet wheel of described first order planetary gear mechanism, second level planetary gear mechanism adopts the compliant pin load balancing structure to come maximized realization load all to carry.
The working principle of the utility model is:
Motion and power are delivered to first order sun gear 9 by bevel pinion 6 inputs through bevel gear wheel 7, thereby get into the first order planetary gears that is made up of first order sun gear 9, first order planet wheel 1, first order ring gear 2 and first order planet carrier 10.Motion has realized shunting with power after through first order planetary gears, and a part is exported through first order planet carrier 10, and remainder is delivered to second level planetary gears through first order ring gear 2.Second level planetary gears is made up of second level sun gear 8, second level planet wheel 3, second level ring gear 4 and second level planet carrier 5.Because first order ring gear 2 connects firmly with second level sun gear 8 and is in the same place, second level planet carrier 5 is fixed, and remainder motion and power are finally via 4 outputs of second level ring gear.Owing to connecting firmly with second level ring gear 4, first order planet carrier 10 is in the same place again, thus the interflow of having realized motion and power.
