Heavy duty transmission for bowl-mill roller crushers
A heavy-duty transmission for the drive of a bowl-mill roller crushers, comprising a bevel gear stage ( 6; 7 ), a horizontal input drive shaft ( 5 ) and a vertical output drive shaft ( 8 ) and a multi stage planetary gearbox arrangement which is connected to the vertical output drive shaft ( 8 ) by a sun pinion ( 9 ) and is connectable to the grinding bowl of the roller mill by an output flange ( 3 ). Planetary wheels ( 10 ) engageable into the sun pinion ( 9 ) are placed on a first plane on a planetary wheel support ( 14 ) which is connected to the output flange ( 3 ). On a second plane, other planetary wheels ( 15 ) are arranged in such a way than the axes of rotation thereof are connected to a gear housing ( 2 ) and which are engageable into a ring gear ( 20 ) connected to the support of the planetary wheels ( 14 ) and are engaged into the sun pinion ( 19 ) of an intermediate gear wheel ( 17 ), which is also provided with a ring wheel ( 18 ) which gearing from outside into the planetary wheels ( 10 ) on the first plane.
1. A heavy-duty transmission for the drive of a bowl-mill roller crusher, comprising:
a bevel gear stage having a horizontal drive shaft and a vertical output shaft;
a multi-stage epicyclic transmission arrangement which is connected to the output shaft via a sun pinion and which can be connected to a grinding bowl of a bowl-mill roller crusher via an output flange;
wherein a first plane, planet wheels which engage in a meshing manner in the sun pinion are arranged on a planet carrier;
wherein the planet carrier is connected to the output flange;
wherein further planet wheels, the axles of which are connected to a transmission housing, are arranged in a second plane, and which engage firstly in a ring wheel connected to the planet carrier and engage secondly in a sun pinion of an intermediate wheel which has a further ring wheel which engages in a meshing manner from the outside in the planet wheels of the first plane.
2. The heavy-duty transmission according to claim 1 , wherein at least three planet wheels are arranged in the first plane.
3. The heavy-duty transmission according to claim 2 , wherein at least three planet wheels are arranged in the second plane.
4. The heavy-duty transmission according to claim 1 , wherein at least three planet wheels are arranged in the second plane.
5. The heavy-duty transmission according to claim 1 , wherein the first plane is arranged above the second plane.
6. The heavy-duty transmission according to claim 1 , wherein said planes are arranged one directly above the other.
7. The heavy-duty transmission according to claim 1 , wherein the planet carrier is designed as a ring wheel within which all of further gearwheels of the epicyclic transmission arrangement are arranged.
