Description
Technical field
The utility model relates to a kind of gear-box that is exclusively used in cement grinding mill, especially a kind of center transmission epicyclic gearbox of cement grinding mill.
Background technique
At present, cement grinding mill generally all adopts the parallel-axes gears reduction gearing mechanism with gear-box, and transmission speed ratio is less, and volume is also bigger, promptly adopts two-stage parallel axis gear reduction driving mechanism, or three grades of parallel-axes gears reduction gearing mechanisms.Wherein, parallel teeth wheel sets at different levels all adopt power dividing mechanism, and power dividing is most uses rich property axle construction to realize all carrying.For requiring large speed ratio, powerful cement grinding mill gear-box, the general required parallel teeth wheel set facewidth and centre distance are all bigger, and the boundary dimension of complete machine is also bigger, when Environmental Conditions is narrow and small, has had a strong impact on the installing space of miscellaneous equipment.How when reducing speed reducer boundary dimension, can also improve the ability of the output torque and the transmission speed ratio of speed reducer, and the reliability of all carrying, and can reduce cost, the problem that people pay close attention to become.
The model utility content
The purpose of this utility model is: all bigger with the parallel teeth wheel set facewidth and the centre distance that gear-box exists at cement grinding mill, the practical problem that the boundary dimension of complete machine is also bigger provides a kind of cement grinding mill center transmission epicyclic gearbox.
The purpose of this utility model is achieved in that cement grinding mill center transmission epicyclic gearbox, it is characterized in that:
Casing comprises first casing, second casing and the 3rd casing, wherein, is provided with first order planetary mechanism between first casing and second casing; Be provided with first order planetary mechanism between second casing and the 3rd casing;
Input gear shaft one end is connected with first order sun gear in the first order planetary mechanism; The first order planet carrier of first order planetary mechanism is connected with second level sun gear in the planetary mechanism of the second level; The second level planet carrier of second level planetary mechanism is connected with the output shaft of concentric.
In the utility model: input shaft one end is provided with inner spline housing, and an end of first order sun wheel shaft is provided with spline, and input shaft is connected with spline by described inner spline housing with first order sun gear; First order planet carrier center is provided with inner spline housing, and an end of second level sun wheel shaft is provided with spline, and first order planet carrier is connected with spline by described inner spline housing with second level sun gear; Second level planet carrier and output shaft welding.
In the utility model: planet carrier two ends, the second level respectively by bearings in second casing and the 3rd casing; In first casing, in the 3rd casing, the bearing of input shaft and the output shaft outside is equipped with seal ring to output shaft to input shaft by bearings by bearings.
Advantage of the present utility model is, because employing two-stage sun train, and input shaft and the setting of output shaft concentric, not only reduced speed reducer boundary dimension, can also improve the output torque and the transmission speed ratio of speed reducer; Because second level ring gear in first order sun train and the second level sun train and second level ring gear all as the part of casing, make overall structure compact more.
