The purpose of this utility model is achieved in that a kind of multistage planet speed reducer for pebble mill, comprise and be fixed with on casing, input gear shaft, driven shaft, the driven shaft and import the intermeshing driven gear of gear shaft, it is characterized in that: also comprise middle planetary train and the output planetary train of series connection, concrete structure is:
A) described casing comprises preceding casing, middle casing and rear box, middle ring gear in the middle planetary train is between preceding casing and middle casing, output ring gear in the output planetary train is between middle casing and rear box, and preceding casing, middle ring gear, middle casing, output ring gear, rear box are tightly connected in regular turn mutually;
B) input gear shaft, driven shaft are arranged in preceding casing, driven shaft one end is provided with internal tooth casing, by the middle sun wheel shaft in the internal tooth casing driving middle planetary train of driven shaft end, again by the output sun wheel shaft in the middle planetary frame driving output planetary train of middle planetary train;
C) input gear shaft and driven gear all adopt herringbone tooth;
D) input gear shaft one end stretches out preceding casing, and the output planetary frame in the output planetary train passes through rear box, and its end is provided with output flange;
E) input gear shaft and preceding casing intersection, and output planetary frame and rear box intersection are equipped with seal arrangement.
In the utility model: the herringbone tooth on input gear shaft and the driven gear is the involute profile herringbone tooth.
In the utility model: comprise three equally distributed planet wheel shafts in described middle planetary train and the output planetary train on the corresponding planet carrier at least, planet wheel shaft is provided with the planet wheel of bearings.
In the utility model: the bearing that supports planet wheel is implemented pressure lubrication by the oil duct in casing and planet carrier, the planet wheel shaft.
In the utility model: input gear shaft, driven shaft, middle planetary frame and output planetary frame all by bearings in casing, described in the middle of sun wheel shaft and output sun wheel shaft all float.
In the utility model: the bearing that supports input gear shaft, driven shaft, middle planetary frame and output planetary frame is all implemented pressure lubrication by the oil leab in the casing.
Advantage of the present utility model is: because the retarder input stage adopts the herringbone tooth wheel set, improved input bearing capacity and transmission stability; Owing to adopted multistage planet train series model, planetary mechanisms at different levels all adopt the multirow star-wheel power dividing of three planet wheels at least, can improve greatly and all carry performance, reduce diameter, the facewidth of gear pair, and transmission speed ratio and the output torque of speed reducer are provided significantly, reduced the volume and weight of complete machine simultaneously; Because the ring gear of planetary mechanisms at different levels makes overall structure compacter all as the part of casing; Because the bearing to each motive position has all adopted pressure lubrication, make the lubricated and work of complete machine more reliable.
