The purpose of this utility model is achieved in that a kind of gear-box for vehicle-mounted fracturing pump, comprise casing, parallel teeth wheel set, planetary gear train, seal arrangement and mounting flange, casing comprises upper box and lower box, it is characterized in that: the parallel teeth wheel set comprises input shaft, input gear and the hollow gear shaft that contains internal spline, input gear is fixedly mounted on input shaft by flat key, and input shaft and hollow gear shaft be the connecting part in upper and lower casing by bearings; Hollow gear shaft and planetary gear train are positioned at same axis, and hollow gear shaft is by the external splines engagement of sun gear in internal spline and planetary gear train; After upper and lower casing is bolted, with ring gear and the mounting flange of planetary gear train, by bolt, be connected successively; In planetary gear train, the output terminal of planet carrier is female splined shaft, the female splined shaft of planet carrier by bearings in mounting flange, the other end of planet carrier by bearings in hollow gear shaft.
In the utility model: contain 3-4 equally distributed planet wheel in the planet carrier of described planetary gear train.
In the utility model: described bearing is spheric roller bearing or deep groove ball bearing; Described bolt is hexagon socket head cap screw, and the connecting part of input shaft and upper lower box is provided with seal arrangement, and the female splined shaft of planet carrier and the connecting part of mounting flange are provided with seal arrangement.
In the utility model: planet carrier docks with the external splines on bent axle in fracturing pump by the internal spline in female splined shaft, and mounting flange is connected with the casing of fracturing pump by bolt.
The utility model has the advantage of: due to the hollow gear shaft that adopts hollow shaft and gear to be solidified as a whole in the parallel teeth wheel set, internal spline in hollow gear shaft output simultaneously, not only reduced the transmission of power link, reduced slippages, rigidity and reliability have been improved, and weight saving, rotary inertia reduces, and has improved transmission efficiency; Because planet carrier one end in planetary gear train is supported on mounting flange, the other end is supported on hollow gear shaft, and the whole axial dimension of gear-box is reduced greatly, weight saving, and compact structure, can install at narrow space, is beneficial to operation in the wild.
