Oil duct on described upper left stiffening rib and the axis of described bearing of input shaft seat are angle; Preferably this angle is less than 5 °;
Oil duct on described upper right stiffening rib and the axis of described bearing of input shaft seat are angle; Preferably this angle is less than 15 °;
The oil duct of described middle right stiffening rib and the axis of described plummer block seat are angle; Preferably this angle is less than 30 °;
Oil duct on the stiffening rib of described lower-left and the axis of described output shaft are angle; Preferably this angle is less than 30 °;
The diameter of described oil duct is no more than 10mm.
Compared with prior art, the utlity model has following advantage:
1, because described casing internal oil channel is positioned at stiffening rib, casing is not done to large change, thereby can not affect the original rigidity of casing and intensity, both guaranteed good radiating effect, improved again the working life of branch mailbox;
2,, because oil duct diameter is no more than 10mm, the bearing support axis that simultaneously each oil duct and its will be lubricated has a certain degree, thereby has good lubrication effect.
2, because described casing internal oil channel is positioned at stiffening rib, casing is not done to large change, thus simple in structure, easy processing.
Accompanying drawing explanation
Fig. 1 is the utility model speed changer transfer case lubricating structure schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Shown in Figure 1, a kind of speed changer transfer case lubricating structure of the present utility model, comprise casing 1, be installed on the bearing of input shaft seat 9 on casing 1 successively, plummer block seat 11 and output shaft bearing seat 13, described casing 1 is provided with upper left stiffening rib 1-8, upper right stiffening rib 1-7 with bearing of input shaft seat 9 axis joints, be provided with middle right stiffening rib 1-9 with plummer block seat 11 axis joints, be provided with lower-left stiffening rib 1-10 with output shaft bearing seat 13 joints, casing 1 is inner has oil sump 1-3 near output shaft bearing seat 13 places, it is characterized in that; On described upper left stiffening rib 1-8, upper right stiffening rib 1-7, middle right stiffening rib 1-9 and lower-left stiffening rib 1-10, be respectively equipped with at least one oil duct 1-2, every oil duct 1-2 starts from described casing 1 edge, in the endoporus of bearing of input shaft seat 9, plummer block seat 11 and output shaft bearing seat 13, stop, and in described casing 1 corresponding section, edge, is provided with oil trap 1-1.This structure of the present invention, make speed changer transfer case lubricating structure of the present invention only need do less change to the casing of prior art, on corresponding stiffening rib, process corresponding oil duct and on casing, process corresponding oil trap, just can make lubricant oil realize good circulation, take away while working running together with gear and bearing etc., reduce the heat shedding and in transfer case body, form high temperature, whole transfer case is worked under good temperature environment, thereby can meet preferably lubricated and dispel the heat when requiring, improve working life.
