Description
Technical field
The utility model relates to the driving speed reducer device on a kind of caterpillar machinery equipment, is specifically a kind ofly convenient to the caterpillar machinery driving speed reducer Split flange dish structure changing the easily damaged partss such as large oil sealing.
Background technique
Because caterpillar machinery working environment is relatively severe, the driving speed reducer being arranged on chassis works in the environment of silt of being everlasting, dust, and therefore oil sealing is easy to be subject to the invasion and attack of silt and dust and lost efficacy.What mostly adopt in the market is Integral flange structure, the drawback of this kind of flange plate is to change the suitable trouble of oil sealing, must take apart successively from driving speed reducer bonnet, the special tool removing locking nut must be needed, therefore driving speed reducer occurs that oil sealing leaks oil condition, be mostly return factory to remove replacing, not only reduce working efficiency like this, and add labour cost.
As shown in Figure 3, be a kind of Integral flange structural drawing, it comprises Integral flange d; Integral flange d is provided with bearing support a, large bearing b, little bearing c, locating stud e, locking nut f and oil sealing g, current crawler-type traveling speed reducer mostly adopts this kind of structure, under oil sealing g occurs leaking oil condition, its drawback will reveal: when changing oil sealing g, first need with special tool electric drill or drilling machine, locating stud e destructiveness to be removed, then screw out locking nut f, again separate bearing support a and large and small bearing b, c, finally could change oil sealing g.
Its drawback is:
(1) during replacing oil sealing, operation is more;
(2) cause some component permanent damages, such as locating stud e, locking nut f, must change together;
(3) secondary is dismantled, is installed large and small bearing b, c, not only can affect the operating life of large and small bearing b, c, and likely cause the damage of bearing;
(4) add the labour cost of workman, reduce the working efficiency of driving speed reducer.
Summary of the invention
For solving the problems of the technologies described above, the utility model, according to the structural feature of driving speed reducer, announces a kind of caterpillar machinery driving speed reducer Split flange dish structure being convenient to change the easily damaged partss such as large oil sealing.
The utility model by following be technological scheme realize: a kind of caterpillar machinery driving speed reducer Split flange dish structure, comprises Split flange dish; Described Split flange dish is provided with bearing support; Oil sealing, large bearing and little bearing are installed successively from the bottom to top between Split flange dish and bearing support; Described Split flange dish comprises lower disk body and is fixed on the upper disk body on lower disk body; Described oil sealing is arranged between lower disk body and bearing support; Described large bearing and little bearing are arranged between disk body and bearing support.
It is further: the lower disk body of described Split flange dish has seam, and described upper disk body lower end is embedded on lower disk body seam.
The lower end surface of the lower disk body of described Split flange dish has screw mounting hole, has corresponding tapped hole at upper disk body, and upper disk body is connected with lower disk body by screw.
Under described Split flange dish, the screw mounting hole of disk body is stepped counterbore.
O type circle is provided with between the lower end surface of the lower disk body of described Split flange dish and upper disk body.
Described screw is positioned at the outside of O type circle.
The utility model is when oil sealing changed by needs, as long as screw out screw with spanner, separately Split flange dish just can change oil sealing easily.Compare Integral flange structure, the advantage of Split flange dish structure is:
(1) dismounting is simple;
(2) locating stud, locking nut can not be caused to damage; Secondary dismounting bearing is not needed yet;
(3) save labour cost, working efficiency is provided;
(4) Split flange dish manufacture cost is also relatively low.
The design of model utility Split flange dish structure is convenient to change the easily damaged partss such as large oil sealing, thoroughly solves the difficult problem changing oil sealing difficulty, and structure is simple, easy to utilize, saves labour cost, increases work efficiency.
