Description of drawings
Fig. 1 is the cross-sectional view of the embodiment of a kind of whole drive mechanism of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.
As shown in Figure 1, the embodiment of a kind of whole drive mechanism of the utility model wherein, comprises Spur Gear Driving module, driving shaft 1, Planetary Gear Transmission module and drive hub 2; The Spur Gear Driving module connects an end of power source (not drawing) and driving shaft 1 in figure, make the power of power source be passed to driving shaft 1 after slowing down; The Planetary Gear Transmission module connects driving shaft 1 dorsad an end and the drive hub 2 of Spur Gear Driving module, makes the power of driving shaft 1 be passed to drive hub 2 after slowing down; Drive hub 2 outer rims are connected with to drive the tooth piece 21 of crawler belt (not drawing) in figure.
The operating principle of technique scheme is that the Spur Gear Driving module by the first order is passed to driving shaft 1 with the power of power source after slowing down, again by the Planetary Gear Transmission module with driving shaft 1 dynamic retarding after be passed to drive hub 2, owing to do not re-use semi-axis structure, make the whole drive mechanism after the improvement overcome the defective that former semi-axis structure brings.A kind of more excellent embodiment is that the Spur Gear Driving module can mainly be formed with the gear wheel 52 that is connected with driving shaft 1 by the pinion 51 that is connected with power source, pinion 51 and gear wheel 52 engagements.
On the technique scheme basis, further, also comprise columnar driving shaft support 3, driving shaft support 3 centers are provided with through hole 31, the through hole 31 interior and nearly Spur Gear Driving module places that driving shaft 1 is sheathed on driving shaft support 3 are connected with driving shaft support 3 by bearing 41, drive hub 2 is sheathed on the driving shaft support 3 by cone bearing 42, and the Planetary Gear Transmission module is contained in the drive hub 2.The Planetary Gear Transmission module is contained in makes whole whole drive mechanism compacter in the drive hub 2.
On the technique scheme basis, further, also comprise housing 6, housing 6 is connected with the end of driving shaft support 3 near the Spur Gear Driving module, the Spur Gear Driving module is contained in the housing 6, housing 6 is provided with to connect the syndeton 61 of the gear in the Spur Gear Driving module, and the gear in the Spur Gear Driving module is connected with syndeton 61 on the housing 6 by bearing 43.Simultaneously, syndeton (not drawing) in order to be connected with frame also can be set on the housing 6 in figure.Housing 6 holds whole Spur Gear Driving module, and is connected with the frame of bulldozer, and the Spur Gear Driving module is protected, and avoids impaired under the abominable working environment of bulldozer.
