Abstract
The utility model relates to a transfer case, in particular to a single motor transfer case of a heading machine, which comprises an input end and more than two output ends. The input end of the transfer case is connected with an output end of a power mechanism. According to the technical scheme that the input end and more than two output ends are arranged on the transfer case, the power mechanism can provide power to the input end of the transfer case, and then at least more than two output powers are resolved after the power passes through the transfer case, thereby the transfer case can save arrangement of power mechanisms, simplify structure and save space as the outer dimension of the transfer case is reduced.
Description
Technical field
The utility model relates to a kind of transfer case, just relates to a kind of single motor transfer case of development machine specifically.
Background technology
At present, the dynamical system of down-hole development machine and water system all adopt fire-proof motor to drive, because the executive component of development machine is a lot, there are inconvenient operation or unbalanced shortcoming, at this moment need to adopt two groups of hydraulic pumps could satisfy the power requirement of executive component, development machine needs to adopt three fire-proof motors to drive altogether like this, wherein two fire-proof motors drive two groups of hydraulic pumps, a fire-proof motor drives a water pump, though the power requirement of having satisfied executive component is set like this, but because the increasing of electrical part, make the deterioration of safety of development machine; Arrange that simultaneously three fire-proof motors make the development machine structure become complicated and in disorder, wasted space and position that machine is arranged,, had only the lengthening machine because underground equipment is very strict to width and requirement for height, this just causes machine to reduce in the flexibility of down-hole running, is difficult for controlling.
Summary of the invention
The purpose of this utility model just provides a kind of novel development machine list motor transfer case, and this transfer case is provided with an input and some outputs, simple in structure and saving space.
For achieving the above object, the utility model has adopted following technical scheme: transfer case is provided with an input and plural at least output, and the input of transfer case links to each other with the output of actuating unit.
As shown from the above technical solution, the utility model is by an input of transfer case and the setting of at least two above outputs, be that actuating unit provides the input of power to transfer case, behind transfer case, can decomposite plural at least outputting power, the setting of having saved actuating unit makes structure become simple, on appearance and size, also reduce to some extent simultaneously, saved the space.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model oil sump position.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of development machine list motor transfer case as shown in Figure 1, transfer case 10 is provided with an input and plural at least output, and its input links to each other with the output of actuating unit.
As preferred version of the present utility model, need adopt the requirement of two groups of hydraulic pumps and a water pump at present at the down-hole development machine, transfer case 10 in this preferred version is provided with an input and three outputs, this input links to each other with the output of fire-proof motor 40, and three outputs drive the first hydraulic pump 20A, the second hydraulic pump 20B and water pump 30 rotations respectively.
Described transfer case 10 comprises an input gear 11, adopts shaft coupling 50 to link to each other between input gear 11 and the fire-proof motor 40, and the axial line of importing the output shaft 41 of the axial line of gear 11 and fire-proof motor 40 matches.
The upper and lower of input gear 11 is respectively equipped with first output gear 12 and second output gear 13 with its external toothing, the diameter of first output gear 12 and second output gear 13 is less than the diameter of input gear 11, and the output shaft of first output gear 12 and second output gear 13 drives the first hydraulic pump 20A respectively and the second hydraulic pump 20B rotates; Input gear 11 directly drives water pump 30 and rotates, and the employing key is connected between the output of input gear 11 and the water pump 30, can be spline connection or flat key connection etc.
As preferred version of the present utility model, the diameter of first output gear 12 and second output gear 13 is less than the diameter of input gear 11, promptly drive the effect that first output gear 12 and second output gear, 13 these two pinions play a speedup transmission by input gear 11 these gear wheels, can suitably be improved the rotating speed of fire-proof motor 40, to satisfy the demand of the first hydraulic pump 20A and the second hydraulic pump 20B.
An input and three outputs of transfer case 10 are exactly specifically, one epitaxial lateral overgrowth of input gear 11 is stretched axle is arranged, this links to each other with an end of shaft coupling 50, the other end of connecting axle 50 links to each other with the output shaft 41 of fire-proof motor 40, the another side of input gear 11 is provided with axis hole, this axis hole links to each other with the rotating shaft of water pump 30, import simultaneously gear 11 on, the below is respectively equipped with first output gear 12 and second output gear 13 with its external toothing, first output gear 12 links to each other with the rotating shaft of the first hydraulic pump 20A and the second hydraulic pump 20B respectively with the second output output gear 13, realizes that one of transfer case 10 advances three and goes out.
As shown in Figure 2, as preferred version of the present utility model, because the power of all transmissions all concentrates on output on the transfer case 10, moment of torsion is very high, so be provided with heat abstractor below transfer case 10, the heat abstractor that present embodiment is selected for use is an oil sump 50, can effectively increase the oil mass and the area of dissipation of gear oil by oil sump 50, improved the application life of gear, bearing and sealing ring, thereby improved the application life of transfer case 10.
In sum, the utility model advances three by one of transfer case 10 and goes out structure, promptly drives the first hydraulic pump 20A, the second hydraulic pump 20B and water pump 30 simultaneously with a fire-proof motor 40, in the quantity that has reduced fire-proof motor 40, has also improved safety; Owing to reduced the quantity of fire-proof motor 40, make the appearance and size of development machine diminish, saved the space, increased the flexibility of underground work, maintain easily simultaneously and maintain.
