Abstract
The utility model discloses a transfer case speed reducer, belongs to the technical field of speed reducers, particularly relates to a shunting gearbox for an excavator and aims to provide a transfer case speed reducer which is small in size and convenient to maintain. The adopted technical scheme is as follows: the transfer case speed reducer comprises a box body, a first shaft, a second shaft, a third shaft, a first-stage cylindrical gear, a first second-stage cylindrical gear and a second second-stage cylindrical gear, wherein the first shaft is arranged on a middle position inside the box body; the second shaft and the third shaft are respectively located at two sides of the first shaft; one end of the first shaft extends out of the side of the box body; one ends of the second shaft and the third shaft extend out of the other side of the box body; the first shaft is provided with the first-stage cylindrical gear; the second shaft is provided with the first second-stage cylindrical gear; the third shaft is provided with the second second-stage cylindrical gear; and the first second-stage cylindrical gear and the second second-stage cylindrical gear are meshed with the first-stage cylindrical gear. The transfer case speed reducer is mainly used for the gearbox of the excavator.
Description
Technical field
The utility model transfer case retarder belongs to the retarder technical field, is specifically related to a kind of excavator and uses the flow deviding type gear-box.
Background technique
Lubricating pump on the excavator need provide power, and this just need dispose retarder on excavator.Two lubricating pumps on the present excavator generally all need provide power separately, retarder and motor that this just needs configuration two covers, and it is big to take up room, and safeguards inconvenient.
The model utility content
The utility model overcomes the deficiency that existing technology exists, and it is little that technical problem to be solved provides a kind of volume, transfer case retarder easy to maintenance.
In order to solve the problems of the technologies described above; The technological scheme that the utility model adopts is: the transfer case retarder; Comprise casing, first, second, the 3rd, primary cylinder gear, the first secondary cylindrical gears and the second secondary cylindrical gears, first neutral position that is installed in box house, second and the 3rd both sides that lay respectively at first; An end of first is stretched out by a side of casing; Second and the 3rd a end is stretched out by another side of casing, primary cylinder gear is installed on first, the first secondary cylindrical gears is installed on second; The second secondary cylindrical gears is installed on the 3rd, and the first secondary cylindrical gears and the second secondary cylindrical gears all mesh with primary cylinder gear.
The beneficial effect that the utility model is compared with prior art had is: two secondary gears and one-level gear engagement are installed in casing; Make a power source send two secondary gears to by the one-level gear; Realize dividing power, not only maintain easily, also saved the space.
Description of drawings
Below in conjunction with accompanying drawing the utility model transfer case retarder is described further.
Fig. 1 is the structural representation of the utility model transfer case retarder.
Fig. 2 is the plan view of the casing of the utility model transfer case retarder.
Among the figure: 1 is casing, and 2 is first, and 3 is second, and 4 is the 3rd, and 5 is primary cylinder gear, and 6 is the first secondary cylindrical gears, and 7 is the second secondary cylindrical gears.
Embodiment
Like Fig. 1, transfer case retarder shown in Figure 2; Comprise casing 1, first 2, second 3, the 3rd 4, primary cylinder gear 5, the first secondary cylindrical gears 6 and the second secondary cylindrical gears 7; Be installed in the neutral position of casing 1 inside for first 2; Second 3 and the 3rd 4 both sides that lay respectively at first 2, an end of first 2 is stretched out by a side of casing 1, and second 3 and the 3rd 4 a end is stretched out by another side of casing 1; Primary cylinder gear 5 is installed on first 2; Be equipped with on second 3 be equipped with on 6, the three 4 of the first secondary cylindrical gearss the second secondary cylindrical gears, 7, the first secondary cylindrical gearss 6 and the second secondary cylindrical gears 7 all with primary cylinder gear 5 engagements.
When the utility model uses; Earlier the utility model is fixed on the excavator; With second 3 of the utility model with the 3rd 4 end that stretches out casing 1 respectively with excavator on two lubricating pumps be connected, again first 2 end that stretches out casing 1 is connected with power source.
When excavator is started working; Power source starts; Drive first 2 and begin to rotate; Because the primary cylinder gear 5 on first 2 with second 3 on the first secondary cylindrical gears 6 and the 3rd 4 on the second secondary cylindrical gears 7 be meshed, so just rely on gear transmission that power has been sent on second 3 and the 3rd 4, and then two lubricating pumps that are connected on second 3 and the 3rd 4 have all obtained power; So just realized that a power source supplies with two different lubricating pumps simultaneously, not only maintained easily but also saved the space.
