Description
Technical field
It the utility model is related to deceleration device technical field, more particularly to a kind of dynamicliquid pressure deceleration device.
Background technology
In the prior art, deceleration device is commonly used in engine being changed into water by the output shaft power that rotation is spread out of at a high speed
The low speed rotation of pump input shaft, traditional deceleration device generally realizes the adjusting of speed using reducing gears such as gear pairs, this
Traditional deceleration device can not ensure the uniform rotation that the power-conversion of engine outflow is pump shaft, and this traditional deceleration
Device can not also be effectively reduced engine speed.
The content of the invention
The purpose of this utility model is to provide a kind of dynamicliquid pressure deceleration device, the technical problem to be solved is that how
Engine speed is effectively reduced, and the uniform rotation that the power-conversion for spreading out of engine is pump shaft.
Dynamicliquid pressure deceleration device described in the utility model includes babinet, and the babinet is by upper box and lower box group
Into the closed position between upper box and lower box is provided with fluid sealant and shim liner, and the babinet is hollow, described nowel
Petroleum pipeline inlet tube is provided with body, petroleum pipeline oil return pipe is provided with the upper box；The babinet is provided centrally with
Two connecting shafts, the one end of the connecting shaft stretch out upper box top surface and with the output axis connection of engine；The connection
The other end of axis stretches out the bottom surface of lower box and is connected with pump case impeller, and reduction gearing collection is internally provided with the babinet
Into, the reduction gearing integrate by the 3rd ratio wheel, the 4th the first ratio wheel being connected from ratio wheel and with engine and
Connecting shaft, the second ratio wheel being connected with pump case impeller and connecting shaft composition.
Preferably, the petroleum pipeline inlet tube is arranged on the side of the lower box.
Preferably, the petroleum pipeline oil return pipe is arranged on the top of the upper box.
Preferably, it is provided with coldplate on the outer circumferential surface of the upper box and lower box.
Preferably, the shim liner is ox-hide paper gasket.
The technical solution of the utility model has the following advantages that：
Dynamicliquid pressure deceleration device one end described in the utility model connects pump case impeller, and one end connection engine can
Engine speed is effectively reduced, makes the uniform rotation that the power-conversion that engine is spread out of is pump shaft.
Brief description of the drawings

Fig. 2 is the internal structure schematic diagram of the dynamicliquid pressure deceleration device.
Fig. 3 is that the dynamicliquid pressure deceleration device reduction gearing integrates.
Embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Fig. 1 and Fig. 2, Fig. 3, dynamicliquid pressure deceleration device described in the utility model includes babinet 1, the case
Body is made of upper box and lower box, and the closed position between upper box and lower box is provided with fluid sealant 5 and shim liner 6, institute
It is hollow to state babinet 1, and petroleum pipeline inlet tube 4 is provided with the lower box, and petroleum pipeline is provided with the upper box and is returned
Oil pipe 3；The babinet is provided centrally with connecting shaft 21 and 22, described 22 one end of connecting shaft stretch out the top surface of upper box and with
The output axis connection of engine；The other end of the connecting shaft 21 stretches out the bottom surface of lower box and is connected with pump case impeller,
The reduction gearing that is internally provided with of the babinet integrates 8, and the reduction gearing is integrated by the 3rd ratio wheel the 9, the 4th from deceleration
Wheel 10 and the first ratio wheel 12 and connecting shaft 22 that are connected with engine, the second ratio wheel 11 for being connected with pump case impeller and
Connecting shaft 21 forms.When the engine output speed moment increase of deceleration device connection is too fast, the first ratio wheel deceleration 12
The third and fourth ratio wheel 9 and 10 is driven to slow down successively, the third and fourth ratio wheel 9 and 10 drives the second ratio wheel to slow down, and subtracts
It is the 1/5 of initial velocity after speed, pump case wheel rotation is driven by connecting shaft 21.
Preferably, the petroleum pipeline inlet tube 4 is arranged on the side of the lower box.
Preferably, the petroleum pipeline oil return pipe 3 is arranged on the top of the upper box.
Preferably, it is provided with coldplate 7 on the outer circumferential surface of the upper box and lower box.
Preferably, the shim liner 6 is ox-hide paper gasket.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will
Seek the scope of protection.
