Make pressure set points substantially close to the hydraulic motor maximum pressure limit, pressure security margin reserves deficiency, is excavating high impact forces
Under load working condition in use, hydraulic motor superpressure using when be easy to cause hydraulic motor and be damaged；
Second using huge discharge fluid motor-driven single input mouth excavation gear reducer, the excavation gear reducer of the drive form
It is simple in structure, and hydraulic motor pressure and rotating speed safe clearance have been slightly increased, but due to huge discharge hydraulic motor rotor matter
Amount is big, and limit speed is relatively low, causes hydraulic motor pressure and the increase of rotating speed safe clearance limited, and huge discharge hydraulic motor valency
Lattice are expensive, scheme overall economy quality deficiency；
The third excavates gear reducer using double excavation motor driving lose-lose entrances.Although the drive form employs double motor
Drive form, allow excavator motor type selecting reserve larger pressure and with rotating speed safe clearance.But due to the drive form
Two input ports need to be set by excavating gear reducer, for installing two hydraulic motors, so as to cause the drive form to excavate gear reducer
It is complicated, scheme overall economy quality deficiency.
The content of the invention
The drawbacks of the purpose of this utility model is to overcome above-mentioned excavation gear reducer drive form, there is provided one kind is applied to iron
Concatenation type hydraulic motor on way tiny fragments of stone, coal, etc. cleaning car excavator, the concatenation type hydraulic motor structure more compact and reasonable, excavates horse
It is sufficient up to pressure, rotating speed safe clearance, and make driving device overall economy quality more excellent.
The technical solution of the utility model is：A kind of concatenation type hydraulic motor for railway ballast cleaning car excavator,
Including the first hydraulic motor, the second hydraulic motor, ring flange, bolt, locating slot, hydraulic motor axis, inner spline housing, end cap, circle
Hole and groove.
The concatenation type hydraulic motor being used on railway ballast cleaning car excavator, in the first hydraulic motor and second
Second flange is equipped between hydraulic motor；Second flange is equipped with uniformly distributed screw hole, and the first hydraulic motor lower end is equipped with and is linked as one
The first flange disk of first hydraulic motor lower end and second flange, are installed together by the first flange disk of body with the first bolt；
Second hydraulic motor upper end cover is equipped with uniformly distributed screw hole, and flange and the second hydraulic motor upper end cover are crossed by second with the second bolt
It is installed together.
First hydraulic motor lower end first flange disk center is equipped with circular protrusions seam allowance, and second flange center is equipped with groove；
Inner spline housing is in the first center hole of second flange and the second center hole of the second hydraulic motor upper end cover, the first liquid
The upper spline of the lower spline of the axis of pressure motor and the second hydraulic motor axis is inserted into inner spline housing respectively, by the first hydraulic motor
Axis and the installation of the second hydraulic motor axis link together；Concatenation type hydraulic pressure horse of the composition applied to railway ballast cleaning car excavator
Reach.
The seam allowance and groove：Circular protrusions seam allowance and groove are used to pacify the first hydraulic motor and the second hydraulic motor
Set position.
The railway ballast cleaning car excavator：The second hydraulic motor lower flange is subtracted with excavation by the 3rd bolt
Fast machine is installed together, and forms railway ballast cleaning car excavator.
The beneficial effects of the utility model are：, will applied to the concatenation type hydraulic motor of railway ballast cleaning car excavator
First hydraulic motor and the second hydraulic motor concatenation are installed together, and structure more compact and reasonable is easy to maintenance, with same power
Single fluid motor-driven is compared, and concatenation type hydraulic motor pressure, rotating speed surplus are more sufficient, and power and liquid are excavated so as to improve
Pressure motor service life, and overall economy quality is good.
