Description
Technical field
It is specifically a kind of to be applied to railway ballast cleaning car excavator the present invention relates to a kind of concatenation type hydraulic motor
Concatenation type hydraulic motor.
Background technology
Excavating reductor using fluid motor-driven at present substantially has following three kinds of forms：
The first excavates speed reducer structure letter using small displacement fluid motor-driven single input mouthful excavation reductor, the drive form
It is single, and small displacement motors are cheap, but in order to reach that the high power requirements of reductor, motor highest work pressure are excavated in driving
Power setting value is substantially close to the hydraulic motor maximum pressure limit, and pressure security margin reserves are not enough, is excavating high impact forces load
In use, hydraulic motor superpressure is easily caused hydraulic motor when using is damaged under operating mode；
Second using huge discharge fluid motor-driven single input mouthful excavation reductor, the excavation speed reducer structure of the drive form
Simply, and it has been slightly increased hydraulic motor pressure and rotating speed safe clearance, but because huge discharge hydraulic motor rotary protonatomic mass is big,
Limit speed is relatively low, causes hydraulic motor pressure and rotating speed safe clearance to increase limited, and huge discharge hydraulic motor price is high
Expensive, scheme overall economy quality is not enough；
The third excavates reductor using double excavation motor driving lose-lose entrances.Although the drive form employs double motor driving
Form, allow excavator motor type selecting reserve larger pressure and with rotating speed safe clearance.But because the drive form is excavated
Reductor need to set two input ports, for installing two hydraulic motors, so as to cause the drive form to excavate speed reducer structure
Complexity, scheme overall economy quality is not enough.
The content of the invention
The drawbacks of purpose of the present invention is to overcome above-mentioned excavation reductor drive form is applied to railway road there is provided one kind
The concatenation type hydraulic motor of tiny fragments of stone, coal, etc. cleaning car excavator, the concatenation type hydraulic motor structure more compact and reasonable, excavation motor pressure,
Rotating speed safe clearance is sufficient, and makes drive device overall economy quality more excellent.
The technical scheme is that：A kind of concatenation type hydraulic motor for railway ballast cleaning car excavator, including
First hydraulic motor, the second hydraulic motor, ring flange, bolt, locating slot, hydraulic motor axle, inner spline housing, end cap, circular hole and
Groove.
The described concatenation type hydraulic motor being used on railway ballast cleaning car excavator, in the first hydraulic motor and second
Second flange is provided between hydraulic motor；Second flange is provided with uniform screw, and the first hydraulic motor lower end is provided with and is linked as one
The first flange disk and second flange of first hydraulic motor lower end, are installed together by the first flange disk of body with the first bolt；
Second hydraulic motor upper end cover is provided with uniform screw, 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 provided with circular protrusions seam, and second flange center is provided 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 axle of pressure motor and the second hydraulic motor axle is inserted into inner spline housing respectively, by the first hydraulic motor
Axle and the second hydraulic motor axle, which are installed, to link together；Concatenation type hydraulic pressure horse of the composition applied to railway ballast cleaning car excavator
Reach.
Described seam and groove：Circular protrusions seam and groove are used to pacify the first hydraulic motor and the second hydraulic motor
Set position.
Described 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 constitutes railway ballast cleaning car excavator.
The beneficial effects of the invention are as follows：Applied to the concatenation type hydraulic motor of railway ballast cleaning car excavator, by 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 list liquid
Pressure motor driving is compared, and concatenation type hydraulic motor pressure, rotating speed surplus are more sufficient, so as to improve excavation power and hydraulic pressure horse
Up to service life, and overall economy quality is good.
