Abstract
The utility model relates to an oil pump hydraulic motor assembly, it includes hydraulic motor, link and fuel pump assembly, fuel pump assembly constitute by air -vent valve and oil pump, first oil duct and second oil duct have been seted up to one side of oil pump, first oil duct with the inner chamber intercommunication of oil pump, the pressure oil export on the casing of second oil duct and oil pump communicates, the oil duct mouth of first oil duct and second oil duct respectively with the air -vent valve on oil inlet and oil -out butt joint, the tip of hydraulic motor's transmission shaft is hollow structure, and hydraulic motor is connected with the link, and fuel pump assembly is connected with the link, the key -type connection cartridge is passed through in the hollow structure of transmission shaft to the axis of rotation of oil pump. The utility model discloses change the inside connection of traditional oil pump, changed the connection structure between oil pump and the motor simultaneously for oil pump motor assembly bulk reduction, weight loss, the leak source is few, and can realize the pressure energy of output variable.
Description
Technical field
This utility model belongs to hydraulic test and in particular to a kind of oil pump hydraulic motor assembly.
Background technology
Traditional oil pump of hydraulic motor assembly is to be connected by shaft coupling with motor, and needs between oil pump and overflow valve
To be attached by an intermediate transit plate, to be also required to more external pipeline during fluid circulation and be attached.This does not only result in
Whole body type takes up room greatly, and because pipeline is many, the leak source causing is also many, also more complicated during installation.
Content of the invention
The purpose of this utility model is to provide a kind of oil pump hydraulic motor assembly.This utility model changes traditional oil pump
Internal connection, changes the attachment structure between oil pump and motor so that oil pump motor assembly volume reduces, weight subtracts simultaneously
Gently, leak source is few, and can achieve the pressure energy of outfan variable.
The technical solution adopted in the utility model：Oil pump hydraulic motor assembly, it includes hydraulic motor, link and oil pump
Assembly, described oil pump assembly is made up of pressure regulator valve and oil pump, and the side of described oil pump offers the first oil duct and the second oil duct,
First oil duct and the inner space of described oil pump, the pressure oil outlet on the housing of the second oil duct and oil pump, described first
The oil duct junction of oil duct and the second oil duct is docked with the oil-in on pressure regulator valve and oil-out respectively；The power transmission shaft of described hydraulic motor
End be hollow structure, hydraulic motor is connected with link, and oil pump assembly is connected with link, and the rotary shaft of described oil pump is logical
Cross in the bonded hollow structure being inserted into power transmission shaft.
Further, by support base, cross bracing frame and axle sleeve, one becomes described link from down to up respectively
Type, the middle part of axle sleeve offers one and supplies the hollow structure that hydraulic motor power transmission shaft and oil pump rotary shaft pass through.
Further, described oil pump is vane-type oil pump.
Compared with prior art its advantage is this utility model：This utility model is by carrying out to oil pump internal structure
Improve, increased two oil duct pipelines in oil pump, it is to avoid traditional oil pump exterior line is crossed-over the trouble brought,
When on traditional oil pump, transfer block connects, because oil-collecting hole is more simultaneously, lead to leak source more so that oil pump later period maintenance cost relatively
Greatly, structure of the present utility model eliminates this structure of transfer block, reduces leak source, and structural volume reduces, weight saving；This reality
Replace with hollow rotating shaft with the solid rotary shaft of new conventional motor, the rotary shaft of oil pump is directly inserted into the hollow axle of motor
Interior, eliminate using this structure of shaft coupling, decrease manufacturing cost, further reduce final assembly size simultaneously so that
Assembling is installed very convenient.
Brief description
Fig. 1 is attachment structure schematic diagram of the present utility model；
Fig. 2 is the installation site structural representation of pressure regulator valve on oil pump in this utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of oil pump hydraulic motor assembly, it includes hydraulic motor 1, link 2 and vane type oil
Pump group part, described oil pump assembly is made up of pressure regulator valve 4 and oil pump 3, and the side of described oil pump 3 offers the first oil duct 5 and
Two oil ducts 6, the inner space of the first oil duct 5 and described oil pump 3, the pressure oil export 7 on the housing of the second oil duct 6 and oil pump 3
Connection, the oil duct junction of described first oil duct 5 and the second oil duct 6 is docked with the oil-in on pressure regulator valve 4 and oil-out respectively；Described
The end of the power transmission shaft 8 of hydraulic motor 1 is hollow structure, and hydraulic motor 1 is connected with link 2, and oil pump assembly is with link 2 even
Connect, the rotary shaft of described oil pump 3 is passed through key 9 connection and is inserted in the hollow structure of power transmission shaft 8.
Wherein, described link 2 is respectively by support base 10, cross bracing frame 11 and axle sleeve 12 one from down to up
Molding, the middle part of axle sleeve 12 offers one and supplies the hollow structure that hydraulic motor 1 power transmission shaft 8 and oil pump 3 rotary shaft pass through.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in
Other related technical fields, are all included in the same manner in scope of patent protection of the present utility model.
