Specific embodiment
The following is specific embodiments of the present invention and with reference to attached drawing, technical scheme of the present invention is further described,
But the present invention is not limited to these embodiments.
Technical solution provided by the invention is illustrated in more detail with reference to Fig. 1 to Fig. 6.
As shown in Figures 1 to 6, this compact profile shaft flow hydraulic axial plunger pump includes：
Housing 10；
Rear cover 20 and housing 10 surround to form installation space, and cylinder body 30 is equipped in installation space；
Transmission shaft 40 across housing 10 and stretches into the closely connection of installation space and cylinder body 30, and the transmission shaft 40 passes through cylinder
Body 30 is simultaneously contacted with rear cover 20, and the transmission shaft 40 is set as oil distribution shaft structure, and in 30 docking location of transmission shaft 40 and cylinder body
Equipped with chute 41；
Hydraulic lock repairing check valve 50 and safety overflow valve 60 are integrated on rear cover 20.
The present invention protects a kind of compact profile shaft flow hydraulic axial plunger pump, is a kind of compact profile shaft flow for yacht
The 80 formula steering gear of hydraulic axial plunger, integral structure layout is compact, and 20 integrated hydraulic of rear cover lock repairing check valve 50 and safety are overflow
Valve 60 is flowed, self-locking and defencive function can be provided to perform oil cylinder；The steering gear is the steering gear of manipulation one, which is grasped by people
Power oil sources after work is provided and realizes turning function again, general steering gear is to need to realize to be turned by other oil sources offer power
To function；The problem of pump uses axis flow form, and plunger pump volumetric efficiency is low when can solve the slow-speed of revolution, and axis is matched
Stream is compact compared to disk distributing construction.
In the present case, the compact profile shaft flow hydraulic axial plunger pump power density is big, housing 10, rear cover 20, transmission shaft
40 grades are all using aluminum material, and whole pump is light-weight, but pressure is suitable with the steering gear of equal volume.
